Since I had a (fake) teensy left with no project for it I decided to make a 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 New pair of flexible protective glasses bought (adv: easy to put on, holes for mounting stuff, glass can be easily taken out for painting and such)

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 :) )

Progress

• Prototype working
• Main components soldered to perfboard (with socket for Teensy)
