I figure the increased power getting to the etching process also helps increase throughput. I’m guessing that you only need a total amount of energy to do a unit of etching work, so with more power you can do more units of etching work per unit time.

Per 2 hours even! Makes that 1500 hours

Yeah, I’m with you there, not sure what they mean by that

A/an before a word is dependant on how the subsequent word is pronounced, not spelled. So for that sentence, the implication is that it’s pronounced closer to “erb”, thus “an” to precede instead of “a”. Another example that’s a bit counterintuitive is “one” being pronounced like “won”, so you’d get “a one time thing” rather than “an one time thing”.

I don’t mean to poo poo FreeCAD the way I say this, but the vast majority of those features listed are bog-standard cad suite features at least by modern standards.

I’d love to see a FOSS cad suite kill my personal dependency on proprietary solutions, but as best I’m aware the UX is still hugely lacking.

SCUBA, LASER, JPEG, ROM, etc. all break the “pronounced as the nested word” argument.

I’m down for people to pronounce it however they please (assuming it’s recognizable as gif), but the post-hoc rationalizations trying to prove their side as the one true pronunciation are silly. The only rationalization that makes any sense to me is the “creator pronounces it as jif”, but language doesn’t work that way so even that doesn’t matter as far as “one true pronunciation” goes.

The LEDs don’t particularly (unless it’s a very powerful one), their power supply does though. LEDs run on DC voltage, so they need a converter from the AC line voltage to not die instantly
