diy aquaponics automation | Stirling Engines My second attempt

diy aquaponics automation

I think I may have actually built something.

Or nearly built something.

It looks like this and almost works.

Most of that junk in the picture isnt part of it. The bits that are part of it are the bits that look like a Stirling engine.

Sometimes Stirling engines look like tin cans, and wire, and pink balloons. They also look like cardboard disks with blu-tac stuck weights all over the place to act as a flywheel.



I planned on posting a video of it working today, but it doesnt.

What it does do is spin around freely for a few seconds when you spin the flywheel. It also has a displacer and power piston that are configured in such a way as to do what they are meant to.

I think.

When I put it on the stove top, it nearly feels a bit like its trying to work, then smoke starts pouring out of the seals, so I take it off the heat before it catches fire.

Who knew tape might burn.

Yes. Thats right. I thought Id make my engine using gaffer tape for the seals.

It doesnt work so well.

Tomorrow, Ill buy some glue. I seem to remember hearing of someone who used two part epoxy on a real engine crankcase, so it should cope with the heat.

Maybe.

My next choice will be solder. Solder melts when you get it hot, so Im guessing that wont work so well either.

But the glue might.

If it works, Ill put up a big build post. If it doesnt Ill try something different.




120 Things in 20 years - Using a random evolutionary approach to building a Stirling engine. Chuck some bits in a bag, shake, then cull anything that doesnt work like a Stirling engine. Ill get there eventually.


[edit from the future - For anyone concerned that time may not be linear any more, this post was actually written two days ago, but for some reason didnt get posted. As a result the post after this one was actually two days after this one.]

diy aquaponics in agriculture | Winner! Attempt

diy aquaponics in agriculture

I totally didnt win a 3D printer!

Sad face.

I really wanted to win a 3D printer.

But I guess everyone else did as well.

Oh well.

I actually voted for someone else.

Perhaps that was the problem.

This really cool barometer entry featured a glass jar with a balloon glued over the top, and a stick glued on top of that so that, when you place the device next to a wall, the stick would move up or down depending on the air pressure of the day.

Very cool.

Very minimalist.

Anyway, Ill just use my 2D printer, but Ill print a lot of copies so I gain some depth.

Or figure out a different way to win a 3D printer.

Or maybe just become a patissier.

Either way, its all good.

Perhaps I should have posted a link to vote for my entry or something.

easy diy aquaponics.com | This Years Balcony Garden attempt!

easy diy aquaponics.com

Good crop of tomatoes, no aphids since i planted lots of onions and marigolds, Blackberry bush has grown huge and still growing had to use an old clothes drying rack as a growing frame, Installed a new drip irrigation all the way around balcony from my 100liter water tank with the help from my grandson.
Biggest obstacle has been getting supplies to my apartment, carrying bags of growing mix and compost by bus is a pain to say the least, oh well at least its exercise. I am lucky with that i get 6 hours plus of sun on the balcony, but the winds can be a destroyer drying things out and breaking my tomatoes.

diy aquaponics cheap | Worm Farm

diy aquaponics cheap

I went to a compost and worm farm community talk and class, anyway it was very informative and got to watch the worm farm put together.
at the end there was a raffle for 2 worm farms.
I am now the proud owner of 1 of them.
it was my intention to make one out of recycled stuff , but hey whose complaining.

The class given by Steve Batley of Sydney Organic Gardens

The new Worm farm tower

Far right! The base with legs, and tap, 1st tray, 2nd tray, and lid

2 composting bins, will only use one , as it fills up with worm castings will start using 2nd one, the worms make their own way up.

the first bin is filled with a peat coconut coir soaked in water till its expanded, not wet just damp, place cardboard at bottom of 1 tray to stop the dirt falling threw, spread the mix and add the worms , cover with damp news paper. the brown bag was just  temporary added at the class!

The first tray is placed in the bottom of the tower where the worm tea will collect and the tap for harvesting.

add the 2nd tray but will remain unused for time being.

Place the lid on

You dont feed the worms for the first week, just cover with damp paper, then slowly add the scraps of food under the paper, there is no smell, but if you add more than the worms can eat at one time this will rot and start to smell, or if it gets to wet! so dont over feed or make too wet!

also add some bits of card paper with the food to keep a good consistency.

DONT: feed meat, fish or dairy products, (egg shells are ok) or onion or garlic.

It will take about 3/4 months before 1st bin is full and can spread the castings in the garden or in my case on my planter boxes, the worm tea can also be diluted and used as a plant growing tonic.

It will also provide additional food to feed the fish and chooks they will love the worms!!

As my worm farm only came with a sample worm set up, i went to a local garden center and purchased 500 red worms.

FACT: did you know out of 100s of types of worms there are only 3 types that will compost food, the red worm being best?
