9V Amplifier and 12″ Speaker in a 12″ Tom Drum Shell

Probably one of the weirder things I’ve built. This is a 12″ Celestion Modern Lead 70 Speaker and a 386 IC amplifier in a 12″ tom drum shell. When I built this, neon green duct tape was on sale. A lot of stuff I built had neon green duct tape all over it. The circuit is… Continue Reading →

RAGE: Richmond Area Gear Expo – April, 2015

Playing the theme from Jurassic Park on a 3D Printer

Hold on to your butts! Inspired by the old printer that played the E1M1 music from my favorite video game Doom, I decided to see how difficult it would be to get my 3D printer to do the same thing with the theme from Jurassic Park. (Spoiler alert: It wasn’t easy) I found a MIDI… Continue Reading →

Silver Spring Maker Faire – September, 2014

Whoops! Looks like I forgot to write about this one! The Silver Spring Maker Faire was produced by the Kid Museum, which is a hands-on museum that has a strong emphasis on DIY learning. My kind of place! There was a museum like this in Sarasota, Florida, but chronic mismanagement and a greedy city government put an… Continue Reading →

Maker Faires, known as “The Greatest Show and Tell on Earth”, are events hosted or sponsored by Make Magazine where Makers gather to show off what they are working on. There are generally a small number of “Flagship Maker Faires” (hosted in San Francisco, Detroit, and… Continue Reading →
