Casio QV-200 Digital Camera Cable. :  Lose your cable? Build it yourself and save $29. Fits many QV models.    (electronic construction project added 2/06)

Choc Block Supply:  A very simple adjustable power supply can be built on a single piece of chocolate block based on the L200CV IC. The output is variable between 0 and 30V, with an adjustable current limit up to 2 amps. (electronic construction project added 2/06)

Desktop Power Supply from a PC:  This ATX PS board has leads for +5 (RED), -5 (WHITE), +12 (YELLOW), -12 (BLUE) volts, Ground (BLACK) and switch (GREEN). Dell power supplies manufactured between 1996 and 2000 do not follow the industry standard pinout and color codes. The fan has also been unplugged for better viewing. Since this PS was converted for use in the logic and robotics labs, the selected voltages were tapped. Other users may want combinations of +3.3 V (ORANGE), +5 V and/or +12 V if they are converting one of the newer supplies. For R/C applications, the 5 volt output can also serve as a desktop source to drive receivers and servos. If used as a power source for the micro and sub-micro servos, you must be careful not to drive the servo to either endpoint to avoid stripping the smaller gears in these units. Most standard servos have sufficiently robust gear trains and will simply... (electronic construction project added 2/06)

Digitally Controlled Dimmable Lighting:  This project implements the control of 2 lighting sets using a PIC18F252 microcontroller. The advantage of the digital controller is its increased flexibility. The brightness of the light sets are controlled using phase angle firing method, but with the intention of investigating the implementing of a burst firing method.
