The Dual Control R/C Car is what you get when you take an R/C car and stuff it full of electronics. I bet it was fun to build. 🙂 “The purpose of this project was to take a traditional remote controlled car and create our own control mechanisms. To control the car, we used a dual-axis accelerometer and LEDs (light emitting diodes) configured as photo-detectors. The control mechanism was selected
Check out Tokyoflash for a cool line up crazy watches. Here are my top 5 selections from their huge selection. 5. The Worlds Smallest LED Wristwatch “At only 8mm thin and 40 grams, the Retsu is just 1/3 of the weight of most other LED watches. The Vertical display runs in line with the edge of the strap forming a smooth transition from one end to the other. Amazingly simple
Here is a simple circuit to control 110VAC things such as Christmas Lights with low voltage audio. Be careful, high voltage AC can kill you. “The basic Idea was to have Christmas lights flash with the music. In my design I use an ordinary amplified computer speaker, a diode bridge, and a ‘CRYDOM’ SSR (Solid State Relay). In order to increase the time that the lights were on as
The Zune doesn’t appeal to me very much however it is nice to see that for the people that bought one it will be easy to “upgrade”. I just wonder how long it will take to “fix” the Wifi functionality. “This Repair Guide or Tear Down is designed to help you replace & repair parts inside your Zune and will help you replace parts needed to restore functionality to any
Here is a cool collection of computer aquariums, most of them are what is known as a Macquarium (made from a Macintosh). Links 1, 2, 3, 4, 5, 6, 7, 8,9 ,10, 11 “A Macquarium is an aquarium made from the shell of an Apple Macintosh computer. The term was coined by computer writer Andy Ihnatko as a joke (a jibe at the outdatedness of the Macintosh 512K) but Macquaria
If you want to play around with some LEDs, why not hook them up to some brains (a PIC chip) and have some fun. Pete provides all the details you will need to create your own Serial Controlled RGB LED PWM Driver. The provided firmware will run on the following PIC chips: 12F629, 12F675 and 12F683. “If you want to build your own multiple RGB LED display that you
PC Pit Stop has made a standard laptop battery catch on fire. The fire is quite a bit larger than I would have expected. “We intentionally created conditions in which the Li-ON battery pack would explode inside a generic portable. The results are dramatic. There are numerous conditions where these fires can occur in real life. Faulty battery packs (driving the recalls), faulty protection circuits inside the PC, exposure
