The heart of this project Intelligent Battery Charger is PIC16F628. Macobt found this project on this forum and he build it this project and he tested, and it works ok,  but there is several things need to be calibrated correctly to run the charger properly. Source: Macobt

The author of this project is Stanislav (Comodore) and he  explained how to make a simple fast blinking LED light that you can attach to your bike or any where you want. It blinks more than 3 times in a second. It is cheaper to make one than to buy one. You can make it [...]

Sony Corp.  said Wednesday it had developed what it called “the world’s first” prototype flexible colour video screen that is small enough to be rolled around a pencil. The screen consists of an ultra-thin flexible material covered in organic semiconductors, potentially pointing to a future of flexible mobile devices, television, electronic newspapers and magazines. The [...]

The world’s smallest transistor built with just seven atoms in a single silicon crystal and measuring four nanometres in length.The transistor, measuring four-billionths of a metre and embedded in a single silicone crystal, is the first step in a “quantum computer” which will make calculations millions of times faster than existing devices. Publishing their findings [...]

Siren is a very straightforward device but for beginners it is an excellent starting point since it directly interacts with real world via sound and is a great morale booster for next, more advanced projects that shall come. Source: Sindija1204

Soldering stations comes in a variety of prices and capabilities. The cheaper stations have a power controller, to control the power delivered to the soldering iron. More expensive stations will have a temperature controller near the tip of the soldering iron, and control the temperature using this feedback. The quality of soldering with a station [...]

The software is based on the HID demo from Microchip and has been adapted to interface the sensor instead of using a fixed mouse movement. The sensor itself is interfaced using the SPI protocol (see the sensor’s datasheet – ADNS 2610 Optical Mouse Sensor). Source: steffenschuette
