Bonsai Throbber Prototype

Bonsai Throbber Prototype

This is my new bonsai throbber prototype. It uses an AT-Tiny26 from Atmel to provide control of an LED, which pulses every 30 seconds or so when the two supercaps are charged up enough (3 volts or so).

I am using a high intensity white LED, but you will get better life out of a red LED since they will use about 1/4 of the current. When fully charged, I get around 6-8 hours of throbbing.

Also note: this is a THROBBER, not a PUMMER, and the led smoothly ramps on and off over about a half second.

Also also note: Code and makefile for GCC is included below, and is a pretty good example of how to build a power saving idle sleep mode app with avr-gcc.
