yoleaux24 Sep 2015 08:19Z <nmz787> chris_99: I just got the new mini laser etcher to cut via wine in ubuntu  and something like this : ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1     (I shouldn't have even messed with trying on Windows 8, no driver support, was a big waste of time... I shouldn't have even rebooted)05:12

kanzurehad to explain that the file was already offline, that no i didn't scan it (i neglected to mention that scanning isn't illegal), that even google has to comply with the dmca takedown process and what that is or why it exists, etc.08:16
Betawolfdid he give you the student?08:18

nmz787_wcpopell4: what is SE>KE?11:29
chris_99etched anything cool with the laser thingy nmz787_w?11:30
nmz787_wchris_99: not yet, screwed around for a while yesterday finding a USB flash drive or SD card that would take a lubuntu ISO and also boot successfully on my eeePC... which I want to use as a laser-print-server so I can put the etcher in a room by itself (or whichever room might become a lab room)11:34
chris_99ah cool, you mentioned you'd tried wine, does it not run natively on linux?11:35
nmz787_wjust etching even paper was a bit smelly, and I didn't want to leave it alone when I went to bed a few nights ago when I was first testing it... was afraid I would be RUDELY awakened by a smoke detector11:35
chris_99ah heh11:35
nmz787_wwell the device is supposed to be arduino nano based, and compatible with grbl... but I think that is a firmware... not sure if I can pump grbl-compatible g-code to it as-is... or if I need to reflash the firmware11:36
nmz787_wbut the wine was for the app the company provided, or linked to11:36
chris_99ah gotcha11:36
nmz787_wI had my eeePC setup with winxp, because there was some free audio-based oscilloscope that I was trying out, which was windows only... but then I got my oscilloscope (this was almost 2 years ago now I guess) and I haven't touched the eeepc since then11:37
nmz787_wso now it is dual-booting with lubuntu as the default11:37
chris_99what oscilloscope do you have?11:39
nmz787_wcpopell4: this? http://www.ksi.edu/seke/seke15.html11:40

yoleauxSHOP TIPS #192 Intro. to Gears & Gear Cutting on Bridgeport Mill tubalcain - YouTube12:53
justanotheruseryou also don't have plumbuses in your list12:54
chris_99could you cut gears with a milling machine instead?12:56
justanotheruserThat was my initial intention, but they aren't keen on the idea12:57
justanotheruser13:27 < archivist> justanotheruser, the shape has a rectangular root form12:57
justanotheruser13:27 < aventtini> there is by any chance im conected to the 5v sw and the signal is to fast for the drives ?12:57
justanotheruser13:27 < justanotheruser> so I cannot get the precision I need when is rectangle based?12:57
justanotheruser13:28 < archivist> look at the bottom of gear slots http://gears.archivist.info/gears/IMG_1214_hires.JPG12:57
justanotheruser13:28 < archivist> now show me a small enough endmill12:57
justanotheruser13:30 < justanotheruser> archivist: why can't I just make a spur12:57
justanotheruser13:31 < archivist> justanotheruser, you normally use a gear cutter and a rotary to make spurs12:57
justanotheruserso the answer seems to be yes you can but you better not need precision12:58
chris_99aha gotcha12:58

kanzure"After proposing the use of computed tomography*1 to read data recorded with a femtosecond pulse laser*2, fused silica glass was confirmed as an effective storage medium"14:38
kanzure14:33 <+xentrac> yeah, fused silica is very stable14:38
kanzure14:33 <+xentrac> it will presumably eventually crystallize14:38
kanzure14:34 <+xentrac> but I think the timescale for fused silica to crystallize is longer than the universe to date14:38
kanzurepdfparanoia should be updated to make certain statements about a collection of documents, such as the number of docs that have detected watermarks, the number of docs that have unknown watermarking status, etc.14:39
