lemathos Posted March 7, 2010 Report Share Posted March 7, 2010 (edited) Hello everyone I started a new project to control traktor and my idea is to have tactile contact. I did a test with arduino and it works well but I can only have 5 input by atmega: / and I need 88. I did some research and I think that xmega could do the trick but I do not know anything about electronics: / Here is a first draft in attachment I think this layer printed on transparent paper for laser printer and cover by pvc (1cm). It also requires that I find a way to channel light from LEDs My idea is to make a You see something unattainable? Can you advise me to touch the switch? I'm all customer comments Thank you very much Edit : I find a name for my interface => MS8 It's a smile to numark ns7 ... MS are my initial :) Edited April 4, 2010 by lemathos Quote Link to comment Share on other sites More sharing options...

lemathos Posted April 4, 2010 Author Report Share Posted April 4, 2010 (edited) Ok,so my work start : The interface : Larger view of the mixer : With the light effect (a simple leds for the moment) : The test platform with an arduino : The contacts (it's simple pinned) And to finish a The idea : Send a signal to a transistor instead a led and use this signal in input of a DIN Problems : I need about 80 capacitives sensors but with an arduino I can have only 5 :( I've think to use a arduino mega who have more I/O ... Have you an other idea for doing my all capacitive switchs ? All suggest are welcom ;) Edited April 4, 2010 by lemathos Quote Link to comment Share on other sites More sharing options...
lemathos Posted April 4, 2010 Author Report Share Posted April 4, 2010 I found good information here What do you think about the first schematics please ? How can I interface this with a DIN input ? a simple 2N2222 after the BC346 will be ok ? Sorry I'm a noob in electronics;( Quote Link to comment Share on other sites More sharing options...
lemathos Posted April 5, 2010 Author Report Share Posted April 5, 2010 I just make some test with a simple BC 337 and it's work good as http://www.youtube.com/watch?v=StshNHY_3E8. Advantage : Very low cost 7$ for 100 pieces Inconvenience : Need a direct contact So for a price reason I think that I'll use this BC337 solution. Question : How can I interface this with the DIN ? Like that ? I'll don't have some ground problems ? Thank's Quote Link to comment Share on other sites More sharing options...
lemathos Posted April 5, 2010 Author Report Share Posted April 5, 2010 (edited) Other question: I'll need 29 analog input, 100 digital input and 94 digital output. So 1 AIN,4 DIN & 4DOUT Can I connect all of them to only one core module ? (I've read lot of things and I've doubt) Thank's Edited April 5, 2010 by lemathos Quote Link to comment Share on other sites More sharing options...
lemathos Posted April 6, 2010 Author Report Share Posted April 6, 2010 I've just found a topic I've make some test for nothing but it's a good new. I'll don't need other coponents :) Maybe just a qt 110 for a metal plate under my vynils ! Quote Link to comment Share on other sites More sharing options...
