One evening in college, I learned a lot about the way telephones work after some excitement…

I was relocating a telephone line in a room we were remodeling. I had a habit of stripping small wires with my front teeth. I had stripped one wire of the pair, and I stuck the second wire in my mouth to complete the pair. Apparently, the first wire I had stripped was laying against my nose when the phone rang…

I saw stars…and colors…and I bit my tongue…and I had a burn on the side of my nose for several days.

…and I went out and bought some decent wire strippers.

How about a pile of stuff from Ding&Dent for the showcase? Seems like there’s fun to be had there.

Note that near the top center of the schematic, there’s a connector for “TRIAX_ACCEL_BREAKOUT_MMA7361”.
That’s this:

It’s an accelerometer that can detect things like being stomped on.
I haven’t dug through the code to see exactly how the accelerometers are read, but I’d guess that they’re used in a “click detect” kind of fashion where any sharp pulse (maybe only along the Z axis?) is detected and triggers what amounts to a keypress handler to control the snake movement.

Wow…there’s plenty to digest here. Thanks!
ObNitPick: Minor typo? In “What do I need?” section, should first bullet be “inkspace” or “inkscape”?

See Nate’s comment in the section below the first photo of the breadboard:
“I did not install a reverse protection diode. I only use center positive power supplies so I know I’m safe."
(…sounds like famous last words to me…)

Agree that the AVR stuff is fun to play with at the price point, but have recently been doing MSP430 stuff at work and ran across a deal that might be interesting for some readers. $4.30 for a couple of “value line” MSP chips and supporting board for experimenting.

Yes, you’ll need to do some multiplexing. You want to rapidly sequence through each digit, not turn them all on simultaneously.
See http://www.mikroe.com/en/books/picbook/7_08chapter.htm for an example.
