01:46 AM rue_shop2: ok so
01:57 AM rue_shop2: from a base install of debian, with gui
01:57 AM rue_shop2: I have a command line calculator that had to be installed
01:57 AM rue_shop2: a hex dumper
01:57 AM rue_shop2: had to install acroread, which is non-trivial
01:57 AM rue_shop2: and recompile all the little utilities, cause of course this is a 64bit os now
01:57 AM rue_shop2: its perky tho
01:57 AM rue_shop2: I have to watch out for the mozilla, firefox, and chromuim caches, wow
01:57 AM rue_shop2: I still have to set up the printer
02:07 AM rue_shop2: oh I get to install all the arduino extensions again too dont I?
02:07 AM rue_shop2: hmmm
02:10 AM rue_shop2: arduino is nice for abstracting the compilation of code for all these fad microcontrollers
02:10 AM rue_shop2: stm32 esp8266 esp32 that I'v used so far...
12:21 PM polprog: rue_shop2: oo
12:22 PM rue_mohr: ?
12:22 PM polprog: that sram thing
12:22 PM rue_mohr: yea, I think 1M is as big as it gets
12:22 PM rue_mohr: is it fast enough for vga?
12:22 PM polprog: probably
12:58 PM rue_mohr: I'd like to play with refresh rate bending on non-analog video
12:58 PM polprog: hmmm, sounds like an fpga project
12:58 PM rue_mohr: if there is a pixel clock, why not bend it?
12:58 PM polprog: like, drawing the colorbars in 800x600 is pne of the first fpga projects
12:58 PM polprog: There was a PC demo that did that and i remember it did not work at all on LCD screens
12:58 PM rue_mohr: everyone seems to be doing vga stuff now
01:59 PM aandrew: heh
01:59 PM aandrew: I was just in a meeting with people named Uros, Ivan, Oleg and Rudy. I was the odd man out, the only one without a 4 character name
01:59 PM aandrew: Oleg says no problem, just call yourself Andy
02:00 PM aandrew: man's a damn genius. Now I too am part of the "name fits into a dword" club
02:03 PM polprog: its all fun and games until some little endian person comes and calls you ydna
02:04 PM polprog: i could fit my name into 4 chars too
02:04 PM polprog: chris - kris
02:20 PM rue_mohr: aandrew, hahah I was gonna say fits in 32 bits...
02:20 PM rue_mohr: haha, I have room for a \0
02:35 PM polprog: your irc nick fits in a qword
02:35 PM polprog: mine too, with a \0
04:19 PM rue_shop2: :]
04:19 PM Tom_L: off today ehh?
04:21 PM rue_mohr: so I'v been looking over connectomes of the brain
04:21 PM rue_mohr: Tom_L, yes, holiday today
04:21 PM rue_mohr: and the trunks are interseting
04:21 PM rue_mohr: most of them link the left and right sides
04:22 PM rue_mohr: I'm not sure if most of the ones I'm looking at are male or female data sets tho
04:22 PM rue_mohr: but the two hemipheres are kinda parallel linked
04:22 PM rue_mohr: almost all the other channels are minor in comparison
04:23 PM rue_mohr: polprog, changed the datasheet search alternating line background to ddd for some more contrast

06:00 PM Tom_L: what is it?
06:03 PM rue_mohr: the brackets are for moving the spindle regulator to the side of the cnc
06:03 PM rue_mohr: the other thing is a hybrid car battery
06:05 PM rue_mohr: did I show you the motor junction box?
06:05 PM rue_mohr: turns out there is an issue I didn't notice
06:05 PM rue_mohr: it hits that chip guard, I'll need something slimmer
06:06 PM rue_mohr: I need to work out where to put the plumbing bits
06:22 PM Tom_L: saw the junction box
07:04 PM aandrew: rue_mohr: second pic's a battery?
07:04 PM aandrew: ah yes
07:04 PM aandrew: just read, andrew
08:02 PM rue_shop2: so
08:03 PM rue_shop2: I just realized that with this new cnc, I can just mill the new engine pan for the 12' mecha
08:03 PM rue_shop2: I dont have to try to cast it
08:03 PM rue_shop2: I think
08:03 PM rue_shop2: Tom_L, feel like doodling with a cnc job?
08:03 PM rue_shop2: :)
08:05 PM rue_shop2: aandrew, guesses on the capacity?
08:05 PM rue_shop2: my guess is...
08:05 PM aandrew: capacity of the battery?
08:05 PM rue_shop2: yea
08:05 PM rue_shop2: 24Ah
08:05 PM rue_shop2: is my guess
08:06 PM aandrew: I suck at this, heh
08:06 PM aandrew: I mean if you assume the volume is all battery, split it in 3 and stack them and you get approximately the same volume as a 24ish Ah AGM battery
08:07 PM aandrew: I think your guess is probably pretty close but I'm not sure how this specific chemistry stacks up to AGM
08:24 PM rue_mohr: :]
08:51 PM Tom_L: what job?
08:59 PM Tom_L: rue_mohr, what project are you on now?
09:02 PM rue_mohr: the cnc project is an engine pan for a 2 stroke to run the compressor and stuff on the 12' mecha
09:02 PM rue_mohr: I was cleaning up
09:03 PM rue_mohr: I cleaned up the new mowerbot a bit and set it up outside
09:03 PM rue_mohr: cant have it in the shop anymore
09:12 PM Tom_L: not the first time that pan came up i believe
09:13 PM Tom_L: what sort of pan?
09:14 PM Tom_L: got a drawing?
09:14 PM rue_shop2: its a 2 stroke boat engine
09:14 PM rue_shop2: the pan is mostly important for the water cooling stuff
09:15 PM rue_shop2: I have a whole 3d model and the dxf I made it from
09:15 PM rue_shop2: I think its a job for ~1/2" plate
09:15 PM rue_shop2: (aluminum)
09:16 PM Tom_L: what's the 3d model in?
09:19 PM rue_shop3: stl, but its easier to rebuiild from the dxf
09:19 PM rue_shop3: stdn by I cant find the print
09:20 PM rue_shop3: oh I integrated the exhaust
09:20 PM rue_shop3: stand by
09:21 PM rue_shop3: unless its split up this wont work
09:24 PM rue_shop2: :/ its supposed to be near the top of the pile
09:24 PM rue_shop2: I'm rendering images
09:24 PM rue_shop2: you can tell me what ya think
09:24 PM rue_shop2: I'll put casting it back on the schedule
09:39 PM rue_shop3: http://ruemohr.org/%7Eircjunk/tempimage/mp1.png

09:39 PM rue_shop3: http://ruemohr.org/%7Eircjunk/tempimage/mp5.png
09:39 PM rue_shop3: I only remembered the flat base for some reason
09:41 PM rue_shop3: I'm going to do an experiment with a lost-pla casting and see what the quality comes out like
09:41 PM rue_shop3: I think the trick is to not pack the sand at all
09:41 PM rue_shop3: there was a video, maybe you showed it to me, of a guy who just used loose sand and it came out great
09:42 PM rue_shop3: I dont think it was even waterglass, just loose sand
09:46 PM Tom_L: yeah i think we discussed that one a while back
09:48 PM Tom_L: you didn't have those files at the time though
09:49 PM rue_shop3: I just did up those images, I'd have taken pics, but I cant find the prints
09:49 PM rue_shop3: everything is clogging up and I'm getting nothing done
