Light AlarmLight Alarm
Philmore DATAKit 80-080

A sensitive photo Darlington transistor is used with CMOS nand gate. The circuit detects light and triggers a siren.You could add your own triac or relay and switch practically anything.

The kit uses the MEL12 Darlington superalpha phototransistors, typically about ten times more sensitive than a normal phototransistor. The circuit usage includes burglar alarms, medicine cabinet alarm, automobile alarm etc...  


Price:  $22.96 


PIR Motion Detector
Philmore DATAKit 80-300

One of our favorite circuits. The circuit sees infrared heat, such as from intruders body. The kit uses a late development in movement IC’s and employs a very sophisticated circuit. You may set it to non-trigger in daylight hours. When tripped, an LED indicator lights and relay is tripped. "Sees" up to about eighteen feet. Operation on 9 to 12 volt battery with very long life.  


Price:  $41.70 

PIR Motion Detector


Strobe Light Kit 110VAC Strobe Light Kit 110VAC
Philmore DATAKit 80-140

Usually more practical then a battery operated strobe, runs on standard house current. The flash rate is adjustable from about one every three seconds to about three per second,

Uses are as signal beacon, trade show kiosks, discos, etc.. Very bright flash can be seen for miles at night, Like those in airplanes. AC cord and plug not included.

 


Price:  $39.34 


Infrared Toggle Switch
Philmore DATAKit 80-580

Control about any device using the remote control from just about any TV set. The circuit switches an on-board SPDT relay, turn it on with the remote and turn it off with another signal.

The relay contacts are rated one amp at 125 volts AC. The circuit operates on any DC supply from 8 to 15 volts, use an old calculator supply etc.. This circuit can have some very practical applications such as turning on a light by an invalid.

Your imagination is the limit.

Infrared Toggle Switch


Three Light/Dark Activated Relay SwitchesThree Light/Dark Activated Relay Switches
Philmore DATAKit 80-790

This kit is one of our three separate circuits in one; three separate PC boards etc.. This one will give you both useful circuits and experience in different approaches, circuit-wise, to doing the same thing; controlling a device with a change to either light or darkness.

Each kit is equipped with a relay rated up to 240VAC @ 5 Amps. You may either turn "on" or turn "off" the controlled device. A good kit for the student learning electronics.

We suggest you also order a soldering tool kit to make this project. Click here to go to this item (# S540).

Photo Sensor with Control Relay
Philmore DATAKit 80-103

The most popular usage for this kit is to make your own nightlight; and you won't be limited to one of those dinky seven watt bulbs. You could also switch just about any appliance, either on or off, with either darkness or daylight.

Light sensitivity is adjustable over quite a range. The relay can handle up to 10 amps AC. You need to add a nine volt transistor battery or a nine volt, 25 mA or greater power supply.

Photo Sensor with Control Relay


Fiber Optic Audio LinkFiber Optic Audio Link
Philmore DATAKit 80-260

Uses a matched transmitter/ receiver pair from Motorola or Industrial Fiber Optics Co. Allows you to send sound through plastic 1mm fiber optic cable.

Two circuit boards with a microphone at one end and a speaker at the other; (14’ fiber optic cable included). The maximum range is about 220 yards. This can be a Science Fair winner.

Picture shows board without components mounted.

Infrared Beam Door Minder
Philmore DATAKit 80-013

A transmitter sends an I/R beam up to 75 feet to a receiver (on separate pc boards); break the beam and a relay is tripped. Use the relay to control a bell or light or other device ; even a video recorder and camera.

Operation requires 9 to 12 VDC, a wall adaptor is fine and you may want two units (provision is made to power both boards with one supply via a two conductor wire). Use to watch a hallway or drive way, across the doors to a three or four car garage etc. and we know of a photographer taking wildlife photos this way.

The uses for alarms, photography, door minding and so on are numerous. You could make weatherproof hoods to use out-of-doors but be sure to protect from moisture.
