I made this thread because i recently started working on a DIY project that i thought i should share with you. The goal is to make a useful sampler sequencer using easy methods and cheap parts. 

Here is the basic idea for the main unit:

This is just the core idea so far. The final unit should have several preamplification stages with tone controls, possibly a tube preamp for the final stage, reverb/echo/delay in some form, ring modulator and a robot/pitch/vibrato voice modulator.

It should have the possibility to record from the arduino, through a microphone and a line in jack. Maybe i'll add a theremin if i can make it work or gets room for it in my box.

 

Not yet decided on the casing, but i have a wooden box from IKEA that might do the job.

I'll keep you updated on the project when i have something interesting.

Let's start off with a modification of the ISD1820 module:

EDIT: I just noticed it was not a 2K2, but a 100K resistor and that's quite a difference. 2K2 is too low and will result in awful quality recordings.

You are quite magical, Bellows, being able to change your audio recording board to the same one as mine just like that!

It makes learning a lot easier as well :D
