If you are looking for a new microcontroller project and like to play with LEDs this 4 RGB LED PWM Controller project might be for you. There is full documentation provided. "The advantages include the built-in 4MHz oscillator, hardware USART, and ease of reprogramming. A couple of features I had in mind during the design: Multiple intensities for each color (using PWM) Multiple individually controllable RGB LEDs High-speed update
David Jones explains CMOS SCR Latchup in his latest Electronics Engineering Video Blog post.
Here is a great example of a DIY amp project. The TDA2050 Hi-Fi Chip Amplifier looks like a good chip to use for this purpose. There is full schematics and details provided so that you can build your own. Thanks Gio. "The amplifier is built around a single integrated circuit (IC), the TDA2050V which is produced by STMicroelectronics. From the data sheet, the TDA2050V is intended for use as
Here is a cool way to increase the functionality of your EeePC. Have a look at this hack that adds E-mail Twitter and Pidgin Notification using a RGB LED. Via: HG Forum "This is an interesting little modification that i have completed on my EeePC901. Based on an Atmel aTiny45 processor it’s function is relatively simple, but as it is built from scratch, the build took some interesting twists
Some computer companies like to keep their customers buying replacement parts direct from them and not from the local computer shop. That is the case with lots of products from the Compaq line. In this case the Compaq had a proprietary power supply but with a bit of hacking a normal one was able to be used. If you are ever in the situation where you have a Compaq
If you are looking for a compact, rugged, and cheap sensor filled package there is nothing better than a Wiimote. This Wiimote was Hacked to Analize Tennis Serves. It’s great that there is an abundance of creative people working to make interfacing to devices like the Wiimote a bit simpler than it could be if everyone was starting from scratch. Via: Hack a Wii "So if you are a
DIY Clocks are great since there is an inherent motion element. Most of the clocks that we use are very boring but that doesn’t have to be the case, have a look at this Arch Ball Clock for example. It tells the time in a very interesting way. Code and plans are available so that you can make your own, you could also purchase a kit from Nuts and
