FREE and open-source Bitcoin mining hardware update: Prototype 2, revised S19j / S19k / S19 Pro single-hashboard HeatHarvest case, custom-built for a specific role in the HeatHarvest greenhouse and designed to be semi-waterproof. Keep in mind, one of the primary goals of this design is to be modular and printable on a modest small-bed 3D printer, so the average pleb Bitcoin miner can make it at an affordable cost. Made about a dozen modification notes, and now it’s back to CAD for the next revision. Stay tuned. How it started, how it’s going. #bitcoin https://blossom.primal.net/c61bdf7334b83faa5d570bc2f59ad805475f0d483cac384ebb891acea5044569.mov

Quick design update for the floating plant holders used to biofilter the crawfish breeding tanks by removing excess nutrients, nitrogenous compounds, and suspended organic matter, improving overall water quality and system stability. In the initial design, buoyant support was sufficient under calm conditions but failed to adequately distribute the load of larger plants across the water. As a result, disturbances such as aeration and routine feeding caused tilting and instability. The revised design increases the effective surface area and redistributes mass more evenly, enhancing buoyant stability and reducing tipping under active conditions. The update also integrates the vertical hydroponic pods from the looped hydroponic vertical system, enabling seamless transfer of plants between the vertical hydroponics and crawfish breeding tanks. The pods semi-lock into the new floating holders, allowing quick swapping and rotation across different growth media and systems within the HeatHarvest greenhouse. #bitcoin https://blossom.primal.net/df6237bb92210dbf3271fb939b95de92c3bb8c4f5248c99c249144d4fb0a04e8.mov

Never stay stuck in failure or rejection. Study what happened. Own your part if there is one, find the real root of the setback, extract the lesson, and commit to not repeating it. Then iterate, re-energize, lock back onto your vision, and keep moving. Life is full of speed bumps, hurdles, and hard hits. The real goal is to move through them without losing your optimism, to protect your mindset while you keep moving forward. When you fail or rejected tell yourself “NEXT” Say it out loud if you have to, and then get back to your goals. Very often, just on the other side of rejection, something positive prevails. https://x.com/documentingbtc/status/1994402648649502879

Thanks, nostr:npub10pensatlcfwktnvjjw2dtem38n6rvw8g6fv73h84cuacxn4c28eqyfn34f 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.

Happy Thanksgiving. 🦃 We like to start our days with gratitude, really sitting with the root of what we’re thankful for. The obvious blessings always come first, health, family, the people we love, and community. This year, we’re especially grateful for Bitcoin open-source builders, and for the profit, grants, donors, and sponsors that make the work possible. There are a lot of misconceptions about “free” and open-source Bitcoin hardware, software, and 3D designs. Nothing in the universe is truly free; everything costs energy and effort. That “free” repo you clone or 3D file you print represents hours, months, sometimes years of someone’s life, late nights, missed weekends, and real financial risk. Behind many of those projects is someone else who worked hard enough to create a surplus, then chose to allocate part of that profit to fund open source. Bitcoin sponsors, donors, and grant issuers don’t conjure capital out of thin air. It’s earned through hard work, PoW, and energy, then deliberately redirected into a shared “Bitcoin open knowledge bank” that builders, educators, and the next generation of Bitcoiners are already drawing from. Open source isn’t “giving things away”, it’s a conscious investment in humanity’s future. Across history, people have understood that some portion of what we have should flow back into the greater good, tithes, offerings, charity, endowments. Different rituals, same core idea, a slice of our time, energy, and resources is set aside to grow the collective knowledge base and secure our shared future. We try to live that out, we donate our time and skills, and we pour a big share of our resources into open-source Bitcoin mining hardware, just like many in this space. Profitability, hard work, and energy sit at the core of sustainable open source Bitcoin. Hardware doesn’t buy itself. Power bills don’t pay themselves. Without profitable individuals and companies choosing to reinvest their surplus back into open source, innovation would slow to a crawl. Profit and open source are not enemies, profit is often what keeps open source alive. Satoshi’s own sacrifice is still largely unknown in detail, but we know it was immense, years of work, then walking away from recognition and unimaginable personal wealth so millions of strangers and families could have a chance at a better future. So as we move through Thanksgiving and beyond, the next time you download a “free” tool or print a “free” design, pause for a moment. Honor the time, risk, and sacrifice that made it possible. You may never know what someone gave up so you could build on top of their work. If it’s within your means, give back. Fund a builder. Sponsor a project. Support a grant. Contribute your skills. That’s how we keep open-source #Bitcoin growing for the next generation.

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. https://blossom.primal.net/253137459d0efecc530def74df16510aa1bf4ba6c419e97b602cfef7880728d7.mov

Huge congrats to another small-hashrate solo #Bitcoin miner who just landed a solo block with what looks like a #Bitaxe Gamma on nostr:nprofile1qqsq8m206z2clq6nk052sjfm46qtxk5x3gv7c34xentqe4fw2tfjjcspr9mhxue69uhh2mngdaehgetywaskcmr9wshxxmmd9uq32amnwvaz7tmjv4kxz7fwdehhxarj9esh2tcgcetvj ‘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. https://blossom.primal.net/83fc86143a915579bf92153d7f7ce59711f834b7c78abd1e557fc04a8ae784fa.mov

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 https://blossom.primal.net/c44560796909392709495433322d36e625bcad5b2d9b91200ca21b7397bfe9da.mov

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. #bzm2 #fezzik #bitcoin #mining

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.

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 https://blossom.primal.net/95b8850e1ef38668970c189399bc66b08b32d618e20d736faabdb23214b5fff1.mov

W21: E-Waste Conversion, Bitmain S21 Pro Chassis → Gravity-Fed Organic Worm-Casting Miner W21 is true e-waste upcycling. We repurpose the empty Bitmain S21 Pro chassis as a durable, stackable shell for a gravity-fed vermicomposting system. The design is open-source, and every 3D-printable part is in the HeatHarvest GitHub repo The result is simple and powerful: kitchen scraps and crop trimmings go in; microbially rich worm castings come out, and those castings feed our HeatHarvest purple sweet potatoes in the heat-capture greenhouse. Why an e-waste conversion? Obsolete mining hardware is both a problem and an opportunity. The S21 chassis gives you precision metalwork and mounting points that would be costly to fabricate from scratch. Converting that shell into a worm-casting miner keeps material out of landfills and turns an old form factor into a tool for organic #Bitcoin mining heat food production. What worm castings are and why they matter? Worm castings are the end-product of vermicomposting: a stable, humus-rich material loaded with beneficial microbes, plant-available nutrients in gentle concentrations, and a high cation-exchange capacity that buffers fertility. In soil, castings improve structure aggregation, water infiltration and holding, and nutrient cycling at the root interface. They’re forgiving low-salt, low burn risk, and effective in small, regular doses. Castings provide the biological side of fertility: resilient, living nutrition that scales with your grow. The species that makes the magic happen and its life cycle: red wigglers Eisenia fetida E. fetida is a surface-dwelling compost worm adapted to rich organic matter. It thrives in loose, moist, well-aerated bedding and responds quickly to steady conditions. Cocoons typically hatch in 2–3 weeks temperature-dependent; juveniles reach maturity in 6–8 weeks; adults lay cocoons regularly when moisture, temperature, and food are good. Feed a thin, weekly top layer of chopped vegetable scraps, coffee grounds are fine. Avoid fats, oils, meat, and salty foods that sour the w21 Maintain moisture with light misting if dry, and add dry coconut coir if it’s too wet. Worms migrate upward to fresh feed, while finished castings consolidate below by gravity. Design logic: gravity in, gravity out The W21 uses a vertical drop-through stack inside the S21 shell. New feed is always added at the top; as worms move up, the lower material matures and drops into a sealed harvest drawer for easy collection. Gravity is AWESOME 😎 Using castings in the heat-capture greenhouse Purple sweet potatoes respond beautifully to castings, tuber quality depends on even moisture, steady micronutrients, and a cooperative microbiome. Castings help deliver all three. Circular systems and why composting matters The goal is sovereignty through cycles you control. Scraps feed worms; worms make castings; castings feed the next crop; the crop becomes the next scraps. ♻️ Castings reduce dependence on synthetic fertilizers, build soil structure that buffers stress, and equip roots with microbial allies that supply nutrients when plants signal for them. Because the W21 is built from an otherwise obsolete chassis, the loop begins before the biology: first you recycle a device, then you recycle nutrients. That’s sustainability in practice, local inputs, local processing, local food + Bitcoin heat = 😎 W21 proves that an obsolete miner chassis can become a living machine for Bitcoin heat capture, food production and a champion of sustainability. The design is open, the parts are printable, and the process is teachable. Build one. keep it steady, feed it thoughtfully, and put the castings to work where they matter most in your Bitcoin mining heat-capture greenhouse.

First purple sweet potato flower of the season, a beautiful milestone and a timely warning. Flowering coincides with shorter days and cooler nights, which push the vines toward senescence: leaves will start yellowing, drop off, and growth will slow dramatically. For our 2025 Bitcoin Mining Heat Capture greenhouse, that means it’s a critical time for the concrete floor upgrade. We’re going to pour a concrete slab with a rubberized barrier and insulation to prevent conductive heat loss into bare soil. Without it, the ground acts like a massive heat sink and wicks away precious BTUs from the Bitcoin heat capture greenhouse. This weekend is all about slab prep and installing a proper drain. Mixing and pouring the concrete will most likely take place on Monday. This flower bloom is on one of our mother plants. Mother plants are your year-round insurance policy, keep them healthy and protected, and you can always take cuttings to restart a crop. What’s timely now is pouring the concrete slab, moving all the plants into the greenhouse, and restoring springlike conditions. We’ll simulate spring with Bitcoin mining heat and supplemental lighting to maximize productivity. With this setup, even in 0 °C in the worst of winter conditions we can grow food as if it were peak spring or summer, faster than ever.

Fun fact: Our Purple sweet potato flowers are diurnal: they open in the morning and begin closing by afternoon. By later today, this bloom will be mostly closed and easy to miss. https://blossom.primal.net/c6e3e68801a55ea882c1891fc92af50b6027cfb89eeab2a74a3858c2d6ac98eb.mov

Meet one of our bull breeder crawfish. 🦞 Crawfish are a perfect fit for Bitcoin-powered heat capture and food production: warm, stable water shortens cycles, and focused selection delivers noticeable size gains in as little as 2 generations (often 8–12 months in warm systems). After harvest, we can mill the shells/claws/exoskeleton, rich in chitin + calcium, to gently buffer acidic soils, feed beneficial microbes, and return minerals to the grow soil in our Bitcoin heat capture greenhouse. Protein to the plate, nutrients back to the soil, a true sustainable, organic, circular loop. Nutrition (per 100 g cooked): ~77 kcal, 15–17 g protein, 1–2 g fat, 0 g carbs; high in B12, niacin, selenium, zinc, phosphorus, copper, with moderate omega-3s, lean, complete protein. Why crawfish excel in aquaponics & sustainability? Biological organic synergy: Crawfish produce ammonia that microbes transform into nitrite and then nitrate for plants. As the plants take up these nutrients, they scrub the water, creating a cleaner, healthier environment for the crawfish. -Heat-reuse friendly: Mining heat accelerates growth and shortens generation time. Also, it makes crawfish a viable food source in colder climates through Bitcoin heat. -Circular organic sustainable diet: We can feed organic vegetables that we grow to the crawfish and cycle nutrients within the system. -Zero waste: Shell powder (chitin + Ca) is a gentle, microbe-boosting plant soil . -Building looped sustainable food systems that recycle #Bitcoin heat and nutrients. 😎♻️ https://blossom.primal.net/033df265ab8358e10af2a98282148073355058643e00574828e42ca2ba0dadc8.mov

#Bitcoin Mining Heat-Capture Season 2025: HeatHarvest / Proof-of-Growth, Purple Sweet Potatoes & Crawfish. vlog 1: Dry Run . We’re excited to launch the first of many Bitcoin Mining Heat-Capture Seasons. Each year, we’ll showcase a fresh set of projects that turns Bitcoin mining heat into real-world impact. For 2025, our focus is global food sustainability. Even now, many communities and regions lack reliable food security and access to modern financial tools. Bitcoin mining can help address both. By capturing miner heat, people can grow food locally while earning bitcoin and connecting to global commerce. Imagine a remote village with a short growing season but access to electricity or generators. With Bitcoin-heated cultivation, that community can extend the growing season indefinitely, feed itself, and use Bitcoin mining rewards to upgrade infrastructure, more reliable power, better facilities, and a higher quality of life. Also Bitcoiners are always wanting to be more self-sustaining, to know where their food comes from, and to avoid synthetic inputs common in industrial agriculture and commercial food supply chains. In Bitcoin we say, “Don’t trust, verify.” Apply it to food: grow it yourself and verify every input. “Proof-of-Work” your own food, no trust required, just quality, organic, self-sustaining harvests powered by Bitcoin heat. Throughout this season, we’ll share practical, open resources, designs, build guides, and results so anyone can adapt Bitcoin mining heat to their own goals. Follow along, grow with us, and let’s turn hashrate into harvest. Huge thanks to our sponsors for providing the tools, resources, and equipment that accelerated this season. Interested in sponsoring? There’s still time DM or email us. Together, we can address real-world problems with Bitcoin mining heat.
