Murphy Mac sent us a link to a handy find/sed command that simulates the DOS tree command that you might be missing on your Mac or Linux box. find . -print | sed -e ‘s;[^/]*/;|____;g;s;____|; |;g’ You can see the result in the image above. Like most things I’ve seen sed do, it does quite […]
You can connect to the Wii remote over bluetooth or use an Arduino to send peripheral data to the Wiimote, but what if you want to interface directly with the Wiimote’s IR camera? The sensor is particularly good at tracking coordinates for 1 to 4 points—it could be a simple way to add sophisticated tracking […]
Ian Lesnet sent in a link to his Bus Pirate project, a universal bus adapter that lets you interface with most standard integrated circuit serial protocols at different voltages – all from you PC’s serial port. The idea is that you can debug, test, and prototype ideas a lot faster if you don’t have to […]
James Delaney’s created The Unfocused Brain, an interesting variation on Mitch Altman’s Brain Machine: This program and schematic is designed to flash LED’s in certain brain wave inducing patterns. The device is controlled by four buttons that switch the generator between Alpha, Beta, Delta, and Theta frequencies. … After building and trying out the SLM […]
Turn off TVs by just looking at them – By Mitch Altman…. “Hey, you mind turning that thing off?” Simple enough question, but I got tired of people looking at me like I’m from Mars. When a TV is on in the room, I can’t think. I just stare at the thing and drool. So […]
Last week I mentioned that adding &fmt=18 to a Youtube URL, or &ap=%2526fmt%3D18 to the embed code URLs allows you to view and embed Youtube clips in nice looking 480×360 resolution, encoded with the H.264 codec. The result is a much better playback experience than the standard 320×240 sorenson encoded clips, but a post today […]
Via Discovery News: Scientists in California have developed a software algorithm that automatically creates a physical key based solely on a picture of one, regardless of angle or distance. The project, called Sneakey, was meant to warn people about the dangers of haphazardly placing keys in the open or posting images of them online. … […]
