Fresh hacks every day
[Michael] is a huge fan of old media formats. There’s something special about quarter-inch thick 78s, fragile blue cylinders holding music, and thin strips of mylar that preserve the human voice. He’s had an idea for a tape-based instrument for a while, and now that the Magnetotron is complete, we’re in awe of this glass harmonica and Mellotron mashup.

[Minisystem] has a thing for dynamo powered bike lights. He wanted to measure how well his latest is working, but just logging the current flow through the LEDs wasn’t enough for him. He picked up a cheap Lux meter and hacked into the circuit to log measurements while he rides.
He started by cracking open the case to see what … Read the rest
Here’s [Rob]‘s free form circuit that’s a Christmas ornament for geeks. It looks great, but sadly isn’t powered through a Christmas light strand. It’s just as cool as the skeletal Arduino we saw.
Well this is interesting: protoboard that’s specifically made to make SMD soldering easier. The guys at elecfreaks went through … Read the rest
We missed 60% of it already, but luckily you can easily watch the back catalog of [Alan Yates'] 2011 Advent Calendar of Circuits. As with traditional Advent Calendars he’s got a treat for every day in December leading up to Christmas. Instead of chocolate, the treat is a video about a different electronic circuit.
We didn’t find a playlist … Read the rest
Anybody who has a 3D printer always has a ton of useless plastic lying around. Some of that plastic may be from useless baubles, but most of it is in bad prints, short bits of filament, and general scraps. [Luke] found an interesting way to put those ABS scraps to use, and ended up turning trash into valuable plastic … Read the rest
Back during the Renaissance, great artists like Leonardo, Michelangelo, and Raphael would create their own paints. Of course paint is very cheap and readily available, but that doesn’t mean you can’t make your own paint by playing with chemistry.
Last summer, [Sean] at the Philly hackerspace Hive76 did some experiments with ferrofluids. For these experiments [Sean] prepared a bunch … Read the rest
[Dave Vandenbout] says that his sister has gotten big on Christmas traditions, and decided that the whole family should start making ornaments for the tree each year. Not one to let a chance to tinker with electronics pass him by, [Dave] started brainstorming the perfect electronic ornament for their tree.
He settled on the Christmas tree design you see above, … Read the rest
