Introduction: The Biscuit Box

About: Question: Who is this D10D3 guy, and what is his deal? Answer: I'm a Maker, a hardware and software hacker, an artist, and general dreamer. I have an insatiable need to build things and modify them. I'm a ...

I like to make music with portable devices, and I needed a way to mix all of their signals and amplify them. Sometimes I want a speaker, sometimes I want headphones. I don't need a lot of channels or a very complex system. Nobody makes this device. Anything similar is much more complicated and VERY expensive for my budget. SO eventually I decided I could built such a thing. Thus was born:

The Biscuit Box: A three channel amp/mixer for portable devices.
Features:
3 channels in (all Mono)
2 channels out (one mono, one psuedo stereo)
Speaker that can be turned on/off
Master Volume plus Vols for each input.

Yeah, it's not exactly high tech. Nor is it terribly well built. But I'm a rank novice with electronics and this is by far the most complicated thing I've built. The amplifier is the guts of an off the shelf RadioShack mono amp. It's not really great sounding but I'm just playing for fun.

    This is exactly what i need minus intructions

    The reason I haven't is because it doesn't quite work right. It more or less works but something is screwy with the volume pots. Until I can get someone to go over the wiring with me and sort it out I don't want to post an Instructable with a faulty wiring diagram. Sorry.
