When it rains, build a geodesic dome

With rain on the way and a party imminent, did what anyone would do: build the geodesic dome and cover it with a Jeep parachute. Bonus of the parachute is it has Kevlar ropes that are very bounce-free.

The dome. Just going around and tightening it up.

Putting the parachute on top. Worked quite well as a rain cover. Played a bunch of games inside.

This is what the metal bars were. The shape is a general Level 2 isosphere that you may recognize from a soccer ball. 3 lengths of bars, clamp the ends, drill, and paint. Took about 3 hours to make with 3 people. If anyone is interested in the designs, just ask!

Biohacking Redux

Hello,

I am Rain. The current resident neurohacker/biohacker at ‘The Haus’.

You may know me from such past speeches as:

If you have an interest in chatting about biohacking, working on biohacking projects or just interested in finding out more about the subject in general then you should come join me at open|haus. We throw open our doors to the public every Tueday @ 7pm.

I have been working on a project to use an ‘off the shelf’ product with heart-rate pacing to help with recovery of chronic fatigue and over-training in athletes. I promise to keep you updated with my progress.

Plasma, the fourth state of matter

Plasma cutter. Cut 3/8″ sheet aluminum. Cut steel. Cut stainless. Be like the laser cutter, but for metal. That is the goal. But baby steps before we get to the whole thing though. Have to use the tools at hand to make the setup. As Think|Haus has 3D printers and laser cutters, making metal is a little different. The X and Y are done, now the Z. Here it is modeled on OnShape. It is a free, in-browser CAD software so that anyone at ThinkHaus can get it. If someone needs a key, ask, or look on the website. I am thinking of running a course on how to use OnShape soon. Website is here cad.onshape.com

Next, getting the metal. Must say, the selection that I have scavenged from the University is not that good and we don’t have a chop saw. Took a bit to cut two blocks from it.

Next I turned the blocks to size. Turned? Yes, we don’t have the collets for the mill yet. Turned. Worked quite well to be honest. Would be better if we had a 4 jaw chuck though.

DSCN8133

Bored out the holes and made a cut on the one side. Cleaned that up with a file. Afterwards I cut it with the hack saw again.

DSCN8137DSCN8138

Then put it all together and see how it looks.

DSCN8139DSCN8143

Next I need to make the mounts for the linear bearings. Will follow the same process again and hopefully won’t take a whole afternoon. I know it will though. All in the name of plasma.

What is that thing?

You may have noticed, or may have been present when a thing entered ThinkHaus last week. It is a pile of metal. Well, yes, it is, but it has some really neat capabilities.

DSCN8086

The machine was designed to accurately place fluid into test tubes. A gantry moved across the top and eight individual arms lowered to a different height. The test tube would then dispense liquid into a vial and continue on. There are fiber optics that were used to measure the meniscus of the tube, there is a 40″ and a 20″ long encoder. There are massive motors. There are 8 precision fluid injectors. There are lots of capabilites that can be made from this.

The most solid idea so far? A plasma cutter.

Zeeshan has a plasma cutter at home he bought to use for cutting metal to add to his arsenal of home built CNC machines. With this, Think|Haus could cut metal. It requires 20A220V, so it would need a new setup akin to the kiln. Debates are still up in the air about how to do this, but there is an idea.

As well, I did mention 40″ and 20″ encoders. There are also 8 rotary encoders. There is more than enough here to turn the mill lathe into CNC.

 

In other news, I have been working on my own design of 3D printer. It has an environmental chamber to keep the temperature of the parts constant during printing.

DSCN8088

Also found this. This is a neat little thing that was part of the big machine above. It has hot/cold plates that can accurately set the temperature of test tubes or the test plate to 4-65C. It cools and heats depending on what you want! This will likely be given to a makerspace with biological use unless there is a keen reason to keep it here. The plugs on it must have been worth a fair amount.

DSCN8087

 

Finally, someone asked about a parasitic pump. If you need one, I can get it. Laboratory grade too.

Amplifiers are not supposed to look like that

DSCN8025 DSCN8026

Fixing taking apart an amp from the E-Waste. Noticed a fuse was blown, found a new one, and checked the resistance. 2 ohms seemed a little low. Looking deeper, the base speaker amplifier pair looked a little off. Burned right through with a chunk gone. Glad the fuse was there.

DSCN8029

Beast of a 5 amp 120V to +-17V center tap 15A per line torodial transformer in there. Likely going to turn that into another amp or something.

DSCN8027

The amp and its board. I may turn it into a speaker box and extract the power supply or replace the amplifiers. I have some amplifier chips here that should do the trick, but why they blew is likely more important.

Do you want to make a dinosaur?

We have wood. And a laser cutter. And designs. Here are the files, go and cut a dinosaur! Takes about 45 minutest to cut out, but drop a line and stop by! Three dinosaurs are here ready to cut. I sent them as a Secret Santa gift (pic shown) and they have been just sitting on my computer. Want to make one?

Updates At ThinkHaus

The mill is moving!

DSCN8010DSCN8017

The gearbox is fixed. The mill motor can be wired up and works. The collet was removed and opened. As well, a source of more collets was found and we may be able to get a whole set. All that is needed now is a box to put the motor capacitor in and a vice to clamp to the ways.

The kiln is very nearly done!

DSCN8018DSCN8019

The wiring is done shy of the two heating elements that will be purchased from The Pottery Supply House and a sheet metal plate to cover the back. Now, moving forward a shed will need to be built and discussions with insurance will be needed, but it is very nearly done.

As for the stilts, the clips have not come. They were supposed to arrive by Friday…. And that was the second time I ordered them…. Anyways, they will sit/stand waiting.

Signal Boost: Hamilton Mini Maker Faire

Maker Market Banner 2
Maker Faire is happening in Hamilton!

On June 21st, come to the Hamilton Museum of Steam & Technology.

See all the knowledge and mad creativity Hamilton has to offer.

The Museum is even going to open the 1913 Building for the first time, just for this event.

Think|haus is going to be there; you should be there too.
