Warning: boiling point!

25 May 2023

I own an American classic car and it comes with the usual 1960s instrumentation—speedo, fuel gauge but only warning lights for oil, alternator, and water temperature. The alternator light comes on when you turn on the ignition, but the water temperature light is designed to come on only when the water temperature reaches 120-125 °C which is usually too late.
To fix that, I have devised this program powered by an Arduino micro-controller that will operate the temperature light when the engine powers up and light it up again to warn the driver as the temperature approaches 100 °C. It uses a readily available sender that will fit most vehicles.

Arduino software for wipers and temp gauge projects

25 May 2023

Controller
I chose to use a shield (add-on board) to house all the parts for this project that allows the use of any standard Arduino and settled on a Seeeduino V3.0 and a Freetronics prototype shield as an inexpensive solution.
I used the controller and shield to for the previous variable wiper speed project for the car (“Wipe that classic windscreen,” Shed, Apr/May 2012). This second part uses the same controller and shield to do both tasks. The reader can either make one or both. The shield construction includes the extra parts (two resistors, one transistor, and one diode) and uses the “Start” button to do the “Normal” calibration.
Here are the two sketches (software) in these The Shed website’s two posts.

one combining water temperature light and variable wiper functions into one controller; and
one that just does the water temperature light.

Wipe, wipe that classic windscreen

19 May 2023

I own an American classic car and there are a few mod cons that are missing. I’ve added central locking because crawling over seats was a pain, but I thought the Arduino could add a few features that aren’t available in the shops. This is the first of two parts which uses the same piece of Arduino hardware to do two different tasks—run variable-speed wipers and a temperature gauge. Each can be used on their own as it makes no difference to the software

This offroader project is a beaut

23 February 2023

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 had a bit of a twist to it as, this time, my son was the chief designer and engineer and I was relegated to labourer. Like all the previous projects, he let me fund it.

Videos of metal shaping and motorbike guru, Steve Roberts

17 November 2022

In the November/December issue 105 of The Shed, our cover story is on a Kiwi legend of metal shaping and motorbikes, Steve Roberts.
If you enjoyed that article here is a link to a website that has even more of Steve’s story as well as videos of the cars and bikes he has constructed and inside info from chats with Steve.

Assorted nuts

2 June 2022

For our purposes, a nut is an internally threaded part which is rotated or screwed onto an externally threaded part such as a screw, bolt or stud. If you can pick it up in your hand and put it onto an externally threaded item and tighten it, it is a nut. There will be some exceptions to this which will become apparent.

Making your own campervan

7 April 2022

Converting an ordinary van into 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.
The van is a 2.7 litre diesel, manual, with 26,000 km on the clock and a cargo space of 2.8 metres x 1.65 metres. My plan was to fit the space with two beds, one on each side. They can be expanded to a full-width bed using the foam backs of the seats supported on shortboards between the sides of the seats.

Unpublished photos from The Shed Issue 93 – Tempero Motor Body Builders

29 September 2021

In The Shed Issue 93, we visited Tempero motor body builders in Timaru where we left in awe of the workmanship and skills we witnessed. Here are scores more photos from our visit that we couldn’t squeeze onto our pages that are just too good to be left unseen by readers.

A night at the speedway

9 December 2020

The allusion to knights and jousting is apt. Like knights in armour, the drivers especially of the sprint cars have very restricted vision. They can peer through the grille in front and can see a bit to the left but their right-hand vision is blocked by a wing and within the confines of the cockpit—with helmet and neck brace in place—they have very little opportunity to turn their heads. To make things worse, other cars are flinging up dust and mud that also helps to clog their vision.

Polish query ‘Autosolved’

4 November 2020

If you haven’t heard of Autosol, you can thank us later.
This revolutionary, ammonia-free product is the go-to cleaner and polish for uncoated aluminium surfaces. It leaves a clean sheen without scratching or hazing. The distributors say users describe it as “a product that does everything the advertising says it does”, “my go-to polish for aluminium”, and “perfect for alloy wheel rejuvenation”. It is available in a 75ml tube with screw caps from automotive, engineering, and hardware stores across New Zealand.

Spotless shine

14 September 2020

Polishing metal isn’t a task for which you want to be ill-equipped, especially when you’re chasing that perfect shiny finish! That is why Autosol has been the most trusted name since forever. The new Autosol 3in1 for Stainless Steel is specially developed to clean, protect, and leave a shiny streak-free finish on stainless steel surfaces — with anti-fingerprint effect.

Make a simple toy truck

28 July 2020

With toys, in particular, maintenance and reparability are important to ensure a long life. A broken plastic toy goes in the bin, whereas a well-designed wooden toy can make many trips to the repair shop over generations of play.

Make a camper trailer

9 July 2020

American teardrops first became common in the 1930s after DIY magazines such as Popular Mechanics published plans to build your own. The ultra-lightweight concept normally only sleeps a maximum of two adults in the cabin and has a small outside galley or kitchen at the back of the trailer. Often these campers weighed little more than 450kg and were very streamlined so were ideal for towing behind small cars or for long road trips.

The Shed July/August 2020 Issue 91, on sale now

15 June 2020

The July/August 2020 issue of The Shed, No. 91, has got something in it for every sheddie.
Even though there is something of a nautical theme to this issue, our cover story is on building a very powerful, vertical, hydraulic log splitter. Bill Stevenson from Christchurch walks us through the construction of his trailer-mounted log-splitting machine that was started prior to the Covid-19 lockdown, worked on during, and completed immediately after. A great effort.

Video of Cowper Trucks from The Shed Issue 90

26 May 2020

In this issue of the magazine we featured the trucks and workshop of Dan Cowper of Cowper Trucks in his shed just outside Whanganui.
Check out this video where Dan gives us the background to his business and how he builds his go anywhere, do anything, V8-powered, 4×4 vehicles.
