My new desk clock


Recommended Posts

Cool, I helped my son with a lemon battery project for a science fair many years ago. We put a whole bunch in series and got a decent voltage to light some LED's

Just goofing around, I do have some ideas on how to sustainably convert lightning into useable electricity. That sort of experiment requires a little more capital (and is a bit more dangerous)

They also sell them in the "man asile" at joanne fabrics / michaels / etc (where you find the model rockets, build your own robot, and every guy in the store who is waiting for his wife to decide on which color of yarn to buy for her next project) :P
