06:21 <Noxz> sooooo coooool.. just discovered magnetic scales for DROs.. sony has the "Magnescale" .. basically magnetic tape encoded with a frequency and a head that travels with the carriage/whichever and reads the signal.. you can soooo easily hack that up for super cheap.. like go to any thrift store and get a tape reader/recorder.. resolution of better than 0.5 microns

06:23 <Noxz> I wonder what resolution VHS or Beta tapes could do..

06:28 <Noxz> one hackaday somewhat using similar tek.. https://hackaday.com/2017/09/07/hackaday-prize-entry-mini-dro-for-a-lathe/

18:20 <Noxz> Finally found some 2 degree (180step/rev) steppers

18:20 <Noxz> not new, but yeah

18:21 <Noxz> actually, there are new ones available

18:32 <Noxz> nema34, too, so likely a decent holding torque, even if unipolar

18:37 <Noxz> and $15 on ebay, and dude has 3, free shipping. good find, finally

19:03 <Noxz> submitted an offer of $10ea for the 3, will see.. no harm in trying

19:03 <Noxz> looks like he has two others with a slightly different moutning style

19:04 <Noxz> but same 180step/rev
