AI turned a huge percentage of the global population into this guy, now we’re seeing what that looks like at scale.

Introducing ZapWatch ⚡️, Open-source #Bitcoin Lightning node monitor for Nostr/Umbrel/LND with OLED status, web UI, and zap celebrations. Hardware and Firmware.

“But instinct is something which transcends knowledge. We have, undoubtedly, certain finer fibers that enable us to perceive truths when logical deduction, or any other willful effort of the brain, is futile.” ― Nikola Tesla,

Join us tonight for a live, recorded beta test of ZapWatch, a new Bitcoin Lightning ⚡️ Nostr tool. Live zap window: 8:00–9:00 PM US Central (CST) = 02:00–03:00 UTC 1-29-2026 Please help us test by sending a small zap on Nostr to THIS note during the live window. Include a message with your zap, we’ll feature it in the live recording for the official device announcement. ZapWatch is a community-driven Bitcoin/Nostr ⚡️device, so we’d love your help. Can’t make it live? No problem, we’ll also include all zaps sent from Jan 29 - Feb 1, 2026 in the announcement demo as a fun playback clip. Join us and zap in!

Was asked today “So you’re really going to spend your downtime scrolling Nostr and zapping people you think are awesome?” Yep, pretty much. On most platforms, a “like” is frictionless and meaningless. It doesn’t cost anything, and it doesn’t really prove you value what you’re seeing. On Nostr, appreciation can be measurable: if someone’s post, idea, or perspective genuinely adds value to your day, you can attach a small amount of real value to it. ⚡️

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.

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

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

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.

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.

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. #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.
