 | Light 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: $14.59

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: $34.49

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: $29.49

 | 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.

Music Box Engine, Light Activiated
Philmore DATAKit # 80-014
This circuit will play a tune when light strikes a light dependent resistor, such as when a music box lid is opened. You can select any one of about a dozen romantic melodies; play just one or let the unit cycle through all of the tunes. Operates on 3V DC, two AA cell holder included. You could really wow a girl friend or simply please your mom.Includes components, but picture shown without components. We suggest you also order a soldering tool kit to make this project.

 | Three 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). Click Here For Picture Of Soldering Kit # 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. We suggest you also order a soldering tool kit to make this project.

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

 | 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. We suggest you also order a soldering tool kit to make this project. Click here to go to this item (# S540). Click Here For Picture Of Soldering Kit # S540.

Two-LED Flasher Kit
Philmore Datak Kit 80-012
The Two-LED Flasher kit is a very basic kit and it does nothing more (or less) than blink one LED and then the other. The back and forth flashing is reminiscent of a railroad cross signal light, and many times it is used by model railroaders for that purpose. Simple bi-stable oscillator circuit; operates on 3 VDC and two AA cells, and will last for weeks. You can change out some of the components for faster or slower flashing rate. Details are included in the instructions. We suggest you also order a soldering tool kit to make this project. Click here to go to this item (# S540). Click Here For Picture Of Soldering Kit # S540.

 | 5 LED Sequential Flasher
Philmore DATAKit # 80-525
The circuit flashes five LED’s in sequence repeatedly until you turn it off. Flash rate is user adjustable. The circuit uses an IC chip-onboard which you will then mount on the included motherboard; battery holder is included. Powered by a 3 Volt supply or battery; good for a child’s toy or for those "high-tech" looking special effects for stage plays etc. Picture shows PC board used in kit. We suggest you also order a soldering tool kit to make this project. Click here to go to this item (# S540). Click Here For Picture Of Soldering Kit # S540.

5 LED Multi-Sequential Flasher
Philmore DATAKit # 80-375
Flashes five, very bright LED’s in any one of seven, user selectable, patterns. A COB (chip-on board) IC makes assembly very easy; the chip is supplied pre-mounted on its own board and a motherboard contains the entire circuit. Operates on 3 volts DC, battery holder is included. Continuously repeats a sequence when power is applied. Picture shows PC board used in kit. We suggest you also order a soldering tool kit to make this project. Click here to go to this item (# S540).
