 A ATTiny24 is running the show here. This POV Wheel Display for a Longboard from ch00ftech looks like it took quite a bit of time to put together. Those tiny surface mount parts on the home made board must have taken a steady have to get right! There are more LEDs than microsontroller outputs but instead of using a serial to parallel chip to do the work the
If you have been listening to the latest episodes of The Amp Hour you have probably heard of Club Jameco. Chris from Pyroelectro has checkout it out, he purchased the 8X8X8 LED Cube to check it out. It is Arduino based and looks like a well thought of design. If you decide to give it a try it looks like you will need to set aside a large amount
Using a transformer for an old audio amp and a case made from an old computer power supply sure does make for a good looking DIY spot welder. It also has some smarts built in to detect when the welding electrode has been lowered to allow for a slight delay before the welding power is turned on. A pot is adjusted to change the actual weld time so you
Dan sent in a cool Automated Dartboard Score Monitoring project that he just completed. It is based around a dartboard that already has a ton of smarts built into it. The cheap ($15) dartboard has built in sensors that can detect what score area was hit and keeps track of the score on a built in LCD screen. How can this system be made better? Well you could install
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
 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
