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)

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)

Serial Isolated I/O Module (kit)
 
8-Relay Module (mains rated - 110V and 250VAC.) An extension of our Kit CPS74 (see next kit), PC controlled 8-Relay Board with 250V switching relays and added features. It is in a plastic case, latched relay operation, 250V relays switched in safety by using Dinkle connectors, and with 4 external inputs. Uses serial port so it can be located over 100 yards from the PC. Comes with case and end panel pieces as shown in the photos. Requires a center positive 9-to-12V DC power supply, at least 500mA, 2.5mm jack. (CPS108)

Continuity Tester
 
Two range tester will buzz up to 3 ohm LO range, and 185 ohm HI range. You can set your own ranges by changing resistor values connected to the LM324 quad op-amp. Full circuit description, PCB and components supplied. A Continuity Tester is one of the most useful pieces of test equipment to have. It is used for testing the electrical path (continuity) between two points. It is more useful and efficient than using a multimeter to do the same job. This Continuity Tester has an audible output so you can keep your eyes on the probe tips while working. In addition it will only 'buzz' through a specified resistance or less. Above this value the tester will not make any sound. A switch is provided to allow this resistance to be varied. The Tester runs from a 9V battery (not supplied). The tester will 'buzz' up to about 2.8 ohm for the LO position and up to 185ohm for the HI position (this may vary slightly due to component tolerances). PCB size: 51mm x 38mm (2" x 1.5"). (CPS110)
