Sony show first "rollable" video screen

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 [...]

Scientists have created the world’s smallest electronic switch

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 [...]

Two Tone Siren with two NE555

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.

Homemade Soldering Station with PIC16F88

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 [...]

Optical USB Mouse with PIC18F4550

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).

LED controller with USB interface

This project is a full color LED-controller that can be configured via a USB connection. The color of the connected LEDs (common anode only) depends on the selected operating mode:Slow color change (ca. 40 minutes),Fast color change (ca. 2 minutes),Temperature base color (temperature range adjustable),Constant color 1,Constant color 2.Constant color 3 and Constant color 4.
