what about uncle alf?

Letter of the MONTH I enjoy the articles in all of your magazines, and look forward to buying each issue. Regarding your article by Ritchie Wilson, Engines Enable Exploration (July–August 2020, Issue No. 91), in the section ‘The Hamilton jet is born’, Mr Wilson stated that “The breakthrough, which resulted in a much more effective propulsion system, was to have the jet of water squirting at the water surface rather than into the water below the surface. This idea was so successful that it allowed Bill to redirect his Christchurch-based engineering company away from its heavy-engineering work.” Nowhere in his article does it state who came up with the idea of squirting the water on top. The above passage leads the uninformed reader to believe that it was in fact Bill Hamilton. “Hamilton…

seize the day and train for free

Perhaps there is something you’ve always had a hankering to do but the cost of retraining or full-time study was too high, or perhaps you know school leavers or someone who needs to find a new career as a result of Covid impacts — if so, then read on. For anyone waiting for the right moment to commit to a new future, this is that moment! In July, the government announced a training initiative making technical training courses free, to support New Zealand’s recovery from the impacts of Covid-19. Several primary and secondary industries are short of qualified new entrants and, as Covid-19 is also causing many people to reassess their careers, the Targeted Training and Apprenticeships Fund (TTAF), developed in association with industry and training organizations, has been designed to help…

lancaster bomber blasts covid blues

For me, World War II technology hits the spot; ships and aircraft, in particular. They had massive battleships back then, and amazing aircraft that looked as if they were absolutely perfect for the job they were designed to do: readjust the thinking of the opposition with the absolute minimum of political correctness. These were not machines that formed working groups, discussion panels, or advisory committees; they just got on with it. Their crews did not have to take anything into consideration except delivering the message — and if it wasn’t entirely understood then another dose was delivered the next day. These ships and planes looked like real machinery, too — metal not carbon fibre — and they were never painted anything but grey. These things ran on steam or had V12 Merlins…

magic radio part 2

In the first part of this vintage upcycling project in Issue No. 92 of The Shed, I anticipated that it would become quite a complex project. For that reason I have divided it into several articles, to make it easier to build and understand. In part one we upcycled a Bush transistor radio, applying some radical changes. Thanks to the digital controller and the stepper motor added to the tuner, the radio can be programmed to indefinitely repeat a selected range of frequencies. In this second part, we will see how it is possible to take advantage of this new functionality to make some music. From receiver to musical instrument According to the connection scheme design, the upcycled device acts as the ‘instrument’. The next operations will be covered by a Raspberry Pi, with…

stamping ground

When Yağmur Habora was a fine-arts student in Izmir on Turkey’s Adriatic coast from 1998 to 2003, part of the curriculum was an introductory leatherwork class. Fast-forward to 2015, and Yağmur was employed at a failing Christchurch bar and restaurant. Before the inevitable closure Yağmur decided that she had had enough of hospitality and its stresses and set up her leatherworking workshop in the two front rooms of her 1920s bungalow. The north-facing bay window provides plenty of light and gives her a view of passers-by in the inner-city street. Leather working also allows her to work for herself and to practise a craft that has a long history in Australasia. It is a craft that she feels strongly is in danger of being lost and should be preserved. You meet the nicest…
