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 glassesNew 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 :) )
- Prototype working
- Main components soldered to perfboard (with socket for Teensy)
