  1. From http://mayhewlabs.com: Is possible? (i forgot almost everything about midibox in the past two years. sorry) http://mayhewlabs.com/products/rotary-encoder-led-ring thanks
  2. I used the circuit module din and dout. The board was tight, both top and bottom ... only midi. I thought it would be slow, but not as much as I expected. The last two buttons will change color in accordance with the MIDI clock. Not too fast, but enough. The camera did not help, but you found it slow? The code was created from scratch, peak hold and range of the specific Meter shows a lot about the beat. I thought it was cute! Rather more LED, but there was plenty of room on board for more 74HC595. I did not like the response of the buttons, but as there is not to cue juggling, worked well. but could be better. Change the design at run time without testing is always a mess...
  3. As you can see, I'm having a little fun.

    All on

    u can see more info in there is a link to the original idea.
  5. More Photos! The faders are the Behringer mixers. They are very soft, and never failed me, not scratched. And eh ... are well used. Tomorrow a video... Bye!

  7. Thanks! It's Hand made, based on wackazong (Ander) idea, to use acrylic. (). But this rectangular form do not works well, it's very difficult distribute the force applied from any part of the button, to the tactile switch. My first Prototype was a square button with the tactile on bottom of the square and the leds on center of button. Works Perfectly! I should made square buttons... I can post the cad drawings of the square buttons if you want, but im warning you: would need a Dremmel (rotary tool) to cut the acryl and to made the outside structure. As you can see in the photo, i use double-sided copper plates. Its really a good idea, because the copper reflect the light from inside the button. I need of an idea to keep that shiny aspect of the copper... In next step of the project, i will make this buttons, but only in summer (this buttons are very laborious). It's a pun with TraKtor and all their controllers called Kontrol (S1,S4,K1 and F1)...
  8. Hello! Yes! Another Traktor Controller... (YATK) Here some photos and soon more infos about my project. I'm finishing the autocad beta layout.
  9. Hello Guys! My project has a lot of LEDs and current is a bit high. Something around 500mA only for the leds. I made 2 supplies: 1 (7805) for the CORE. I'm reading 5,04 V. 2 (7805) for the Leds and buttons. I'm reading 5,02 V (oscilates a bit) with 500mA. BUT Its very, very, VERY HOT, whit a heatsink. I haven't tested for more than 3 minutes The main supply has something around 15V. In my last attempt i use a 5V switched supply (cellphone charger) that says 5V 750mA. So i tried to put her for leds only, and Im reading 4,93 V/500mA. (Its working about one hour and supply is just a little warm) Finaly the question: I can have some problems with the small diference of voltage between the core and leds supply? My idea is use two switched suplies, one of 750mA for core and other stuff. And another for high current. Anther question: whats the diference between the 74hc595 pin 16 and pin 10? (5v supplies) Thanks
  10. is possible drive an RGB anode comon led with 74HC595?? thanks
  11. Hey guys, my core stop working... First question. without Optocoupler, led (TEST IN3) still lit is normal??? thanks! Edit: I put a led direct into J13 whit anode in +, and catode in -. ok. led flicks whith midi in. but if i put it in pin 2 and 3 of optocoupler (anode in 2, cathode in 3). led dont flicks. Is Normal? its my second optocoupler i'm very confused... :logik: ...
  12. Estou usando uma core baseada no pic, é fácil de fazer mas tem muita desvantagem, em fim. Estava pensando em algumas alternativas pra gente ter esta por aki no Brasil... Primeira (e mais fácil): Agente pode fazer um pedido para o pessoal da SmashTV, mas o negócio é meio caro, e sem contar o frete. Vantagem que o STM já vai ter o bootloader e o chip vai tar soldado, perfeito. Segunda (mais difícil): Fazer a placa aki no Brasil, tem um pessoal q faz umas placas boas por aki. Comprar o STM por aki tmb (não procurei o preço). Problema é que agente ia precisar instalar o bootloader, outra dor de cabeça. sem contar a parte da soldagem q é bem difícil. De qualquer forma fazer isso sozinho é trampo. Tem mais alguém interessado, pra gente poder baixar os custos??? Aceito Sugestões. Abraço
  13. Hi guys, im using mplab to try compile my project, but wen i compile the project, i get an error. here is the cause: This explanation i found in readme of mplab c18. Referencing a variable declared 'extern' with an initializer causes an internal failure. For example: extern int x = 5; void main (void) { x++; } generates an internal error. The workaround is to remove the 'extern' storage class specification or remove the initializer. what should i do??? kill me? mysys dont work, mplab dont work... i dont have more ideas. thanks
  14. e ai turma, como andam os projetos!!! pedi um forum em portuga pra gente, agora fica mais fácil!!!! abraços
  15. nils! you can create a forum for portuguese? for guys from brazil, the topic in portugues its a madness....

    thankyou!
