Automating a mechanical typewriter

typewriter-driven-by-automotive-door-lock-motors

Check out all the work going on in the cabinet below this typewriter. The hack which automates a mechanical typewriter  is for an art installation, but wouldn’t it be fun to build one of these to use as a résumé printer? It really makes us wish we had an old typewriter sitting around.

It would have been much easier to … Read the rest

Animated holiday wreath from a string of LED lights

animated-holiday-wreath

[Dennis Adams'] wreath lights project looks pretty good. But he did some amazing coding to produce a whole set of interesting animated patterns that really seal the deal for the project. Don’t miss the video after the break where he shows off all of his hard work.

He started with a string individually addressable LEDs. These are the 12mm variety … Read the rest

Roomba and virtual walls make up this theme family Halloween costume

It figures. You spend a ton of time making a cool set of costumes and then you can’t get your kid to pose for a picture. It’s okay though, we still get the point.

In this case, he’s using a wireless … Read the rest

Shovel…guitar?

We didn’t believe this hack at all when we saw it, or rather heard it. Surly a guitar made out of a shovel couldn’t sound decent. But the video (after the jump, skip to 2:40 for the jam) to our untrained ears sounded pretty rad. Could be the supremely well done wood work, proper use of tools, high tech pickups, … Read the rest

Bassoforte and other new instruments

[Diego Stocco] makes music with instruments he assembled. For instance, his Bassoforte uses piano keys, the neck and strings from an electric bass, and what look like some cymbals. Throw in a hammer from that piano and a double bass bow (plus heavy use of audio software) and he’s in business. Big business actually, his work has been in video … Read the rest

HDD actuated acoustical instrument

This is the multichord, a one-string musical instrument built by [Christopher Mitchell]. The string is a 20 pound mono-filament thread stretched between a wooden bridge and the read/write head of a hard drive. The idea is that the vibrations of the string are picked up and amplified acoustically by the sounding box that serves as the body of the instrument. … Read the rest
