Yesterday I carded more Tunis, spun more Romney singles, and submitted a
progress report at work. P started investigating the circuitry in the
(sadly broken) Nixie tube clock, in prep for replacing the bad vintage IC
with a raspberry pi. Together we figured out that not only does the rs232
signal line not go over 5v, but it’s a simplex connection (the clock only
receives, never transmits), and he might be able to get away with just
plugging in the rx from the clock into the tx from the pi without having to
bypass the max-232 for voltage safety reasons. On further research I’m not
sure that will actually work, plus getting around the max-232 may not be as
daunting as we thought. After dinner I worked on Gerty’s embroidery project
and started watching On My Block, which is alright so far, and surprisingly
light for a story about teens coping with racism, gangs, sex, alcohol, and
all the other obstacles they encounter, on top of teenagehood just
generally being awful.
Really tripped-out dreams of house-sitting for a friend who unexpectedly
had a radio station auction off his house while he was still away. Also a
surprise collection of mannequins.
