Since I had a (fake) teensy left with no project for it I decided to make a [http://blog.makezine.com/2008/11/13/the-brain-machine/ Brain Machine].

Basically it's blinking lights and beeping sound that put you in a state of total relaxation .. or something.


== Bill of Materials ==

* at90usb162 (fake Teensy 1.0 from $wellknownchinesevendor)
* 2 LEDs (blinky blink)
* 2 Resistors (68Ω)
* 2 capacitors (0.46µF)
* minijack-plug (ripped from an old dvdrom-drive)
* logarithmic stereo-potmeter (220K, volume control)
* battery-pack (pack for 2xAAA obtained, needs testing)
* some wiring
* old pair of laboratory glasses


I will make a socket for the teensy to fit in so I can take it out for use in other projects.

Since the µC can do much more than just blink and beep (and the firmware takes up something like 5% of the memory) I want to add some other features:

* a button that switches to a different meditation-mode (brain frequency)
* moar LEDs! \o/ (maybe a row of LEDs on the front that do a nice KIT-thingy, or some other spacey/trippy blinky-things)
* ... (suggestions are welcome :) )
