Touch Switch with Relay Kit
(
Click on photo for larger view)

The Touch switch may be used to turn on almost anything with a light touch of ‘plate’. The circuit pulls in a relay which remains engaged for anything from five seconds to about a full minute, depending upon you changing just one resistor to set the time amount (default is five seconds). One of the unique features of this circuit is that the touch-plate may be located up to several yards away from the circuit board if necessary. It may also be battery powered if an AC supply is not convenient. An LM555 is used in the heart of the circuit. The relay can handle up to 12A in its contacts. A 12V battery pack or AC power supply is recommended although we’ve used the circuit on an unregulated 9V supply.

110 Volt AC Strobe Light Kit

Usually more practical than 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 on airplanes. AC cord and plug not included. (Beginners should be supervised when working with house current.)

High Accuracy Multi-MODE TIMER
(Click on photo for larger view)

Using a programmable IC, the circuit revolutionizes timers in terms of flexibility and accuracy. A number of triggering options are available, ranging from tripping a switch or a relay. Output relay is capable of handling up to ten amps. Time delay is easily selected (and accurately) with on-board dip switches. May be programmed from seconds up to 42 hours. Turn something on or off; seven different timing modes available to the user. The heart of the circuit is an ATMEL 89C2051 IC, already preprogrammed for you. A versatile circuit may be used to open the relay after a time period, close the relay or even toggle the relay on for a time and off for that same amount of time (toggling).

Serial Port Temperature Data Logger (Click on photo for larger view)

An 8 pin microcontroller based circuit for temperature data logging via the serial port or any PC; a good way to put that old 386 or 486 to work! Uses the Dallas Semiconductor DS1820 sensor (one supplied, will handle up to four). Assemble for either "C" or "F" temperature scales. Sensors may be located remotely, up to 200 yards. away from the PC. System provides real-time data via the serial port. Accuracy to .5o C. No external power is required. The data stream is easily logged and processed. You must use a terminal program set at 2400 baud, 8 bits, no parity and 1 or 2 stop bits. Information is given about a free Term.exe program that you can download from our associates web site.

40 Second Message Recorder with Looping Option.        
  (Click on photo for larger view)

The circuit uses an information Storage Devices Corp. No. ISD2540 chip to store one or more audio/voice messages up to forty seconds (maximum time). If desired, the first message can be looped so that it plays repeatedly. Non-volatile; the messages) is/are retained even when the power is removed. Output is to a User- supplied four or eight ohm speaker. The output is small, you may wish to add an LM386 amplifier kit (No. 80- 70) or another amp to increase the volume for your application. The same circuit could be used with any of the ISD25xx chips in the series up to 120 seconds record time. Operates on 6 volts at 100mAmaximum.

6-12 Volt Alarm Module or SCREAMER
  
(Click on photo for larger view)

The loudest piezo alarm that you will find: 108 to 110dB output (at) 1 meter. The kit includes a resonant cavity mounting case which is molded plastic, 2" x 3-1/4" and 1- 1/4" deep, plus mounting ears. If you want to totally startle a burglar, this is the kit to assemble. Operates on 6 to 12 volts. You’ll need a good supply: it draws about 500 mA maximum.

No. 80-150 Alarm Module Screamer.

4-digit "PRESETTABLE" DOWN COUNTER  
                                                                                                                   (Click on photo for larger view)

Set a quantity, up to 9,999 and count down to zero. The inputs can be a relay, switch or something more sophisticated such as an optical counter. The circuit could be used to count small parts. You could count persons entering a theatre or other building . When ‘zero’ is reached, you have options as to how the circuit will react. It can trigger a relay or simply cycle back to the present number etc.; perhaps you want a light to come on or a hopper to stop feeding parts. A theme park may not want an event to occur until a certain number of persons has entered an area. The fastest count rate is about 30 counts per second. A debounce circuit eliminates switch/relay input problems, that make other circuits less reliable. Operates on 9 to 12 V DC and current runs between 20mA and 40mA depending upon the displayed digits. A 150mA (small) 12 volt AC wall adapter works fine. Documentation is thorough, explains options etc.
