Shep’s quad flexpicker packs 6 NXT microcontroller bricks, 22 motors and servos, and 26 sensors and muxes, and takes the form of four delta robots grabbing bricks from a conveyor. The grippers are pneumatic and are controlled via IR signals. So sweet! This system uses four parallel robots which are fed using two conveyor belts. […]
Anderson Cooper 360° featured Warning Signs, a project by NYU ITP students Nien Lam and Sue Ngo. These t-shirts, which are decorated with either a heart or lungs, change color when an elevated level of carbon monoxide is detected. Full details about the project can be found on Nien’s blog. Isn’t it great to see […]
Jeffrey Gough created 210 interactive, hackable badges for the TROOPERS IT security conference, featuring nixie tubes built in! Each conference attendee starts on zero. As they unlock achievements at the con – like sending postcards to their families, meeting the speakers, unlocking the secret in the badge, attending my SMT soldering workshop, etc, attendees level-up. […]
Here at headquarters, we’re cranking on producing the next issue of MAKE, Volume 27, themed Robots! What better way to celebrate than to host a fun, simple robot contest? We liked the open-endedness of our Volume 26 Karts and Wheels Contest (must have wheels and carry a person), and the cool, creative entries we got […]

This transmitter is commonly credited to Japanese multimedia artist Tetsuo Kogawa. It takes audio input through a 1/4? phono jack and, constructed as shown, without the optional antenna connections, will broadcast an FM radio signal about 30 feet.
This is the standard model of Mr. Kogawa’s simplest FM transmitter, which is slightly more complex than his most basic design in that it includes a trim capacitor to adjust the transmitting frequency. It can be powered by a 9V battery and uses a hand-turned copper coil.
Mark is a programmer who hates writing regular expressions. So he wrote a kind of visual regular expression generator that starts with the string to be searched, identifies recognizable patterns in it, and lets you select those you want. Then it outputs a working (albeit probably inelegant) regular expression to get the job done. The commentariat over at txt2re.com is somewhat predictably divided between grateful regex amateurs and annoyed experts. [via Boing Boing]
