  • It’s actually almost a thing - in Moscow State University, during world cup a decade ago, lazer show was projected right onto students dorm. Not that students didn’t protest, it’s just those who did were taken by police. Not to mention that many students had babies, and few were fans of loud noises or football for that matter. Fortunately these people were smart enough to save their eyes. Oh, good old stories from hell.







  • This is a fine approach too. Just be aware that most modern mcu would be a hell to mount on DIY. Also, this works on literally any paper with super bold print setting.

    I would recommend trying copper-based etch, it’s easier to work with than FeCl3 (it’s transparent, to begin with, and not as corrosive to other stuff). Edit: remember to wear goggles, all these things really destroy eyes on splash. Wash eyes for at least 15 minutes with running water if got it there.

    Also, I’ve heard some dudes made really nice stencils for paste with some cheap hobby blade CNC tools on cardboard, there are models that have orders of mad higher precision than advertized. Never tried this myself though, lazer cut stainless steel plates from factory are just soooo good (and also a source of high quality steel in a workshop when you don’t need them anymore, they make perfect wood scrapers and such)



  • Eagle is dead. KiCAD is certainly the choice, both from starting hobbyists and for high level professionals. Order you PCBs somewhere, order stencil. Buy components yourself, solder yourself, make stencil holder from cardboard. Do not mess with assembly orders unless you’ve learned how it works at home. Get a fan and soldering iron, relly good tweezers (I recommend Tweezerman not made in China, absolutely best gear even though it’s made for other purpose, works for electronics and electron microscopy sample handling).

    Really weird fact: AI is useful for converting datasheets into kicad models, sometimes even 3D. Finally some dumb menial task worth of AI - format conversion. That’s that those damn things should be used for.
