The Bent festival, which begins tonight in New York City, is a celebration of DIY musical instruments. Artists from all over converge to beep, blip, and strum for your pleasure. With a heavy emphasis on hacking your own instruments, this is definitely something we’re interested in. If you’ve only heard a little bit of circuit bending and didn’t like it, you may want to give it a try anyway. The musical genres are extremely diverse, it’s not all just random noise.
When [linux-works] found himself needing a switch that could convert coax to opto, he made one. The main chip is a cd4052 cmos analog switch, which he says is really cheap. The rest is pretty self explanatory. This setup can switch between 4 different inputs as well as do the coax to opto conversion.
If you’ve ever found yourself thinking, “I wish I had a laser projector hidden in a zippo”, then you’ll really appreciate this project. [Rog8811], who you might remember from the laser lighter, has made a spirograph style green laser projector that fits inside his zippo. This is very compact and you would have no idea it was there until you open it up. Just be careful, this seems perfect for causing eye damage to someone who isn’t expecting a laser to shoot out of your zippo.
