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.

Mini-Vox and Relay kit  (Out of Stock)
 
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).

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.
Specification
D.C. Input : 15V DC supply or 12V DC battery. 50 mA min.
Maximum output : > 3 V RMS
Maximum input : > 300 mV, G = 20 dB
> 3V RMS, G = 0dB. Input Z > 10 k ohm. Output Z < 300 ohm
Frequency resp. : < 10 Hz to > 50 kHz + / – 1 dB
THD at 1kHz : < 0.1 % at 1V output
S/N ratio : > 80 dB, G = 0 dB
Bass boost/cut ~ 15 dB at 50 Hz
Treble boost/cut ~ 15 dB at 15 kHz
PCB size: 4 inches x 2 1/4 inches. (CPS100)

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)

Dual HI / LO Switching Relay Board
 
The kit is based around the ULN2003A IC, a 7-channel high voltage, high current relay driver. The inputs are TTL compatible so they can be connected to 5V. LO 0-0.8VDC. HI 2.4V - 12VDC. Operating voltage: 12V DC. The relay will be operated when either the LO input is low (0 – 0.8V) or the HI input is high (2.4V – 12V.). Two 12V relays, coil resistance 400 ohm are used. It is rated to switch 250VAC at 12A. However, because of the PCB track thickness and width we do not recommend using the relay to switch more than 5A. PCB size: 2 3/4"x1 3/4" (CPS156)

5 Ultra Bright LEDs flash in 7 patterns
 
Five Ultra Bright LEDs flash in seven patterns. The modes can be cycled through using an on-board tact switch. When the desired flashing pattern is found move the PCB-mounted SPDT switch. The pattern will remain flashing as long as power goes to the board & the switch remains set. COB PCB size: 3x1.5 cm. Ideal for schools.(CPS37M)
