This project implements an intelligent LED lamp controller that is used as a replacement for incandescent bulbs in a camper or recreational vehicle. The controller board plugs in in place of standard 1141 bayonet bulbs and uses less than 1/10th the power. This light provides numerous advantages over the traditional bulb especially for dry camping where every watt of power used is important. This project also makes an excellent emergency lamp when combined with a gell cell battery. This project has been prototyped and tested over the past year. I do not have circuit boards or kits for building this project but it is simple enough to be built on a breadboard. [more]

To control a webcam with two servo motors (pan and tilt). Easy and simple to build, only need some basic knowledge about electronics and programming. This circuit is based on a PIC16F84 Controller. The total cost of the project is about 40 Euro (40$) including two servo motors and one PIC16F84. All the software/code can be downloaded as free or shareware.[more]

USB LCD/VFD Controller is a HD44870 based LCD/VFD controller via USB interface. The control command is compatible with Matrix-Orbital’s LCD module.So, you can use any MO friendly software to control this baby. Such as LCDC.The firmware are based on David Potter’s Serial LCD/VFD Display.Some features :this project uses a FTDI FT232BM chip as the USB bus controller,upports industry-standard LCD interface ,Configured for 16×2,20×2,20×4,40×2 LCD/VFD module,include hardware 19200-baud RS-232 input,the LCD/VFD can configured via commands.control with Microchip PIC16F873 MCU ,use 93C46 to store data.[more]

A PID (proportional-integral-derivative) controller measures a specific variable (such as water temperature) in comparison to a predetermined setting (ideal temp). The controller then performs a corrective action via its control circuit in order to reach the desired setting (i.e. - increases power to the burner). Result = dinner cooked up just right.[more]
