K43 Kit 43 Relay Board for 10A/250V Rated Relay

 



$15.62

K45 Relay Board for 2 x 1A Miniature Relays

Quite often the hobbyist needs to use a relay. The output of some device like a PIR has output pads for the alarm signal which must be connected to a remote switching device. Or sometimes we have a Kit to test which needs a relay connected to it. To fill these needs we have made two Kits which are just a relay, PCB and terminal blocks for the input/output signals. There are many relay pin-outs & drive voltages to select from. We have standardized on two 12V relays from Goodsky. Kit 43 uses a large electro-mechanical relay designed to switch 240VAC/10A. Kit 45 uses two miniature 1A relays.



$29.00

K49 Kit 49 Crystal Locked Ultrasonic Movement Detector 2

Our first ultrasonic movement detector - Kit 20 - has been very popular. This is another circuit design which we believe is more sensitive with fewer components. The transducers are mounted on the same PCB as the circuit.

K66 Kit 66 Peltier Module

We are selling one type of module 4cm x 4cm, (1.6" x 1.6") with 127 p-n couples. When current passes through two different conductors, heat is produced in one and absorbed in the other. Peltier first described this in 1834. Modern semiconductor materials can make p-n junctions which produce large temperature differences. This 4cm x 4cm x 4mm thick module contains 127 p-n junctions connected electrically in series but thermally in parallel. Maximum temperature difference = 59 deg C at 30 deg C ambient with no heat load. Maximum ratings = 13.5V, 4.4A, 36W.

 

 



$71.00

K72 Kit 72 Three x 8 Channel IR Transmitter & Receiver

Control 8 relays using this IR Remote Control Unit. Over 20 meters in sunlight. Uses 2 high-powered IR LED's & latest IR detector/decoder from Kodenshi. Transmitter case, 8 miniature relays & all components provided. Uses paired encoder/decoder IC pair. Full instructions included. Four ranges set by jumpers.

NOTE: Nov 96. We have found that the latest batches of the SM5032B receiver decoder IC (date coded 9620 & 9630) do NOT work as the previous chips did. The problem has been traced to a change by the chip manufacturer. The two jumper-on option does not work. No jumpers on or only one jumper on still works OK. So this is now a 3 x 8 Channel IR Tx/Rx. The manufacturer says they will not be changing the chip at the moment.

Specification sheet for the IR Receiver Module.

K74 Kit 74 PC Printer Port Relay Board

Do you have an old PC lying around the house which absolutely no one wants? Then you can convert it into a dedicated controller. Communicate with the real world via the parallel printer port on your PC. Simply connect printer cable from computer to Centronics connector on relay board. There are 8 relays each capable of switching 12VDC/10A or 240VAC/5A. Each relay has an LED to indicate when it is operated. We provide two sets of complete, stand-alone software to control the relays: one works under DOS so you can write your own batch files to control individual relays, the other under Windows 3.1.

Linux software for Kit 74 has been written by James Cameron. You may get it at Quozl's Open Source Work.

K79 Kit 79 Three Circuits-In-One LDR Circuits

We provide 3 complete and separate Light/Dark LDR circuits each with a relay on-board all in the one kit. Each is a simple well tried circuit: one uses two transistors in a super-darlington setup, the second uses a LM741 op-amp while the third uses a Schmidt Trigger. Each board has a PCB-mounted switch to convert the circuit from light to dark switching and vice versa. There is nothing original in these circuits - they have been around for years. What we have done is bring three good timer circuits together all in the one Kit for you to build & experiment with.



$20.52

K84 Kit 84 Mains Power Relay Switch

Many electronic projects use a low-voltage circuit to control the mains power supply eg. a touch switch, movement detectors, etc. In most cases the signal is brought out to a pad or terminal on the PCB. It is left up to the user to "use a suitable relay" to make the actual connection to the mains. Well this kit is the answer. It will take a +12V high or low going signal to switch a DPDT relay rated at 5A/240V. Both sides of the mains supply can be switched. A 5A fuse on one side is also included.



$26.00

K92 Kit 92 IR Remote Control & Decoder IC

This Kit uses a commercial 14 button remote control, unit to put an active low signal onto one of 14 output pins on a decoder IC. That is, when a button is pressed the pin corresponding to that button goes low. Normally, each of the 14 output pins is high. It is up to the user to use this information in their own circuit where remote control is required. For example, to control up to 14 relays or to control the movement of a robot. We supply all the necessary extra components required for the decoder IC to function properly. No PCB is supplied. It is up to the user to breadboard their application then make their own PCB. A sample application/test circuit is provided. A 330W resistor & LED are supplied for testing the active low on a pin in response to a button press.

We supply three sets of components:

K145 Kit 145 Serial Temperature Sensor.

Kit 145 is a PC controlled 4 channel temperature meter (either deg C or F) using the serial port,a PIC12C509 and 4 x DS1820. No external power required. We think that each DS1820 may be located over 200 meters away from the motherboard and PC. This is an ideal use for old 386 and 486 computers: continuous temperature data logging. Users will have to massage the input data stream to their purpose. It may be dumped into an Excel spreadsheet, or they can write BASIC programs using the INPUT command to grab the readings. As you can see from the photo there is not much to the hardware. (Developed by James Cameron and you can read his documentation here.)

The kit is supplied with one DS1820 due to their cost. You may buy additional ones to complete the kit directly from us at $US6.50 each includes airmail postage.

Note that the DS1820 has now been replaced by theDS18S20 (1/2000).

Kit 168 the Ultrasonic Wind Speed Meter

All the components fit under the 16 x 2 LCD. Switches S2 and S3 come out from the bottom of the board which has plastic 10mm standoffs. It uses a 40kHz ultrasonic Tx/Rx pair to detect wind speed. This design was published in EPE, 1/2003. A copy of the original EPE article goes with the kit. To hold the ultrasonics I found that the locally available, disposable chopsticks were excellent. They even had a groove to align the units to directly face each other. 

Here are the redrawn schematics - jpg. I have kept the same component designators as the original article.

K171 250mW POWER AMPLIFIER

This project is a simple 2-transistor VHF power amplifier,
with about 16dB gain, and requires no tuning or
alignment procedures. Wideband techniques have been
used in the design and the circuit is equipped with a "lowpass"
filter to ensure good output spectral purity. The
project has been designed for assembly on a single-sided
printed circuit board. The circuit is specifically designed
to amplify the output of 7mW to 10mW WBFM
transmitters (wide band) to a final level of 250mW to
300mW, after the filter.

DC to Pulse Width Modulator-K8004

This control circuit is ideal for the accurate control of DC motors, lighting levels, small heaters as well as other applications. The circuit converts a DC voltage into a series of pulses, such that the pulse duration is directly proportional to the value of the DC voltage. The great advantage of such a circuit is that almost no power is lost in the control circuit. Protected against overload and short circuit.
