With some conductive fabric and spirit gum, you can make a simple binary switch that attaches to your eyelids. Andrew Schneider used some of these to make a polaroid camera that takes a snapshot when you blink. When I first saw these, I was reminded of cyborgs in television and film and how they typically […]

David sent us an easy upgrade for the Bare Bones Arduino that will give it a couple cool features released with the new Diecimila Arduino, namely the ability to auto-reset after a code upload and a firmware update that will get the board running in 2 seconds instead of 10. With help from Paul Badger […]

The PSP hackers over at noobz.eu have released a killer tool for fixing any bricked PSP, restoring it to v1.5 firmware. When the PSP boots, the hardware checks for the serial number on the battery eeprom. If it’s 0xFFFFFF, it loads firmware from the memory stick instead of from internal flash. You use a working […]

NES.app is a full blown Nintendo emulator for the iPhone. It supports the device’s multitouch interface, so you can use the virtual on-screen game pad with your thumbs, just like the Nintendo gods intended. NES.app uses a heavily modified version of the InfoNES emulation core to mimic the 6502 processor in a Nintendo Entertainment System, […]

I used this process to restore an old wood plane that I bought for $1 (it looked totally un-usable because of the […]

When acetone is used as a solvent, the expanded polystyrene will easily dissolve and you’ll be left with a liquid acetone/polystyrene solution. As the acetone evaporates, the polystyrene becomes increasingly viscous: first pourable, […]
