Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.

That's a good idea... I was planning to open it up to add a momentary button for the LEDs anyway.
I'm guessing the relationship between solar cell output for typical light level over 24 hours at various times of year, vs. charger/battery efficiency, vs. power drain by the Espruino (plus other drains, such as wireless modules) would be a pig to figure out.
Any rough guesses on whether the solar cell kept in daylight charging up the Li-Poly battery would be enough to power the Espruino with a typical(!) activity load in perpetuity?
