I have a lot of dreams. 29 00:01:05,120 --> 00:01:06,559 I spent a lot of time just sitting around 30 00:01:06,560 --> 00:01:08,629 dreaming, and I used 31 00:01:08,630 --> 00:01:10,249 to have very little money all my life, 32 00:01:10,250 --> 00:01:12,469 you know, practically no money. 33 00:01:12,470 --> 00:01:14,389 So with dreams and no money, you learn to 34 00:01:14,390 --> 00:01:15,359 scrounge. 35 00:01:15,360 --> 00:01:16,819 You're really never into scrounging. 36 00:01:16,820 --> 00:01:18,169 When you find something, you're willing 37 00:01:18,170 --> 00:01:19,309 to fix it. 38 00:01:19,310 --> 00:01:21,439 And and when you fixed it, 39 00:01:21,440 --> 00:01:22,679 you don't want to break anymore. 40 00:01:22,680 --> 00:01:24,109 So you sort of become attached to things 41 00:01:24,110 --> 00:01:25,519 you got. That's me. 42 00:01:25,520 --> 00:01:27,739 And then you develop 43 00:01:27,740 --> 00:01:29,689 the ability to fix anything, which I 44 00:01:29,690 --> 00:01:31,219 think I have today practically anything 45 00:01:31,220 --> 00:01:32,209 if I really want. 46 00:01:32,210 --> 00:01:33,319 But on the other hand, once I've fixed 47 00:01:33,320 --> 00:01:34,699 it, I get attached to it and I don't want 48 00:01:34,700 --> 00:01:36,859 it to break. So I guess so this fear of 49 00:01:36,860 --> 00:01:38,749 losing it. So, you know, 50 00:01:39,830 --> 00:01:41,899 poverty, dreams and stuff, it 51 00:01:41,900 --> 00:01:43,339 becomes a sort of a mixed blessing. 52 00:01:43,340 --> 00:01:45,109 When you have this, you have stuff and 53 00:01:45,110 --> 00:01:46,219 then you're afraid to lose it. 54 00:01:46,220 --> 00:01:47,509 You know, the song says, when you got 55 00:01:47,510 --> 00:01:49,339 nothing, you got nothing to lose. 56 00:01:49,340 --> 00:01:50,359 It's but it's not really true. 57 00:01:50,360 --> 00:01:51,379 It's when you get nothing. You can't 58 00:01:51,380 --> 00:01:52,759 afford to lose anything. 59 00:01:52,760 --> 00:01:54,619 That's really how I looked, how I've 60 00:01:54,620 --> 00:01:56,059 lived most of my life. 61 00:01:56,060 --> 00:01:57,469 And there's another aspect that I'm very 62 00:01:57,470 --> 00:01:59,299 tenacious, so I have this sort of never 63 00:01:59,300 --> 00:02:01,249 give up attitude. That's also a mixed 64 00:02:01,250 --> 00:02:02,569 blessing and a lot of ways. 65 00:02:04,190 --> 00:02:06,139 And one last thing about me, I usually 66 00:02:06,140 --> 00:02:08,448 like stuff that nobody else likes. 67 00:02:08,449 --> 00:02:10,728 I mean, I'm the only one who buys 68 00:02:10,729 --> 00:02:12,049 the one little thing in the shop that's 69 00:02:12,050 --> 00:02:13,459 been there on the shelf for 100 years, 70 00:02:13,460 --> 00:02:15,049 and nobody wants it because they don't 71 00:02:15,050 --> 00:02:16,219 know what it's for because they just 72 00:02:16,220 --> 00:02:17,220 don't like it. 73 00:02:18,380 --> 00:02:19,380 So 74 00:02:22,910 --> 00:02:24,579 this whole project started. 75 00:02:24,580 --> 00:02:25,489 I come into this work. 76 00:02:25,490 --> 00:02:26,569 I guess not. 77 00:02:26,570 --> 00:02:27,570 And you change slides. 78 00:02:29,290 --> 00:02:30,519 All right.

It's got these things in the 94 00:02:54,490 --> 00:02:56,129 middle here. This is one of my guitars. 95 00:02:56,130 --> 00:02:57,819 It's a guitar that probably no one's ever 96 00:02:57,820 --> 00:02:59,439 seen before. There's only two of them in 97 00:02:59,440 --> 00:03:00,669 Belgium. 98 00:03:00,670 --> 00:03:02,919 It's made in Canada, so you get two 99 00:03:02,920 --> 00:03:04,179 or this one has to pick. 100 00:03:04,180 --> 00:03:05,529 They call them pickups. That's week that 101 00:03:05,530 --> 00:03:07,749 captures the vibrations of the strings, 102 00:03:07,750 --> 00:03:09,429 turn to turn it into an electrical 103 00:03:09,430 --> 00:03:12,309 signal. And then here you have a switch, 104 00:03:12,310 --> 00:03:14,079 which basically which routes the signals 105 00:03:14,080 --> 00:03:16,149 from the pickups to 106 00:03:16,150 --> 00:03:17,859 the volume and tone controls which are 107 00:03:17,860 --> 00:03:19,509 here. And this guitar just has one volume 108 00:03:19,510 --> 00:03:20,529 and one tone. 109 00:03:20,530 --> 00:03:22,659 And then it all goes out through 110 00:03:22,660 --> 00:03:25,689 the jack to the to the amplifier. 111 00:03:25,690 --> 00:03:26,669 It's pretty simple. 112 00:03:26,670 --> 00:03:28,779 I mean, it seems pretty simple, 113 00:03:28,780 --> 00:03:30,459 although it took me a long time to 114 00:03:30,460 --> 00:03:31,460 understand it. 115 00:03:33,070 --> 00:03:34,209 So that's what a guitar is. 116 00:03:34,210 --> 00:03:36,189 Now here's what I know about electronics. 117 00:03:36,190 --> 00:03:37,190 That's it. 118 00:03:42,100 --> 00:03:43,659 You're laughing, you're laughing, you're 119 00:03:43,660 --> 00:03:45,879 laughing, but I didn't find very funny. 120 00:03:45,880 --> 00:03:47,829 I spent a lot of time even that, you 121 00:03:47,830 --> 00:03:49,899 know, it seems so simple and is simple, 122 00:03:49,900 --> 00:03:51,129 but took me a long time to understand 123 00:03:51,130 --> 00:03:52,689 things like a voltage divider. 124 00:03:52,690 --> 00:03:54,669 What is what is that?

Why does it have to have 204 00:06:18,310 --> 00:06:19,599 these mechanical things? 205 00:06:19,600 --> 00:06:21,309 And you know, there's all kinds of stuff, 206 00:06:21,310 --> 00:06:22,539 for example, on out of the guitar I 207 00:06:22,540 --> 00:06:23,589 showed you. 208 00:06:23,590 --> 00:06:24,609 It does some cool stuff. 209 00:06:24,610 --> 00:06:26,139 It's not just an ordinary guitar, it does 210 00:06:26,140 --> 00:06:27,759 some pretty cool stuff. So basically, you 211 00:06:27,760 --> 00:06:29,829 have, you know, the two pickups, you can 212 00:06:29,830 --> 00:06:32,409 have either one or the other or both. 213 00:06:32,410 --> 00:06:35,199 So both in parallel, both in series 214 00:06:35,200 --> 00:06:36,669 series is already in advance. 215 00:06:36,670 --> 00:06:37,719 I mean, this is only something that 216 00:06:37,720 --> 00:06:39,879 became imagined later, much 217 00:06:39,880 --> 00:06:42,009 later. But this guitar has has all of 218 00:06:42,010 --> 00:06:43,479 that, and those are very, very 219 00:06:43,480 --> 00:06:45,489 sophisticated pickups which were only 220 00:06:45,490 --> 00:06:47,689 invented, I guess, 10, 12 years ago. 221 00:06:47,690 --> 00:06:48,729 They're very sophisticated. It's very 222 00:06:48,730 --> 00:06:50,739 sophisticated guitar, but it offers both 223 00:06:51,940 --> 00:06:53,799 the neck. The bridge to the neck is the 224 00:06:53,800 --> 00:06:55,119 top one, the bridge, the bottom one, so 225 00:06:55,120 --> 00:06:56,349 you can have the neck, you can have the 226 00:06:56,350 --> 00:06:57,489 bridge, you can have the neck and the 227 00:06:57,490 --> 00:06:58,839 bridge and series and the neck and bridge 228 00:06:58,840 --> 00:07:00,519 and parallel. So that's that's already 229 00:07:00,520 --> 00:07:02,629 pretty sophisticated for a musician 230 00:07:02,630 --> 00:07:04,089 that's already incomprehensible for most 231 00:07:04,090 --> 00:07:05,719 musicians. My guitar teacher, when I tell 232 00:07:05,720 --> 00:07:06,789 him, What do you mean? 233 00:07:06,790 --> 00:07:07,689 What are you talking about? 234 00:07:07,690 --> 00:07:09,279 So I saying, Well, I was just saying, 235 00:07:09,280 --> 00:07:11,289 it's like jazz and rock. 236 00:07:11,290 --> 00:07:12,459 Oh, I get it. 237 00:07:12,460 --> 00:07:13,419 I get it. I get it. 238 00:07:13,420 --> 00:07:15,549 I get it. So but even 239 00:07:15,550 --> 00:07:16,479 that, so you have to. 240 00:07:16,480 --> 00:07:17,439 So what does that mean? That means that 241 00:07:17,440 --> 00:07:18,979 little switch. There is four positions, 242 00:07:18,980 --> 00:07:21,129 huh? There's three one for each 243 00:07:21,130 --> 00:07:22,539 thing. And if you want to start turning 244 00:07:22,540 --> 00:07:23,469 things on, turning things off, 245 00:07:23,470 --> 00:07:25,059 everything, you need a mechanical switch 246 00:07:25,060 --> 00:07:26,289 and you want to have individual tone 247 00:07:26,290 --> 00:07:27,999 controls, individual volume controls, 248 00:07:28,000 --> 00:07:29,889 everything needs more mechanical stuff. 249 00:07:29,890 --> 00:07:31,239 And pretty soon you have your guitar just 250 00:07:31,240 --> 00:07:33,519 covered with buttons and nobody 251 00:07:33,520 --> 00:07:34,779 knows how it works. You even yourself, 252 00:07:34,780 --> 00:07:35,799 even though you built it yourself, you 253 00:07:35,800 --> 00:07:37,329 still you can't remember which button to 254 00:07:37,330 --> 00:07:39,519 push to get this sound, or today it 255 00:07:39,520 --> 00:07:41,229 becomes just a mess. So I thought my 256 00:07:41,230 --> 00:07:43,329 vision was, let's get rid of all this 257 00:07:43,330 --> 00:07:46,029 electro mechanical crap and put 258 00:07:46,030 --> 00:07:48,159 put a screen on it or make it have a 259 00:07:48,160 --> 00:07:49,719 have a circuit in there and then have a 260 00:07:49,720 --> 00:07:51,999 screen where you can have it synthetic 261 00:07:52,000 --> 00:07:53,739 and you can have do all kinds of stuff. 262 00:07:53,740 --> 00:07:54,759 So. So why not? 263 00:07:54,760 --> 00:07:56,549 Why can't that be? 264 00:07:56,550 --> 00:07:58,809 And OK, we've already seen 265 00:07:58,810 --> 00:08:00,759 that. So that was my vision was to have 266 00:08:00,760 --> 00:08:03,099 some kind of circuit on a on an Android 267 00:08:03,100 --> 00:08:04,659 phone and Bluetooth. 268 00:08:04,660 --> 00:08:06,189 And in there I get in there, you know, 269 00:08:06,190 --> 00:08:07,419 some kind of thing. I don't know what an 270 00:08:07,420 --> 00:08:09,099 Arduino it turned out to be. 271 00:08:09,100 --> 00:08:11,499 That was my idea and don't 272 00:08:11,500 --> 00:08:12,459 seemed easy enough. 273 00:08:12,460 --> 00:08:13,769 Modern technology, you know, stuff 274 00:08:13,770 --> 00:08:15,969 vehicles air as good enough. 275 00:08:15,970 --> 00:08:18,519 And why didn't this already exist? 276 00:08:18,520 --> 00:08:20,739 Well, I have. I had a lot of friends 277 00:08:20,740 --> 00:08:22,809 or friends of friends 278 00:08:22,810 --> 00:08:25,259 in the music industry, and 279 00:08:25,260 --> 00:08:26,829 they all came up with the same answers. 280 00:08:26,830 --> 00:08:27,729 There's two reasons why. 281 00:08:27,730 --> 00:08:29,109 First of all, it's just unbelievably 282 00:08:29,110 --> 00:08:30,219 complicated. You need a team of 283 00:08:30,220 --> 00:08:31,509 engineers, hundreds of years of 284 00:08:31,510 --> 00:08:33,579 development, and 285 00:08:33,580 --> 00:08:35,229 it's just really complicated. 286 00:08:35,230 --> 00:08:36,369 And this was brought from professional, 287 00:08:36,370 --> 00:08:37,899 from engineers in the music industry. 288 00:08:37,900 --> 00:08:39,908 This is not just from musicians. 289 00:08:39,909 --> 00:08:41,029 And then the other thing was. 290 00:08:41,030 --> 00:08:42,019 Nobody wants it. 291 00:08:42,020 --> 00:08:43,609 It's just ridiculous, everybody. 292 00:08:43,610 --> 00:08:45,889 Everybody wants to have a knob and 293 00:08:45,890 --> 00:08:47,359 a switch. That's what musicians want. 294 00:08:47,360 --> 00:08:48,589 That's it. That's it. 295 00:08:48,590 --> 00:08:49,909 That's all there is. So just don't waste 296 00:08:49,910 --> 00:08:51,319 your time. 297 00:08:51,320 --> 00:08:53,959 And so that's 298 00:08:53,960 --> 00:08:55,519 yeah, I didn't really waste a lot of my 299 00:08:55,520 --> 00:08:56,839 time, but I kept thinking about it. 300 00:08:56,840 --> 00:08:58,159 I kept thinking about it. 301 00:08:58,160 --> 00:08:59,359 And since I didn't know anything about 302 00:08:59,360 --> 00:09:01,399 electronics, it was kind of a handicap. 303 00:09:01,400 --> 00:09:03,139 It was kind of, you know, what to do 304 00:09:03,140 --> 00:09:06,109 about this and how to make progress. 305 00:09:06,110 --> 00:09:07,919 So it's so this idea of just being around 306 00:09:07,920 --> 00:09:10,609 in my head for a while and then 307 00:09:10,610 --> 00:09:12,109 nothing happened. Then I I used to go to 308 00:09:12,110 --> 00:09:13,729 a lot of Ted guys to do the TED 309 00:09:13,730 --> 00:09:14,809 conferences in Brussels. 310 00:09:14,810 --> 00:09:16,579 I live in Brussels and we have the Ted X 311 00:09:16,580 --> 00:09:19,189 there, and you get a lot of inspirational 312 00:09:19,190 --> 00:09:20,959 guys talking and we've been talking about 313 00:09:20,960 --> 00:09:22,099 stuff they've done. 314 00:09:22,100 --> 00:09:23,100 And. 315 00:09:25,540 --> 00:09:27,719 And I went to one of these and 316 00:09:27,720 --> 00:09:28,899 had a good time with it, and 317 00:09:30,110 --> 00:09:31,390 I was thinking, you know, 318 00:09:32,650 --> 00:09:34,569 is it really impossible to make this or 319 00:09:34,570 --> 00:09:36,669 is it just people that are scared of it? 320 00:09:36,670 --> 00:09:38,829 And it made me think 321 00:09:38,830 --> 00:09:40,689 about Marshall McLuhan. 322 00:09:40,690 --> 00:09:41,949 Does anybody know here? 323 00:09:41,950 --> 00:09:43,689 Know who Marshall McLuhan is? 324 00:09:43,690 --> 00:09:44,799 One person? 325 00:09:44,800 --> 00:09:46,720 That's it.

So he invented the phrase the 339 00:10:14,650 --> 00:10:16,179 global village. But he wasn't thinking 340 00:10:16,180 --> 00:10:17,829 about computers. He was thinking about 341 00:10:17,830 --> 00:10:19,569 the electrical network that ran 342 00:10:19,570 --> 00:10:20,499 throughout the world. 343 00:10:20,500 --> 00:10:21,659 And he thought that was cool.

Find all these 410 00:12:10,460 --> 00:12:11,569 experts told me. Forget it. 411 00:12:11,570 --> 00:12:12,570 Forget it. Forget it. 412 00:12:18,170 --> 00:12:20,059 And so, yeah, it's it's a shame he's not 413 00:12:20,060 --> 00:12:22,509 in the room, but he gets a slide, 414 00:12:22,510 --> 00:12:24,649 so. So that's, you know, he 415 00:12:24,650 --> 00:12:25,939 hooked me, he said, contact the 416 00:12:25,940 --> 00:12:27,589 hackerspace community admin or there was 417 00:12:27,590 --> 00:12:30,019 one in Brussels. I mean, Brussels, 418 00:12:30,020 --> 00:12:31,669 anyway, there's a huge hackerspace 419 00:12:31,670 --> 00:12:33,829 community in Belgium and Brussels, and 420 00:12:33,830 --> 00:12:36,649 I was amazed about 421 00:12:36,650 --> 00:12:37,999 about this. 422 00:12:38,000 --> 00:12:40,069 And so so that was that's the the 423 00:12:40,070 --> 00:12:41,779 middle, the middle part of the project. 424 00:12:41,780 --> 00:12:42,780 Thank you. 425 00:12:43,460 --> 00:12:45,259 And now we can talk about the technology 426 00:12:45,260 --> 00:12:46,999 and stuff, which is maybe interesting. 427 00:12:47,000 --> 00:12:48,000 Maybe not. 428 00:12:51,340 --> 00:12:53,679 So, so that's a potentially 429 00:12:53,680 --> 00:12:55,209 ometer, right? 430 00:12:55,210 --> 00:12:56,499 Most people know what it is. 431 00:12:56,500 --> 00:12:58,749 You got the thing you turn and it and 432 00:12:58,750 --> 00:13:00,669 it moves the way both the W and moves 433 00:13:00,670 --> 00:13:01,749 that up or down. 434 00:13:01,750 --> 00:13:03,609 And that means that one resistance gets 435 00:13:03,610 --> 00:13:05,199 bigger. One gets smaller, right? 436 00:13:05,200 --> 00:13:07,029 It's really it's really it's pretty 437 00:13:07,030 --> 00:13:09,129 simple. So, you know, 438 00:13:09,130 --> 00:13:10,689 and through them, are we having an analog 439 00:13:10,690 --> 00:13:12,039 signal coming from the air? 440 00:13:12,040 --> 00:13:14,709 So it's a sign of it coming from the 441 00:13:14,710 --> 00:13:15,999 from the pickups. 442 00:13:16,000 --> 00:13:18,399 So the question was how how 443 00:13:18,400 --> 00:13:21,159 could I? Could you make that controllable 444 00:13:21,160 --> 00:13:22,479 digitally somehow? 445 00:13:22,480 --> 00:13:24,609 I mean, I thought about putting servos 446 00:13:24,610 --> 00:13:26,859 on their motors and all kinds 447 00:13:26,860 --> 00:13:28,059 of stupid things. It was really. 448 00:13:28,060 --> 00:13:29,679 And a lot of stupid ideas. 449 00:13:29,680 --> 00:13:31,179 But I put this out on the hackerspace 450 00:13:31,180 --> 00:13:32,889 mailing list and people had all kinds of 451 00:13:32,890 --> 00:13:34,299 answers, but they all it all seemed to be 452 00:13:34,300 --> 00:13:36,069 like they were. It wasn't criticism, but 453 00:13:36,070 --> 00:13:37,509 they didn't know what I wanted, and I 454 00:13:37,510 --> 00:13:39,219 felt like there was really some kind of 455 00:13:39,220 --> 00:13:40,869 really cool hand, Luke. 456 00:13:40,870 --> 00:13:42,999 What we got here is failure to 457 00:13:43,000 --> 00:13:44,589 communicate, and then they whack him over 458 00:13:44,590 --> 00:13:45,489 the head. 459 00:13:45,490 --> 00:13:47,349 You know, the great movie Paul Newman's 460 00:13:47,350 --> 00:13:49,299 masterpiece, anyway, was a failure to 461 00:13:49,300 --> 00:13:50,739 communicate, and that was something I 462 00:13:50,740 --> 00:13:52,299 learned a lot in this project is you ask 463 00:13:52,300 --> 00:13:53,889 questions and they make perfect sense to 464 00:13:53,890 --> 00:13:55,959 you, but nobody else can understand 465 00:13:55,960 --> 00:13:57,669 what you're talking about. 466 00:13:57,670 --> 00:13:59,109 You know, you ask a question of for me 467 00:13:59,110 --> 00:14:00,699 said, I got this thing in this thing and 468 00:14:00,700 --> 00:14:01,899 this thing, people and people don't 469 00:14:01,900 --> 00:14:04,479 answer or they ask the with 470 00:14:04,480 --> 00:14:05,599 crazy things. 471 00:14:05,600 --> 00:14:06,489 Then you realize that they don't 472 00:14:06,490 --> 00:14:09,549 understand and they didn't understand. 473 00:14:09,550 --> 00:14:11,649 So finally, though, after a lot of 474 00:14:11,650 --> 00:14:13,179 questions being tenacious, remember 475 00:14:13,180 --> 00:14:14,139 tenacity. 476 00:14:14,140 --> 00:14:16,659 We got to we got to an answer by Yohannes 477 00:14:16,660 --> 00:14:19,239 Talman, who is a brilliant scientist. 478 00:14:19,240 --> 00:14:20,559 He's not here, either. 479 00:14:20,560 --> 00:14:22,209 Well, he's got he's he's in the hacker in 480 00:14:22,210 --> 00:14:24,129 there in cyberspace, and he's just he 481 00:14:24,130 --> 00:14:25,809 said, Well, why don't you do with a lead, 482 00:14:25,810 --> 00:14:26,810 LDR? 483 00:14:27,620 --> 00:14:29,019 And you know, I didn't I didn't know if 484 00:14:29,020 --> 00:14:31,689 that was a word or if that was acronyms 485 00:14:31,690 --> 00:14:33,189 like. OK, great. 486 00:14:33,190 --> 00:14:35,049 Now tell me more about what that is. 487 00:14:35,050 --> 00:14:37,149 So actually, I led 488 00:14:37,150 --> 00:14:39,489 LDR is really a lead, you know, a light 489 00:14:39,490 --> 00:14:41,919 and and a light dependent resistor. 490 00:14:41,920 --> 00:14:43,839 So you have something to shine a light. 491 00:14:43,840 --> 00:14:45,009 And then you have something which changes 492 00:14:45,010 --> 00:14:46,959 resistance when you shine light on it. 493 00:14:46,960 --> 00:14:49,299 OK. And you put those two together 494 00:14:49,300 --> 00:14:51,369 and once so that that makes 495 00:14:51,370 --> 00:14:54,099 a digitally controlled resistance 496 00:14:54,100 --> 00:14:56,049 because you can shine light more or less, 497 00:14:56,050 --> 00:14:57,789 you can pulse it with P.W. 498 00:14:57,790 --> 00:15:00,069 and then you. So now you have a digitally 499 00:15:00,070 --> 00:15:01,299 controlled burn resistance. 500 00:15:01,300 --> 00:15:02,469 And if you put two of them together, like 501 00:15:02,470 --> 00:15:04,479 in that picture, you get something very 502 00:15:04,480 --> 00:15:06,759 similar to a potentially amateur. 503 00:15:06,760 --> 00:15:08,079 And all you have to do is manage the 504 00:15:08,080 --> 00:15:09,909 current. And in the meantime, you know, 505 00:15:09,910 --> 00:15:11,589 I've been playing with I got getting 506 00:15:11,590 --> 00:15:12,669 started with Arduino. 507 00:15:12,670 --> 00:15:14,769 I saw Bansi on on Ted and I 508 00:15:14,770 --> 00:15:16,479 got the book and I got an Adreno and I 509 00:15:16,480 --> 00:15:18,849 could make the lamp, the LEDs blink. 510 00:15:18,850 --> 00:15:20,499 And yeah, it was great. 511 00:15:20,500 --> 00:15:21,849 Everything was great. The whole problems 512 00:15:21,850 --> 00:15:22,779 were soft. 513 00:15:22,780 --> 00:15:23,829 You see, it seems so simple. 514 00:15:23,830 --> 00:15:26,049 It's like, why didn't you know 515 00:15:26,050 --> 00:15:28,299 what's wrong with people? Like, why? 516 00:15:28,300 --> 00:15:29,349 Well, it's so easy. 517 00:15:29,350 --> 00:15:30,639 It's just so unbelievably easy. 518 00:15:30,640 --> 00:15:31,959 So I started doing it. 519 00:15:31,960 --> 00:15:33,519 But somebody on the mailing list said, 520 00:15:33,520 --> 00:15:35,799 you know, he said this, he said, I quote 521 00:15:35,800 --> 00:15:37,809 this you certainly work to some extent. 522 00:15:37,810 --> 00:15:39,759 And even if the result is too noisy or 523 00:15:39,760 --> 00:15:41,829 bad quality to be used in music, it 524 00:15:41,830 --> 00:15:43,749 will be it will still be huge fun to 525 00:15:43,750 --> 00:15:45,639 make. And I said I thought to myself, 526 00:15:45,640 --> 00:15:48,009 What noisy, noisy whip. 527 00:15:48,010 --> 00:15:49,839 But where's noise coming from? 528 00:15:49,840 --> 00:15:52,089 How can vehicles and where 529 00:15:52,090 --> 00:15:53,199 is noise in that equation? 530 00:15:53,200 --> 00:15:54,579 I don't get it. 531 00:15:54,580 --> 00:15:56,079 But that was kind of it's kind of stayed 532 00:15:56,080 --> 00:15:57,399 in the back of my mind is something 533 00:15:57,400 --> 00:15:58,599 about, you know, who cares? 534 00:15:58,600 --> 00:16:00,849 Went on, by the way, 535 00:16:00,850 --> 00:16:02,919 led elders actually in the 536 00:16:02,920 --> 00:16:04,479 industry. They're called vectors. 537 00:16:04,480 --> 00:16:06,249 There's an a component which has the 538 00:16:06,250 --> 00:16:07,869 whole thing built in one, and they're 539 00:16:07,870 --> 00:16:08,799 made by different companies. 540 00:16:08,800 --> 00:16:11,799 The best company is PerkinElmer. 541 00:16:11,800 --> 00:16:13,419 If you if you buy them, just put my name 542 00:16:13,420 --> 00:16:14,829 in the end. So I get my commission. 543 00:16:14,830 --> 00:16:15,950 OK? All right. 544 00:16:17,560 --> 00:16:19,059 All right. So so that was easy. 545 00:16:19,060 --> 00:16:20,979 So now I had the the fundamental problem 546 00:16:20,980 --> 00:16:22,569 solved, and now I just had to learn how 547 00:16:22,570 --> 00:16:24,789 to do it. So I read Making 548 00:16:24,790 --> 00:16:26,889 Things Talk, Buy time ago 549 00:16:26,890 --> 00:16:28,779 and later corresponded with and found out 550 00:16:28,780 --> 00:16:30,159 that he didn't test all the code in his 551 00:16:30,160 --> 00:16:31,160 book. 552 00:16:33,090 --> 00:16:35,249 So here it is, so so the idea was 553 00:16:35,250 --> 00:16:37,259 really you have you have you have a 554 00:16:37,260 --> 00:16:39,209 guitar and Arduino in there, a bunch of 555 00:16:39,210 --> 00:16:41,489 tools and then you have some kind 556 00:16:41,490 --> 00:16:43,109 of Bluetooth and you have some kind of 557 00:16:43,110 --> 00:16:45,089 device, a computer, android. 558 00:16:45,090 --> 00:16:46,439 I'd never seen an Android phone in my 559 00:16:46,440 --> 00:16:48,479 life at the time, but I figured that 560 00:16:48,480 --> 00:16:50,130 would do it and it would be really easy. 561 00:16:52,050 --> 00:16:53,159 Yeah, and it was. 562 00:16:54,240 --> 00:16:56,399 So here's here's here's the really good 563 00:16:56,400 --> 00:16:57,479 the geeky part, huh? 564 00:16:57,480 --> 00:16:58,989 This is the real. This is the schematic. 565 00:16:58,990 --> 00:17:00,929 I I only made it because the person 566 00:17:00,930 --> 00:17:03,179 revising my presentation here told me 567 00:17:03,180 --> 00:17:04,769 to make it more technical because it's a 568 00:17:04,770 --> 00:17:06,328 technical conference. 569 00:17:06,329 --> 00:17:07,679 All right. So here's the technical stuff. 570 00:17:07,680 --> 00:17:08,680 You wanted to get it. 571 00:17:10,859 --> 00:17:13,019 Where are you going, OK, in the upper 572 00:17:13,020 --> 00:17:14,669 left there, you can barely see it, but 573 00:17:14,670 --> 00:17:16,469 you have the the gate, so there's three. 574 00:17:16,470 --> 00:17:17,368 I put three pickups. 575 00:17:17,369 --> 00:17:19,019 This guitar has three pickups. 576 00:17:19,020 --> 00:17:20,789 And you see this one has one sort of 577 00:17:20,790 --> 00:17:22,739 double pick up, which is exactly what it 578 00:17:22,740 --> 00:17:24,689 is. So the three pickups, they come in, 579 00:17:24,690 --> 00:17:25,979 so the top one goes in and you have the 580 00:17:25,980 --> 00:17:28,139 red wire goes to a vacuole, which 581 00:17:28,140 --> 00:17:29,579 is just an on and off that drill. 582 00:17:29,580 --> 00:17:31,649 So it's it's got no, it's got 583 00:17:31,650 --> 00:17:33,959 no variable resistance, just shine 584 00:17:33,960 --> 00:17:36,209 all maximum light and it lets maximum 585 00:17:36,210 --> 00:17:38,039 maximum electricity through. 586 00:17:38,040 --> 00:17:39,059 It's not perfect. 587 00:17:39,060 --> 00:17:40,769 The fact was I, you have about 80 ohm 588 00:17:40,770 --> 00:17:41,939 resistance when they're meant, when 589 00:17:41,940 --> 00:17:42,869 they're full on. 590 00:17:42,870 --> 00:17:44,039 But you can you can do a little better 591 00:17:44,040 --> 00:17:45,239 than that. 592 00:17:45,240 --> 00:17:46,559 What? I didn't buy the right factors. 593 00:17:46,560 --> 00:17:47,849 I couldn't understand how to read data 594 00:17:47,850 --> 00:17:49,079 sheets. They're so complicated. 595 00:17:49,080 --> 00:17:50,249 Why don't they just say what the what I 596 00:17:50,250 --> 00:17:51,869 want anyways? 597 00:17:51,870 --> 00:17:52,819 So there you have it. 598 00:17:52,820 --> 00:17:54,689 You have each of the each of the pickups 599 00:17:54,690 --> 00:17:56,579 goes into a back to the top for the 600 00:17:56,580 --> 00:17:59,129 switching vector. So you have one per 601 00:17:59,130 --> 00:18:00,629 pick up, except for the last pick up, 602 00:18:00,630 --> 00:18:03,119 which is two pickups, actually two coils. 603 00:18:03,120 --> 00:18:05,339 So, so that means you have to 604 00:18:05,340 --> 00:18:07,439 be able to have both coils on or in 605 00:18:07,440 --> 00:18:09,239 my case, I decided to have both coils in 606 00:18:09,240 --> 00:18:11,399 series or only the only 607 00:18:11,400 --> 00:18:12,359 the top coil. 608 00:18:12,360 --> 00:18:13,979 That's a typical configuration for 609 00:18:13,980 --> 00:18:16,289 guitars. It's called splitting a double 610 00:18:16,290 --> 00:18:18,299 coil, so there's a vector which does the 611 00:18:18,300 --> 00:18:20,819 split. Then you have the orange, 612 00:18:20,820 --> 00:18:22,919 the orange say 613 00:18:22,920 --> 00:18:25,649 input bus, which goes to the vectors 614 00:18:25,650 --> 00:18:28,049 which pretend to be a potential. 615 00:18:28,050 --> 00:18:30,119 Another one pretends to be 616 00:18:30,120 --> 00:18:31,539 the tone control, which is just half a 617 00:18:31,540 --> 00:18:33,149 potentielle motor and a capacity to 618 00:18:33,150 --> 00:18:34,049 ground. 619 00:18:34,050 --> 00:18:35,879 And then the last one was a trick. 620 00:18:35,880 --> 00:18:38,639 I just I thought of to be able to 621 00:18:38,640 --> 00:18:40,829 have maximum volume because the other 622 00:18:40,830 --> 00:18:42,449 ones were all being controlled by P.W. 623 00:18:42,450 --> 00:18:44,249 and pulsed with modulation. 624 00:18:44,250 --> 00:18:46,229 So I could never get the full light with 625 00:18:46,230 --> 00:18:47,559 that. So I just had another one that 626 00:18:47,560 --> 00:18:49,169 could shunt them all out and get full 627 00:18:49,170 --> 00:18:50,189 volume. 628 00:18:50,190 --> 00:18:52,079 And then it goes to the jack out. 629 00:18:52,080 --> 00:18:53,579 And you see, one of the great things 630 00:18:53,580 --> 00:18:55,769 about vectors is this whole circuit that 631 00:18:55,770 --> 00:18:56,849 is optically isolate. 632 00:18:56,850 --> 00:18:58,919 So this part is is not in any 633 00:18:58,920 --> 00:19:00,689 electrical communication with that part, 634 00:19:00,690 --> 00:19:02,309 and the ground is provided by the 635 00:19:02,310 --> 00:19:03,599 amplifier. 636 00:19:03,600 --> 00:19:05,219 So it's completely separate from the 637 00:19:05,220 --> 00:19:06,220 Arduino ground, 638 00:19:07,660 --> 00:19:09,150 something I had to learn the hard way. 639 00:19:11,490 --> 00:19:13,049 And then you have the resistances on the 640 00:19:13,050 --> 00:19:15,149 bottom there, which do the which control 641 00:19:15,150 --> 00:19:17,189 the the the current to the LEDs. 642 00:19:17,190 --> 00:19:18,959 And something I don't understand is I 643 00:19:18,960 --> 00:19:20,609 ended up just empirically testing all 644 00:19:20,610 --> 00:19:21,959 different types of resistance to get the 645 00:19:21,960 --> 00:19:22,859 amount of light I needed. 646 00:19:22,860 --> 00:19:24,929 And I ended up with microscopic 647 00:19:24,930 --> 00:19:27,249 current to the vectors, which was not on 648 00:19:27,250 --> 00:19:28,349 the data sheets at all. 649 00:19:28,350 --> 00:19:30,209 It says I don't know how it works, but it 650 00:19:30,210 --> 00:19:31,619 does pretty well. 651 00:19:31,620 --> 00:19:32,969 And then you have the Bluetooth, a 652 00:19:32,970 --> 00:19:35,189 Bluetooth radio. 653 00:19:35,190 --> 00:19:37,229 I ended up using a Spark phone radio at 654 00:19:37,230 --> 00:19:38,129 the time is running out. 655 00:19:38,130 --> 00:19:39,479 I'm sorry, you're going to have to just 656 00:19:39,480 --> 00:19:41,399 skip over all this stuff. 657 00:19:41,400 --> 00:19:43,529 And then I wrote, So so I bought this 658 00:19:43,530 --> 00:19:45,749 old guitars in old 1980 RG 659 00:19:45,750 --> 00:19:47,190 140 from even years, 660 00:19:48,840 --> 00:19:50,909 and they didn't give me permission to to 661 00:19:50,910 --> 00:19:52,709 use pictures in the in the in the show, 662 00:19:52,710 --> 00:19:54,419 but they can't prevent me from holding it 663 00:19:54,420 --> 00:19:56,669 here. So anyway, and I used a very, 664 00:19:56,670 --> 00:19:59,639 very inexpensive G-A-Y MCU 665 00:19:59,640 --> 00:20:01,799 Bluetooth radio module to connect 666 00:20:01,800 --> 00:20:04,519 to the two to think five euros. 667 00:20:04,520 --> 00:20:06,269 I couldn't understand why it was why I 668 00:20:06,270 --> 00:20:07,409 didn't work very well. 669 00:20:07,410 --> 00:20:09,089 I mean, five euros come on. 670 00:20:09,090 --> 00:20:10,199 It's a lot of money. 671 00:20:10,200 --> 00:20:12,269 But I ended up having a lot of a 672 00:20:12,270 --> 00:20:14,579 lot of problems with that with 673 00:20:14,580 --> 00:20:16,559 you, with noise, actually. 674 00:20:16,560 --> 00:20:18,059 But let me tell you before I talk about 675 00:20:18,060 --> 00:20:20,279 the problems, when I when I plugged it in 676 00:20:20,280 --> 00:20:21,779 the first time and I built the circuit 677 00:20:21,780 --> 00:20:23,789 and started it all with prototype for two 678 00:20:23,790 --> 00:20:25,859 hours, even days, I made some 679 00:20:25,860 --> 00:20:28,289 mistakes and so I put it in, plug it in, 680 00:20:28,290 --> 00:20:30,029 turn it on and it worked. 681 00:20:30,030 --> 00:20:31,049 And it all worked. 682 00:20:31,050 --> 00:20:32,369 The first time I felt like Dr. 683 00:20:32,370 --> 00:20:33,689 Frankenstein. You know, when the 684 00:20:33,690 --> 00:20:35,519 Lightning, when the lightning hits the I 685 00:20:35,520 --> 00:20:37,749 think in the end, the monster wakes up. 686 00:20:37,750 --> 00:20:39,119 I tell exactly how I felt. 687 00:20:39,120 --> 00:20:40,229 It was just great. 688 00:20:40,230 --> 00:20:41,909 That's why it was the high point of last 689 00:20:41,910 --> 00:20:42,910 year, I tell you. 690 00:20:44,580 --> 00:20:46,859 And so I mean, that's 691 00:20:46,860 --> 00:20:47,860 all the good news. 692 00:20:48,750 --> 00:20:50,159 I'm not going to talk about the software 693 00:20:50,160 --> 00:20:51,689 development. That's kind of just software 694 00:20:51,690 --> 00:20:53,579 development. I wrote a first I wrote a 695 00:20:53,580 --> 00:20:55,799 green in parricide 696 00:20:55,800 --> 00:20:57,929 Python plus for the for my 697 00:20:57,930 --> 00:20:59,339 laptop. 698 00:20:59,340 --> 00:21:00,839 That's that worked really well. 699 00:21:00,840 --> 00:21:02,219 That worried me because I knew when, you 700 00:21:02,220 --> 00:21:03,329 know, when the prototypes work that 701 00:21:03,330 --> 00:21:05,400 you're in trouble for the final version 702 00:21:06,540 --> 00:21:08,819 and you know, 703 00:21:08,820 --> 00:21:11,279 and then then I thought about Bluetooth, 704 00:21:11,280 --> 00:21:13,349 I read an Argos book about how to 705 00:21:13,350 --> 00:21:15,629 do it. I copied his code and work. 706 00:21:15,630 --> 00:21:17,009 I wrote to him. He said, Yeah, well, I 707 00:21:17,010 --> 00:21:18,779 never tested it. Sorry. 708 00:21:18,780 --> 00:21:20,849 OK. And then I managed to get it to 709 00:21:20,850 --> 00:21:23,009 work. And then I had to port it to to 710 00:21:23,010 --> 00:21:25,109 Android. And I found out that Python on 711 00:21:25,110 --> 00:21:27,179 Android is sort of like, you know, 712 00:21:27,180 --> 00:21:29,279 especially parricide on Android is, you 713 00:21:29,280 --> 00:21:30,869 know, like, no, no, no, no. 714 00:21:30,870 --> 00:21:32,459 So forgot about that. 715 00:21:32,460 --> 00:21:34,019 And I thought, OK, I'm going to learn the 716 00:21:34,020 --> 00:21:36,419 Java framework and a lifetime 717 00:21:36,420 --> 00:21:37,470 of learning. Forget it. 718 00:21:39,150 --> 00:21:41,309 And I found that processing could be 719 00:21:41,310 --> 00:21:43,469 compiled by compiled for Android 720 00:21:43,470 --> 00:21:45,779 and do so. It just covers 721 00:21:45,780 --> 00:21:47,909 encapsulate all the Android Java 722 00:21:47,910 --> 00:21:50,039 framework in pain processing and 723 00:21:50,040 --> 00:21:52,260 that was easily done, except 724 00:21:53,310 --> 00:21:55,139 that the Bluetooth Library for Processing 725 00:21:55,140 --> 00:21:57,359 Kit Library had a good amount of 726 00:21:57,360 --> 00:21:58,499 bugs in it. 727 00:21:58,500 --> 00:22:00,389 I wrote to those guys and they, you know, 728 00:22:00,390 --> 00:22:02,160 they had that ended up. 729 00:22:03,240 --> 00:22:04,769 So for example, there's a function called 730 00:22:04,770 --> 00:22:07,169 connected. It always returns false. 731 00:22:08,740 --> 00:22:09,740 Are you connected? No, 732 00:22:12,060 --> 00:22:13,749 but but the signals are coming back and 733 00:22:13,750 --> 00:22:14,799 forth that we're not connected. 734 00:22:16,690 --> 00:22:18,309 That's a good one, but so you couldn't 735 00:22:18,310 --> 00:22:20,829 use that anyways. 736 00:22:20,830 --> 00:22:23,229 So I mean, that's that was the next slide 737 00:22:23,230 --> 00:22:24,279 and we've already seen it. 738 00:22:24,280 --> 00:22:25,479 So you have on the one hand, you have 739 00:22:25,480 --> 00:22:27,039 processing Android and Bluetooth. 740 00:22:27,040 --> 00:22:29,169 The other side you have vectors, you 741 00:22:29,170 --> 00:22:31,329 know, C++ and 742 00:22:31,330 --> 00:22:32,949 an a Bluetooth module. 743 00:22:32,950 --> 00:22:34,599 And maybe I'll skip ahead a huge amount 744 00:22:34,600 --> 00:22:36,759 of problem with noise, but it's it's 745 00:22:36,760 --> 00:22:38,979 worth.

There's no whistling and 811 00:24:50,020 --> 00:24:51,009 there's no whistling. 812 00:24:51,010 --> 00:24:53,109 But there was whistling and it was and it 813 00:24:53,110 --> 00:24:54,249 was during communications. 814 00:24:54,250 --> 00:24:55,329 So when you sent it, when I typed 815 00:24:55,330 --> 00:24:56,949 something on the keyboard here on the on 816 00:24:56,950 --> 00:24:58,179 the Versa, then you can you could hear 817 00:24:58,180 --> 00:24:59,169 the whistling through the AMP. 818 00:24:59,170 --> 00:25:00,759 And it was it was really annoying and it 819 00:25:00,760 --> 00:25:03,279 would last exactly ten seconds after 820 00:25:03,280 --> 00:25:04,989 the end of communication. 821 00:25:04,990 --> 00:25:06,639 So this was really annoying and really 822 00:25:06,640 --> 00:25:08,409 painful. And so I had all these forum 823 00:25:08,410 --> 00:25:10,119 discussions, especially the best form was 824 00:25:10,120 --> 00:25:11,949 the Android Electronics General 825 00:25:11,950 --> 00:25:13,189 Electronics Forum. 826 00:25:13,190 --> 00:25:15,399 It was my my my thread was the top 827 00:25:15,400 --> 00:25:17,529 of the list for months. 828 00:25:17,530 --> 00:25:18,969 Literally, that was I must have must have 829 00:25:18,970 --> 00:25:21,339 been 100 or 200 responses in people. 830 00:25:21,340 --> 00:25:22,959 And there was some guy who spent all of 831 00:25:22,960 --> 00:25:25,029 his waking hours trying to figure it out, 832 00:25:25,030 --> 00:25:26,409 but he couldn't. No one could. 833 00:25:26,410 --> 00:25:27,430 I could. And it just. 834 00:25:28,750 --> 00:25:30,809 And finally, I had this idea that 835 00:25:30,810 --> 00:25:32,259 this seems to be coming from a Bluetooth. 836 00:25:32,260 --> 00:25:34,089 Why not contact the Bluetooth people, 837 00:25:34,090 --> 00:25:35,799 Bluetooth manufacturers? 838 00:25:35,800 --> 00:25:36,759 So I didn't know any. 839 00:25:36,760 --> 00:25:39,369 So I saw a Spark phone had a Bluetooth 840 00:25:39,370 --> 00:25:41,199 module, which costs, you know, upwards of 841 00:25:41,200 --> 00:25:42,219 30 euros. 842 00:25:42,220 --> 00:25:43,419 It's a lot of money. 843 00:25:43,420 --> 00:25:45,079 So I wrote to them saying, How am I going 844 00:25:45,080 --> 00:25:46,749 if I buy this?

So anyway, I wrote to Robin 863 00:26:19,180 --> 00:26:20,289 Networks and told him the story. 864 00:26:20,290 --> 00:26:22,509 You know, the guy MCU isn't so 865 00:26:22,510 --> 00:26:24,129 big. Guy said, Yeah, I've investigated 866 00:26:24,130 --> 00:26:25,809 you, MCU. I've been looking at the specs, 867 00:26:25,810 --> 00:26:26,799 you know, and it's just like this, like 868 00:26:26,800 --> 00:26:27,759 this and like this, like this. 869 00:26:27,760 --> 00:26:29,529 And and it's got all these problems in it 870 00:26:29,530 --> 00:26:30,819 because it's not this. It's not that. 871 00:26:30,820 --> 00:26:32,109 But our chip is like, this is like this, 872 00:26:32,110 --> 00:26:33,039 and it should be a lot better. 873 00:26:33,040 --> 00:26:34,539 But of course, who knows. 874 00:26:34,540 --> 00:26:35,499 So I bought their chip. 875 00:26:35,500 --> 00:26:37,689 I invested 30 euros after great 876 00:26:37,690 --> 00:26:38,859 hesitation. 877 00:26:38,860 --> 00:26:40,929 And I know, I know, but this is the 878 00:26:40,930 --> 00:26:41,930 end of the story 879 00:26:43,180 --> 00:26:45,010 and I plugged it in and it was 880 00:26:46,150 --> 00:26:47,150 almost perfect, 881 00:26:48,250 --> 00:26:50,499 almost really close to perfect. 882 00:26:50,500 --> 00:26:52,719 Most of the noise was gone, but 883 00:26:52,720 --> 00:26:54,729 a little bit still, I thought 884 00:26:54,730 --> 00:26:56,139 electromagnetic interference. 885 00:26:56,140 --> 00:26:57,609 I finally learned that I saw and I saw 886 00:26:57,610 --> 00:26:59,739 that somehow I came across that 887 00:26:59,740 --> 00:27:01,839 EMI. I thought it was a record company, 888 00:27:01,840 --> 00:27:03,069 but no, it's electromagnetic 889 00:27:03,070 --> 00:27:04,299 interference. 890 00:27:04,300 --> 00:27:05,739 My girlfriend used to work my ex, my 891 00:27:05,740 --> 00:27:07,389 previous anyway, someone I used to work 892 00:27:07,390 --> 00:27:09,379 with anyway. 893 00:27:09,380 --> 00:27:11,259 EMI electromagnetic interference. 894 00:27:11,260 --> 00:27:12,549 That's the problem. So how do you figure 895 00:27:12,550 --> 00:27:13,629 out how do you how do you solve that 896 00:27:13,630 --> 00:27:15,519 problem? Who knows. 897 00:27:15,520 --> 00:27:16,989 It's just impossible to solve. 898 00:27:16,990 --> 00:27:18,609 So I contacted shielding companies and 899 00:27:18,610 --> 00:27:19,959 they told me all this stuff, and I just 900 00:27:19,960 --> 00:27:22,119 couldn't understand way too complicated. 901 00:27:22,120 --> 00:27:24,219 But automation was the last 902 00:27:24,220 --> 00:27:25,929 part of the musicians. 903 00:27:25,930 --> 00:27:26,829 You can't you won't be able to see it. 904 00:27:26,830 --> 00:27:29,289 I don't think because the response 905 00:27:29,290 --> 00:27:31,239 rate is not fast enough, but you can hear 906 00:27:31,240 --> 00:27:32,240 it. 907 00:27:33,660 --> 00:27:35,939 So now there's no effects pedal, 908 00:27:35,940 --> 00:27:37,140 I'm now creating a. 909 00:27:38,720 --> 00:27:41,359 A tremolo, just 910 00:27:41,360 --> 00:27:43,639 just by changing the volume rapidly and 911 00:27:43,640 --> 00:27:44,640 the volume and tone. 912 00:27:46,370 --> 00:27:48,019 So that was one of the if that was so 913 00:27:48,020 --> 00:27:49,849 automation I have this can do unlimited 914 00:27:49,850 --> 00:27:50,749 forms of automation. 915 00:27:50,750 --> 00:27:52,609 You just have to just have to read a 916 00:27:52,610 --> 00:27:55,039 little a few lines of text file 917 00:27:55,040 --> 00:27:56,749 and it will automate. 918 00:27:56,750 --> 00:27:58,099 But that allowed me to automate the 919 00:27:58,100 --> 00:27:59,359 communications and I could look more 920 00:27:59,360 --> 00:28:00,709 carefully at the problems. 921 00:28:00,710 --> 00:28:02,659 And by miracle, I discovered that I 922 00:28:02,660 --> 00:28:03,939 could. I could. I have. 923 00:28:03,940 --> 00:28:05,179 I got the stethoscope. 924 00:28:05,180 --> 00:28:07,099 I call you just take a cable, a guitar 925 00:28:07,100 --> 00:28:09,139 cable.

You could. I can. 944 00:28:39,710 --> 00:28:41,279 I can imagine now the Spirit Square, 945 00:28:41,280 --> 00:28:42,349 which is going back and forth, back and 946 00:28:42,350 --> 00:28:44,089 forth and coming out of my hand. 947 00:28:44,090 --> 00:28:45,090 That was the problem. 948 00:28:46,010 --> 00:28:48,439 And so I put lots of shielding 949 00:28:48,440 --> 00:28:50,359 on those wires and it all went away. 950 00:28:50,360 --> 00:28:52,069 And now we have now we have something 951 00:28:52,070 --> 00:28:53,900 that works, and 952 00:28:55,460 --> 00:28:57,379 she's trying to chase me off the stage 953 00:28:57,380 --> 00:28:58,399 here. 954 00:28:58,400 --> 00:29:00,949 And so I can just show you, maybe 955 00:29:00,950 --> 00:29:03,019 if you want to see that's a 3-D view 956 00:29:03,020 --> 00:29:04,819 of the pedal that I've almost finished, 957 00:29:04,820 --> 00:29:05,779 as was an early view. 958 00:29:05,780 --> 00:29:07,039 So it doesn't have a lot, you know, the 959 00:29:07,040 --> 00:29:08,929 guts of it. But so the next step is a 960 00:29:08,930 --> 00:29:10,999 pedal because although musicians, 961 00:29:11,000 --> 00:29:13,159 professional musicians have sound, people 962 00:29:13,160 --> 00:29:14,299 and people would come on stage and tell 963 00:29:14,300 --> 00:29:15,300 them to get off. 964 00:29:16,070 --> 00:29:17,629 People like me don't have sound people, 965 00:29:17,630 --> 00:29:18,799 and it's not really practical when you're 966 00:29:18,800 --> 00:29:21,019 playing to to tap on a touchscreen. 967 00:29:21,020 --> 00:29:23,149 So but I pedal, on the other hand, it's 968 00:29:23,150 --> 00:29:24,799 really practical and it's really easy. 969 00:29:24,800 --> 00:29:27,169 Just put it, take away all the Android 970 00:29:27,170 --> 00:29:29,089 problems having to send our Reno in 971 00:29:29,090 --> 00:29:30,229 there, except that our units don't have 972 00:29:30,230 --> 00:29:32,569 much RAM for programing. 973 00:29:32,570 --> 00:29:34,939 So I have to make it really sloppy code, 974 00:29:34,940 --> 00:29:37,009 but it works. And all these things work, 975 00:29:37,010 --> 00:29:38,929 and I'll be in the hardware hacking area 976 00:29:38,930 --> 00:29:40,369 later for anyone who wants to any more 977 00:29:40,370 --> 00:29:42,259 details or wants to play with it and 978 00:29:42,260 --> 00:29:43,260 stuff.
