Bitcoin Mining Clothes Dryer Here at the homestead we host guests at our house as well as a 20ft yurt so one of the largest power usages is the electric clothes dryer. In the busy season, the dryer is usually running for several hours a day. It made a lot of sense to use a Bitcoin miner for the heat instead of the heating element in the dryer. image https://imgur.com/eGKbv0G image I tried to use what I already had as much as possible to connect the miner to the dryer, so for less than $100 I was able to make it work. Basically needed a 20a 220v breaker and 220v outlet plus some ductwork. I simply cut a hole in the heating duct in the back of the dryer and attached a 6in duct coupling to it. If I need to I can cap off the coupling and continue to use the dryer as normal. Basically if the Bitcoin miner breaks down I won't be stranded without a dryer. To operate, I set the dryer to timed dry, set the heat to air dry, and turn on the miner. After using it for a dozen loads or so it definitely works well. Next I will be working on how to reduce the noise from the miner fans but to start I wanted to make sure it was capable of drying laundry first. Feels good to get sats back for one one of the largest power usages on the homestead! #permaculture #permies #homesteading #grownostr #meshtadel #selfsovereignty #plebminer #homemining #bitcoinmining #bitcoin #doublespendenergy #hash2heat #mine4heat #stacksats #stackingfunctions View quoted note →

So I had a half fleshed out thought for reducing noise... Correct me if I'm wrong but the noise is coming from the fans no? The sole purpose of the fans are to pull the heated air off the miner. I think you can remove them in this application. The dryer already has a system to pull the hot air into the drum, all you need to do is tap into it. Since you're already pulled the back off the dryer, you could just build a box and attach it directly over the hole. Take the case and the fans off the miner and stick it in the box. The existing system the dryer uses to pull hot air into the drum will simply pull it from the bare miner. You'd have a silent miner but it can only run while the dryer is running...
very cool idea, if you gonna make heat , make it with ASICs.. Maybe I should open a Bitcoin laundromat and let other people pay to run the ASICs.
I was amazed at how much air was leaking out with the positive pressure from the miner fans. I was able to seal it up much better than it was.
It's pretty simple, cut a hole in the back of the dryer heat vent close to where it vents into the drum, then put a coupling and attach duct. Block the heat vent in some way so all the air goes into the drum. Probably disconnect the heating element... View quoted note →
Probably this is why they say bitcoin is use for money laundering… 🤪
The cycles are about the same length and it's probably the same as the medium heat setting on the dryer I have. I haven't figured out a way to measure how much power the dryer was using on each cycle. It seemed like the heating element would turn on and off while the dryer was running. I don't have a meter that can record the total power usage for the cycle, so maybe I could stand at my clamp meter for 40min taking notes while its running to get a rough idea. My best guess is that the miner is pretty much on par with the power usage of the dryer. There hasn't been a huge spike in the overall monthly power usage since I started using it and it was running a few hours a day in the summer time at least. If the miner was using more or less power than the dryer I didn't notice it in the power bill.
Thought this might be a good resource for you @rev.hodl This guy did a similar modification to his dryer except pulling from attic air not from the exhaust of a miner. He uses a “TED” to observe the power differential from the two ways. Just thought I would pass it along in case it was helpful.
That's great, thanks for the response. I didn't really factor in the cycling that would happen on the element, you may even have more consistent overall heat on the miner once it's spooled up. Cheers
One year ago I recorded a podcast with @Ungovernable Misfits talking permaculture and bitcoin in general. This clip is a good summary of my high level thoughts on Permaculture and Bitcoin and was basically the ideal I was working towards throughout the year. View quoted note → The podcast as a whole provides a good reference point for a lot of what has happened on the homestead over the last year. I'm not sure why I thought to detail so many of my plans for the year, maybe hold myself accountable. All in all, I was able to accomplish almost everything I mentioned throughout the podcast in the last year. Take a listen and check out this year in review mega note. February was defined by maple syrup production, the threads aren't as cohesive as I was still learning Nostr and developing my style. View quoted note → March the highlight was working on the 20ft tiny house, still haven't quite figured out Nostr. View quoted note → April was marked the completion of the Bitcoin mining dehydrator, one of highlights of the whole year for the homestead. View quoted note → May was the sweet spot of sunlight and waning colder temperatures which lead to lots of pleb mining at the homestead. The solar power was flowing and the dehydrator was constantly loaded. The cold frame was growing cannabis and the portable S9 space heater was saving lambs from hypothermia. View quoted note → June the sheep were grazing the pasture at it's finest and the yurt was booked solid with guests View quoted note → July the bitcoin mining clothes dryer was completed in the peak of the summer tourist season. A project I have been thinking about and working towards for over 6 months. View quoted note → August I made my second appearance on the Bitcoin Rapidfire podcast talking about mining on the homestead. View quoted note → September the food forest ripening and cannabis colas were forming. View quoted note → View quoted note → October the sheep were finishing out the season strong making for some of our best lamb we've grown. View quoted note → November we rounded out a great year with the horses after finally realizing our goal of using them for carriage tours. View quoted note → December I spent spreading the word of the intersection of Bitcoin and Permaculture on the @npub1cl42...gf39, @QW, and @npub1svc4...a9g9 View quoted note → What a wild year, it's been all that more amazing to share it with everyone on Nostr. Permaculture, Bitcoin, and Nostr is facilitating a new permanent culture in which we are all building together! #permaculture #permies #homesteading #bitcoin #meshtadel #bitcoinmining #plebminer #foodforest #weedstr #cannabis #rotationalgrazing #yurt #grownostr
Breaking in a new miner at the homestead image Making more hashes than ever with solar power thanks to this new S19kpro (Urlacher by Altair Tech). When I first tried firing it up on the solar power system, the breaker was tripping immediately. After some trouble shooting, I solved the problem by swapping out the power supply. image I won this miner at auction during the lake satoshi retreat. My goal was to sell enough homestead products to pay for the miner but I only got halfway there after selling everything I had with me. All sats paid for the miner were donated to the Hope House in El Salvador. The miner was generously donated by both Altair Tech and Chet (the most die hard supporter of lake satoshi you can find). Not only did I get a new miner for the homestead but I was also able to negotiate a better power rate recently too. Thanks to some fuzzy pleb miner math, I am happy to hash during the day when the sun is shining then move the miners over to grid power and hash from 9pm to 7am when the power costs are lowest. image I also made some upgrades to my clothes dryer as well. Adding a more efficient Asic, quieter fans, and a sound deadening enclosure. Now the dryer itself is louder than the miner during operation. Additionally thanks to the new power rate, I can let the miner run in off peak hours continuously wether drying laundry or not! Staying ahead of the halving, difficulty adjustment, and fading sideways price action has made it difficult to keep the sats flowing at the homestead with mining. So far we are just barely able to stay ahead of the curve and continue to support the network, do some productive work with the heat and get some sats out of the deal too. The sats might cost more than the current spot price of Bitcoin but for now I value the participation in Bitcoin more than the purchasing power. #permaculture #permies #homesteading #meshtadel #bitcoin #mining #bitcoinmining #homemining #plebminer #offgridmining

Alternatively if you have a large space for hang dryng these clothes you could hang them and then use the air from the miners to flow through the space and have less wear on the clothes.
I've seen versions of that. Definitely an option! Added bonus, the miner isn't fastened down so you could use it for other jobs while it's not drying too.
Have you noticed that it takes any longer to dry the clothes? Have you compared the electricity usage and sats output by chance? I’m really curious about any hard details you can gather on this because it’s something @Jeff Swann has been talking about for a long time and I’d considered it as well. Heating the house with miners has been great, but it’s significantly more expensive than the gas heat we had (our gas is significantly cheaper than electrical), but we don’t get that benefit with the dryer. So that might make it a more interesting proposition. 🤔
I tried to do a direct comparison for the power usage but it was too difficult. The dryer seemed to draw a lot of amps to get the heating element hot then power down and cycle on and off again throughout. I didn't have a meter that could easily track the power usage for the dryer. As far as time to dry, I treat drying a little differently in my situation. I try to keep the dryer running continuously throughout the day as I do laundry. So as soon as the washer is done, hopefully the dryer is done too. That way I can keep feeding the dryer. All in all, I've been very impressed with how well it works for how cheap/simple it was to modify the dryer. If you have a miner sitting around, not hashing, why not find a way to put it to work?
