11:09 AM polprog: https://www.youtube.com/watch?v=0SfqxTQpakU
11:09 AM rue_mohr: polprog,
11:10 AM rue_mohr: I was playing with optic isolation
11:10 AM polprog: what did you make?
11:10 AM rue_mohr: by the time its all said and done, the freq responce of the transformer is a bit flatter, and WAY simpler
11:10 AM polprog: heh. theres a reason they use those
11:10 AM rue_mohr: for the amp
11:10 AM polprog: watch the video
11:11 AM rue_mohr: heh
11:11 AM polprog: :D
11:11 AM rue_mohr: was that this mornings project?
11:11 AM polprog: yeah
11:12 AM polprog: watned to test (and terminate the cables) on a mikroma clone of the teac stepper
11:12 AM polprog: i love those
11:12 AM polprog: they are so useful! not sure about the torque
11:12 AM * flyback has a canuckload of old steppers
11:12 AM flyback: vexr 2 phase etc
11:12 AM flyback: japan ones
11:12 AM flyback: I think they all need taken apart and both ball bearings replaced
11:13 AM flyback: cause they are 20-30 yrs old and ate toner
11:13 AM flyback: but otherwise mint
11:13 AM flyback: all metal
11:14 AM polprog: hmm, i should take this one apart
11:14 AM polprog: i dont recall if i did
11:14 AM flyback: polprog, before you do
11:14 AM flyback: mark both halves of the body
11:14 AM rue_mohr: oh no, the new twitter does not have a translate button
11:14 AM flyback: so you don't misalign the magnetic fields or however that went
11:14 AM polprog: ive taken those apart previously
11:14 AM flyback: most of mine are minbea astrosyns
11:14 AM polprog: iirc those have a shaft that is separate, the body is just plastic + chassis
11:15 AM flyback: I have this one sanyo stepsyn if you spin it even without a load it sings
11:15 AM flyback: 30v on one o the two coils
11:15 AM flyback: make a hell of a gen
11:15 AM flyback: I had a big metal fan blade attached to test but I don't trust that in a neighborhood
11:15 AM polprog: and the coil assembly is a plastic tube that's filled wth potting
11:15 AM polprog: LOL
11:16 AM flyback: I also have this one stepper that ran the entire laser printer
11:16 AM flyback: the printer got flooded so I had to toss it
11:16 AM flyback: but kept the stepper
11:16 AM flyback: I just have 0 skills to make wind blades
11:16 AM polprog: yeah i took both apart
11:17 AM polprog: https://twitter.com/polprogpl/status/1053988649606541315
11:17 AM flyback: or figure out how to make 2 different shafts line up
11:17 AM flyback: and mount
11:17 AM polprog: https://twitter.com/polprogpl/status/962044609206497280
11:17 AM flyback: so my windmill dreams have sat for decades
11:17 AM flyback: oh nice one
11:17 AM flyback: that''s defintely worth rebearing
11:17 AM polprog: yeah, thats why i say they are awesome
11:18 AM flyback: you got a bearing puller?
11:18 AM polprog: nope
11:18 AM polprog: but they are okay
11:18 AM rue_mohr: polprog, I have a bunch of international people I'm following, now there is no translate button, so, I guess I gotta copy text to babelfish ever time I wanna read it?
11:18 AM flyback: actually you could dremel it off then heat press the new one
11:18 AM polprog: rue_mohr: new twitter ui?
11:18 AM flyback: but wrap the shaft and core in paper and zip tie
11:18 AM flyback: cause as you cut the bearing
11:19 AM flyback: it's going to get magenetically stuck to the shaft
11:19 AM flyback: all that dust
11:19 AM polprog: hmm
11:19 AM flyback: and don't cut the shaft
11:19 AM polprog: ill leave them alone for now
11:19 AM flyback: that's if this is a press on bearing
11:19 AM flyback: if it's just a clip then you just remove th clip
11:19 AM polprog: lemme look
11:19 AM polprog: i think this one has a clip
11:20 AM flyback: nice
11:35 AM flyback: nice repair job I doubt I could handle that cause my hands shake too much
11:35 AM flyback: polprog owns your "canuck"
11:35 AM * flyback tazers rue_mohr
11:35 AM polprog: what canuck :p
11:55 AM weyland|yutani: good idea tazering rue_mohr, he will invent something so you will attract massive lightning bolts everytime bad weather conditions are near you flyback
11:55 AM weyland|yutani: ;P
12:01 PM flyback: BMCC
12:23 PM katsumi: fck i'm fckn frnkn now

04:36 PM polprog: filling some casts?
05:16 PM flyback: rue_shop1, BMCC

05:16 PM flyback: esp8266
05:23 PM rue_shop1: BMSMA?
06:42 PM logb0t_ is now known as logb0t
