LED lantern (a project for youngsters)

Modeled on the hurricane lamps of old, this simple project employs a candle LED to produce a pleasant flickering glow within a housing based on a 500 mL (or similar) recycled plastic bottle – as commonly used to dispense spring water and fruit juice. It is an ideal project for youngsters, and the construction details […]

Two Dragsters

Electric Dragster project for line-racing

These electric dragsters are constructed from readily available materials – some recycled – and are intended for team racing along parallel guide lines (fishing line under tension is ideal). Cable-ties and electrical insulating tape hold most of the components together, with soldering only required to connect wire cables to the motors and switch. The Electric […]

Milk Carton Platforms for DIY projects

 Cardboard recycled from 1-litre milk cartons is excellent material for constructing mounting platforms, or base plates, for DIY projects. The Milk Carton Platforms document describes how to make two platforms, with dimensions 170 mm x 70 mm x 20 mm, from one clean milk carton. These 170 mm bases are used with our Franklin Bells project […]

Solar-1 (Total Solar Irradiance)

Solar-1 is a snippet – a small document that doesn’t fit into the kit or project category. The material in Solar-1 is an update of that presented in the first session of the Solar Energy for Electrotechnology professional development series. Solar-l follows the path of radiated energy from the Sun to the Earth’s surface. Along […]

Pump Station #4 – the best yet!

Pump Station #4 is simpler to construct than our earlier designs, and is also the most rugged of those using recycled milk-cartons for tanks and stands. The Pump Station #4 project document includes step-by-step assembly instructions and dimensioned sketches for all station components – including PUMP-3 (our latest and simplest pump design). Kits are also […]

PUMP-3 kit is now available

We have had requests for pump kits to provide teachers with sample parts to compare with the T-pieces, electrical conduit and nylon fixings they find at local suppliers – there is quite a variety out there. PUMP-3 is very easy to assemble. It uses an electrical T-piece to hold the motor and the conduit riser tube (John […]

Make your own Hover-Plate

From our recent Hovercraft Haka experience and feedback, we have edited and expanded the Hover-Plate project document – which can now be purchased and downloaded. The document addresses the construction, operation, performance testing and performance analysis of a simple model hovercraft. It details the DIY equipment used to measure air-cushion pressure, forward thrust and terminal speed, and […]
