12V DC strobe Xenon Flasher
This Kit builds the circuit to trigger a high voltage
xenon flashtube using a 12V DC input from a power
supply. The flash rate can be varied between 1 and 2
flashes per second using an onboard potentiometer.
Component changes can move the flash rate range
faster or slower.
The Kit is constructed on a single -sided printed circuit
board (PCB). Protel Autotrax and Schematic were used
to design the board.

Touch/Contact Switch
Both types of switches are built onto the one PCB so you can see and explore how each type works. A battery can power the touch switch (2 contacts) but a power supply (like CPS4) must be used for the touch plate (1 terminal) to work. High quality 12V relay rated at switching 240V/3A supplied. Uses 14011 IC. (CPS10)

Stereo Preamplifier - Tone Control Unit
This is a preamplifier and tone control unit
which will make a useful addition to any
of our power amplifier kits. It is extremely
easy to construct due to the use of a special IC,
the Philips TDA 1524A. This contains all the
circuitry required to provide up to 20 dB of
voltage gain, +/-15 dB of bass and treble
control, channel balance, and a switchable
loudness contour.

Servo Motor Driver using PIC16C71 1-4
Using a PIC 16C71, a crystal, 8 resistors & 4 capacitors this kit will independently control up to 4 servo motors. We do not supply the potentiometers or servo motors. (a Futaba FP-S148 was used in the tests.) 5V DC power supply required. Full instructions provided.
Servo motors are used in radio-controlled models (cars, planes), robotics, theme park special effects, test equipment, industrial automation. At the hobbyist end of the market they are small, compact and relatively inexpensive at around US$20. The motors themselves are black boxes which contain a motor, gearbox and decoder electronics. Three wires go into the box; 5V, ground and signal. A short shaft comes out of the motor which usually has a circular interface plate attached to it. Most servos will rotate through about 100 degrees in less than a second according to the signal input. This kit will control up to 4 servo motors simultaneously. (CPS102)
