its not so bad now with the longer screws in the motor platform, everything tight w/ loctite
like, i could maybe program it so it resets I at TDC
and then a dead zone

because the gearbox has a few degrees a slack, and it just sits there ping ponging it back and forth
also i should prob put some mass on the end of the beam to slow it down
get a tennis ball so its less deadly
its like, smacking the edge of the beam hard enough the aluminum is slowly pounding itself into a point
yeah but this a cheap project, its doing pretty good considering
if i had $$$, something with tight timing belt gears would be cool
then the reversals wouldnt matter so much
one set of pid parameters, it actually felt damped and was mostly upright
but yeah shit was spazzing out

yeah maybe
i dont want to do that
this seems to be a typical issue with the normal hal uart rx function
but there is also interrupt and dma versions of the function, which seems to be normal solution
right thats basically what the HAL_UART.._IT and HAL_UART.._DMA functions work
its also how the normal one works but i guess if you interrupt it misses timeout ticks or something
and/or rx bytes get clobbered
shrug
who knows maybe something stupid
i maybe have to hard code some pwm disable when its like +/- some angle from target

soon
for some reason only 1st byte of uart rx is happening
fuck hal
i think it fucks up and misses shit if interrupted by an interrupt
and i have a 256hz sample loop
always gets the 1st byte okay
going to try and do it with dma shit, because i wanted to learn that anyway
but like, as is i can put the pid parameters in firmware and spray a terminal with runtime data
which is fine, i can just set terminal to log, then i can get plots and figure out transfer functions

so neat my inverted pendulum is inverting
my shit like the d but too much and it starts having junkie shakes

i will concede he is a product of los angeles media culture
got he would be even creepier
assume zero molestation, that guy had issues
no therapist has anything to reference
its very likely he was drugged when he did shit
yeah i dont know, dont want to know details
that family is all sorts of messed up, everything 'known' is what they say about each other
he had groupies and sang love songs, was maybe 7 or 8?

i dunno maybe because i had seen something as a kid
uncle was super into them
that was kind of the point of the sex pistols
like, gotta be offensive on all fronts, gotta have offensive band mate
well sure but being a tool works
right, and the sex pistols is basically 14 year olds
rotten is interesting
but like, i <3 the clash
the clash could have learned every sex pistols song in a couple hours
does not work the other way
rotten is smart
or it turned him smart
maybe jero would like gg allin
alin?
naw i was right
