Building a great deck for typical Kiwi indoor-outdoor living is on every home-owner's list at some point. The deck we are building here is a fairly normal slatted timber deck less than one metre high. This article is an overview of general steps in building a deck and is intended as a broad illust...
In creating a fully automated target, with spring-back target buttons controlled by microprocessors, I was able to compare the workings of Arduino and PICAXE. Arduino and PICAXE are two very different devices—like comparing a revolver and a shotgun. There are smaller Arduinos and bigger PICAXE...
When designing a house, first build your giant shed where you can make joinery for the house-to-be. That was the thought of Julian Pirie. But he was to take a special route—he decided to model his barn-like “shed” on old-style English oak barns, typically housing Aston Martins in magazines p...
Without knowing electronics, it’s easy to tackle this small robot which demonstrates how a machine can be programmed to back off obstacles it hits. Mark Beckett helped to construct his daughter Hayley’s easy-to-make “HaloBOT” which is controlled by PICAXE. You can follow the building proce...
Restoring old motorbikes and cars is Dad’s passion. The garage is home to four of Dad’s prize beauties all lovingly semi-restored in various stages of TTI (Time Till Ignition). The projects in question are two cars: 1956 Wolseley 6/90 Series 1 and 1935 Hudson de Lux 8 (side-valve, straight-eig...
This project to make a stool was developed as a way of introducing students to a number of basic wood-bending and shaping techniques, whilst also giving experience in several useful applications of the router. The stool consists of two legs in the form of continuous steam-bent hoops or arches, whi...

The idea of the air-cooled mini-bike as a school project for Year 12 and Year 13 students has its roots in a reaction to the introduction of NCEA Technology back in 2002. Like many other technology teachers at the time I embraced the new curriculum, believing it was the right way forward for the future. How wrong I was.
There are so many types and kinds of bolts and screws that when you ask for the one you need, it is best if you understand the characteristics of the particular fastener. Then you can ask exactly for what you want.
This learn-by-doing school project engages many skills. The essentials of the fishing reel are the spool, the reel and the chassis, brace and clamp on which they sit. The process begins with the stub material rod cut to length and a 8 mm outside diameter thread cut into it. Two 0.8 mm deep grooves are turned into each end of the stub for the e-clips which will hold the reel in place.
Converting an ordinary van to a campervan is a project I have been talking about for some time. As a retired technical teacher, I felt I had the necessary skills and when a 2005 Kia Pregio van in excellent condition became available I decided to take the plunge.
In the second and final part of building a classic cabinetmaker's bench, we are making the tail vice. The concept behind the vice is a parallel box made up of four components that is driven along a series of guides and matching tongues and grooves by a single screw.
Over the last couple of years, my son Kurt and I have built a few basic go-karts which not only gave him a taste of very basic engineering, but also allowed us to pile up valuable hours of quality time working together in the shed. This new project is one-person off-roader that would suit a 12 to 13-year-old through to an adult. It is powered by a 300 cc quad engine.
