Modding DJ mixers

Yeah I think they are just to hold it. Now what about the 5v.

Buy a hale UMC32+

The UMC is quite expensive, i'm using the teensy http://www.pjrc.com/teensy/ which has MIDI over USB support built in, making the whole thing smaller, cheaper and I guess a little bit faster. If it doesn't have enough inputs, you can add multiplexors, which turn 3 connections into 8 connections ...

you should be able to get some basic results without power, put your meter onto Ohms and check the resistance change ...

you'll end up with something looking like this for a while ....... https://www.facebook.com/media/set/?...3717172&type=3

my third conversion, nano-kontrol into an F1.

I've tested the terminals for the faders, was just unsure of what terminals to use. I will be ordering the Teensy board. Didn't know of it til now, thanx. I'm not a Noob, but not an expert (just fyi). The ? of power is pertaining to operating power once connections are made. I don't think sending power from the MIDI board to the mixer components are wise.

as long as you isolate the two sides, there shouldn't be a problem.

The Teensy is USB 5v powered, the mixer is ? ... my Berry has 5V, 12V and 19v rails inside, fortunately the faders and rotaries are on the 5V rail.

Can you get a schematic of the mixer? Normally if you ask the manufacturer they will have one for servicing the units. That'll help so much.

What you are doing isn't hard, but you just have to be careful. In all things, preparation is key. DO NOT START THE PROJECT until you have all the components needed. I've been caught short twice, and never again.

BTW check out the youtube vids on the teensy++ and the controllers already built with it like this one

or this one (very cool)

or this one (cooler still)

Thanx for all the info. Those controllers are cool.
