5 Ultra Bright LEDs random COB Module
full documentation in acrobat format
(K52M)
Five Ultra Bright LEDs flashing in random or in sequence. Uses a COB (Chip-on-board) PCB measuring 3cm x 1.5 cm. The flashing frequency is set by a single external resistor between 300K and 1M ohm. A pad connected high determines the random or sequential flash pattern. A second pad connected low determines whether the flashing is continuous or set by a toggle switch. Ideal for schools. 2.0V DC to 3.6V DC operation. Operating current 10 - 16mA. Standby current is less than 1uA. (CPS52M)

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)

Square Wave Oscillator LN/NE555 (inc box
Simple circuit to generate square waves of approximately 1Hz 10Hz 100Hz 1KHz 10KHz & 100KHz. A square wave generator is one of those pieces of equipment that has many uses in the workshop yet few hobbyists actually have. This simple kit, based on the popular 555 timer IC, generates six preset frequencies from 1Hz to 100khz. It has an operating voltage range of 5 to 18VDC and even provides visual indication of the output. The kit is constructed on a single-sided printed circuit board (PCB). The PCB size: is 78 x 50mm (3.1" x 2") and will mount on a small plastic 'Jiffy' box. (CPS111)

1W Stereo Amplifier Module
Uses 2 LM386N-1 for a stereo amplifier. Ideal for walkman and other battery powered items. 4V - 12V DC. Instructions PCB and components supplied.
This is a 1 watt per channel, stereo amplifier module Kit using two LM386N IC’s from National Semiconductor. It is basically two of our CPS17’s on a single PC board, with a dual gang pot. It will operate best from 6-12V DC and will work well from a battery since the quiescent current drain is only 10 mA. It requires no heat sinks for normal use. The input and output are both ground referenced. Maximum output will be obtained with a 12V power supply and 8 ohm speaker, however it is particularly suitable for driving headphones from a supply as low as 4V. Speakers are not supplied. They should be rated at 3W or over. PCB size 63mm x 40mm (2.5" x 1.5"). (CPS115)
