If you need a cool way of monitoring your computer performance this DIY Computer Performance Monitor which is based on the PIC18F2550 should fit the bill. “The 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.”
With this simple IR receiver you are able to take command of your computer from across the room using a simple IR remote control and WinLIRC. Best of all the receiver should cost you less than $15 to build. “WinLIRC allows you to transmit and receive standard infrared remote control signals. This allows you to control your computer using almost any standard infrared remote control. It also allows your computer
Over at the Arduino X10 Collection site there is a two part series in the making of a DIY Geiger Counter Project which is built with an Arduino Microcontroller. Part 2 can be found here. I can’t think of a time I was looking for a geiger counter but you never know. The project is built around a Russian Military SBM-20 Hard Beta and Gamma GM Detector. If you are
In this GSR-Monkey (Skin Conductance Measurement System) Martin Sona uses the principle of galvanic skin response to plot some data onto a grid. Two people can be connected and monitored at the same time. I can imagine using this system as a two way lie detector, how often do you get to turn the tables when performing a lie detector test?

If you need to monitor a fan on a piece of equipment this PC Fan Failure Alarm from PCB Heaven should fit the bill. The RPM monitor line is used to determine what the RPM of the fan is and if it falls below an adjustable threshold the alarm is tripped. Heat buildup due to a faulty fan can do some serious damage in a short time, this simple circuit
Next time you are going to be leaving your house unattended for a long duration why not allow your house to send you a text message if there’s an intruder? That is exactly what Noel Portugal did with an ioBridge module and a few motion sensors. If that wasn’t enough the ioBridge has been programmed to pan the camera in the direction of the motion. If you want an ioBridge
The guys at Openschemes got their hands on a Zero Plus Logic Analyzer, they purchased the cheap 16 channel version and soon learned that with about $5.00 in parts they could convert it into the same hardware as the more expensive 32 channel version. There are some very fine pitch parts to solder so this mod isn’t for the beginner solderer. There is also a final step of making the
