  • 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?
