Homemade Bitcoin Mining Dehydrator

Currently processing elderberry with a S9 set to 980w. I designed the dimensions of the box to be similar popular 1000w consumer dehydrators since that's the wattage at which the S9 is most efficient.

The door of the dehydrator simply presses into the front and I can control the vent gap for more or less airflow which also helps to control the temperature.

Highest temperatures I've been able to measure are around 135°f, which I read is good for fruit. I can get temps as low as 90°f with higher fan speeds and larger vent opening.

I cut a hole in the back of the box so the exhaust fan of the S9 fits snug. That way I can easily remove it and use for a different heating application when I need to.

The energy efficiency of this contraption knocks the socks off any other consumer dehydrator available and it cost next to nothing to build. All I had to buy was the screen for the trays for around $10. I had everything else laying around already.

I can fit a gallon of elderberry or 2 gallons of grapes per load with the 10 trays. Each bach of elderberry takes about 24hr to complete and the raisins take at least a couple days. So far the elderberry and grapes are all I've had a chance to try. Next up is garlic to make garlic powder. #plebminer #bitcoin #bitcoinmining #permaculture #permies #grownostr #homesteading #doublespendenergy #dehydrator #heatreuse
