USB Relay Board

Here's the new 6 channel USB relay card for switching different appliances, lamps or motors by a computer program via the USB interface. There are certain switching sequences can be programmed via computer. The card was dispensed on SMD technology and is thus the ideal craft project for beginners and novices. Those who do not always wanted with his computer what Steruern. This can be done with the help of a web application even over the Internet. About the SPI connector could even imagine the relay card to cascade with other relay boards. The relays max. 250V AC and have a switching current of 8A (depending on the used relay). Furthermore also 4 inputs, which are separated optocouplers, and monitors can be queried. AVR simulates a USB RS 232 interface can thus this relay, the card without problems using a terminal program or other software to be easily addressed. The USB driver in the AVR firmware was developed by Objective Development ( http://www.obdev.at/products/avrusb/projects-de.html ) and under the GPL2. Through this USB driver could have very special devices and SMD technology abandon. Her come out is a very compact board with dimensions of 100mm x 85mm. The setting of the simulated serial port is: 9600 baud, 8Datenbits, no parity and 1 stop bit further handshaking. To power supply reaches a normal 9 - 12V power supply.

Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
