The acid in cider will aggressively dissolve any iron or copper it comes into contact with, giving it a blue/green color and corresponding taste. One thing I ran into with my old press was some paint finish flaking off, exposing the ir

Just finished looking into these more. While they seem really neat, even if I home-built one it would be way out of my price range. Just the filter belts alone would cost more than this entire project did.

This looks very promising, thanks! I sent them an email. I've never worked with anything higher voltage than 240V before, so having people with experience to whom I can ask questions will be very helpful. If it was 5v pulses, I could j

> customary to chuck an iron ploughshare into the cider fermenting vat; it would completely disappear by the end of fermentation. I have trouble believing that this was customary. It's absolutely the case that iron will dissolve in

To clarify, with the grinder I built described in the post, I did not have to cut open apples by hand any longer. It could shred apples as quickly as apples could be put on the ramp.

These are neat! I've been vaguely aware of them, but never looked into them too much. It's hard to find DIY plans online for that sort of thing, and I'm not sure I'd be able design my own from scratch well enough to be w

Hopefully by next year I'll have implemented the pulsed electrical field generator I mention at the end, and then I'll very much have solid-state electronics directly contributing to cider extraction.

I think it breaks down when you start trying to look at emergent behavior that only becomes apparent at large scale. An analogy would be to start looking at a water molecule, H2O, and then trying to explain glaciers and oceans without any s

Exactly. Better analogy- if I put some items up for sale in a consignment shop, and the shop owner doesn't lock the door overnight and someone runs off with all my stuff, I'm likely to be more upset with the shop owner than the ac

Wind turbines don't kill enough birds to be more than a drop in the dead-bird bucket. It's a talking point used by people who were looking for reasons to be against wind turbines, but housecats kill four orders of magnitudes- not

I'm not sure that's true. What you describe is the case for any individual candidate, but doesn't account for how those candidates interact with one another. Specifically, it has repeatedly been shown that more diverse teams

As mentioned elsewhere in this thread, this is a variant, not a strain. This variant does not have any genetic differences in the spike protein targeted by the vaccines. It is unlikely the vaccines will be differently effective.

Not really. The cost of sequencing was dropping slowly for a while, then dropped much faster than Moore's Law between 2007 and 2012. It has since dropped much more slowly.

Are sulfites thought of as generally being bad for you? I was under the impression they were pretty neutral unless one happens to be in the very small group of people who are particularly sensitive to them.

If we're going this route, every time someone builds something like this and shows it to friends, that's a tacit advertisement for IFTTT. IFTTT can also then place a monetary benefit on allowing users to make unlimited things like

That would be tremendous. Earth is 12700 km in diameter, so such an image would be a bit more than 500px across. Here is a picture of the Earth that is about 500px in diameter: https://cdn.mos.cms.futurecdn.net/3upZx2gxxLpW7

A huge number of the people on this site, myself included, already voluntarily donate huge amounts of time and money to free and open source software and hardware- they are already choosing to give away for free what others might otherwise
