[sdiy] making a mixer

[VJ Holo]

hi everybody...(in a Dr. Nick Riviera voice)   
   
    I am new to the group. A few years back i took a class called
"Hardware Hacking"  with a guy named Nick Collins at the School of The
Art Institute of Chicago, for the rest of that summer i built
mini-synth( oscillators) and had all sorts of fun experimenting with
differnt diodes, caps, and resistors.   I am now trying to gather
materials to make a Pocket DJ Mixer.  I saw some on the market years
ago, and cant track it down... but i am looking for something a bit
more "tailor made"  I use two pocket samplers for live performance,
and i want  to make a DJ mixer with a cross fader that will be small
and get the job done...

    could anyone offer technical details like, what should i buy from
Digikey for a cross fader... or things to think about to keep sound
levels their cleanist.

Thanks

K.
