diy controller

Yeah that's what I'd like to use the center buttons for, Maybe have them on a shift so they control cue points or the sample decks.

OK I just ordered the big Teensy board with pins, the Teensy tutorial kit, a bread board, 30 Swana arcade buttons, a big pack of jumper wires and 50 of the 100k potentiometers. Haven't got any leds yet. This is something I'm gonna be doing with my 11 year old son.
Think I have all the basics covered for now unless y'all think I need anything else?

That's a lot of pots ehehe. where did you bought them? You can't connect all those pots directly to the teensy. You'll have to multiplex them. Later I can help you with this. Still have to buy the chip to multiplex too.
Well... with time you may need resistors for example for leds but at that stage you'll know a little of electronics. I think that the tutorial kit has some resistors for their leds.

Blimey. Bet that cost a fair bit. 30 buttons woah.
The uila leds are like a ring board that fits inside the button. They've been made specific for the transparent seimetsu buttons. They're like $4.97 each though.

Yeah... original Sanwa must have costed. I have like 20 chinese-white-brand arcade buttons and they cost less than half than Sanwa. I also have Sanwa lying around... well... it does have quality and are more silent.

I'm thinking I want our end result to be something like this first controller, http://www.djtechtools.com/2010/03/0...di-kit_review/
Plus it'll be quality time with my son, he's kind of a nerd, Lmao!! He like to build models, rockets, things like that.

Quality time! That diy midi is pretty impressive. The first one. I've seen it already online. Hard stuff: LCD, a lot of analogs (potentiometers: knobs and faders are potentiometers) and those little buttons with leds are hard to find at a good price.

Very nice. I would just like a midifighter style controller maybe be able to use the mf maps to make my life easier.

Pretty easy to do and with teensy you don't even have to do a matrix of buttons ehehe

EBay is where I got of the stuff, not the Teensy though. Here's the buttons, http://item.mobileweb.ebay.com/viewi...id=03528929971

I won't have the LCD screen, lol! Yeah I was reading about that multiplexer, that's a ways away for me, lol! Hopefully everything will be here in a few weeks and we can get started.

If you're from the states... I guess it won't take much. Here in portugal teensy arrived in like 2, 3 weeks.

Oh if it was black or white :P still a bit expensive.

Hard to get on the enclosure.

This one also seems nice but a little mini?

Thats how i would love the leds to work. not just on/off, they fully interact with the functions.
Im from england u.k so im guessing ill be waiting a while for a teensy.

Can i just ask, if i want a led on each button will i need to use a i/o on the teensy for each one aswell as each button? so i will need 32 i/o? best to go for teensy++2.0

That's kind of easy to do (the video you showed). Still is pretty interesting. The hard on that video is some buttons and knobs are hard to get around europe for a good price. For example those withe ones on the left and the knob on the bottom left.

As I said, I'm from Portugal and it took like 2/3 weeks to arrive and to come to Portugal comes first from UK.

Well... Yes. Each led, each switch, each digital input/output needs an input and of course ground. There are although ways to pass this without problem. One is the matrix i mentioned earlier. The beauty of electronics and everything works around the same kind of thing: electricity! So... The way to do a button matrix is the same to do the led one. I also have the teensy++ with pins. So in that specific you have 46 i/o, we have to subtract the ones for the encoders, digital encoders need specific interrupt pins (INT) and teensy has only 6 (i don't know if you can matrix them. EDIT: after a search seems to me that this isn't entirely true). So if you want two jogs and one browser knob well... there goes 6 pins. Anyway you get 40 i/o then. Dividing between a led to each button we can have a matrix of 10x10 (20 pins for the leds and 20 more for the butons) so... 100 buttons and 100 leds! That seems about right :P Of course that then if you want a lcd or something you'll have to get some i/o there also. If you don't think that is enough you still have shift registers (which I never searched because I don't need).

Anyway since I'm now thinking on using sync more than beatmatch i'm thinking on building something more on the lines of the X1 and the K2. Also thinking on something like the maschine. Thinking thinking and thinking... And no decisions. Well... at least I already have the knowledge now ehehe.

Just ordered my teensy++ and the tutorial kit. Not ordered any buttons as yet because i need to make my mind up on whether i want leds inside them. I have 3 weeks to decide before the teensy comes anyway lol.

you could have bought at least one to start testing and using.

How can I test it without the teensy?
