Resilience. Abundance. Sovereignty. Human flourishing. These are a few of my favorite things. Roasting Otis Bitmeyer Coffee and sharing it with friends.

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? #asknostr #buildstr image

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 image

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.

To all my fans: Thank you. May the blessed richness of cheesecake envelope you in its sweet embrace. May your notes be wise and beautiful melodies that rise to blanket the earth with abundance. May you ride through life on the sofa that is the breath of divinity. And at the end of every day, may you take a few deep breaths to remember that you are already at the party. To all my h8ters: Thank you. May your Toaster Strudel always turn out a smidge darker than you prefer. May your DND games be dynamic and engaging. May empathy and compassion support and embrace you like a Sleep Number mattress set to the perfect firmness. May freedom and peace accompany you as gentle and comforting reminders that you’re already at the party. To all my ambivalents: What’s up. May your house be blessed with exquisite fine rices from all over the world. May your toothpaste always flow from the tube like slightly softened butter. May your work be strong, thoughtful, and just. And in those moments when you find yourself chasing thoughts through your mind, may you pause to remember that you’re already at the party.
