It's a bitcrusher!

It's not a finished product yet, but it the circuit is. Hook it up between a guitar and an amp and it's perfectly playable. The board on the bottom is an arduino microcontroller, which takes a 10 bit sample of your signal and converts it to 6 bit before spitting it out across the 6 white wires to a handmade digital-to-analog controller. PM me if you want to see the source code. The USB cable is just providing power to the circuit.

As for the sound, it's really cool. It's a great lo-fi distortion reminiscent of old DOS games (think Doom and Duke Nukem 3D). I'll upload a demo video if there is any interest.

talk about neet

Wow, awesome...my next project is going to be some type of controller. Do you have any schematics?

I'm at work right now but I will post a schematic of the whole circuit when I get home. In the meantime check out http://arduino.cc for more information on the microcontroller I'm using. Basically it's an atmel AVR chip with a special bootloader that runs programs written in a variant of C++. The rest of the board is voltage regulator, USB interface for programming, and breakout headers for the I/O pins. In this application it's serving as a really crude DSP.

anyone info on this? Would love to see the schematic.

Ahhh excellent!

I had a short lived burst of enthusiasm with arduino a while ago. Bought one and... it's still in the packet

This is neat!!

I'd love to make a DIY bitcrusher, really want to hear this!

Make a demo vid please?



Edit: Didn't realise until spacelordmother stated that this thread is hella oooooooold.


Dammit I'm a moron sometimes

I'd love to hear/see a demo!

...but then again you haven't logged in since 2011, so I don't suppose we'll get one. Blooooo.

I can give you the schematic right now. it helps to actually understand what you are working with.

you could also just skip this silly software non-sense and use an 8 bit ADC going into that same R2R resistor ladder DAC. if you discard LSB 2 bits, I would think that the input volume to the dac should be made hot to compensate for this crappy 6 bit resolution. you can save yourself the trouble of making an R2R ladder, you can just buy them pre-made in SIP from mouser. check under resistor arrays + networks. follow the datasheet and the marking on the SIP package.

too cool

Let us hear it!
