WORLDS SMALLEST FM RADIO?
This tiny radio has incredible sound. It has a SEEK button, ON/OFF, Volume control and RESET. If it isn't the worlds smallest it's close to it. The sharp, clear sound that comes out makes you think you have a jam box. This mini FM Radio is only 2.3" x 1.3" x .6". Comes with earphones and battery. Great to take with you to a ball game that is simultaneously broadcast.
DC VOLTAGE MONITOR
If battery status is important, you need this kit. This kit uses 7 LEDs to monitor 12v DC in 1v, 1/2v, or 1/4v steps. Monitor 8v or 5v in 1/4v steps. Great for boats, motor homes, model planes or race car ni-cads. All parts and instructions are included. SIZE: 1.3" x 2.7".
If you want to switch more power see our Triac Power Kit (TP-1).
AC VOLTAGE MONITOR
A must for photographers and computer users. Use it in your motor home to monitor the AC generator. The AC voltage is indicated in 6v steps by seven multi-colored LEDs. SIZE: 1.3" x 2.7".
If you want to switch more power see our Triac Power Kit (TP-1).
MICRO-MINIATURE WIRELESS MIKE
So small you could hide this one on some real bugs! It's the smallest we've ever seen. With its super sensitive mike it transmits a whisper or a room of conversation to an FM radio, tunable from 88 to 108MHz FM. With a proper antenna it transmits about 1/2 mle. The kit is made with surface mounted parts, we have already mounted these parts. You install the leaded parts. Power requirement 6 to 12v DC. SIZE: .35" x .9"
WIRELESS FM MICROPHONE
Small but mighty this little jewel will out perform most units many times its price. It really stomps out a signal Transmits up to 400 yards. The WM-1 kit is a buffered wireless mike that operates from 80MHz to 120MHz FM, the frequency of any broadcast FM radio. Includes a mini-electret mike. Power requirement 6 to 12v DC. SIZE: 1.25" x 1"
LIE DETECTOR
This kit can be great fun at parties. Lie and an audible tone will change, the more you lie the louder the tone. when you lie lie your hands sweat, this kit allows you to measure these changes, only a very slight amount of change will cause the tone to increase in frequency. Power requirement 6 to 12v DC. SIZE: .8" x 1.2"
RADAR SIGNAL DETECTOR
The RSD-1 kit won't replace a $200.00 unit but this simple yet effective detector circuit can be built in less than an hour and can be tuned to respond to signals from 50MHz to 500GHz. We supply a lighter plug. Power requirement 9 to 15v DC. SIZE: 1.75" x 1"
CAR THIEF FOOLER
Completely built, ready to mount
The important part is the red flashing light on the dash. This built up module has a red flashing light that will scare most thiefs away. Mount in a box or mount permanently in the dash. Operates off of the vehicles battery, draws about 15mA. SIZE: .75" x 1"
ELECTRONIC TIMER
Use this kit in A-STABLE (continuous train of pulses) or in the MONO - STABLE (triggered time delay). Times circuits from nano-sec. to 30 min. Comes with a variety of resistors and capacitors suitable for most applications. Power requirement 4.5 to 12V DC. SIZE: .9" x 1"
If you want to switch more power see our Triac Power Kit (TP-1) or Relay Power kit (RP-1).
ELECTRONIC TIMER
Same as kit ET-1 but has computer aided software to determine values of resistors and caps for time intervals. If you want to switch more power see our Triac Power Kit (TP-1) or Relay Power kit (RP-1).
INFRARED
TRANSMITTER and
RECEIVER

This kit transmits a 40KHz modulated I-R signal to a distance of 6 to 8 feet. Place the transmitter on one side of a doorway and the receiver on the other side to see if on object passes through. Can be used as a remote switch to turn objects OFF and ON by infrared. The IR receiver will only receive 40KHz modulated infrared light. You can configure the output for normally ON or normally OFF operation. This allows you to use it as a security sensor or as a remote control switch. You can use the receiver to test TV or VCR remote controls. If you want to switch more power see our Triac Power Kit (TP-1) or Relay Power kit (RP-1).
Transmitter SIZE: 1" x .75"
Receiver SIZE: 1.4" x 1.2"
LIGHT GENIE
Turn anything on or off with light. Turns on at night off at daylight automatically. As the light touches or leaves the sensor it delivers 100mA of output to run a relay. SIZE: 1.5" x 1.2" Power requirement 6 to 15V DC. If you want to switch more power see our Triac Power Kit (TP-1) or Relay Power kit (RP-1).
TEMPERATURE GENIE
Ever lost frozen food because your freezer stopped? The TC-2 kit would have saved you money. An alarm activates when the temperature reaches a critical point. Turn ceiling fans on automatically when it gets too hot. This kit gives you 100mA of output. SIZE: 2" x 1.4" Power requirement 6 to 15V DC. If you want to switch more power see our Triac Power Kit (TP-1) or Relay Power kit (RP-1).
