Ultrasonic Pest Scarer
The latest Magenta kit (Published in EPE Magazine July 1997 issue) generates high intensity 32kHz Ultrasound to repel visiting feline and other pests. The design uses the 8 pin PIC12C508 to produce randomly timed Ultrasonic bursts of random duration - giving maximum confusion. There is a second signal output which alternates with the main signal and can be used to drive an extension unit. When the two are spaced either side of the area to be protected, the output of randomly timed bursts alternating between two sources gives further confusion over a wider range. The circuit is designed to be operated from a simple unregulated DC supply from 9 to 24 Volts. It has an internal voltage regulator. Several units can be run from a single plug-in power unit.
Power supply (will drive up to 4 units)
Coming out in the October issue of EPE Magazine is our new Pipe Descaler Kit. This PIC12C -- based design uses a full bridge audio power IC and a coupling transformer to deliver plenty of power to a coil wrapped around the incoming water pipe. A bi-colour l.e.d gives visual monitoring, and optional audio monitoring can be added using a push to make button and a piezo transducer. The circuit generates sweeping frequencies from 1.5 to 14 kHz ensuring the maximum effect. The kit is simple to build - using a single PCB with all components marked. It has an on-board voltage regulator and requires 250mA at 8 - 12 Volts. A suitable plug-top supply is available.

Magenta MKII Bat Detector
Our new Bat Detector design has been causing considerable interest in Bat groups all over the country. The sensitivity and low noise level make it easy to pick up many different species - even at a distance. June seems to be a good time for Bat watching - so if you are interested - now is the time to order. We believe it is the best value on the market.
The MKII bat detector has a compact easy to build PCB with a 'full bridge audio output IC which provides ample power to a built in loudspeaker, and optional 'personal stereo' headphones. The headphone socket does not cut off the loudspeaker, and so can also be used for tape recording. The loudspeaker is weatherproof, and is ideal for 'group listening.
The circuit is a superheterodyne type. covering 20 to 140 kHz - covering most of the Bats in the UK.
3 NOTE DOOR CHIME KIT
Ideal beginners project, uses SAB0600 chip to produce natural sounding 3 note chime. Adjustable pitch so that two can be used for front and back doors. Kit includes all components but no case or battery.
