Fresh hacks every day
[NeZoomie] built an RGB mood lamp as his first electronics project. He certainly hit it out of the park with this one, ending up with a design so clean it could be a commercial product. The controller is an Arduino board (further proof that this is a fantastic entry-level platform) that interfaces with 8 RGB LEDs. He’s built an enclosure … Read the rest
[Harm's] tumbling robot from a few years back is an excellent study in simple motion. Foregoing wheels or legs, he uses four flippers to roll the robot around the room. Two motors are used, each in charge of two flippers. Identical but separate circuits drive the motors with a 74HC240 gate IC monitoring the continuously rotation. When a flipper becomes … Read the rest
We’re sure you’ve heard about Xbox 360s facing an other round of bans from Xbox Live last week. It seems that living in a hole, or even in Grenora, North Dakota couldn’t help you escape hearing this from every news source possible. Apparently, this has caused a slew of banned consoles to go up for sale in a buyer-beware quagmire. … Read the rest
Here’s something that the R/C airplane crowd might think of as old news. These directions show us how to rework floppy drive and CD Rom motors to be high power airplane motors. There are several listed, with details on each, but those unfamiliar might want to start with the most basic CD Rom version. It covers winding your … Read the rest
We stumbled onto one of [Nik Melton]‘s projects, an Omni-car. It is omnidirectional, meaning it can go any direction at any time without having to turn. The body was designed by him, then printed with a 3D printer. The control scheme is what interests us though. He has found a simple way to wire it to get the job … Read the rest
[Pcmofo] has shared a well-built, well-explained example of how to implement an RFID key system for a door. We call this the right way because it is well thought out and functional. In the past we’ve seen doors that unlock via a secret knock, keypads, and RFID, but they are all non-permanent solutions capable being transplanted … Read the rest
