http://www.waitingforfriday.com/index.php/USB_Performance_MonitorThe USB Performance monitor is a PIC18F2550 based device which shows the performance of your computer using two analogue meters and a RGB LED. The design is based around a stock Hi-Fi VU-meter which is controlled using PWM from the PIC18F microcontroller. This project was inspired by a friend of mine who wanted a way to move his computer's HDD LED onto the desktop. After toying around with sending Windows performance counters over USB via the Generic HID protocol I came up with the idea of using a VU meter I had lying around to build a full USB Performance Monitor.
The complete project details are available on my website.
