Hey everyone! I wanted to share an update on turning Bitcoin miners into space heaters for my home. It's been a wild ride filled with 3D printing mishaps, hardware tweaks, and plenty of "learning opportunities" (a.k.a. mistakes).
To house these mining heaters, I needed special enclosures. So, I dusted off my 3D printer and got to work. The high-temp filament arrived, and I started printing the heater case for the Antminer S9. Things were looking promising, and I was still waiting for the actual miners to ship. The main body of the S9 heater was finished, but there was some post-processing to heat-treat it. I decided to print some parts in resin—pieces that wouldn't need to withstand high temperatures. Innovation or improvisation? You decide.
All the 3D parts were printed, but the S9 was still somewhere out there, making its way to me. It felt like ordering a pizza and tracking the delivery driver circling your neighborhood but never quite reaching your street. When the miners finally arrived, I realized the enclosure for the S9 didn't fit the power supply unit (PSU) that was shipped. Not ideal. Lesson learned: always double-check the dimensions before hitting "print"—especially when you're using expensive, heat-resistant filament. Goodbye, $35.
Not easily defeated, I’ve decided to redesign the top of the enclosure or maybe create a new handle to accommodate the larger PSU. I’ll keep you posted on that. I replaced the stock fans with 140mm Noctua industrial fans, which are both quieter and more efficient. Now my miner doesn't sound like a jet engine preparing for takeoff, and I won't have to wear earmuffs in my own home. It's still loud, but not unpleasant.
I'm using Braiins OS to fine-tune the wattage and target temperature, allowing me to balance heat output, hashrate, and energy consumption. I'm still getting used to the operating system and monitoring energy usage, but so far, using the S9 as a heater has been interesting. My home is warm, and the idea that I'm potentially earning Bitcoin while sitting on my couch is kind of mind-blowing.
Diving in headfirst was the best way to learn. Sure, there were hiccups—like the enclosure—but that's all part of the adventure. The initial energy costs? I consider them my tuition fees in the school of Bitcoin mining. Sometimes, you just have to roll up your sleeves and get your hands dirty—preferably not with thermal paste, though. If you're thinking about trying something like this, I'd say go for it! Just be prepared for some trial and error. And maybe triple-check your measurements before 3D printing anything. Also, don't underestimate the value of a good community. I found resources like Reddit, YouTube tutorials, and even ChatGPT super helpful. Friends who can translate tech jargon into plain English are worth their weight in gold—or Bitcoin.
I'll continue to share updates as I fine-tune the setup and learn more. It's amazing what you can accomplish with a bit of curiosity and a willingness to tinker. Stay tuned for more updates, mishaps, and maybe even a few successes!
