06:24 AM Tom_L: morning
07:40 AM polprog: https://polprog.net/rozne1/ircjunk/various/can_xfer.png
07:40 AM polprog: i was playing with elm327 yesterday
07:40 AM polprog: it exposes a telnet interface with AT commands
07:41 AM polprog: rue_mohr: oh you moved servers?
05:42 PM rue_mohr: polprog, no, aandrew wanted a full-resolution server
05:43 PM rue_mohr: aandrew, no, I was told its a bit trickey to master
05:44 PM rue_mohr: polprog, the 3d printed 144 led one?
05:44 PM rue_mohr: er 64
05:45 PM Tom_L: still alive rue
05:46 PM Tom_L: made it out of Honduras in one piece
05:53 PM rue_mohr: ok
05:53 PM rue_mohr: missed him, damn
06:47 PM aandrew: he's the Pokearoo
06:47 PM aandrew: you probably don't get that reference, it's from a kid's TV show from Ontario
06:49 PM rue_mohr: na, we didn't get that one here
06:50 PM rue_mohr: so, the usa is at the book burning stage
06:50 PM rue_mohr: I really wish I'd thought to make a bingo board for the fall of the USA
07:07 PM rue_mohr: its been a brain exhausting day
07:23 PM aandrew: hm
07:24 PM aandrew: I already have green photoresist... I guess I want UV soldermask
07:26 PM aandrew: https://www.aliexpress.us/item/2251832781695354.html
07:27 PM aandrew: now why in the hell would you ship light-sensitive chemicals in light coloured plastic containers
07:28 PM aandrew: I have to first see what the UV photoresist I have is like, it might work well as both an etch resist and a soldermask although I doubt it since acetone will remove it
07:32 PM aandrew: hm
07:32 PM aandrew: https://www.aliexpress.us/item/3256801595257701.html <-- that's what I have, that is marketed as soldermask
07:32 PM aandrew: have to try it but it seems like this would be problematic to remove if used as etch resist
07:38 PM aandrew: hm, sodium bicarbonate solution to wash away the unexposed resist, then lye solution to remove the hardened soldermask. I don't think lye does that with real soldermask
07:45 PM aandrew: s/bicarbonate/carbonate/
10:47 PM rue_mohr: hmm
11:49 PM aandrew: hm, I should buy some nichrome wire
11:59 PM rue_mohr: an old hair dryer from the second hand store
