occasionally push it to near boiling temperatures.

So I’m guessing you have some kind of mixing valve set up to handle this going out? Also, are the tanks rated to that high of temperatures?

That’s probably most similar to what we’d call “flaked corn”, but it’s not something that we see commonly in stores (in America, at least). It is somewhat similar to “corn flakes” which are different.

It’s mainly used for brewing and distilling, and it’s made by taking dry corn, partially cooking it with water, putting it through a roller mill, and then drying it out.

Reading about farinha de milho, it actually might be similar to “corn flakes”, though. It’s a breakfast cereal made by taking ground corn and cooking it in water, and then drying it out in little sheets. It is super common to use as an ingredient in things like fried chicken batter, or as a topping to things you want to be crispy.

I’ve taken up bringing an instant read with me when I expect I may have to cook at someone’s house. Nothing worse than trying to make a prime rib at someone’s house, a getting handed one of those analog dial thermometers that doesn’t even have numbers on it, just “rare, medium, well done”.

For ground beef, especially, too many people try to chop it all up and get it “gray”. I don’t eat beef often, but when I do make ground beef, I basically treat it like making a hamburger: salt it immediately prior to placing in a hot pan, and don’t touch it until there is browned crust, and then try to flip it and get a crust on the other side. Only then will I break it up into little pieces. If you have too much meat to do that, you are better off getting a good sear on half of the meat, and tossing in the other half later, than trying to do all of it and basically just boiling the meat in juices.

occasionally heat the tank up to 70°C+ to kill off any bacteria that might be growing in it.

Is that a built in function of your fancy water heater, or is that something you just go do periodically as part of maintenance?

I’d love to get one of those heat pump water heaters. Seems like a win-win to dehumidify the space.

I’ve read that red variants of veggies like cabbage get less attacked by caterpillars, and anecdotally, it seems to be true. It makes sense that insects would be evolved to target the more “natural” color.

Here is a really good article about the topic. The gist is that typically in mountaineering, there’s not often an official definition of the “start point”, but the “end point” is back at the start, so people who die midway on the return journey don’t “count”. The “top” should be easy to define, but often, the top of a mountain is a large area, and you aren’t going to hike around looking for which part is just barely the highest. Also, some true summits are habitually avoided as sacred places to the locals.

I think it ends up being the same amount of work for me. Rinse rice (optional), figure out correct amount of water for that type of rice, place on heat until done. Rice cookers can effectively detect that there’s no more liquid water, but that isn’t the same as “done” unless you used the right amount of water.

IMO, rice cookers are really handy if you are the type of person who eats rice as a staple food item that you buy in giant sacks and eat the same variety of every day. I have like 6 kinds of rice I rotate through, so I think it wouldn’t save me enough work to justify a separate gadget.

I’ve never used one of the really fancy pressure cooker rice cookers, though, so maybe my feelings would be different.

Yeah, I definitely understand that. I certainly have things that I don’t use as much as I hoped (I’m staring at a solar panel doing nothing leaned against my wall). For me, I really need the resulting “thing” to be something that I will use/be excited about.

That’s why, for me, fixing stuff that’s broken, upgrading stuff, or repurposing stuff you already own is good. Replacing a worn out jack is a relatively simple task that can turn an expensive brick back into a nice thing.

The tools you need are not a very long list. You can get a cheap, crappy soldering iron for $6, solder for $4, a crappy multimeter for $7, and one of those magnifying glass/alligator clip things for $6 from harbor freight. Despite being poor quality, a lot can be accomplished with just those tools.

I ended up buying a bench power supply for like $40, but you can just get DC power supplies from the bin of assorted cords at your nearest thrift store for basically free.

Wow, you couldn’t be more different than I am. Over the years, I’ve bought kits that had tutorials along with them, and I could never get hooked by them. I guess there’s better tutorials for things now than “make a bunch of LEDs blink in order”, so maybe the terrain is different.

There are so many kits you can find online, and I think a lot of them are more or less interchangeable. I suppose it depends on what extent you want to focus on digital vs analog circuits, but given that you mention robotics, I would assume digital. Grab one of the kits that has an arduino or raspberry pi and a bunch of other components. In the grand scheme of things, components are cheap, but no one is going to ship you the 5 exact resistors you need, so you need to have a fairly large assortment to choose from for different projects. Kits are going to come with different components like digital readouts, joysticks, etc, so just choose one that looks like it has the things you would like to learn to use.

It seems like kits are divided into “contains every part of a specific project” or “contains parts for 1,000,000 potential projects, and here’s a booklet of tutorials for some”. I prefer the second, but you could prefer the first depending on if you want to go right for robotics use cases.

Personally, my best learning has been through repairing home appliances and stuff like that. Even just “necropsies” on broken things to understand how they work.

Something that you’ll notice with electronics these days is that sometimes the difference between a base model widget and the “premium” widget that is 1.5-2 times the price is the addition of a handful of cheap parts. They might be easy to put in and cheap, but they are going to remove as many costs as possible for the base model. For example, a $350 dollar espresso machine with $100 of extra parts added can easily compete with a machine that costs $1000 or more.

I guess maybe it’s been a while since I’ve looked, but that soldering iron seems like a crazy good deal. I’ve been using a crappy iron with a way too stiff cord for the longest time cause I figured it wasn’t worth it for how little I have to solder.

If you wanted pizza to be “italian”, it would have to have no tomatoes, peppers, pepperoni, buffalo milk cheese, basil or a whole bunch of other ingredients that are commonly added to pizza.

Pizza is a global food, do with it as you will

They try really hard not to explain how the system works. It doesn’t mention it at all in this news story, or anywhere easy to find on their site. I crunched some numbers, and it seems like this device has about double the heat capacity for the mass than just plain water would have. That means it probably has to be a phase change material. All of the “smarts” and app control is nice, but at its core, it’s really simple concept. I think this kind of thing would sell better if instead of trying to make it sound high-tech, they just admitted it was a low tech solution that they’ve made user friendly.

I did find this mention in the site q and a:

Q: What is the storage medium made of?

A: Proprietary mix of high-density, inert, non-toxic and low impact materials

I don’t understand why people like Facebook marketplace. It’s so transparently a way for them to just gather more shopping habits data on you, and it’s too easy for scammers to use. They act like having an account somehow makes it harder to scam.

I would much rather support the website run by a skeleton crew that has no unnecessary features than get a few bucks more on FB marketplace. If I’m selling something that I’ve used, it’s cause I want to get rid of it, anyway.

Oculus was founded by a shitty person who sold to Facebook and then went on to help make a company to bring Big Tech into surveillance and autonomous weapon systems. Basically, he’s trying to bring on an orwellian nightmare.

Oculus would have gone bad weather or not Facebook bought them.

Yeah, freezing water is definitely great. It’s just a little trickier to deal with since you need to account for the expansion, and the fact that you can’t pump it around anymore.

A huge problem with the wine industry in America is that they’ve always tried to position themselves as a premium product with respect to other forms of alcohol. With respect to the information available to the consumer, the pricing seems to be random. Products that are aged understandably are going to cost more, and huge brands should be cheaper than small brands. Other than that, prices just seem to be set to correspond to whatever market segment they are targeting. A $20 bottle of wine may taste way better than a $15 bottle, but it could also be worse. There’s no indication of what could make the $20 bottle better than the $15 bottle other than the fact that it’s more expensive. Some brands put a little bit more info in, like the percentage of grapes, and sometimes they tell you where the grapes came from, but most consumers are just going to grab the cheaper bottle.

Contrast this with beer, where you know higher abv=more ingredients=more expensive, aged beers are more expensive, and beers from smaller or foreign breweries are more expensive. Breweries often tell you the exact ingredients that went in, so you can get a decent idea of what a beer will taste like before ordering, and you can make an informed decision to buy slightly more expensive products.

Wine is a little more tricky because there are fewer ingredients, and less processing, but they could absolutely give way more info. The wines that are good just try to market it as the magic of terroir in a bottle, rather than actually pointing out how and why they are better or taste different.

Coffee beans aren’t beans. There are some beans that are roasted as a substitute for coffee, like the seeds of the Kentucky coffeetree. In times of shortage, people have tried many things to replace coffee, like dandelion and chicory root. For the most part, the substitutes arent as good as the original, so people don’t stick with them. There’s a chance someone has tried to roast and brew pinto beans or whatever, but they probably taste bad.

Yeah, this should really be the future. There’s a lot of unnecessary materials used/energy wasted to give us our current “all power costs the same all the time” system.

According to this, about 70% of US household energy use is heating/cooling the space, or water. Much of that can be time shifted. What can’t be time shifted can be stored in cheaper ways than battery storage.

1 tonne of rock heated (or cooled) 20° C above ambient is a store of about 4.7 kWh. According to that same site, the average yearly energy use in the US is 10500 kWh. If 70% is heating/cooling, that’s about 20 kWh per day, so you’d need about 5 tonnes of rock to hold that enough energy. That seems like a lot, but it’s just about 2 cubic meters of rock.

If you use water, it has 5 times the specific heat (but less density), so you only need 1 cubic meter. Probably easier to heat/cool/use, too. Water can also be heated more than 20 degrees above ambient, too.

Really, we should create incentives for homes to be built with high thermal mass. Even without any sort of fancy direct heating or cooling of a thermal mass, it will store significant heat.

Yeah, if you watch a video on old water powered mills, they had all sorts of transmissions built out of wood, including clutches to turn on and off the power.

The headlight thing is really cool
