Products - SARCNET

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.

This STEM kit will help you learn to solder electronic components to Plated Through Hole (PTH) Printed Circuit Boards (PCB). The kit comes with a 4cm x 6cm practice PCB, with 280 pads aligned in a grid, as well as 60 1/4W carbon resistors and 600mm of lead-free solder. The task is to solder 56 resistors in 4 even columns across the PCB. Note: The resistor leads should be insered into columns A&E, F&G, K&O, P&T. The first resistor is already soldered for you as an example. Make sure to follow all the safety instructions in our PTH Soldering Workshop Notes.

This simple kit will detect metal objects a few centimetres from the coil. It activates an LED and a Beeper. Adjust the potentiometer to set the sensitivity. Although the PCB says 3-5V it is more conveniently powered by a 9V battery. Download the instructions here.

For the more advanced constructor, and great as a project over the Christmas break, you can tackle this Mini Christmas Tree LED project. Powered by 3 AA cells, or from the USB port of your laptop, this multi-coloured display looks really fantastic on the mantle-piece at Christmas. Download the instructions here.

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.

Our Arduino microcontroller kits are perfect for anyone starting their own Arduino projects. Simply plug it in to a laptop and start coding. They include the following pre-assembled parts:

This is a complete soldering station for anyone wanting to learn Plated Through Hole (PTH) and Surface Mount Technology (SMT) soldering. It is safe to use provided you follow the simple directions. Eye protection, heat-resistant gloves and 100% adult supervision is required for absolute beginners. We use it to teach soldering to students as young as 5 years old. After one session they are proficient in the basics. They simply love building their own electronic circuits. It is perfect for building all our kits, of course, and better than larger and more expensive sets for most SMT work. It even runs off USB backup batteries for portable operation. Important: Before plugging the soldering iron in, please pull off (do not unscrew) the protective plastic cap! The kit includes:

We use these soldering irons because they work well and are perfect for beginners with small hands. They are suitable for building all of our kits and work particularly well with tiny surface mounted devices. With safety formost in our minds, when teaching children to solder, these devices work on low voltages, shutdown automatically and are quick to heat up and cool down. They can be powered by any USB phone-charger or even from laptop USB ports. Important: Before plugging the soldering iron in, please pull off (do not unscrew) the protective plastic cap!

This professional temperature-controlled soldering iron is perfect for more advanced projects requiring precise temperature control and additional power. It is suitable for both Plated Through Hole (PTH) and Surface Mount Technology (SMT) soldering. It has an LCD display showing the temperature setting and + (UP) and – (DOWN) temperature control buttons convieniently located on the handle. 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.
