We don’t want your brains to explode, so just trust us that this is a truly one sided circuit. Being a mobius strip means that this circuit has uber geek bragging rights. Beware, your friends who have never heard of a mobius strip will argue until they are blue in the face that there are two sides to it. The circuit they chose was fairly appropriate, an LED “chaser”.
[Aki] had a broken TAC-2 joystick that was just begging for some new and improved use. Since it was the cable that was broken, [Aki] had the idea to make it wireless. He designed custom boards for the transmitter and receiver. Each is controlled by an ATTiny2313. He fitted it with the stock connector so it could possibly even still work on a commodore 64. He hasn’t tested that yet though.

[Joe] sent us this project called Laser Pup. After seeing many other projects with the ioBridge like beer pouring and dog treat dispensing, he wanted to make his own. His project allows him to play with his dog via a ceiling mounted laser pointer. We know, you were hoping for something more along the lines of Laser Cats, but this is still pretty cool. He built a web interface specifically for the iPhone to control the laser, room lights, and show a live feed of the puppy playing. You can see a video of it in action after the break.
