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. nostr:npub1f5pre6wl6ad87vr4hr5wppqq30sh58m4p33mthnjreh03qadcajs7gwt3z 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.
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.

yes, there is new issuance but the printing schedule is known, auditable, and decreasing over time.
Tearing out old tile. Some broke. most are still in decent shape. I'm thinking there should be some use for them. Do you nostriches have ideas?

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.

How do I view it? All I see is a bunch of gibberish.
Zaps to anyone who sends me screenshots of what nostr:npub1v0tfjv5ahr3c260jtzdk5w48krerrnkg8fmcnc5lpguk0qda04eqzm3m3e's marketplace posts look like on Damus. Trying to see how the different clients display them before I try to craft my own.
Are these the posts you're looking for?
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.
Bring back producers.
