IR Door Minder
 
This kit uses an infrared (IR) beam to monitor door & passage-ways or any other area. When the beam is broken a relay is tripped which can be used to sound a bell or alarm. Suitable for detecting customers entering a shop, cars coming up a driveway, etc. The IR beam is very strong. Distances over 25 yards can be monitored with this kit. A 12VDC unregulated supply is required to power the kit. A 12V wall adaptor is fine. Only one power supply needs to be used to power both units. The relays in this kit are rated to switch mains voltages. With power applied the relay is normally operated and only releases when the beam is broken. The relay contacts labelled “NO” (Normally Open) and “NC” (Normally Closed) refer to when the relay is released. The plastic tube is to put over the IR LED to direct its beam. This is needed when the barrier is only a few yards apart. IR transmitter PCB size:: 45mm x 30mm (1.77" x 1.18")
IR receiver PCB size:: 50mm x 48mm (1.97" x 1.89") (CPS130)

6V - 12V Screamer Alarm kit
 
Powerful 9V to 12V piezo alarm. Uses 556, auto-transformer and two piezo alarm elements. Circuit will deliver 108-110dB at 1M. Uses sweep circuit so there is no need to trim the circuit to match the cavity resonant frequency. We supply a plastic box with two piezo elements (35mm diameter (1.4")) already mounted in their own resonant cavity. This is part of a commercial alarm unit but it uses our (better!) drive circuit.

PIR Movement Detector
 
Circuit designed around a recently developed movement IC (KC778B). Circuit utilizes PIR detector and a light dependent resistor (LDR) to provide an optimized circuit that will detect motion up to 6 meters (18 feet) away. Operates on 9-12 VDC. Note that the PIR sensor & the PCB-mounted fresnel lens fit on the other side of the PCB; the solder side. This is to allow the unit to be mounted inside a container with the detecting lens poking out and the controls facing inside the box. PCB dimensions 3 inch x 2 inch. (CPS30)

ELECTRONIC WATCHDOG
 
A circuit that produces a natural sounding barking dog with a sensitive "ear" to everything that comes near it. It is a faithful watchdog, which never sleeps and never has to be taken out for a walk.

 
Specifications:

power supply: 2 x 8V AC or 9 - 12V DC / 500mA
choice of two different "dog sounds"
reacts to surrounding noise with adjustable sensitivity
speaker output: 2W at 4ohm
PCB dimensions: 5.6" x 3.0"

Extra Info
   - Hints

If bark frequency is to low (very slow bark) reduce de value of C3 (ex. 1500pF).
If microphone is to sensitive, lower the value of R20 and increase the value of R2.
If there is a metallic background noise, put a 33pF capacitor from pin 7 of IC3 to ground.

CAR ALARM
 
The alarm detects sudden voltage drops of the battery when the interior, trunk, or hood lights are switched on. To ensure correct operation, a number of control indications have been included, such as : flashing LED to indicate that the alarm is in standby mode after a set time (after you have left the car). Pre-alarm (built-in buzzer) to indicate that the alarm is activated, so that you will not forget to switch it off.
