tempted to just say fuck it and stick lead-acid batteries in there all over the place. oof

we don't know enough about magnetics to be comfortable winding our own transformer if it's going to be carrying a nontrivial amount of power

what we know: we need at least 750mA (call it an amp for headroom) at 15V

this is not hard, get a 14V or 16V AC source (transformer) and rectify etc.

but we have reason to believe we may also need a nontrivial amount of current at 5V, and I don't exactly want to be dropping 15V to 5V at like 2A in a linear regulator, so do they make transformers for 14VAC to 5VAC at 10-ish watts, or something like that?

trying to design a power supply when you don't know how much current you're going to need, and when you're concerned about efficiency, and you absolutely have to make it linear (noise would mess up research stuff)... fun times

three is a good number of eyes to have.

Apparently non-lead-free plumbing solder is usually 50/50 tin-lead. I wonder why that is, when it's so far from eutectic? Electrical solder is almost always either 60/40 (a simple ratio close to eutectic) or 63/37 (exactly eutectic).

*thinks for a moment, then emits a beep with a 432Hz fundamental and particularly pronounced second, third, fifth, eighth, thirteenth, and twenty-first harmonics, lasting exactly one second*

megamon, gotta get equipped with 'em all

finding industrial liquid cooling systems is surprisingly hard because all the easy search terms lead to them being buried in PC and server liquid cooling

one of the best ones we've found yet is marketed specifically for use in brewing beer

*taps the internet* is this thing on

*imagines trying to build a DC-DC converter using GTO thyristors*

That sounds like an interesting challenge--wait no why am I thinking about this that's a really bad idea

The great thing about about language is that you can just make up new words and no one can stop you

Boron!

the plot of PMD TDS wouldn't be too out of place in an anime, come to think of it

Starts out all focused on friendship and the power of working together, and then by the end of it you're trying to stop time itself from falling apart while the god of time, driven mad by time's crumbling, fights against you

question: can anyone recommend us a cheap, reliable bluetooth adapter preferably in the <$10 range but a little more is also okay?

PCIe or USB is fine but I suspect USB ones will be cheaper in general
