02:59 AM rue_shop1: yay I think the new converter works!
03:39 AM rue_shop2: hahah
03:39 AM rue_shop2: a 10 minute print job from the pcb work station now takes 7 seconds
03:42 AM rue_shop2: a 10 minute print job from the pcb work station now takes 7 seconds
03:49 AM rue_shop2: its SO cool
03:49 AM rue_shop2: wish I'd done that long ago
04:08 AM rue_mohr: 2am, good night
04:36 AM Tom_L: aww
12:07 PM aandrew: rue_mohr: that's the "print" on the scope that spits out the print data on serial?
12:13 PM rue_mohr: yes
12:14 PM rue_mohr: I'm using the parallel port now, much faster and it avoids the controller with faulty ram
12:17 PM aandrew: very nice. so you have something on the PC that understands HPJS or whatever the hell the printer protocol is called (thankfully long since scrubbed from my memory) and creates a png or something from it?
12:18 PM aandrew: that's a really nice solution to a couple of problems. I wonder if that's tindie-worthy. there have got to be lots of people with old scopes, not necessarily with bad controllers but who'd appreciate the faster-than-serial print
12:21 PM rue_mohr: you can have the scope send in postscript
12:21 PM rue_mohr: then just use a postscript translator
12:23 PM rue_mohr: #!/bin/bash
12:23 PM rue_mohr: file="${1}.eps"
12:23 PM rue_mohr: scopecapture /dev/ttyUSB0 $file
12:23 PM rue_mohr: inkscape -f "$file" -w2048 -h1536 -e "${1}.png" 2>/dev/null
12:23 PM rue_mohr: gimp "${1}.png" > /dev/null 2>/dev/null
12:23 PM rue_mohr: exit 0
12:23 PM rue_mohr: --
12:23 PM rue_mohr: dograb 555variation1
12:24 PM rue_mohr: I print from gimp, thats why it brings it up with that
12:24 PM rue_mohr: usually do a colour invert in gimp before the print
12:43 PM aandrew: aha, I didn't realize the scope did PS, which is actually exactly what it should use
01:03 PM rue_mohr: well its got a lot of options, I chose the one with the smallest file size (vector)
01:12 PM rue_mohr: https://www.youtube.com/watch?v=4e1pfg6ut8U hmm
01:34 PM aandrew: not gonna lie, I thought he was gonna turn that bandsaw into a vertical chop saw type thing when I saw it rotate
01:35 PM aandrew: nice use of a wheel bearing
01:39 PM aandrew: interesting using the innertubes as a friction surface
01:40 PM rue_mohr: yea
01:40 PM aandrew: I guess that allows you to not need so much tension on the blade
01:40 PM rue_mohr: I think a few of those things are giving me some direction on projects
01:40 PM aandrew: I'm kind of in love with his grinder/chop saw set up
01:41 PM aandrew: how did you find this video? excellent find, thanks for sharing here
01:41 PM rue_mohr: a video caught my eye
01:41 PM rue_mohr: https://www.youtube.com/watch?v=xYkUsN9Ug_M
01:42 PM rue_mohr: in this one he has the slider beraing setup for the rectangular rod
01:42 PM rue_mohr: or someone else, I been blindly clicking
04:10 PM aandrew: https://www.youtube.com/watch?v=a6a5HTsYCSY looks impressive, I wonder how he so rapidly finds the screw hole centers though when he's mounting the chuck
07:01 PM rue_: aandrew, what I dont get in that video (seen before) is how he didn't wreck the sliders with all the weld splatter
07:02 PM rue_ is now known as rue_mohr
07:06 PM aandrew: That's a good question. I wonder how true it all is, it seems a lot of eyeballing went on but it also seems to work well enough to get probably 80% of the kinds of work most people want done.
07:07 PM aandrew: I've always appreciated that kind of enginuity.
07:07 PM aandrew: speaking of... how's the bathroom reno
07:10 PM polprog: thats a nice battery tester rue_mohr
07:10 PM polprog: :)
07:13 PM rue_mohr: aandrew, its on track the floor is ready for a new toilet, the might happen mon or ties
07:13 PM rue_mohr: tues
