i did not realize how fragile "sd card plugged into raspberry pi" is. my headmate's 3d printer server just... had an sd card die. it sort of reads except sometimes it spends half a minute reading a single sector

wtf

@foone @whitequark I’ve been doing a lot of tests with raspberry pi CMs, and building/testing with automation.

That kills about one “cheap” card a day, or makes a “reputable” regular one last maybe a week, before it starts dying like you describe.

Solution I found was buying high endurance, industrial-grade cards. First batch I got had been lasting 6 weeks now!

Here's something cool I never realized existed:

PCBs distributed through magazines!

@foone 15-20 years ago, UV photoresist was the “fancy” way of doing it in my uni in Brazil.

Usual one was, photocopy the design in the darkest setting to get as much toner as possible stuck to the page (thin paper worked best), then use a clothes iron to heat transfer it into a bare copper board.

Dissolve the paper in water, then throw the board into an FeCl3 solution to eat away the bare copper and leave the covered traces behind. Then scrub with IPA to clean it, and drill.

The worst part of digitization work is having to practice reloading the label printer blindfolded

@foone oh? why is that?

No “ambient” light so that only the scanner’s light is the source?

Worst idea: a smart TV with all the annoying online features and built-in unblockable advertising, but it's a CRT

@foone I mean, the first part is already the experience some are getting. With that in mind, I know people who would pay extra for the second bit, yeah!
