Your chance to add to the Henry Hoke legend!

‘The Lost Stories of Henry Hoke’ will be a unique opportunity to  share stories, myths and legends and even previously unseen Henry Hoke inventions.

From 1pm to 4.30pm on Saturday 28th May 2016, the Terowie Institute , Main St of Terowie South Australia, will host a gathering  of scholars, shed scientists and others who will focus their brilliant minds on the never ending story of Henry Hoke, our greatest inventor.

This official History Month event will only be a gold coin admission, which includes afternoon tea and a film screening. There will be special extremely rare prizes for the best stories and the best newly-discovered Henry Hoke invention, tool or device.

There will be a BBQ afterwards to aid the Terowie Citizens Association community-building efforts.

It is hoped that this will be one of the best displays of refined bulldust since Henry blew through the town years back.

Contact Mark Thomson via email or phone/text message (0419 865 821) if you are coming . We wouldn’t want to run out of cake and tea cups .

Apply your mighty imaginations to those stories and invention now!

Second prototype of Toroidal Ring Vortex machine undergoing trials

After years of scrabbling around in the back blocks of Australia’s farm ‘resource collections’ (i.e. the back paddock dump) a second Toroidal Ring Vortex machine has been discovered and is being restored.

Controversially, this is apparently a World War 11 German Wehrmacht machine known as a HF99. The HF apparently stands for Himmel Furz. Finding parts has been very tricky indeed especially something known as “die Klappe Foofer”. Any suggestions welcome.

If you do not know of the Toroidal Ring Vortex Machine, the video clip below shows one being operated by IBYS head chutney consultant Billie Justice Thomson.

Twittering Machine

Avian augury – the use of birds to foretell the future – has a fabulous history. Every morning I hear them telling me to get up and make the best of the day.
How to capture that indescribably beautiful sound of birds in the morning?

Short of superglueing some parrots to a fence, the avian research arm of IBYS has built a prototype that may be unveiled at the Science Week Fair in mid August…

The Shearing Days

Recent research work by IBYS associates has thrown more light on Australian Inventor Henry Hoke’s “missing years” which currently seem to be fairly elastic – they could have taken up most of his life.  Photos taken in a remote shearing shed prove definitively that Henry really did work in the shearing industry- these stencilled letters which spell out his name on the shearing shed wall are part of a longstanding tradition when a shearing season comes to an end. The exact year of the stencilling is unclear.

Henry Hoke was thought to have invented the now-common shearer’s pizzle guard.

Any stories or anecdotes about Henry’s experiences as a shearer are always welcome.


Here’s an interesting project!

We’re looking for participants in building a self-propelled bicycle merry-go-round.
I saw one at the San Francisco Maker Faire earlier this year and it was so obviously a heap of fun, I thought it would be great to build one.

I immediately thought of two things:

It’s a Hills Hoist! Americans don’t seem to be familiar with the Australian icon that is the rotary clothes hoist. In fact the whole idea of exhibiting one’s washing in the backyard seems to appal some US citizens, who pass neighbourhood laws banning it! But we love our Hills Hoists and many of us can recall swinging on them as kids (and busting them as a result).

Most rotary clothes lines are too small for adaptation like this and we may have to extend it slightly.

We should use all the energy to power something. We could attach a generator to the central axle and drive something electrical that would make more lights/music/interesting effects the faster we went around. Or we could drive something mechanical such as a pump, a fountain, a wind powered organ, you name it.

It’s not so different from a horse whim or a capstan which was used to power all sorts of things before steam came along: mining equipment, mills, ferries etc.

I’ve written to the people at Cyclecide in California to ask them if it’s alright to pinch the idea. Cyclecide are a bunch of ‘alter-bike mechanics and cycle crazed clowns’ who do brilliant things with bikes. Rudy, one of the big sprockets there, said go for it. So we should.

There a few considerations:

It will need to be reasonably safe and robust (we know from doing stuff for exhibitions that kids can destroy astonishing things) It will have to be reinforced as Rudy suggested there are big forces on the thing once it gets up speed with 5 or 6 adults . He also suggested getting an old car wheel as a bearing to go on the ground.

It should be dismantlable so that other people could use it at a later date.

We don’t really have any money so we are going to need to do a bit of scavenging. Luckily old bikes are everywhere and there’s heaps of old Hills Hoists about.

Judging from the line up of kids at Maker Faire it could be very popular.

If you’re interested in participating and live in the Adelaide region, please let me know.

Update late 2014: We struck problems with it here in SA due to very stringent (and ultimately costly) regulations around show ground rides, based on some tragic incidents at the Royal Show.
HOWEVER – this did end up getting built in Melbourne by my friends Liam Gerner and Autonomous Black under the name Backyard Carousel from some crap drawings I did. Good on you fellas! It still gets taken out and given a thrashing now and then.

Broken Hill String

I’ve been up in Broken Hill and surrounding areas recently working on the wire project – which is about all the resourceful ways that people use wire to repair, adapt, create.

I’ve been on the track of “Broken Hill String”, which is the wire used in the local mines to set off explosives. Once used it is discarded and taken home by the miners who find literally hundreds of uses for it. It is a sort of predecessor to cable ties. There’s a great sense of pride in local resourcefulness here and a slight annoyance from the older miners I spoke to about the general wastefulness of modern life. More to come soon. I’ve also been out into a few local pastoral properties looking at the way people use wire (usually a lot heavier gauge wire) to repair and make things. Some of the building techniques are clever.

Where’s the Henry Hoke exhibition?

The immense Henry Hoke tool collection is currently located in Canberra where it resides in the care of the Questacon, the national science and technology centre. The researchers there are giving intense thought as to the potential uses of the collection, which does include a partly constructed Quack of Doom and the only genuine functioning analogue Random Excuse Generator (well, it works sometimes).


As a result of the Question arrangements, we hope to see a whole new generation of young thinkers, scientists  engineers and makers wrestle with the brilliant mind of the great Henry.
