Here’s a cute little LED hack for your next soiree, it’s a solar charged piece of wood… with a motion controlled light in it!
[Zach DeBord] decided to try building his own version of this after seeing a commercial offering. He took a piece of oak and sliced off the top edge, and then laser cut the exact profile of the solar panel out of that slice. This allowed him to drill a nice big sloppy hole in the middle of it to fit the circuitry.
He’s using a nice big 8mm LED with a small 0.09V-5V DC boost circuit, a mercury tilt switch, a 4.5V solar cell, and a 2.7V 10MF super capacitor — plus a diode and 100ohm resistor. He’s glued the top slice of wood back in place, and sealed the entire thing with resin — you can hardly see the cut mark!
Leave the light with the solar panel facing up during the day, and when evening comes around, simply flip it on its edge to light up your table. And since it’s a super-capacitor, the circuit will likely last longer than you do. We’re not too sure how long the light lasts after a charge though.
Or if you really want to impress your guests, why not make a solar powered remote controlled lawn mower?
