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 [...]
Have you ever wanted to have charger for your Nokia mobile phone on your bike? Nokia launches Bicycle Charger Kit for 15euro. Nokia says that Bicycle Charger Kit starts charging at walking speed (6 km/h) and stops when your speed reaches 50 km/h. The total charging time varies depending on the phone and the cycling [...]
Mikroelektronika have updated several special offers for dsPIC30 development tools. Special offers that has contained EasydsPIC4A Development System now contains EasydsPIC6 Development System. The affected special offers are: Easy Start 1 Kit – dsPIC, Easy Start 2 Kit – dsPIC and Easy Start 3 Kit – dsPIC. Beside this change, mikroelektronika have also added two [...]
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.

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).

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.
In [...]
This project allows instant start sequentially but a dozen low-voltage lamps 12 V / 60 W, and makes them fade and always sequentially (but slower). This system has been designed to meet the demand of a visitor who wanted ten recessed low voltage spot in a driveway to his house, with the following function: – [...]
This circuit allows switching on a LED when the battery voltage (12V) drops below a certain threshold. The operating system is based on a comparison of tension, which comes in a zener diode. If the supply voltage is 12V and the zener diode is a 10V model (this is the case in the diagram), we [...]
This is a good looking and practical device that can be useful in many areas where countdown timer is needed. This project is based on the PIC16F84A microcontroller. The time range can be adjusted between 1 and 999 seconds. This project has 3 buttons and one of them is named Set Button. In order to [...]
A VU meter is often included in audio equipment to display a signal level in Volume Units; the device is sometimes also called volume indicator (VI). In this project we are building a basic and low cost LED VU Metre circuit . The extent (range) display is -18 dBu to +3 dBu, spread over [...]
Today we have a new category “Projects” and a new electronic project 12 Channel LED Chaser with PIC16F84A.
This project is based on the popular PIC16f84A micro-controller.The heart of this project LED chaser is the PIC16F84A PIC microcontroller.A 4MHz crystal and capacitors C1 and C2 22pf is used for providing clock pulses to the micro-controller. The [...]
