Can Nostr zaps keep free, open-source Bitcoin tools alive?
gotta re-up solo.cat tomorrow. It’s been running nearly 3 years as a free solo Bitcoin mining tool.
If you’ve gotten value from it (or just want it to stay online), please consider tossing a few sats my way. ⚡️
Sponsor spots are open too, can add your logo to the site’s sponsorship section.
Let’s see what the ⚡️power of #bitcoin #nostr can do. Please like, share and repost.
Thanks,
@OpenSats Getting a grant rejection on Thanksgiving is wild timing. We’ve been pouring everything into HeatHarvest, waiting until after the holidays would’ve been a better move? Really disappointing and pretty poor timing.
Hope everyone is having a nice, relaxing weekend and getting rested up for the week ahead as we prepare for Thanksgiving and the holiday season. 🦃
Out feeding the #Bitcoin Heat compost worms, and as many of you already know from the previous post, we switched the HeatHarvest greenhouse to spring conditions not long ago. So even with freezing weather outside and very little daylight, inside the greenhouse the plants get 24/7 light, natural daylight plus plant lighting from dusk till dawn. These grow lights are very bright and mimic actual sunlight.
Why are the Bitcoin compost worms so important? For starters, they provide nutrients to all the plants inside the HeatHarvest greenhouse through worm castings and worm casting tea. What are worm castings? That’s for a later video where we can dive deeper into the subject. The compost itself also off-gasses CO2, which is vital for tightly buttoned-up greenhouses that experience extreme winter conditions outside. Once we make it mostly airtight to lock in all that precious Bitcoin mining heat during the coldest days of harsh winter, the plants still need CO2. Our primary solution will be the worm compost bins we made from recycled Bitmain S21 Pro miner chassis.
Currently, the Bitcoin compost worms get organic carrots, wheat bran, and sweet potatoes. Later on, as the greenhouse flourishes, we’ll start giving the worms scraps from the greenhouse itself, like leaves from the sweet potatoes, cuttings, or whatever needs to be composted. That’s how the HeatHarvest greenhouse becomes a self-sustaining unit that recycles within itself. Inside this closed organic ecosystem, everything is mutually beneficial, all working together in a perfect 24/7, 365-day-a-year, organic food-producing habitat made possible by Bitcoin mining heat. Even if there’s a blizzard outside, inside it’s always giving spring and summertime vibes.
We’ll also deploy a smart CO2 device to feed the plants on demand if the compost bins fall short, especially deeper into the winter when we have to mostly seal off all ventilation to the greenhouse. It’s going to get very interesting come January and February 2026, so stay tuned, much more on the way.
Also, as you can see, the purple sweet potatoes, Japanese honeysuckle, and avocados are really embracing the new spring conditions, just look at the exciting growth in such a short time, can’t wait to see what the next couple of months bring.
Huge congrats to another small-hashrate solo #Bitcoin miner who just landed a solo block with what looks like a #Bitaxe Gamma on
@Dr -ck ‘s ckpool, another block for the plebs.
Every Bitcoin block is ultimately found by a single ASIC chip.
Stop telling yourself it can’t be yours, this is living proof that you can do it.
If you drift away when the price dips, stop building, stop mining, stop running your node, stop capturing heat, stop saying GM/GN, stop posting, stacking, podcasting, or streaming, that’s okay. It just means you were here for the moment, not the mission.
The real ones are still here.
1 Bitcoin = 1 Bitcoin.
Vertical hydroponic Bitcoin mining heat grow pods update!
Designed and 3D-printed custom grow pods that snap perfectly onto the vertical hydroponic system. The curve of each pod matches the main tubing, so they sit snug and semi-lock into place without extra hardware.
Next step: custom seed sponge fittings and grow spinach in the pods. Once we’ve run a few tests and made any necessary revisions, the design source files and build notes will be up on the HeatHarvest GitHub repo, 100% free and open source.
HeatHarvest is happening in real time, the final pod finished printing about an hour ago, and this update followed right after. I’ll be pushing out updates as often as possible so anyone who wants to sprout their own #Bitcoin HeatHarvest greenhouse has the resources to accelerate their build.
Fancy waterproof sponsor stickers arrived. Conditions in the HeatHarvest greenhouse definitely call for a sticker that doesn’t fade, discolor, or fall off. #bitcoin #HeatHarvest
Prototypes are on deck. We’re going mostly radio silent to lock in on a project three years in the making. The only thing we’ll be actively updating on socials in the near term is HeatHarvest season.
Comms will be limited.

Major Update: Bitcoin Mining Heat-Capture Season 2025
HeatHarvest Greenhouse / Proof-of-Growth: Purple Sweet Potatoes & Crawfish, Vlog 2: Claws & Roots , Move-In, Tune-Up, and Flip to Spring. This Vlog features several big upgrades:
Insulated, layered floor: Rubberized PVC, coconut coir, and cement "layered", insulated concrete slab so our precious Bitcoin heat isn’t wicked into the earth. Detailed post on the layered insulated concrete will be added to this thread soon.
Crawfish move-in: Two breeding tanks plus the orange stock tub now hold backup breeders and bulk crawfish stock. We also built and assembled a custom vertical hydroponics growing system that ties directly into the stock tub.
Biological synergy: Crawfish produce ammonia that microbes convert to nitrite and then nitrate for the plants. As plants take up these nutrients, they scrub the water, creating a cleaner, healthier environment for the crawfish and steady feed for the plants.
Temporary automated heating: A modified S19j Pro running a two-hashboard, 120 V modded configuration is keeping the HeatHarvest greenhouse warm, even after a recent drop to 20 F. A simple thermostat brings the #Bitcoin miner online with target of 80 F; so far, temperatures have held between 60–77 F. With winter setting in, the rig hasn’t turned off, so we’re steadily mining Bitcoin and producing HEAT.
Purple sweet potatoes moved in: Twelve 10-gallon grow bags filled with organic soil and our cloned purple sweet potatoes grown from seed potatoes over the spring/summer are now in place, for roughly 960 pounds of total grow soil medium in the greenhouse.
Flip to “spring”: We switched the greenhouse to 24-hour light, sun by day, and an auto-switch runs the grow lights from dusk till dawn. This extended photoperiod, drives aggressive vegetative growth and pushes the HeatHarvest greenhouse into “spring.”
Status:
So far, so good. It took two days to dial in all systems. The real challenge was balancing the closed, circular system between the crawfish stock tank and the vertical hydroponics system. We officially switched to spring conditions three days ago, and we’re already seeing spinach seedlings showing strong growth.
What’s next for Vlog 3
Command Console: Time to give the console some attention and make the HeatHarvest greenhouse as smart and automated as possible. This will house the automation “brain” and our more permanent heating system. We’re waiting on a unique piece of Bitcoin-mining hardware for the final heating setup, it’s going to be very special. Stay tuned.
More spinach starts: Germinate and raise seedlings to 4 inches in a 50/50 coco coir + perlite blend. This keeps roots in a loose medium for easy transfer into the vertical hydroponics system, fed by nutrient-rich water from the crawfish stock tank.
Healthy crawfish: Keep parameters dialed so breeding ramps up and egg production begins.
Build the smart M.O.E.M. (Mining Operation Environmental Monitor), HeatHarvest Monitor (open source): Custom PCB + hardware + firmware (released free and open source on the HeatHarvest GitHub). It will monitor temperature, humidity, O₂, and CO₂, and send email/notification alerts on anomalies (e.g., sudden temperature drops). It will also log long-term data for this season and future HeatHarvest runs. Also feature a web app that allows us to monitor the HeatHarvest greenhouse 24/7 remotely.
Sponsorship stickers: We also need to add our permanent sponsorship stickers. The greenhouse humidity destroyed several sticker rounds, so we’ve ordered permanent vinyl replacements for the sponsor banner.
Current plants in the HeatHarvest greenhouse:
Purple sweet potatoes, spinach, mint, avocados, and Japanese honeysuckle with more to come as space allows.
Countless micro-projects are underway before Vlog 3. Stay tuned, I’ll keep this thread updated until the next Vlog is live. Would like to welcome our latest Sponsor Ungovernable Misfits. Interested in sponsoring? There’s still time DM or email us.

Ungovernable Misfits
FREE and open-source Bitcoin mining hardware: Don’t throw away or sell your S19j, S19k, or S19 Pro units just yet, developing something tailored for our Bitcoin-mining HeatHarvest greenhouse, semi-waterproof, moisture-resistant, and packed with some intriguing extras. Securing the hashboard with lock mechanisms was a priority, along with a tough and durable 3d printable frame that ties cleanly into other materials after printing.
Working in mounts for alternative thermal-management modules, currently prototyping. Beyond the core functions, kept the pleb #Bitcoin miner in mind with this design, many pleb miners have small print area 3D printers, parts are kept within ranges to fit smaller printer beds. This is Prototype 1, the basic concept. Logged a dozen mod notes, now it’s back to CAD and reprints. Stay tuned, this is shaping up to be perfect for solo plebs mining at home and DIY Bitcoin heat capture projects
