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)

Opamp Function Generator

Good value-for money & simple circuit to generate square, (pseudo) sine and triangle waveforms in the audio range. Uses quad opamp LM348.

You do not need a lot of money to have access to square, triangle or sine waves in the audio range. This simple kit uses four operational amplifiers (opamps) to deliver these waveforms in the 6 Hz to 7000 Hz range. The sine wave is a pseudo sine wave produced by a very simple wave shaping circuit.(CPS23)

Oscillator Building Blocks

Build and experiment with astable, monostable and SR flip-flop multivibrators(MV)on one PCB. 6 LED's & 9V battery-powered. Good introduction to electronics. Oscillators are everywhere in electronics. They are a basic building block upon which the whole structure of electronics and computers is based. This kit looks at the 3 basic types of multivibrators. They are designed to have zero, one or two stable states; the astable or free running MV, the monostable MV (also called the one-shot) and the flip-flop or bistable In the flip-flop MV a trigger pulse or control signal is required to change from one state to the other. MV's use regenerative (positive) feedback; the active components present within the circuit operate as switches being alternately cut off or driven into saturation. These circuits have now largely been replaced by timer ICs like the 555. (See CPS111.) However, a basic understanding of them is still essential since they are still used in many circuits.(CPS9)

Audio to light modulator kit

A music-to-light modulator is a circuit which controls the intensity of one or more lights in response to an audio input. The kit is ideal to give the rhythm to any party or disco without much money. Very safe operation as it uses an opto-coupler as a coupling device between the audio and the mains controlling stages of the circuit.
Input trigger voltage: 2.3 - 2.5V (min)
Operating voltage: 110 or 250 VAC
Power handling: 220W @ 110V or 500W @ 250V
PCB size: 2.16" x 1.63" (To help in the decision to select an enclosure keep in mind that the heat sink used in the kit is about 1" tall.)
PLEASE NOTE, THIS KIT USES 120V MAINS ELECTRICITY AND SHOULD NOT BE ATTEMPTED BY ANYONE WITHOUT THE PROPER SKILL LEVEL. THIS SHOULD ALSO BE BUILT IN A SUITABLE PLASTIC ENCLOSURE.
