  • Thanks! That looks like quite a nice one actually. My guess is that the LED might run it down though. If you don't mind opening it (you might do if you paid £20 for it :) ) then soldering wires onto the internal Li-Ion battery would be perfect. Espruino can run off the battery's 3.7v without needing the step-up converter.

    I've just ordered a really cheap (~£5) battery pack, so we'll see how that one works.

    In the mean time, I found that by removing the voltage regulator in Espruino it lowers the power consumption to around 20-30uA which means that even the small solar cell from the torch above is enough to run it, even today!

    edit: I'll document that in a bit I hope.
