Mini-Vox and Relay kit
 
The idea behind a VOX (voice activated switch) is that instead of the user pressing a switch to activate a relay, the sound of the users voice itself activates the relay. This gives hands-free control over devices like tape recorders. Power supply needed: 12VDC center positive 2.5mm jack. Electret microphone to pick up the sound is included. PCB size: 44mm x 48mm (1.73inch x 1.89inch).

LCD Temperature Meter kit (incl Box)
 
Introduces 3 1/2 digit LCD and the very popular 7106 IC. This IC has been used in low-cost multimeters for over 13 years. We use it to measure temperature using an ordinary signal transistor as the sensor. Data sheets are provided as is a breadboard area so you can extend the circuit to build your own voltmeter, ammeter, resistance meter or extended-range temperature meter. Takes away the mystery of how multimeters work. Box provided. 9V battery operation.(CPS2)

18W BTL Audio Power Amplifier
 
This kit contains the essential components to build a low voltage, high power mono 18W Bridge Tied Load (BTL) amplifier module using the Hitachi HA13118. The circuit is straight out of the data sheet. Only a few external passive components are required to make the module. The IC contains surge protection circuits and thermal shutdown circuits. The speaker and cables are not included. (CPS105)

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"
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.

6 - 10W Stereo Ampl Mod using TDA2005
 
Kit 143 is a class AB stereo audio power
amplifier designed for quality hi-fi
applications using a TDA2005 module. It is
easy to construct and has a minimum of
external components. The module has output
current protection and thermal protection. This
is the data book circuit which produces an
excellent sound. The supply voltage required
for this kit is 8 - 18V DC at 1 to 2 Amps.
