@dunkemhigh, cool, can you post some photos what's inside? I guess nothing interesting, a rectifier, capacitor and maybe not even a voltage regulator, because the description for the old version says it is brighter if the weight is higher. I could already think of some improvements, like blinking when the weight is at the bottom (could use a bigger storage capacitor and measure the power source), because if you are focussed on doing your homework or something (as intended for Africa), you might not notice the position of the sand bag and then I guess it shuts off quickly.
I just backed the new version.
