12:11 AM aandrew: boo
12:19 AM aandrew: my power supply failed to come up on first try
12:19 AM rue_mohr: ?
12:19 AM rue_mohr: power supply?
12:28 AM rue_mohr: hmm
12:28 AM rue_mohr: does it give you back a pulse code?
11:24 AM polprog is now known as eggprog
11:32 AM eggprog is now known as elfprog
03:53 PM miss0r: I'm digging through my 'junk pile' to see if I can locate a TL431. What would be my best bet to look at?
03:55 PM Tom_L: the one with the TL431 in it
03:56 PM miss0r: :]
03:57 PM Tom_L: don't bother looking in the one with carburetor parts
04:04 PM miss0r: Just my effin' luck! I Found one, desoldered it and dropped it walking from one workbench to another. It went skip bonk and vanished into thin air !
04:04 PM miss0r: I've now been on my knees with a flashlight for 5 minuts
04:10 PM miss0r: Bleh ! I give in. Looking for another one
04:42 PM elfprog: i guess im fixing the milk frother tomorrow
04:42 PM elfprog: grandpa flooded it in water accidentally, it blew up a fusable resistor
04:42 PM elfprog: the microcontroller brains seem to be working ok tho
04:42 PM elfprog: which is good
04:43 PM elfprog: apart from that it's just a simple 5V smps and a relay to turn on a heater
10:01 PM rue_mohr: hi
10:02 PM Tom_L: hi
10:08 PM Tom_L: what sprocket ratio will drive those once you get them on the pipe?
10:08 PM rue_mohr: 1:1
10:08 PM rue_mohr: their the drive chain sprockets
10:09 PM Tom_L: yes but i figured those would go on each pipe and be driven by a reduced motor or such
10:09 PM rue_mohr: they pull the carriage
10:10 PM Tom_L: so 4 corners of a platform on rails connected with chain looped around those
10:10 PM rue_mohr: i dont have anything worked out to drive the shaft their on yet
10:10 PM rue_mohr: yea 2 chains
10:10 PM Tom_L: you could drive the chain itself and have that act as a type of tensioner
10:11 PM Tom_L: (____^____)
10:11 PM Tom_L: __ chain
10:11 PM Tom_L: with the top looped around the sprockets to the platform
10:11 PM rue_mohr: hmm
10:12 PM Tom_L: an adjustment on the motor or spring for tension
10:12 PM Tom_L: you may need more teeth engaged than that will give you
10:13 PM rue_mohr: my leading idea was to drive the gang shaft at each end,
10:13 PM Tom_L: unless you enhance the loop somehow
10:13 PM rue_mohr: opposing, to take up play
10:14 PM Tom_L: a 3rd shaft between with a tensioner and the motor on the end of the shaft
10:14 PM Tom_L: driving the chains
10:15 PM Tom_L: or a motor with the shaft out both ends extended with a tube or bar
10:15 PM rue_mohr: I dont mind driving the shafts
10:16 PM rue_mohr: I just dont have a reduction set to do it with yet
10:16 PM rue_mohr: but I dont even have mounts for those pillow blocks
10:19 PM Tom_L: https://i.ytimg.com/vi/LXfWWEwZMZc/mqdefault.jpg
10:19 PM Tom_L: something like that was my thought
10:19 PM rue_mohr: yup
10:19 PM rue_mohr: I hav a gang shaft to connect both ends tho
10:19 PM rue_mohr: cause its DC servos
10:20 PM Tom_L: except the chain would move instead
10:20 PM Tom_L: at least i think that's what you're doing
10:20 PM rue_mohr: yea, like a tank
10:21 PM rue_mohr: I should have used my holiday time to have taken this week off
10:23 PM Tom_L: https://www.alibaba.com/product-detail/Industrial-use-machine-parts-custom-steel_62056080228.html
10:31 PM Tom_L: some guy my kid knows wants them to work the weekends running his waterjet cutting granite
10:31 PM Tom_L: $30/hr
10:32 PM Tom_L: he already works 6 days
10:32 PM Tom_L: 5.5
10:32 PM Tom_L: at his regular job
10:33 PM Tom_L: the other one just finished hvac training
10:33 PM Tom_L: had a cnc job but covid ended that for him 2x
10:34 PM rue_mohr: hmm
10:34 PM Tom_L: the classic dilemma of no money or no time to spend it
10:35 PM rue_mohr: yea, I'm trying to see my balance from a 3rd party
10:35 PM Tom_L: a govt program paid for his hvac since he was laid off due to covid
10:35 PM rue_mohr: I reallly suspect I'm supposed to have worked out a fancy way to make money by now
10:36 PM Tom_L: at this point i'm just riding it out
10:37 PM rue_mohr: https://twitter.com/tobbelobb/status/1473344630842445832
10:37 PM rue_mohr: uh wow
10:37 PM rue_mohr: itmust be using a camera for positon feedback
10:38 PM rue_mohr: thats what the circles with the squares are
10:38 PM Tom_L: you think??
10:40 PM Tom_L: seems pretty steady
10:40 PM Tom_L: for being hung with string
10:40 PM rue_mohr: https://twitter.com/tobbelobb/status/1466773203938852870

10:46 PM Tom_L: so if i go now i might get 6hrs sleep
10:47 PM Tom_L: haven't done much messin last few weeks. need a project
10:47 PM rue_mohr: im between too
10:48 PM Tom_L: could tweak on the mill to try and get it more true but that's more like work
10:49 PM Tom_L: and the closer it gets the harder it gets to improve it
10:49 PM Tom_L: winter isn't really the time for that
10:49 PM rue_mohr: good to have a project
10:51 PM Tom_L: right now, i'm gonna sleep on it.
10:51 PM Tom_L: gnite
10:51 PM rue_mohr: ngiht
