Mike Szczys from Hack a Day shares a hack that he found by Geert on his Just a Thought blog. Geert wanted to jazz up his stairs but adding some DIY RGB LED stair lighting.

Thanks to Lior Elazary for sending in this great project. It accomplished a few things, he was able to justify the purchase of a laser cutter and his kids learned come computer basics. His Mechanical Bit Adder Clock is sure to be built by many since he also made a detailed Instructable for it. “The inspiration for this project came from trying to teach my son and daughter about

But if you look at it through the viewfinder of camcorder or
 If you are working on a vision system project that needs to track something your life just became a bit easier. Willem Schwalb just sent in a link to his open source software tracking system, Open Vision Control that can be used to control things such as automated turrets. You can also see lots more videos of the system in operation here. “Open Vision Control was initially created
 If you need to control some motors wirelessly this Wireless Motor Controller project by PyroElectro might be just the thing to get you kickstarted. The project uses SN754410NE chip to drive the motor and a XBee module to make the project wireless. “The purpose of this project is to build a system that can independently and wirelessly control two DC motors. To do this, the system will need
 A picture is a great way to show off a product, you can even take some pictures of the back and sides so the potential purchaser can see the product from other angles. How can you improve on this? Why not take pictures all around the item and play it like a 360 video. That is exactly what our friend Muris did. Check out his DIY Turntable Photography
