School Amateur Radio Clubs have inspired a number of very interesting radio and electronics projects. We are developing more all the time. Some of our most popular projects have now been turned into products for sale in the hope they will encourage more youngsters into STEM through the development of School Amateur Radio Clubs. Of course we will always continue to offer free project information, software and support where we can. We have secured our website and we use the secure PayPal server. We aim to provide high quality hardware and software. Each of our products is fully checked and tested before shipment.

Please contact us for price (RRP. AU$15) and availability of our PTH LED Christmas Tree Kit.
STEM Kit #5 - SMT Electronic Dice Kit
This kit is an electronics touch dice. It works off a 9 volt battery. By just touching the two contacts on the front of the PCB with your finger, it sets the 7 LEDs in motion. They eventually slow down and stop flashing to reveal a random number from 1 to 6, displayed in the same pattern as used on a real dice. You can use this circuit with your favourite game of chance. See a clear overlay diagram here. Please contact us for price (RRP. AU$15) and availability of our SMT Electronic Dice Kit.

The temperature range is 180°C - 480°C with a fast heat up time from a powerful 80W ceramic heating element. It uses standard Hakko 900M tips and the tip is grounded for anti-static protection. Please contact us for price (RRP. AU$30) and availability of our LCD Soldering Iron.
Mini Morse Code Practice Set
This is one thing that really surprised us: Kids love Morse code. It fascinates them and they pick it up quickly. We used to do our Morse code activity with a Hi-Mound HK704 straight key and oscillator. But that setup costs over A$140, so we can't use it to do a class or group activity. The answer was to design our own Mini Morse Code Practice Set. And for A$10, it is a hit! Now, for the cost of coffee and a donut, kids can have their own set to take home. It comes with a microswitch, simulating a real telegraph key with a nice click-click action, a 2.5kHz sounder, a 3V lithium battery (CR2032) for up to 36 hours of continuous tone operation, all mounted on a double-sided PCB with a non-slip base. It measures only 64x36x15mm and fits in the palm of your hand. It comes in a zip-lock bag, with a laminated, credit-card size, Morse code chart and instructions.
- This product is only available for shipping to Australia and Worldwide in quantities of 20, lithium batteries not included.
- Other quanities, lithium batteries included, are available for only A$10 each, pick-up by prior arrangement only. Contact us to arrange pickup.

Satellite Antenna Rotator Controller and TRACker
SARCTRAC is a portable, integrated, satellite tracking system, which is now available as a fully assembled, tested and calibrated product. Simply mount it on your tripod; attach it to your hand-held satellite antenna using your counterbalanced lift-arm; connect it to your radio transceiver and battery; strap on the SARCTRAC 3D sensor to your antenna boom; then use your WiFi-enabled mobile device to control SARCTRAC and select the satellites you want to track. SARCTRAC will predict future satellite passes, track each satellite in turn and even tune you radio to the correct frequency for each overhead pass. With a SARCTRAC system and your own equipment you can listen to orbiting space beacons, make two-way satellite contacts and use free, third-party software to download earth images and decode satellite telemetry. It's both fun and educational! Note: SARCTRAC comes with its own test stand and a test lift-arm for demonstration purposes.
New for 2020: The Amateur Radio International Space Station (ARISS) team and NASA have installed a permanent radio repeater on board the ISS. So now you can use SARCTRAC to listen and talk to other Amateur Radio enthusiasts via the ISS!
