05:05 AM Tom_itx is now known as Tom_L
10:15 AM rue_mohr: oh
10:15 AM rue_mohr: the roads are a slippery mess and there is a snow warning, I'm apparently staying in for the day
11:35 AM rue_mohr: the cats had me up a good % of the night
12:27 PM aandrew: what were they doing to keep you up
12:27 PM rue_mohr: at 12 one can DEMANDED food
12:28 PM rue_mohr: then around 2 or 4, the other can DEMANDED I open my bedroom door, even tho he apparently didn't come in and sleep
12:29 PM rue_mohr: they howl good when they feel motivated
12:30 PM aandrew: jeez, that'd be enough for me to send them outside for the night, or at least into your workshop :-)
01:09 PM rue_mohr: I'm working on that tri laser module again
01:09 PM rue_mohr: trying to get all 3 in a 12mm space
01:09 PM rue_mohr: so 0 6, and -6
01:10 PM rue_mohr: mm offset
01:10 PM rue_mohr: it would probably be smarter for my to find a linear side
01:10 PM rue_mohr: hmm I wonder now
01:11 PM rue_mohr: trying to make the multilaser module is a whole heap of sacrifices
01:11 PM rue_mohr: but with multiple lasers you can see the focal point outright
01:12 PM rue_mohr: my camera does have a long exposure setting tho
01:18 PM rue_mohr: hmm, needs to be too dark
04:23 PM rue_mohr: 2152, reference point
04:30 PM Tom_L: up a bit
04:36 PM rue_mohr: oh I dotn remember
04:36 PM rue_mohr: it seem to be changing so I was going to re-check in a while
04:37 PM rue_mohr: so I'm making a little parallel line laser box for reverse engineering lenses
04:37 PM aandrew: rue_mohr: ah yes we talked about this ... last spring/summer?
04:37 PM rue_mohr: ... I'm still working on it....
04:38 PM rue_mohr: I had some new ideas
04:38 PM rue_mohr: trying to make it adjustable is a problem
04:39 PM rue_mohr: I'm doing it with 6mm beam distance
04:40 PM aandrew: https://ibb.co/yFc6J7Y that kind of thing right?
04:40 PM rue_mohr: the modules are 9mm dia, so thats fun
04:40 PM rue_mohr: yes
04:40 PM rue_mohr: but mine will be staighter...
04:40 PM rue_mohr: :)
04:40 PM aandrew: well those are adjustable but yes
04:40 PM rue_mohr: and I'm 6mm distance for smaller lenses
04:41 PM rue_mohr: that ones pretty clear how they can trim them
04:41 PM rue_mohr: I'm gonna use 3 grub screws
04:41 PM rue_mohr: tho, I am seriously thinking that just a single laser on a slide might be great
04:42 PM rue_mohr: bit harder to make out the focus point, but I'm sure it might not matter maybe
04:42 PM rue_mohr: totally sure
07:09 PM aandrew: woo that was a little scary
07:09 PM aandrew: [5215758.323542] XFS (dm-0): SB summary counter sanity check failed

07:10 PM aandrew: couldn't unmount, but did a proper shutdown/reboot. failed to boot completely (drop to maintenance mode), ran xfs_repair, completed without error, remounted fine, exited maintenance mode and continued as normal
07:10 PM rue_mohr: wow
07:10 PM aandrew: not sure if that was ECC RAM saving my ass, the XFS driver doing a good deed or what, but it's all good
07:24 PM rue_mohr: ok, 3d printed parts printed,
07:24 PM rue_mohr: assembly time
07:56 PM rue_shop3: wholy frustration!
07:56 PM rue_shop3: one of the guides is distorting the other
08:39 PM rue_mohr: and I scratched one of the diffusion lenses
08:45 PM rue_mohr: ok, ok
08:45 PM rue_mohr: maybe If I change path and do the sliding laser thing
08:45 PM rue_mohr: atleast then I can rule it out as being a solution
09:53 PM rue_mohr: intead of making a box, I wonder if I should just make magnet mounts and put them on a steel plate
