USB-PC 8-CH Power Switch
Posted on Wednesday, April 21, 2010   •   Category: USB Circuts


PowerSwitch provides 8 bits of parallel output intended to switch e.g. the power supply to electronic devices. The PowerSwitch firmware is accompanied by a command line tool for Unix to control the device. (The command line tool can also be compiled on Windows using minGW and libusb-win32.)


USB LED Load
Posted on Tuesday, April 20, 2010   •   Category: USB Circuts


The board supports driving two separate tri-color LEDs. More can be setup inline if desired. Currently the software only uses the second LED and its color represents the CPU load of the system in real-time. Blue for idle and gradients light blue, green, yellow, orange, and finally red indicating heavy CPU utilization. If the system fails to respond, the LED begins flashing RED to indicate a lack of communication from the software. This lets you easily identify a crashed machine in a rack for example.


LCD 2 USB
Posted on Tuesday, April 20, 2010   •   Category: AVR


LCD2USB is a open source/open hardware project. The goal of LCD2USB is to connect HD44780 based text LCD displays to various PCs via USB. LCD2USB was meant to be cheap and to be made of easily available parts. It is therefore based on the Atmel AVR Mega8 CPU and does not require any difficult to obtain parts like separate USB controllers and the like.


AVR-USB Remote Sensor

RemoteSensor is a wireless thermo- and hygrometer with an USB port on the receiver. You can draw fancy diagrams of temperature and humidity for up to 16 wireless sensors.


Intelligent NiCd/NiMH Charger/Cycler with 128x64 Graphical LCD
Posted on Tuesday, April 20, 2010   •   Category: Battery Chargers


The accu cycler project presented here is an excellent solution for charging and discharging NiCd and NiMH accumulators for R/C modelers and others who make use of these accumulator types. With its performance it is very close to the many of the commercial products available on the market.
