amogus-scale features now possible at fafo
(behold, the sharpie lift-off process: scribble your substrate with a sharpie, deposit Al, dissolve sharpie with acetone)

You! Yes, you, at #39C3 ! Come to our self-organized-session-talk thing!

Zoomed in, taken via external scan. Sorry, no scale, need to write/find a better conversion tool.

Today at FAFO: hitting rocks (in this case pyrite) with a hammer and then putting it under a SEM.

Hello!
Do you have too much money? Would you like to give us some of that money?
Well, we've got quite the news for you: we can now accept donations! And if you're in Germany, you can tax deduct them, too.
https://wiki.fa-fo.de/orga:donate
All of your donations will go towards our statutory goals. In practice that means you'll be eg. funding equipment and supplies for our DIY semiconductor research.
(note: we will _probably not_ spend this money on golden-plated gardena couplings)

You know, this actually isn't too bad.

Today our PDP11 learned its first important lesson: You need to FA to FO! Bare metal C code with a custom asm trampoline, no stdlib, cross-compiled for pdp11 from gcc-14.2 on macOS arm64, exported as a paper tape of all things, loaded via remote desktop to a windows machine that loads it via serial into RAM via the ODT mode. Almost just like in the old days. Almost.

nice and clean
(please ignore the slight surface rust issue on the o-ring mating surface)
(please also ignore the caked on tar on the core)
