This project slightly modifies the Google Android sample app called "Bluetooth Chat" so you can type a message in the Android app and that same message will appear on an LCD attached to an Arduino Uno.   Source: circuit_breaker

This week we’ll send a Charger Alkaline Batteries PCB  to two readers. So if you want this PCB you can fill into the coments.  Magazine Emiter has described how to build this project with full details, so if you want this magazine you can buy from here.     Rules: Yes, we’ll mail it anywhere [...]

Mikroelektronika present you a new product- USB Charger board. You have probably charged your Li-Ion or Li-Poly batteries using large and heavy adapters, or some more advanced electronics. But those days are over. For a price of one battery, you can have a fast and reliable charger with MCP73832 charge management controller, powered directly from [...]

Long jealously kept electricity scheme for testing electrolytic capacitors, finally the pages of the Emitters.ESR-meter (Electrolytic serial resistance), an electronic instrument for measuring the degree of freshness (dry) of electrolyte fluid in capacitors, without dislocation of the experimental component of the printed plate.The device is built in miniature version on the two PCB, in addition [...]

This transmitter design is usually attributed to Japanese multimedia artist Tetsuo Kogawa. It takes audio input via 1 / 4 “phono jack, and built as shown, without additional antenna connection, will emit a radio signal about 30 feet.This is a standard model Mr Kogawa is the simplest FM transmitter, which is slightly more complex than [...]

After having seen so many propeller clockPOV videos on Youtube, but no real description of how they work or how to build your own, Chris made one also and documents how it was built. The Pyro Propeller Clock POV design criteria was short and sweet: be as simple as possible in order to encourage others [...]

Mikroelektronika present you a new better, faster, cooler looking and more powerful version of our universal development system UNI-DS6. It is the next generation in design and quality and has some wonderful features. With this board, you have 8 in 1 development board for the price of a single system. Pay only once for the [...]

Today i created pcb for Lithium Ion / Lithium Polymer USB Battery Charger with MAX1811, and designed with eagle pcb software.  About Max1811 The MAX1811 is a single-cell lithium-ion (Li+) battery charger that can be powered directly from a USB port or from an external supply up to 6.5V. It has a 0.5% overall battery [...]

This device captures the IP address of your network and it publish on site DynDNS.com. All without PC.  It allow a remote access to your LAN even if the IP address of the connections changes. If you don’t want to use the software provided by DynDNS, and then leave the PC switched on continuously, the [...]
