10:10 AM aandrew: oh man I love this idea: https://hackaday.io/project/185347-pcb-linear-motors-for-model-trains
06:59 PM rue_mohr: nana nice
06:59 PM rue_mohr: hahah nice
07:10 PM rue_mohr: 2613
07:11 PM rue_mohr: up in its and boops
07:11 PM rue_mohr: huh
07:57 PM Tom_L: .
08:00 PM rue_mohr: yea I'm here
08:00 PM rue_mohr: a bit
08:05 PM Tom_L: running low on motivation
08:34 PM rue_mohr: yea
08:35 PM * rue_mohr tips the bottle of motivation upside down and shakes it for a few more drops
08:38 PM Tom_L: you blocked the exit. the numbers keep going up
08:39 PM rue_mohr: hah
08:39 PM rue_mohr: I need to think up a mount to help with the injector
08:39 PM rue_mohr: its not clicking
08:39 PM rue_mohr: it will, but its not yet
08:40 PM Tom_L: i thought you had pegs on the side to mount it
08:41 PM rue_mohr: well yes, and thats got a handle right now
08:41 PM rue_mohr: but it requires 3 hands
08:42 PM rue_mohr: I need to have it mounted somehow
08:42 PM * Tom_L thinks rue_mohr would look funny with 3 hands
08:42 PM rue_mohr: I wonder, what if I set it against the mold with a foil aluminum barrier that breaks away when injecting
08:43 PM rue_mohr: would help warm the mold
08:43 PM rue_mohr: but
08:45 PM Tom_L: did the mold clean up ok?
08:46 PM rue_mohr: yes, the remaining bit I should be able to clean out with PS!
08:46 PM rue_mohr: there is a bit of stuff left
09:39 PM rue_bed: https://www.youtube.com/watch?v=78bM615koOo
09:42 PM rue_bed: ok
09:43 PM rue_bed: maybe I should have put a threaded connector on the nozzel end
09:46 PM Tom_L: would have been my choice
09:46 PM Tom_L: those molds look surprisingly similar
10:08 PM aandrew: so rue_bed what's the answer
10:08 PM aandrew: to your piston question
10:08 PM aandrew: isn't the air pressure going into both sides of the piston at the same time?
10:38 PM rue_mohr: yes, but there is an area difference
10:38 PM rue_mohr: because the shaft takes up some area on one side of the piston
10:38 PM rue_mohr: so it moves out
10:40 PM aandrew: ahh
10:40 PM aandrew: I was looking at the size of the piston on each side but failed to take the shaft into account
10:46 PM rue_mohr: :)
