12:23 AM rue_mohr: woof anyone have any disposable income?
12:23 AM rue_mohr: so far, the idea I'v seen that is interesting, is to put an encoder on the back of the servo, using the motor terminals as the anchors for the circuit board
12:29 AM rue_mohr: https://www.aliexpress.com/item/4000041694974.html
12:29 AM rue_mohr: those are used, SOMEONE scrapped a drone program
12:31 AM rue_mohr: https://www.aliexpress.com/item/32964227424.html
12:31 AM rue_mohr: hahahah
12:32 AM rue_mohr: scroll down, see schematic...
12:34 AM rue_mohr: wow, there are a lot of listings for those
12:52 AM rue_mohr: https://www.aliexpress.com/item/4001248047128.html
12:52 AM rue_mohr: hmmmmm
12:54 AM rue_mohr: https://www.aliexpress.com/item/1958810870.html <- if I were into burning money, I'd go for that
05:02 AM polprog: hmm
05:02 AM polprog: my fax/printer has got some pretty good spatial resolution
05:02 AM polprog: maybe i could try printing some encoder disks
05:02 AM polprog: i dont have transparent foil though
05:11 AM polprog: https://github.com/q3k/chubby75
05:11 AM polprog: so ive got two neat fpga dev boards coming in
08:50 AM rue_mohr: yea I'd like to know how to etch aluminum foil
09:25 AM rue_mohr: heh
09:25 AM rue_mohr: I'd never thought of this before
09:26 AM rue_mohr: but the comparator can be used as another interrupt source...
09:26 AM rue_mohr: have to try that one someime
09:29 AM rue_mohr: reset is adc0, so you can use that as the ref, and bring it down just a bit to compare against, huh
09:31 AM rue_mohr: 0.9vcc
09:32 AM rue_mohr: I gotta see that, I dont beleive it
10:25 AM aandrew: I went wild and bought like 10 of those pixel purses when they dropped to under $10
10:25 AM aandrew: so I have a bunch of their panels
10:26 AM aandrew: had to enlist a bunch of friends to help me get them becuase there were restrictions on quantity
10:58 AM polprog: whose panels?
11:27 AM rue_mohr: the pixel purses
11:30 AM aandrew: they're the same panels that your board can use
11:32 AM polprog: ah
11:32 AM polprog: i made some stickers
11:32 AM polprog: 28
11:32 AM polprog: er
11:32 AM polprog: bad paste
11:32 AM polprog: https://i.ibb.co/tzQKYZg/IMG-20201119-180755.jpg
11:32 AM polprog: i like these logos a lot
12:18 PM polprog: i made some stickers for the clipboard
01:32 PM rue_shop1: I have the blackberry mainboard
01:32 PM rue_shop1: the chips are unlisted samsung
01:32 PM rue_shop1: but those nand-flash chips, are completely packet based
01:33 PM rue_shop1: which sucks, might as well use dram
02:06 PM Tom_L: https://svgur.com/s/Rdo
02:06 PM Tom_L: pick one
02:06 PM Tom_L: favorite heat control
05:34 PM rue_mohr: uh
05:35 PM polprog: sup?
05:35 PM rue_mohr: truck is back from oil change
05:42 PM TermMoon: :P
05:47 PM Tom_L: still purrin like a kitten?
05:51 PM TermMoon: burbaling like a drowning cat
06:51 PM rue_shop1: ok
06:51 PM rue_shop1: I'v managed to use a sprint for a force sensor
06:51 PM rue_shop1: by making it the inductor in an osc
06:57 PM Tom_L: what's a sprint?
07:01 PM rue_shop1: spring
07:01 PM Tom_L: makes more sense
08:32 PM rue_shop1: I get about 50Mhz retracted and 62Mhz fully extended
09:17 PM Tom_L: huh
09:17 PM rue_mohr: its a nice strong ratio
09:34 PM Tom_L: https://formlabs.com/uk/blog/adding-screw-threads-3d-printed-parts/
09:34 PM Tom_L: since you print stuff
09:34 PM rue_mohr: hah
09:34 PM rue_mohr: not really practical on my machines
09:34 PM rue_mohr: they dont take the overhang well
09:36 PM Tom_L: i forgot what those thread repair kits are called
09:37 PM Tom_L: ahh.. helicoil
09:37 PM rue_mohr: :) yup
09:37 PM Tom_L: unrelated
09:42 PM Tom_L: i should figure out a project
09:51 PM Tom_L: did find my green stone
09:53 PM Tom_L: are those bend sensors bimetal?
09:58 PM rue_shop1: band sensors?
09:58 PM rue_shop1: bend?
09:58 PM Tom_L: like in those gloves
09:58 PM rue_shop1: not sure
10:10 PM rue_mohr: powerglove right?
10:11 PM rue_mohr: oh I'm supposed to try using the comparator on the t13 as an interrupt pin
11:50 PM rue_mohr: https://www.youtube.com/watch?v=qEu4g_wmlS4
11:50 PM rue_mohr: no gloves, I dont think a mask, wearing sandles...
11:50 PM rue_mohr: welding galvanized metal
11:51 PM rue_mohr: I got nothing on this guy
11:51 PM rue_mohr: I think its even a concrete floor
11:53 PM rue_mohr: chipping hammer doubles as a wrench..
11:56 PM rue_mohr: did... did he just use a 603 as a thrust bearing????
11:57 PM rue_mohr: ok does have a welding mask
