My place to post silly pictures and rants, even though I’m no longer a PhD-student.

Playing with old junk, episode 756412
I found a nice a old HP 82240 thermal printer in the cellar once. You can use it to print stuff from those pretty HP reverse-polish calculators like the HP48. Unfortunately they only speak the proprietary red-eye protocol over infrared so I had to resort to a little bit of hackery using a AtmelTiny2313 and a IR-diode... And now, it prints! :-) Hooray.
