Evening Project: The Brain Machine
Recently, well 1 year ago, i readed in The Make Zine about a Project called “The Brain Machine”.
This is a modified Atmel circuit that claims: “Get altered states of consciousness with this microcontroller-driven sound and light device.” by Mitch Altman.

I really enjoyed listening to the Videos and wanted to try it myself, just because it looks so funny to sit there with brainlooping glasses in your face :)
So i decided to rebuild the whole Project but without the extra led’s that were original and without the Serial Connector because i have a Parallel ISP Interface for the Atmel Microcontrollers.
Download the firmware and instructions here:

(Scroll to “Project: Make your own Brain Machine (from MAKE Magazine #10)”)
I used these Schematics without all the Serial Stuff:

This device really rocks you into some deep trance state when you want it :))
