Martin Raynsford has built a cool looking laser cut walking robot. It was cut from 3mm plywood which is also a favorite of mine. In the video you can see how smooth the action is. Looks like the built might have taken quite a bit of time since there are a ton of small pieces and each one was connected using bolts and locking nuts. The motor sounds a
Matt Richardson has taken some NXTChuck LEGO MINDSTORMS Wii Adapters and built a pong game out of the NXT system. I have never had a close look at the LEGO NXT language before, it looks much more robust than I would have expected. As most other platforms have chosen, it looks to be a variant of C. If you are planning on interfacing some nunchucks to your LEGO NXT and
If your last radio was picked up at a department store you might want to treat yourself to a stylish one next time. Check out this Laser Radio by Tom Kipgen from Tom’s Designer Radios. Nothing stock here! The image above shows a consignment job that he did for someone looking for a radio with a James Bond 007 feel. If you want to see a video of one
If you would like to take macro photographs with your iPhone or iPod you would be out of luck if you have a stock one in your pocket. But if you are like many of us your ever growing junk box of various pieces and parts might come in handy to give you macro capability. Seventeen year old Instructables user Radioactive_Legos has built such a device. He dug out
If you are thinking that this transformer is quite beefy you would be right. Youtube user Photonvids has designed it to be connected to 220V and it has an open circuit secondary voltage of around 4 volts. This means you can safely touch it with your fingers but I would step back if someone was planning to short it out with a crowbar. I guess that might be a
 Thanks to Noah Farrington for sending in his latest project which s a Wave activated Light. To make the magic happen he is using a ATTiny microcontroller, a voltage regulator, an ultrasonic distance sensor and a bright LED. The first version was done with an Arduino but that was overkill for Noah since he doesn’t need much computing power or pins. The small 8 pin microcontroller looks perfect for
Thanks to Sunny for sending in his latest project, the Raspberry-Pi Automatic Packet Reporting System called the piGate. “I present here, an implementation of an APRS iGate using the Raspberry-Pi. An APRS iGate is an Internet gateway that gates packets from the radio/RF side to the  APRS-IS on the Internet (and vice-versa). The APRS-IS is an Internet based network that connects APRS networks from all around the world and
