This article starts out with basic LED arrays and controlling them with an Arduino. Then it gets into the more complex stuff, like controlling the array with a computer. Finally, he explains how to use a web-cam and Processing to convert the video signal into an 8X8 LED matrix. All the source code and schematics […]
The “CordWrap” is a simple addition to any wall power outlet. Simply replace your current outlet cover with a cut metal fitting with its ends protruding from the surface of the wall. Use these protruding ends to wrap the extra cord around it so that it doesn’t clutter your floor. Another benefit of this design […]
Todbot’s wrap up (and slides) of The Sketching in Hardware ’08 conference! The Sketching in Hardware ’08 conference was held a RISD in Providence, Rhode Island this year. Both RISD and Providence were very welcoming and I think we had a lot of fun. Once again, Mike pulls off an awesome conference. For my talk, […]
Even when they’re relatively small scratches in an LCD monitor can be an ongoing nuisance. If you’re willing to try reworking the display surface yourself, then consider this strategy using paper mask and spray lacquer – DIY How To Fix a Scratched LCD Monitor More: How To – Revive scratched plastic lenses
This balloon-based anti surveillance camera project by Brooklyn-based artist William Lamson is an easy way to fool even the most sophisticated forms of surveillance technology. Helium filled rubber balloon set to the correct height and covered with enough static electricity to stick to any surface, such as a public camera. Now if only they made […]
Rick Roll in semaphore. Controlled by an arduino and two stepper motors….
Pete writes in… Talk about retro. I hand coded this page (for the first time in years) describing my homebrew spring constant measurement experiments. This is really the starting point for solid material characterization. If you have something cool that you’ve made with that chemistry kit, you should take a look to see how you […]
