01:28 AM polprog: hmm
01:28 AM polprog: a lightbulb?
01:29 AM polprog: im going back to sleep :/
01:29 AM polprog: maybe you will hint me as to the sine amp :v
01:29 AM polprog: s/amp/osc/
01:30 AM polprog: wait, i think i see the two rc rcuitcs
01:30 AM polprog: c i r c u i t s *
01:34 AM polprog: going back to that japanese circuit is like a peak detector with automatic discharge
01:34 AM polprog: i think
04:18 AM rue_mohr: hmm
04:19 AM rue_mohr: why am I awake
07:21 AM polprog: that pesky sun probably got into your bedroom again
07:21 AM polprog: it's very high energy radiation, it surely can't be healthy :^)
08:37 AM rue_mohr: not yet
08:38 AM rue_mohr: not for about another half hour
08:38 AM rue_mohr: the MCP4728 has a really messed up i2c protocol
09:39 AM aandrew: I need to get back on my 3d printering
09:39 AM aandrew: I think I have to tune the retraction. short runs are hit and miss, but long runs are nice
05:14 PM polprog: what do you need the dac for?
05:15 PM polprog: also, it looks like a nice IC
05:21 PM polprog: nice, dp->vga converter is on the way, Ill hook up the second screen to the lab pc
05:22 PM polprog: we worked out the pairs for the ee labs, a friend will be coming over to me to do the labs
05:23 PM polprog: its nice to do electronics with another person, ive done nearly everything by myself so far
05:23 PM polprog: even if its something simple like hooking up a bjt or an opamp
06:00 PM aandrew: holy shitballs... ever have one of those days where just everything and everyone wants part of you at the same time?
06:00 PM aandrew: I'm about ready to declare a state of "fuck all this" and go live in a tree or something
06:02 PM Tom_L: lightening will strike it
06:04 PM Tom_L: and yes i have one of those about every other day\
06:05 PM aandrew: it comes in fits and spurts with me, but it's been crazy today
07:27 PM rue_mohr: polprog, for the power supply, reference gen
07:28 PM rue_mohr: aandrew, ouch :/
07:28 PM rue_mohr: ok, rock fitting, bbl
07:32 PM Tom_L: hardhat area
08:00 PM rue_mohr: wow, ordered 3mm mercury tilt switches from china and they actually arrived
08:00 PM rue_mohr: not sure what scares me more
08:01 PM rue_mohr: I'm falling asleep
08:01 PM Tom_L: surprised you can still buy those
09:03 PM rue_mohr: that was part of me trying
09:07 PM rue_mohr: ok, completely fit for mortar tommorow
09:07 PM rue_mohr: if I can
09:07 PM rue_mohr: falling asleep
09:07 PM rue_mohr: need to start supper
09:09 PM rue_mohr: that was about 25 rocks
09:09 PM rue_mohr: probably went thru 75 to find them
09:09 PM rue_mohr: which isn't too bad
09:10 PM Tom_L: where are the excess gonna end up?
09:10 PM rue_mohr: heh
09:10 PM rue_mohr: in a hole I suppose
09:10 PM rue_mohr: when I decided to bulk cut pieces, I knew they wouldn't all get a home
09:13 PM rue_mohr: they are almost done
09:13 PM rue_mohr: one is within about an inch, and the other about 3 inches
09:13 PM rue_mohr: I wonder if I'll finish this year
09:13 PM Tom_L: you'd better
09:14 PM rue_mohr: I dont have toppers for them
09:14 PM rue_mohr: I realized I'd like to put planters on top and do big ferns
09:15 PM Tom_L: to hide the rocks!?
09:15 PM rue_mohr: heh
09:15 PM rue_mohr: I think it would work
09:16 PM Tom_L: cement cap on top?
09:16 PM rue_mohr: I have to be abel to get it off
09:16 PM rue_mohr: the junction box is under it
09:16 PM Tom_L: pyramid shape only flatter
09:21 PM rue_mohr: yea
09:21 PM rue_mohr: thats the current idea
09:21 PM rue_mohr: but I like the planter thing
09:21 PM rue_mohr: stone
09:21 PM Tom_L: it will collect water and cause problems won't it?
09:21 PM Tom_L: especially when the water freezes in it
09:42 PM aandrew: I'm drinking moonshine and wasting time tonight
10:26 PM aandrew: https://pastebin.com/UJV8PaUt <-- anyone interested? Tom_L?
10:28 PM rue_mohr: Tom_L, data logger code from your direction used a DS1307
10:28 PM rue_mohr: aandrew, oh god
10:28 PM rue_mohr: where do I sign up
10:29 PM rue_mohr: I dont even know if I have the time
10:29 PM rue_mohr: thats insane
10:30 PM rue_mohr: Tom_L, its from dean
10:31 PM rue_mohr: hmm I just want to use the ram tho
10:35 PM aandrew: rue_mohr: what, the moonshine?
10:35 PM rue_mohr: no, got enough cleaner, the pdfs
10:35 PM aandrew: heh
10:35 PM aandrew: ok let me upload it
10:40 PM Tom_L: i think it may have
10:41 PM Tom_L: dean who?
10:42 PM rue_mohr: camera
10:42 PM Tom_L: data logger code?
10:42 PM rue_mohr: yea
10:42 PM Tom_L: no that was rif
10:42 PM Tom_L: iirc
10:42 PM rue_mohr: this code is signed dean
10:42 PM Tom_L: hmm
10:42 PM Tom_L: i dunno
10:43 PM rue_mohr: the DS1307 is signed dean
10:43 PM Tom_L: maybe he did one too
10:43 PM rue_mohr: maybe rif used it
10:43 PM Tom_L: i did a 1307
10:43 PM rue_mohr: I have a 1307, but I'm using it for NV ram
10:43 PM rue_mohr: ... its cheaper than NV ram
10:44 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/RTC3.jpg
10:44 PM rue_mohr: oh wait a sec
10:44 PM rue_mohr: files/programming/src/LUFA-111009/Projects/TempDataLogger/
10:45 PM aandrew: man I gotta give y'all shells so you can upload bigger images :-)
10:45 PM rue_mohr: hah
10:46 PM rue_mohr: but I'm supposed to get the MCP4728 working first
10:46 PM rue_mohr: and they made a horrid mess of the protocol
10:47 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/avr/Dallas%20RTC%20Code/
10:49 PM rue_mohr: huh, totally different
10:49 PM rue_mohr: might be more usable
10:51 PM Tom_L: i've no idea what or where most of my avr code is anymore
10:51 PM rue_mohr: hmm
10:52 PM rue_mohr: the code I grabbed to do i2c doesn't use the i2c
10:52 PM Tom_L: that one does
10:52 PM rue_mohr: yup, I want to find one with flurrys library
10:52 PM rue_mohr: but less hastle with the software
10:53 PM aandrew: rue_mohr: http://mixdown.ca/dump/machinistbooks.tgz it's about 2.5G
10:53 PM rue_mohr: thank gosh for fiber
10:54 PM rue_mohr: 2M/s that'll do
10:54 PM rue_mohr: good network test
10:54 PM aandrew: that's what I uploaded at
10:54 PM rue_mohr: heh 20m
10:55 PM rue_mohr: like dialup again!
10:55 PM aandrew: heh
10:55 PM aandrew: I've got 555GB of books I need to put somewhere downloadable eventually
10:55 PM rue_mohr: nice to not have to worry about falling asleep on a download and using up all yer minutes
10:55 PM rue_mohr: how much space on google drive?
10:56 PM aandrew: not sure, but I'm not gonna do that
10:56 PM rue_mohr: they dont care if you have a few accounts...
10:56 PM aandrew: I've gotta just put the share up
10:56 PM aandrew: I can share it via syncthing easily
10:57 PM aandrew: and I can probably get it up as an rsync share too if that's better
10:57 PM aandrew: I'm a huge fan of the syncthing though
10:58 PM rue_mohr: can wget resume a partial download?
10:58 PM rue_mohr: ist been so long since I ended up with one, I dont remember
10:58 PM rue_mohr: but I remember that being the whole thing about ftp vs http
10:59 PM aandrew: yep it can
11:04 PM rue_mohr: Filesystem 1K-blocks Used Available Use% Mounted on

11:05 PM aandrew: I need to get this SAN up
11:06 PM rue_mohr: :)
11:06 PM rue_mohr: t should be uppercase?
11:06 PM aandrew: 6 drive RAID6 is full, I bought a bigass 4U, 24-3.5"-bay NAS for $50
11:06 PM aandrew: er not NAS, SAN
11:06 PM aandrew: or is it NAS? I cant' remmeber
11:07 PM aandrew: all it is is dual power, dual SAS connector, and 24 bays, that's it
11:07 PM rue_mohr: you want the sata to sas adapters I got from an array?
11:07 PM aandrew: thankfully this thing takes 24 SATA drives, not SAS drives
11:08 PM rue_mohr: ok
11:08 PM rue_mohr: can't get into coding
11:08 PM rue_mohr: arg
11:08 PM aandrew: stupid $50 chassis needed a $50 cable and a $50 SAS card
11:09 PM rue_mohr: darn the encosure and stuff got chucked
11:09 PM rue_mohr: long ago
11:09 PM aandrew: that's unfortunate
11:09 PM rue_mohr: did you see the pile of drives?
11:09 PM aandrew: I think so
11:09 PM aandrew: my pile was miniscule in comparison. only 11 dead drives
11:09 PM rue_mohr: still stripping them
11:09 PM aandrew: my son's super happy though
11:10 PM rue_mohr: these were outgraded
11:10 PM rue_mohr: they got some other type of array
11:10 PM rue_mohr: these drives are small tho, like 300G
11:10 PM rue_mohr: high speed
11:10 PM aandrew: interesting. I have like 8 or 10 more but thye're working (for now)
11:11 PM aandrew: ah, real RAID drives. mine are just off the shelf, mostly 5400rpm
11:11 PM rue_mohr: I'd probably be wise to add a hot spare to my array now
11:12 PM rue_mohr: *blink*
11:12 PM aandrew: that's why I went to RAID6 - dual parity stripes
11:12 PM rue_mohr: what...?
11:12 PM rue_mohr: zippo:/morfiles/programming/c/avr/Atmega8/MCP4728test1# cat /proc/mdstat
11:12 PM rue_mohr: Personalities : [raid1]
11:12 PM rue_mohr: md127 : inactive sdd1[0](S) sde1[1](S)

11:12 PM rue_mohr:
11:12 PM rue_mohr: md0 : active raid1 sdc2[0] sdb2[1]
11:12 PM aandrew: I have two cold spares sitting on the shelf
11:12 PM rue_mohr: 955777982 blocks super 1.2 [2/2] [UU]
11:12 PM rue_mohr:
11:12 PM rue_mohr: unused devices: <none>
11:12 PM rue_mohr: what is md127....
11:13 PM aandrew: two spares from the look of it
11:13 PM rue_mohr: but....
11:13 PM rue_mohr: I dont ahve 5 drives in here...
11:14 PM aandrew: hm, were they removed at some point (usb disks or other) ?
11:14 PM rue_mohr: oooh
11:14 PM rue_mohr: I bet it was when I was trying to verify the phone system drives
11:15 PM rue_mohr: haha
11:15 PM rue_mohr: wow, that tgz is hell to unpack!
11:15 PM rue_mohr: this isn't a slow machine
11:16 PM rue_mohr: oh, those are huge files
11:16 PM rue_mohr: ok
11:17 PM aandrew: ok, I just ate a block of cheese too, not going to shit for a month
11:17 PM aandrew: it was good though, "smokin' goat" smoked cheese
11:22 PM aandrew: https://www.youtube.com/watch?v=j6_1nM4D7p4 this is such a bad song but I'm gonna be fucking humming it all day tomorrow
11:25 PM aandrew: needs to end about 2/3 into it though, goes too far off the rails but the melody is nice, as is the harmony
11:53 PM rue_mohr: and the answer is 500Mhz AMD with 1G ram and 4G flash drive
