It's a 2-fer today.
I'm trying to make my own PCB at home, yes I know at this point I could have paid to have thousands made but that's not the point. I've come to the conclusion that milling isn't consistent enough, blowing away black paint with a laser isn't consistent enough so it's time to do photoresist. Expose the coated board through a transparency with a 405nm near-UV light and VIOLA, etch resist, then just etch. Being me, I decided I'd do the exposure with a laser directly as it would be less fiddly than printing stuff and aligning it. Of course I don't have as 405nm laser, and my 450 would almost work but would be right on the edge of scorching the etch resist rather than exposing it. So, found one 500mW module on eBay, ordered it, hooked it to power, plenty bright even through the goggles. Then hooked it to the 3d printer I was retrofitting, not so bright. Thought it was PWM settings, no, all good, fucking thing burned itself out in the hour I tested it. Not worth anything but throwing it away. All the other ones are from China, so I ordered one of those, let's see how that goes when/if it ever arrives. At least my Chinese crap usually lasts more than an hour.
My friend agreed to let me put a small backup server at his hangar if I paid for an Internet connection. So I ordered it and was careful to say "Cheapest Internet" no Wifi, no other crap. Install is later this week so they sent the preliminary bill, top tier Internet, Wifi and a phone line. Now I gotta call the fuck again and explain that planes don't make phone calls and I already have plenty of Wifi gear and routers. Fucking Internet companies.
