A bit of light work

The answer came like a light bulb. In fact, it was a light bulb – one that fits snugly under the top of the drill press and shines on the complete work area below, with little or no chance of casting unwanted shadows. It’s easy to make, as you can see from the step-by-step pictures.

Industrial style at home

For the centre, I had intended to use one-inch (25.4 mm) diameter stainless steel that I had left over from a previous job but the lamp we purchased came with a one-inch chrome-plated tube which I decided to use. It also came with a screwed insert in the top for attaching the lamp and this saved me from needing to make an insert.
If you use stock tube, you will need to make an insert to fit in the top of the tube to take the lamp you purchase. This could be a nut you can find with the same thread as the lamp and where you just need to have the outside diameter reduced or you can make an insert and thread it accordingly.

A home-made Kontiki built from scratch

Over the years I’ve tried sails, kites, giant bags, kayaks and surfboards to get hooks out where the fish are. After watching torpedos on the beach, I find it is now obvious that there really is only one way and it requires 12 volts and a motor.
Of course every challenge is only really about what you can learn in the process, so I set about building a kontiki torpedo and winch from scratch for as little as I could. I had to enlarge my capabilities especially in aluminium casting, plastics forming and in electronics.

Electronic, mini wooden Christmas trees

That original version of this project used 3 mm light-emitting diodes (LEDs) and no printed circuit board. Because of its size, it was tricky to wire and not so easy for a novice to construct. But the version of the project being followed here has been updated and adapted for easy construction.

Electric motorbike build

As a designer and motorcyclist, I had the idea of building an electric motorbike for a long time. The opportunity arose when I was in my final year of an honours degree in industrial design at Victoria University. I rode a 1987 Honda VFR400 to my lectures and the bike started having engine problems. I pulled out all combustion-related components and sold them. By the time I had a plan for an electric motorbike laid out I was part-way through a post-graduate diploma in Computer Aided Design (CAD) at Christchurch Polytechnic.

Secrets of amplification

Electronic amplifiers are widely used in almost all electronic equipment— they can either be a separate piece of equipment or an electrical circuit within another device. The ability to amplify is fundamental to modern electronics, where a small electrical signal is amplified into a larger output signal with increased power output or signal strength.

Let the sun run your pump

I suppose all waterfalls are solar- powered – the sunshine evaporates the water which turns into clouds, becoming rain which pours down into waterfalls. So the publisher’s challenge to make a small solar- powered pump for Greg’s sculpture seemed not too difficult.
