How long does that last?
Teensy + SparkFun thing + 2100mAh NiCd cell + 2 LEDs + buzzer runs continuously for about 1.5 days.
How much current does an arduino board draw from USB?
I can't say. The Teensy in my project uses about 18ma when the USB pad is turned off. About 22ma with the USB on. When put to sleep the project uses about 680ua.
The teensy looks very interesting, but not a complete arduino-clone.
Are you opposed to it on philosophical grounds or is there a feature the Teensy lacks?
