Try Red Star - Montrachet, it was pretty solid.

This is a fine approach too. Just be aware that most modern mcu would be a hell to mount on DIY. Also, this works on literally any paper with super bold print setting.
I would recommend trying copper-based etch, it’s easier to work that FeCl3 (it’s transparent, to begin with, and not as corrosive to other stuff)
Also, I’ve heard some dudes made really nice stencils for paste with some cheap hobby blade CNC tools on cardboard, there are models that have orders of mad higher precision than advertized. Never tried this myself though, lazer cut stainless steel plates from factory are just soooo good (and also a source of high quality steel in a workshop when you don’t need them anymore, they make perfect wood scrapers and such)

Whoa, then I have a solution for you: get particular strong profile red wine yeast and throw it in white wine must! As easy as that!
I’ve made mead that tastes like red wine, and like white wine (and like mead too). It’s mostly the yeast, color is secondary.

oh, and do not be afraid of surface mount. It’s actually easier than it looks, especially if you were smart and did order a stencil (otherwise it’s a toothpick and paste, nothing too hard, just… so slow that paste will dry out).
paste recommendation: ChipQuick. Surprisingly, stuff from hobby shop works better than many professional products, even in professional settings. I had my team leaving spatula on stencil printer for months, just warm it up a but and it’s like new. Magic.

Eagle is dead. KiCAD is certainly the choice, both from starting hobbyists and for high level professionals. Order you PCBs somewhere, order stencil. Buy components yourself, solder yourself, make stencil holder from cardboard. Do not mess with assembly orders unless you’ve learned how it works at home. Get a fan and soldering iron, relly good tweezers (I recommend Tweezerman not made in China, absolutely best gear even though it’s made for other purpose, works for electronics and electron microscopy sample handling).
Really weird fact: AI is useful for converting datasheets into kicad models, sometimes even 3D. Finally some dumb menial task worth of AI - format conversion. That’s that those damn things should be used for.

Altium is nonfree shittyalternative for kicad by now. Don’t. Especially for hobby.

Actually I saw guys filtering red wine into white. You need something like sterilization filter (0.04 um) and tangential flow so that it does not clog. We all should start using tff technology, it’s just so awesome.

From my experience, sqeezing fruit pulf through filter just makes coagulation harder. Just leaving it in fermenter for half year or more results in laser clear fluids upon gentle decantation.
- Comment on Lemon, ginger and lemon balm beer 5 days ago:
These mad plants crawl everywhere. Sure, I have those bonsai trees I care for, but spending this much effort on a grass seems a bit mad. I’ll try to grow it a winter garden. I think the edge of native grasses comes mainly from winter fungal activity under snow that they somehow benefit from; if I manage to exclude that from local system, things might change.
- Comment on Lemon, ginger and lemon balm beer 5 days ago:
Somehow, this plant gets mauled by local grasses in my garden. I’ve tried growing this weed many times, sourcing from different places - I had experience with mint relatives as being super invasive - but every year, it just doesn’t stand to competition here. Savo biomes are mad.
- Comment on Lemon, ginger and lemon balm beer 5 days ago:
Drying is usually not so much matter of time as matter of OG and yeast strain. OG1090 mead dries to completeness faster than 1120 going to medium (and then staying there forever). With beer, it’s harder to pintoint the turning point, as beer yeast is much more diverse. There is also matter of non-fermentable sugars content that will never disapper. And you’ve got to have vigorous healthy fermentation to make it in time to bottle with enough active yeast if you plan natural carbonation.
- Comment on A spruce and a mushroom 3 weeks ago:
Actually I’ve seen scientific papers that did just that - hydroponically kept a root alive until full colonization. I wouldn’t attempt that, I have plenty of actual living forest to mess with this extremely complicated system in a jar, knowing it is possible feels enough, pushing it further is not worth the effort. At least now.
- Comment on A spruce and a mushroom 3 weeks ago:
They actually sell seedlings inoculated with mycorrhiza I think. My wife speculates, that too vigorous mushroom as they get in monotubs will totally turn from symbiotic to predatory, as is customary in this world.
- Comment on A spruce and a mushroom 3 weeks ago:
Yeah, was surprised as well, but it looks correct and they grow locally a lot. I’ve seen fruiting body growing smaller than normal in my constrained growing experiments (but also larger than normal sometimes).

- Comment on Can a Russian pls confirm 4 weeks ago:
As native Russian speaker, this is terribly rarely used in this full format (and it’s one among many), but genuine, I’ve heard it IRL.
“Тебя не ебёт, так не подмахивай”
This is highly and universally derogatory, you could expect to hear it from lowlife/criminal, which, unfortunately, is what most russians are lately, though. For russian nazi population, this implies that you are gay or a slut, depending on biological sex, and that’s close to your life worth nothing. For the rest, this is just something nazies would say to insult you.
The first part alone, though, is quite socially acceptable and overused. I guess, because it’s lost the whole lore behind it, and showing your knowledge of whence it came from kind of reveals that it’s not just an empty word, but you mean it.
I’m a bit hyperfocused on swearing, am I? Was one of my childhood’s special interests.
Honestly, “mind your beeswax” is also a rare gem, but not quite so rare.

I do not have a lawn, I have several ha of forest and grassland. I have about 25 nest boxes for wild birds, occupied 2/3 (last year I had a huge owl living in one!) and countless other nests, several snakes, snails and frogs, lynx and I see bear tracks and scats now and then. I keep bees and allow wasps to build wherever they like, there are lots of bumblebees everywhere and birds sure have something to eat. I mulch a lot and keep loads of rotting leaves. I mow with scythe when I absolutely have to clear small area. I know there are fireflies in Finland.
Never saw a single blink.

I’ve seen them once in my life, in Smoky Mountains, about 10 years ago. It was pretty much spiritual experience. The darkness came alive. I cried when I saw their luciferase smeared over windshield and glowing long after the creature was dead. I knew lots of lore about them, saw them in mass culture - never realizing I never saw one myself, even though I take care to notice all living things around, from bacteria and yeast to mycchorizal networks.
I live in Europe.

- Comment on Spruce tip beer ('tis the season) 1 month ago:
Overcooled sugar syrup (what people usually make by heating sugar in water and then cooling down) would technically be a suspension of sugar nanoparticles in saturated syrup. This should totally be more potent for chemical extraction than pure sugar, even after extraction of fluids into it which could only saturate it into syrup phase.
Throwing alcohol into beer preparation souds like illegal move in Finland an USA afaik, LOL

- Comment on Spruce tip beer ('tis the season) 2 months ago:
I don’t really think they heated that much, it’s oven temperature, and water was not driven away.
I think you are correct on “melting” part.
- Comment on Spruce tip beer ('tis the season) 2 months ago:
Awesome design! I’ll drop a few thoughts on it.
Darkening is just sugar caramelization accelerated greatly by acidity of tips. Just a small pH drop in moisture - and tips are tart - accelerates the process by orders of magnitude.
With high temperature, you lose some volatile stuff unless you have it all sealed (which itself is explosive). I think you can achieve similar extraction by alcohol groups (that’s what sugar does) by adding tips in secondary. But then you won’t have all this caramel. Caramel could come from specialty malt or sugar caramelized separately. Anyway, overdefined problems are just more refined tools for future experiments!
Was this tips extraction simple? And filtration?
- Comment on Getting serious now 2 months ago:
The main use of heaters in this setup is to make the “spring” of oscillatory heat system “stiffer”. This should make temperature oscillations faster and smaller in amplitude thus bringing process to more stable state. This is mostly important when you have set temperature close to ambient outside, otherwise you’ll inevitably leak a few watt through fridge insulation anyway, and if it’s not enough you can always prop the door open. Latter would lead to humidity buildup though. If you set process to 20C, obviously, no leak, huge slow oscillations on heating phase.
Then there is diacetyl rest, I’d just recommend taking that thing out for that.
