- A very cold shed - zero degrees showing on the temperature display. Failed buck converter probably didn't like the solar panel open circuit voltage and has failed short. I've been testing Antminers on a range of voltages between 13.6V and about 11V.

The ice in the bucket also confirms below 0 degrees :) just like your thermometer it also can't tell us how much below.
Ha ha, yes that's true :)
I thought the shed might be the end of your moist electronics days, but moisture finds a way! I wonder how effective it would be to water-cool the ant miners and dump the heat via heat exchanger into a standard central heating radiator. Shed's already wet so you might as well have some plumbing in there too! :D
Ah so everyone has a plastering bucket of mud with a bit of grass and some water in it.
I did notice the cable tie, so thanks for the answered before asked.
The blow up, do you not have diodes installed as a lot don't seem to have them and this blows them up sometimes..
I wouldn't know anything about that... With my solar panel tester I made...
😅
You need to get on the hot roof/cold roof fix..
Shed’s weathering nicely.
A common retrofit solution to condensation dripping off the inside of a corrugated roof is to spray coat the inside of the corrugated sheets with polyurethene foam - seems like 5-10mm thickness is plenty. The idea isn't to keep the interior space warm - just stop the condensation forming on the inside of the roof.
Have you considered lining the roof with fiberglass insulation? That should make it easier to keep warm in the winter and keep moisture from reaching the interior of the roof.
Thats a better idea than mine of plasterboard that would get damp. A greater pitch 1'st thought may also help the drops run, although the council probally have rules for roof hight.
I once touched fiberglass insulation, I can still feel it itching.
I mean foam board would also be an option, which would be better if the beams aren't at standard widths apart. As for touching fiberglass insulation, I avoid touching the stuff. I don't like smelling it either.
Hi, Julian!! You will find a way to stop the moisture problem.
We can't have it so damp around all those precious electronics!
💦🤨⛲😟💧😥🌊😩😭🐳😠🏝🙄🛳🙂
Lovely shed update.
Too bad about the condensation dripping. But roofs that get cold, need an underside that can absorb, and later evaporate, moisture.
Perhaps a (yearly replaced) cardboard thingy would be able to absorb, and later evaporate. Or perhaps particle board, that gets replace every few years, might add this absorb/evaporate ability.
Where I live, for the underside of steel roofs, they often spray with a course cement/ceramic layer, in order to add that absorb/release ability, so the inside of the attic no longer needs to deal with water dripping.
They use the cement/ceramic stuff as nothing bad will grow in it, while it is "wet" during the (daily) absorb phase.
Hate to say it 33yrs experience, this problem would have never happened if a membrane was installed before the roof. (also walls) Ventilation is key ,use your batteries to run a dehumidifier .
I love the shed... But wouldn't it be better to spend few bucks on isolation? At least roof?
Recently I isolated my shed and I used just cheapest 0.5 and 1cm thick foam(that normally is used on floors. But who care it was cheap 😊) and plywood. It was not that expensive and maybe it's not super efficient in terms of keeping temps but it do something as I can't sit there for more than few minutes an most important, I no longer have issues with drips and moist air. 😅
I reckon the only way a shed could maintain a reasonable working temperature, in winter, would be to build a shed within a shed within a greenhouse.
Insulation panels on the walls and roof would make a big difference to the amount of energy needed to warm it up. My workshop has insulation and warms up very quickly as a result.
The wires to the Power Queen seems to me a bit tin-isch :) But that is maybe because the other wires are quiet generously spec'ed:)
Why isn’t your shed properly insulated and heated?
Also roofs such as that (more so metal ones) radiate to space and moisture in the air preferentially condenses on the underside rather than anywhere else.
25mm of PIR, topped with 11mm OSB, a layer of tyvek wrap, followed by the existing roofing will fix it.
Your temporary door stop is pretty permanent.
Glad to see you moving forward with Sodium Ion. How accurate have the suppliers been with their Sodium products? Any unforeseen issues?
Many comments here on how damp garden sheds can get (as I know) - dripping ceiling from condensation etc. Wind born spray from rain + gales - shed weatherboards should at least have tar paper lining as per old school. Then there's squirrels, rodents, insects, ants, spiders etc - Watts not to like. But very wise not to bring that lot inside your house. BTW have you got an outside emergency breaker system (IMHO you might consider Anderson connectors as they are designed to be pulled apart - better than nothing). Do I see some proper cable cutters, gloves, goggles, hanging up ? Sand bucket to hand, Water bottle to extinguish arc flash. Safety First please, lots of kiddies following you here
just glue isolation material on the roof if you don't want to screw it i think some isolation will help whit the condensation
what happened to the diesel heater? Could that keep moisture at bay?
can you not fit a diesel heater in the shed and run it low to keep condensation and dampness away , bonus being it will keep you warm as well lol
Two or 3 strategically located 12 volt computer fans, running 24/7, might help with your condensation problem? I'm sure you have sufficient battery capacity to run them.
Some sort of electrical heating?
What's an Ant miner?
An Ant that hasn't reached adulthood.😏 Simply put, Antminers are Bitcoin mining equipment. They are regarded as the world's most potent mining equipment. For various cryptocurrencies like Bitcoin, Litecoin, ZEC, and Ether, there are Antminers.
Could you not just screw some 25mm insulation board (celotex, Kingspan etc) to the underside of the roof to keep out the condensation and keep a bit of the warmth in?
Couldn't you just put a plastic cover hanging under the beams which then directs water dripplets to the lower end of the building?
I never understand my you want to work in a shed. i sit in a nice warm room with all my toys.
did get a bit colder today as i had the window open as the laser was cutting acrylic and I had to throw the vent pipe out.
I bet his other half has told him to work out there 😉
Lucky you. I have a workshop in the house that is 2m by 3m - that's smaller than my car. The shed is the other half of my allocated workspace. It's all very impractical.
@@fredflintstone1 That's why I've never built a shed 🙂
@@JulianIlett well just measured my toy room, and it's 3m x 2m!
How I get 2 PC's 3 monitors, 2 3D printers, a K40, 2 HAM radio's + PSU's (HF, VHF, UHF) (HF VHF), and store a lot of junk i don't know. Looks like i might have to build a back room on the chicken house when i build it in the spring. 🙂
@@TheEmbeddedHobbyist Haha, or dig down, add another level :-)
its not "extremely cold" unless the whole bucket is ice, otherwise its just cold
I'm surprised you lasted that long out there as long as you did. That's a criminally low temperature!
Another diesel heater in the shed maybe running off one of your many batteries.
A nice in the modular shed update, you want to work in there when it is cold?? has the wife kicked you out??? 🙂
When I say 'working', I mean mostly moving things around. It's like one of those sliding tile puzzles. Working in a tiny space is hopelessly inefficient.
