Not a dealbreaker for me, just gives me pause. npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger ASICS accept a voltage range, starting around 12v to slightly above 14v. My understanding is that charge controllers in the tuner regulate voltage to the acceptable range, and the tuner dynamically tunes the chips for desired performance based on incoming voltage. I successfully ran an s9 on a 24v system. Depending on your system specs, it’s possible you could run your asic on your current system on sunny days when you have excess electricity. npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger Thanks! npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger Always down for that as well. npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger My journey to mining bitcoin from electricity created by the sun began last year on a mountain in Tennessee. At the time, my family was living off grid, exploring what it was like to take a step out of the regularly scheduled societal program and into a life of greater connection to the natural world and the people around us. We were living well with the sun as our source of electricity. So well, in fact, that there were many days that our batteries were topped off well before noon, which meant that our solar panels were capable of harvesting much more energy than we needed. I’d been hearing that bitcoin miners are really good at soaking up and monetizing excess energy, so I took a look at our system’s capacity and the miner options available. I discovered that Bitmain’s S9 miner was plug and play ready for my application, and it only cost $125. It was perfect as a low risk way to learn more about home mining and an easy way to test what it was like to mine on solar. I started plugging in the miner on sunny days after the batteries had reached full charge and it worked! I was turning the extra solar capacity into hard money. I was hooked and began dreaming of ways to optimize the system. Before long, I discovered an online community of home miners who were tinkering with all sorts of interesting ways to use miners to add value to their lives. In particular, I was intrigued by the work of @npub17h5…88mq , who builds a tuner that allows a modified S19 series miner to run on 12v dc current straight from solar panels. This increases efficiency by eliminating the AC-DC power supply miners require when running from AC power sources. I purchased a tuner box from Dirty in November and began assembling the necessary components to build a completely off-grid solar mine. This week marked the maiden voyage of the system. As with any project that pushes the boundaries of what has previously been done, the road has been bumpy and winding. What follows is my attempt to get into writing the process, challenges, and successes of this project, both as a reference for future me and as inspiration and information to anyone who is curious about mining bitcoin with solar. Before embarking on this project, I identified the following goals: 1. To invest capital in energy independence and resilience. 2. To expand my experiential capital in both solar systems and bitcoin mining. 3. To setup a relatively passive income stream that reduces the ROI of the solar system. 4. To harvest the heat from the miner to supplement home space heating. I don’t currently live in a home that I’m able to add a solar system to, so I had to get creative. Fortunately, I found a family member who was willing to host the system in exchange for the supplemental heat from the miner. I have designed it so we can move it when we move to property where we have more space. The system is an asset that should bear fruit for decades. The system is composed of the following components: 1. Solar panels. Due to the design, 12v panels are necessary for maximum utilization of electricity produced. Technically, higher voltage panels will work, but they will be limited to a fraction of their maximum output because the miner requires 12v supply. 12v panels are more difficult to find. I got mine on eBay. I started with 3 Kw of capacity, which is around the maximum draw of my miner. This doesn’t mean the panels will produce 3 kW. We’ll get to that in a bit. 2. Miner. Currently the firmware for the tuner supports Bitmain’s S19 series miners. I went with a j Pro 100Th machine. 3. Solar tuner box. This is where the magic happens, adjusting the power sent to the miner based on what’s available from the panels and batteries. 4. Batteries. 400ah of 12v lithium. 5. Racking. I spent a lot of time putting together racking that was as cost effective as possible while meeting aesthetic and functional needs. 6. Wiring, fuses, breakers, connectors. Due to the length of my runs, this required upsizing my wire. Challenges in setting up the system: 1. Panel placement. The roof I have access to faces east/west. This is not ideal. After careful consideration, I decided to place panels on each slope of the roof. My hope was to capture more hours of sun rather than focussing on peak power production. The jury is still out on whether this was a good idea. 2. Wire run. Low voltage systems do best with short wire runs because of the expense of running wire gauges that are large enough to safely carry the amps the panels produce. The constraints of my system required wire runs of up to 45ft., which meant I had to upsize my wire gauge. This was expensive. 3. Setting up the tuner box. This was mostly due to my limited technical knowledge. I was learning how to setup and operate a solar system, a bitcoin miner, and the tuner all at the same time. There’s a learning curve. I spent a couple of days foiled by a bad sd card. Slow and steady wins the race. After running the system for a few days, some things are becoming apparent: 1. The solar panels seem to be the limiting factor right now. In full sun they harvest around 750w, which is 25% of their rated maximum. My current hypothesis is that panel placement is largely to blame. The panels are flat on the roof, facing east and west. I knew this wasn’t ideal, but it seems to be even less so than I hoped. The next step is to try tilting the panels south as much as I can. Production should improve as we enter the summer months and the earth’s axis shifts to bring the sun higher in the sky, striking the panels more directly. I will need to make improvements if I expect to hash over the winter. There is enough space on current racking to add another panel or two, so that is another option for adding watts. 2. Current battery capacity will only extend runtime marginally. It works well if the sun is momentarily obstructed by clouds, but if I want extended runtimes when the sun is down I’ll need to add batteries. 3. Turning extra electricity into heat and BTC is fun! I see lots of potential to keep tweaking the system for maximum efficiency. Questions?

It was fine. npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger I started with an S9 running Braiins OS, which allowed me to tune the miner to use only the excess electricity my panels produced. I ran the miner on sunny days after our batteries were fully charged. I’m in the process of building a direct-dc solar system that will run an s19 directly from the panels without the need for a power supply. I'll be running the heat from the miner into the home ductwork. Running direct dc is supposed to increase efficiency. I’ll see how efficient it is when I get it running, hopefully in the next couple of weeks. My experience with solar mining has been really positive so far. @npub1f5p…wt3z has a thread on here about his solar mining experiences that might be a helpful resource. The Home Mining Wizards Telegram group has a lot of folks who know lots about mining in general. npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger Mining takes a lot of power, so mining 24hrs/day on solar takes lots of batteries. I've had success mining on solar on sunny days after the batteries are fully charged. If you can use the heat from the miner it's even better. Solar mining can be a way to significantly reduce the roi on a solar system. npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger Verifying my Nostr Nests identity: 8dMNGB4142hNxgvV-ObCeXWGLQQyyH5kcGY17bvuo8w https://nostrnests.com npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger Tearing out old tile.

" Can confirm. #note1fre…62ak npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger Dialing in that morning brew. One thing I love about coffee is the complexity of flavors available to those who are willing to tinker. One way I like to play with flavor is by adjusting the strength and extraction yield of my brews. Strength is simply how much coffee is in the cup, measured as a percentage of total dissolved solids (TDS). Standard drip coffee usually falls in the 1-2% range. Espesso is much stronger, say 7-12%. Strength tends to vary in various cultures around the world. Extraction yield, also expressed as a percentage, is how much of the coffee grounds have been extracted into the cup. If I brew a cup of coffee using 20g of beans and end up with 20% extraction yield, I have dissolved 4g of those beans into the brew. The preferred extraction yield varies a bit by roast style and consumer preference, but in general people all over the world tend to prefer extraction yields in the 18-22% range. I personally prefer my morning pourover with a strength of around 1.3-1.35% TDS and an extraction yield between 20-20.5%. I've arrived at these numbers after years of tasting and tracking the measurements of my tastiest brews. The device I use to measure my coffee is called a refractometer. Refractometers can be used to measure how light passes through aqeous solutions and are also used to measure the concentration of sugar in fruit, among other things. The one I use is made specifically for coffee. You don't need a refractometer to play with strength and extraction, however. Adjust strength by changing the amount of beans you brew while keeping your water weight constant. Change extraction yield by adjusting grind size (you do have a quality burr grinder, yes?). Finer grinds lead (in general) to higher extractions (more flavors). Courser grinds generally lead to lower extractions. Extract too little and your brew might taste acidic and weak with no sweetness and a finish that dies quickly. Extract too much and your brew might be astringent and bitter with a thin body. I shoot for a balanced cup with nice acidity and sweetness that lingers pleasantly on my palate. Use your pleasure as your guide. Questions? Send’em to me. #coffeechain #learnstr https://m.primal.net/HbFp.jpg npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger Are these the posts you're looking for? https://m.primal.net/HajZ.png https://m.primal.net/Hajb.png npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger 1. The weather has cleared and warmed up, so I'm back at working on the direct-dc solar mine. I got the racking installed and ready to receive panels next week. I went with Ironridge Flashvue mounts and channel strut from Menard's for the rails. This was the most cost effective solution I found that still met my aesthetic and safety desires. I'm starting with 3kw of solar, with enough racking to be able to add another panel or two if I decide I want more capacity down the road. The panels will directly power an S19j pro when the sun is shining via a magic box built by @Dirtyshotya. The box dynamically adjusts hashrate based on the power received from the panels. I'll be tying the miner into the home's ductwork, so we'll put the heat the miner produces to use as well. The way I see it, I've prepurchased my electricity and will be repaid over time in BTC mined + reduced heating costs in the winter. Eventually I hope to also use the miner to preheat water going into the water heater. Repurposing the miner heat for as many tasks as possible will help reduce the ROI on this system. 2. I spent more time in the woodshop this week. I have a membership at a local makers' space and I try to spend a day there every week working on various projects. This week another member offered to spend some time teaching me how to use the cnc machine. We made a small serving tray. I look forward to digging deeper into cnc in the coming weeks. 3. Last week I built a hood to vent smoke outside when I roast coffee. In addition to roasting for Mrs. Bitmeyer and myself, I’ve been roasting coffee and trading it for BTC at a couple of meetups I attend. It was rewarding to give the hood a try this week. It worked quite well and my family was grateful that the house was relatively free from roast smoke. Plus, I get a lot of satisfaction from using something that I designed and built. Winning! 4. I’ve been working on a grid pattern for another project and I ended up with some sheets of paper that my family wanted to use as coloring pages, so we made it into a coloring contest, with each of us coloring our own page(s). We had a lot of fun making our sheets together. Now we have a small gallery that we are enjoying looking at. We called it a contest, but I think we’re all winners. https://m.primal.net/HaUP.jpg https://m.primal.net/HaXw.jpg https://m.primal.net/HaYF.jpg https://m.primal.net/HaYT.jpg npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger New world being built. #note1x6w…ny88 npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger dreamy npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger ELI5? npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger can confirm. this is the way. npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger nice. over here it's a washed Guatemala. nothing beats that fresh roasted goodness. npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger what beans are you pulling this morn? npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger ~2/3 of a shirt, at least npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger It might. npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger beautiful solution for beautiful axes. npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger Belief. npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger comfort food done right. 🔥 npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger Nutella npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger not too late. npub1vpx9596duxdsmx4kwksycm2u4qy0gr6mzg289m52q96gdy97s9zsnkjspj peacemonger I did some reading about it last winter and came to a similar conclusion.
