10:15 AM aandrew: Wtf, my stupid rf splitter tweet has like 200 likes and a shitload of comments. That was completely unexpected
01:20 PM polprog: Morning rue
01:20 PM rue_mohr: hi
01:20 PM rue_mohr: true on slilinx
01:20 PM rue_mohr: xilinx
01:24 PM rue_mohr: Tom_L, can you find out if your paypal still works and I can get you the money sent today
01:25 PM Tom_L: lunch
01:25 PM Tom_L: i'm sure it does
01:26 PM rue_mohr: ok
01:27 PM Tom_L: then yardwork
01:27 PM rue_mohr: ooh
01:27 PM rue_mohr: 11:00
01:27 PM rue_mohr: lunch of breakfast... arg
01:28 PM rue_mohr: I have to go shopping too
01:28 PM rue_mohr: arg
01:30 PM polprog: Soo tired
01:30 PM polprog: But the photos are in
01:30 PM polprog: I taught my girlfriend how to take film photos
01:30 PM rue_mohr: polprog, scroll a quick look over the instruction set!
01:30 PM polprog: where is it?
01:30 PM rue_mohr: https://github.com/ruenahcmohr/OneBit
01:31 PM rue_mohr: just scroll the readme
01:31 PM rue_mohr: on the page
01:31 PM rue_mohr: there is a summary and then detailed descriptions
01:31 PM rue_mohr: NC = no connect
01:33 PM rue_mohr: I have a direction for an ALU :)
01:33 PM rue_mohr: thankfully, its only a 1 bit machine
01:33 PM polprog: Its interesting!
01:33 PM rue_mohr: I skipped insane stuff thats possible
01:33 PM polprog: Maybe you can learn the ancient powers of yacc to write an assember for it
01:33 PM rue_mohr: dude, thats main.c
01:33 PM polprog: Oh
01:33 PM rue_mohr: :)
01:34 PM polprog: Im on my phone
01:34 PM rue_mohr: I looked at, but didn't use lexx/yacc
01:34 PM polprog: But my laptop got a new external monitor, its yuge
01:34 PM rue_mohr: I thought about it
01:34 PM polprog: Ill take a look at home
01:34 PM polprog: I like the project :)
01:34 PM rue_mohr: I think it has a lot more value because there is an assembler for it
01:35 PM polprog: Yes
01:35 PM polprog: So its your rom cpu?
01:35 PM rue_mohr: not mine per say
01:35 PM rue_mohr: its a slight mod of that one I found
01:35 PM rue_mohr: https://laughtonelectronics.com/Arcana/One-bit%20computer/One-bit%20computer.html
01:35 PM rue_mohr: a lot of people have sighted it
01:36 PM rue_mohr: cited? ...
01:36 PM polprog: Cited
01:36 PM polprog: inreresting
01:37 PM rue_mohr: I tried to make as few mods as I could, the idea being to build an instruction set and assembler for it
01:37 PM rue_mohr: now its working and I just want to go crazy (and keep the chip count down)
01:37 PM rue_mohr: it runs up to 8MHz eh?
01:37 PM polprog: Wow
01:37 PM polprog: Thats quite abstract for me
01:37 PM rue_mohr: I think the limit is that rom chip
01:38 PM polprog: Maybe you can use a fast parallel flash?
01:38 PM rue_mohr: yea, or SDRAM
01:38 PM rue_mohr: }:]
01:39 PM polprog: Ooh yes
01:39 PM rue_mohr: 133MHz, if it could be done
01:39 PM polprog: It could be implemented on fpga
01:39 PM rue_mohr: yes, or a SMALL fpga
01:39 PM rue_mohr: 9572 might even work just fine
01:39 PM polprog: Its small enough a couple-ten units could be on a single fpga
01:39 PM polprog: Fault tolerant conputing
01:40 PM rue_mohr: :) multicore
01:40 PM polprog: haha
01:40 PM rue_mohr: I was also pondering having an FPGA proxy to a serial flash rom
01:40 PM polprog: yeah, i could write that as a generic rom replacement pcb
01:41 PM polprog: A *small* fpga and a spiflash
01:41 PM rue_mohr: the fpga could also have the rest of the machine hardware
01:41 PM rue_mohr: with a re-arrangement, it can have a lot more IO
01:41 PM rue_mohr: so, I have changes to play with :)
01:42 PM rue_mohr: I'll write assembler for each
01:42 PM polprog: I have tons of work for the eng thesis
01:42 PM polprog: Gotta learn vhdl and DSP
01:42 PM rue_mohr: heh dsp
01:43 PM rue_mohr: heh, get a 1 bit doing digital filtering, heheh
01:43 PM polprog: Yeah, need to push a value thru a function *fast*
01:43 PM rue_mohr: oh, not DSP processors per say, just the methods of dsp
01:44 PM rue_mohr: iirc its usually more important to do it in a fixed amount of time than to do it *fast*
01:45 PM polprog: Yeah, it neds to be a fixed short amount of time
01:45 PM rue_mohr: the fixed amount of time preferably being small
01:45 PM rue_mohr: is there a particular processor their targeting for the course?
01:46 PM rue_mohr: virtual 8051?
01:46 PM rue_mohr: heh
01:47 PM rue_mohr: a RISC core of some kind?
01:47 PM polprog: Not a course
01:47 PM polprog: Its an fpga, no softcore
01:47 PM polprog: Its a job
01:47 PM polprog: I have a project at a job as my eng thesis :-)
01:48 PM rue_mohr: oh cool
01:48 PM polprog: Tho i wish i had time to hammer the virtual 8051 into working
01:48 PM rue_mohr: ? it didn't work?
01:48 PM polprog: I have no idea why it always takes the jumps
01:48 PM rue_mohr: ooh
01:48 PM polprog: Yes it always takes conditional jumps!
01:48 PM rue_mohr: "timing problem"
01:48 PM rue_mohr: :)
01:48 PM polprog: Yosys is strange probably
01:49 PM polprog: I dont remember if i published it on git
01:49 PM polprog: Maybe i should
01:49 PM rue_mohr: I think there have been a LOT of changes to yosys on an ongoing bases
01:49 PM rue_mohr: basis
01:49 PM polprog: I will if you want to play with it! Its easy, i have a makefile that takes an 8051 rom file and spits it out...
01:49 PM polprog: Spits a bitstream out*
01:49 PM rue_mohr: oh
01:50 PM rue_mohr: you dont load the software and the 8051 seperatly?
01:50 PM polprog: Maybe if i come back to it now yosys would fix itself...
01:50 PM polprog: Noo, its a LUT in fpga. There is a script which converts an ihex into a verilog lut file
01:50 PM polprog: That I wrote
01:50 PM rue_mohr: what-his-name on twitter is always posting updates
01:50 PM polprog: My memory is foggy, i would have to look into the code
01:50 PM rue_mohr: oh
01:51 PM rue_mohr: shower, food, send money to tom, buy milk, ....
01:51 PM polprog: did you see the negatives i bought?
01:51 PM rue_mohr: I need to doc this 1 bit all up before I mod the hell out of it
01:51 PM polprog: They should come tomorrow, i cant wait to play with them
01:52 PM rue_mohr: I didn't quite get what your up do there
01:52 PM rue_mohr: to
01:53 PM polprog: I bought cheap film stock which at the same time is specialized stock
01:53 PM polprog: Aviphot 200 is AGFA stock for aerial photography. Its sensitive to near IR and has supposedly excellent imaging details (MTF curve)
01:54 PM polprog: Kodak Traffic Surveillance is low grain fast filmstock, guessing on the name it was probably used for traffic cameras
01:54 PM polprog: I just want to see how they perform in regular photography
01:55 PM polprog: And at the same time color film stock is like 4x more expensive
01:56 PM polprog: They want $10 for most basic kodak stock here at the shop
01:56 PM polprog: Bbl
02:15 PM rue_mohr: huh
02:15 PM rue_mohr: we forgot how to make colour film
02:19 PM rue_mohr: foood....
02:25 PM rue_mohr: wow I had a crazy house reno dream
02:31 PM rue_mohr: does _MY_ paypal still work...
02:40 PM rue_mohr: hey it does
02:40 PM rue_mohr: sean is apparently burried and hasn't been responding :(
02:53 PM rue_mohr: hey I was even able to work out the split
02:53 PM rue_mohr: Tom_L, I was worried you'd dropped dead for a bit there
03:16 PM rue_mohr: the willow cuttings done (last week?) have sprouted roots and I really need to get them into some pots
03:22 PM rue_mohr: ok, charger is on the truck
03:23 PM rue_mohr: I need to install a small charger under the hood
03:23 PM rue_mohr: timer, push the battery up to 15V for an hour each day
03:24 PM rue_mohr: its sunny, plausably I can work on the boiler more
03:24 PM rue_mohr: need to work out a firebox
03:24 PM rue_mohr: I just lack a shape
03:57 PM Tom_L: thanks rue
03:57 PM Tom_L: one day you won't have to worry
04:03 PM rue_mohr: :/
04:04 PM rue_mohr: you kinda suddenly stopped saying anything, I was starting to reply on your 2am chime as a dead-man-switch for I'v-been-playing-way-too-late
04:12 PM Tom_L: not much to say
04:59 PM rue_mohr: arg, I'm exhausted, getting nothing done
05:00 PM rue_mohr: if I could just be awake everything else would fall in place
05:00 PM rue_mohr: truck is probably charged
05:03 PM Tom_L: why doesn't it stay charged?
05:04 PM rue_shop3: 2 weeks sitting?
05:04 PM Tom_L: ok
05:04 PM Tom_L: so it's rebelling
05:04 PM rue_shop3: I TRY to drive it once a week
05:05 PM rue_shop3: I was looking at catalytic wood stoves
05:05 PM rue_shop3: seems there are two tiers
05:05 PM rue_shop3: stoves that have a secondary combustion air path
05:05 PM rue_shop3: and ones with an actual catalytic element
05:06 PM rue_shop3: which is interesting
05:06 PM rue_shop3: when I was like 14 I worked out that a secondary air /burn location made a wood oven run clean
05:07 PM Tom_L: i've got 3 but they're gas
05:07 PM rue_shop3: ;)
05:07 PM rue_shop3: I'm off shopping
05:07 PM rue_shop3: ... just milk aparently
05:07 PM Tom_L: 2 in the shop and 1 in the basement for emergency
05:08 PM Tom_L: started to do some yard work and was promptly told i couldn't
05:31 PM rue_mohr: by old man winter?
05:32 PM Tom_L: no
05:33 PM rue_mohr: I got the milk
05:33 PM Tom_L: was a nice day and i thought i'd get a start on it but she decided i'm supposed to wait for the boys
05:33 PM rue_mohr: and some cookies, cause I wouldn't want to waste fuel getting just one item
05:33 PM Tom_L: so another day just fucked away
05:33 PM rue_mohr: "opportunity is fleeting"
05:35 PM rue_mohr: I gotta be faster on the Bcomplex and ASA
05:35 PM rue_mohr: I could have taken the couch apart to day if I'd thought of it
05:35 PM rue_mohr: sun has ducked under the trees now
05:36 PM rue_mohr: but I need to go plant some willows
05:36 PM rue_mohr: before EOD
05:36 PM rue_mohr: then I can hide inside and work on a charger for the truck
06:00 PM aandrew: 600 likes now what the hell
06:09 PM rue_shop3: my stupid op-amp comment was at 111 this morning
06:22 PM Tom_L: kinda funny to see which ones take off and which ones don't
06:45 PM rue_mohr: the stupidest things do
07:08 PM Tom_L: that delay thing i got works like a champ but after i went thru the valve box and serviced all the valves i don't need it now
07:08 PM Tom_L: the differential springs were getting weak causing the valves to leak enough the selected one wouldn't engage
07:09 PM Tom_L: now they pop like a firecracker
07:58 PM WormFood: FINALLY got dual monitors working...I had to install a video card, because the on-board video card does not seem to drive 2 monitors under Linux.
08:03 PM rue_mohr: got that boiler pipe up to 80psi
08:03 PM rue_mohr: wanted to touch 100, but whatever
08:03 PM rue_mohr: Tom_L, :)
08:04 PM Tom_L: WormFood, then you should appreciat this http://tom-itx.no-ip.biz:81/~webpage/cnc/cad-station.jpg
08:04 PM rue_mohr: WormFood, setting up multiple monitors under linux is... interesting
08:04 PM rue_mohr: Tom_L, hahahaha
08:05 PM WormFood: I had a triple head setup in China, but now I don't have any GPUs
08:05 PM WormFood: I just got this ancient nvidia 610 video card, and it works, but not what I want. I want the on-board video to work.
08:06 PM Tom_L: rue_mohr, before i tear the setup down are you set for A12 for a while?
08:06 PM rue_mohr: I think were ok
08:06 PM rue_mohr: I need to make a ladel for making triggers!!!
08:07 PM rue_mohr: I keep losing my todo lists
08:07 PM Tom_L: i thought you did that one already
08:08 PM rue_mohr: the last one corroded out
08:09 PM rue_mohr: I'm ok with the boiler progress so far
08:09 PM rue_mohr: I need to set up an injection pump
08:09 PM rue_mohr: I have a small hydraulic pump that I think can do 200psi ok
08:10 PM Tom_L: old power steering pump maybe
08:11 PM rue_mohr: the one I have it sof boat trim tabs
08:11 PM rue_mohr: is for
08:12 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1230412.jpg
08:12 PM rue_mohr: the water gets injected into the end opposite to the red valve
08:16 PM rue_mohr: not doing the 'tank of water' design
08:16 PM Tom_L: mmm
08:16 PM rue_mohr: only the two T's area meant to be in the fire
08:17 PM rue_mohr: it was a sloppy test
08:17 PM rue_mohr: it'll need a dryer/seperator
08:18 PM Tom_L: i don't see where the pressure comes in
08:18 PM Tom_L: water vaporizes and causes expansion on a realtime basis
08:19 PM Tom_L: so in effect the injector could be considered the 'throttle body'
08:20 PM rue_shop3: maybe, the idea is that its just always making up for what it needs
08:21 PM rue_shop3: there isn't a huge tank of water ready to evaporate
08:21 PM rue_shop3: if its outputting 200psi of steam, you need the injection pump to overpower it
08:21 PM rue_shop3: its less power, but same pressure
08:22 PM rue_shop3: I worked out that an 80HP system would need like 1/2hp for the pump
08:23 PM Tom_L: the huge tank doesn't vaporize all at once though
08:23 PM Tom_L: similar to fuel injectors
08:26 PM Tom_L: more like diesel injectors since they're under pressure unlike throttle body or port injectors
08:36 PM rue_shop3: no, but if something ruptures it all goes off at once
08:37 PM rue_shop3: if the volume is kept down to just the pipes or less, there isn't the expansion potential
08:38 PM Tom_L: like being shot with a 2" barrel instead of a shotgun?
08:38 PM Tom_L: either are lethal
08:39 PM rue_shop3: big difference in energy release tho
08:41 PM rue_shop3: 1200x expansion?
08:46 PM Tom_L: what are those pumps called that use water to pump water?
08:46 PM Tom_L: like 2 tubes and some valves of some sort
08:46 PM rue_shop3: oh
08:46 PM rue_shop3: uh
08:46 PM rue_shop3: the roman ram thing
08:48 PM Tom_L: does it waste alot of water?
08:49 PM rue_shop3: yea
08:49 PM Tom_L: hmm
08:50 PM Tom_L: so the source water has to be higher than the pump but lower than the target
09:04 PM rue_mohr: ?
09:04 PM rue_mohr: yea
09:04 PM rue_mohr: it uses gravity and watter hammer to pump
09:04 PM Tom_L: yeah, just figuring where the energy comes from
09:04 PM rue_mohr: there is like a valve that slams shut at a larticular flow
09:04 PM Tom_L: nothing is free
09:05 PM rue_mohr: the water hammer re-directs the water to the higher grade
09:05 PM rue_mohr: and its behind a check valve
09:06 PM rue_mohr: looks like everyone starts getting home about 6:49
09:07 PM Tom_L: twitter?
09:07 PM rue_mohr: I'm ill!
09:07 PM rue_mohr: yes
09:07 PM rue_mohr: there is suddenly a flurry of likes n stuff
09:11 PM Tom_L: my highest fpga yt is 91
09:12 PM Tom_L: in contrast to some of the milling stuff at 1 - 5k
09:12 PM Tom_L: it's funny what attracts them
09:12 PM Tom_L: you put the fpga on your twitter and they'd probably go nuts
09:13 PM Tom_L: parting off softjaw blanks got 1.4k
09:13 PM Tom_L: just for cutting some silly blocks
09:13 PM rue_mohr: do you have any of the monitization set up for any of your youtube?
09:13 PM Tom_L: no
09:14 PM rue_mohr: hmm
09:14 PM Tom_L: linuxcnc on rpi 5.5k
09:14 PM rue_mohr: my co-worker pointed out he gets $50/mo combined from about 5 videos he posted
09:14 PM Tom_L: huh
09:14 PM rue_mohr: yea
09:15 PM rue_mohr: extra pocket change
09:15 PM Tom_L: they're probably done clicking by now
09:15 PM rue_mohr: who knows
09:15 PM Tom_L: that one showing you how i cut A12 got 163
09:15 PM rue_mohr: heh
09:16 PM rue_mohr: you just need the cat to walk into frame and your good for 10k
09:16 PM rue_mohr: hahah
09:16 PM Tom_L: no kidding
09:16 PM Tom_L: she watches dog yt all the time
09:16 PM Tom_L: sold a spindle motor with your A12 yt
09:16 PM Tom_L: rigid tapping went nuts too
09:17 PM Tom_L: i don't like it when they're staged
09:19 PM rue_mohr: sold a spindle motor?
09:19 PM Tom_L: I ordered the same spindle motor for my own mill and your videos are really hyping me up.
09:19 PM Tom_L: sucker
09:19 PM rue_mohr: hah
09:20 PM rue_mohr: that would be less confusing with quotes eh?
09:20 PM rue_mohr: I'v had thingiverse prod be twice about setting up for donations
09:20 PM Tom_L: probably
09:20 PM rue_mohr: not sure if I should
09:20 PM Tom_L: why not?
09:20 PM rue_mohr: guess I cant get money if I dont
09:20 PM Tom_L: doesn't cost anything
09:20 PM rue_mohr: I'm just a beleiver that everything has strings
09:21 PM Tom_L: if i did then i'd feel pressured
09:21 PM Tom_L: of course
09:21 PM rue_mohr: yea
09:21 PM Tom_L: they leach viewers off you
09:21 PM rue_mohr: but, suckers with too much money, right?
09:21 PM Tom_L: and dump ads on your site
09:21 PM rue_mohr: I think a soul sells for a lot too
09:22 PM Tom_L: some more than others
09:22 PM rue_mohr: I been pondering billionares latley
09:22 PM rue_mohr: its interetsing
09:22 PM rue_mohr: when you break down elon musk
09:23 PM rue_mohr: he's just really good at using other peoples money and selling to people that pay a LOT
09:24 PM rue_mohr: big companies pay crazy amounts of money for things that they often just throw away
09:24 PM rue_mohr: IP
09:25 PM rue_mohr: I'v come to the conclusion that people NEED things to spend money on
09:25 PM Tom_L: it's not what you have, it's how you market it
09:25 PM rue_mohr: like bitcoin, and NFTs
09:25 PM Tom_L: fidgets
09:26 PM Tom_L: stupid idea
09:26 PM Tom_L: made millions
09:26 PM Tom_L: those spinners
09:27 PM rue_shop3: yup I follow
09:27 PM Tom_L: had to be global because we both know
09:29 PM Tom_L: According to the Wall Street Journal, fidget spinners sales brought in revenue totaling $2.6 million last month, and one toy manufacturer told the paper that they are seeing 200 orders an hour for the catchy toys.May 4, 2017
09:49 PM rue_mohr: yea, I have no energy to do anything
09:49 PM rue_mohr: I'll try anyhow
09:50 PM rue_mohr: I have a schematic for a battery charger for the truck
09:50 PM rue_mohr: not smart, pulls the voltage up to 15V and cycles it there slowly
09:50 PM rue_mohr: idea is to put in on a timer, 1 hour every day
09:50 PM Tom_L: like a motorcycle cycler
09:51 PM rue_mohr: oh, I dont know
09:51 PM rue_mohr: its a thing?
09:51 PM Tom_L: for winter yes
09:51 PM rue_mohr: huh
09:51 PM Tom_L: they don't ride much in the winter
09:51 PM rue_mohr: yea
09:51 PM rue_mohr: ok, so
09:51 PM rue_mohr: ... so
09:51 PM rue_mohr: I need a transfomer
09:51 PM rue_mohr: 12V min.
09:51 PM rue_mohr: 12VAC
09:51 PM rue_mohr: high current
10:02 PM Tom_L: haha you need my charger thing...
10:03 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/12v_supply1.jpg
10:03 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/12v_supply3.jpg
10:03 PM Tom_L: keep forgetting i have that
10:04 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/12v_supply2.jpg
10:11 PM rue_mohr: wow, I'v seen those before,t heir nice
10:18 PM Tom_L: rv charger
10:18 PM Tom_L: was upgraded so i got it free
10:19 PM Tom_L: i've never done anything with it
10:20 PM rue_mohr: I'v seen a few, I dont recall where
10:28 PM rue_mohr: hahaha
10:29 PM rue_mohr: oops :)
10:29 PM Tom_L: cat tickle your foot?
10:29 PM rue_mohr: I think I posted something to someone on twitter that might cause a follower inrush
10:29 PM rue_mohr: 3..
10:29 PM rue_mohr: lets see what happens here
10:29 PM rue_mohr: 4...
10:31 PM rue_mohr: yup, I feel like I just want to go back to sleep
10:36 PM rue_mohr: 5...
10:40 PM rue_mohr: 6...
10:40 PM rue_mohr: I'm sure twitters rate limiting kicked in
10:44 PM rue_mohr: 7...
10:45 PM rue_mohr: 8...
10:46 PM Tom_L: hundred?
10:46 PM rue_mohr: no, just notifications since posting that
10:46 PM rue_mohr: not neccissarily followers or anything
10:46 PM Tom_L: why would their limits kick in on that?
10:46 PM Tom_L: i've not been on it...
10:46 PM rue_mohr: it seems if I look up what they are, twitter throttles harder, so I'm just gonna watch it for a bit
10:47 PM rue_mohr: they have an alg that tries to prevent posts from instantly balooning
10:47 PM rue_mohr: its a throttling kinda thing
10:47 PM rue_mohr: every so often they brake it and you see things go crazy
10:48 PM rue_mohr: break
10:48 PM rue_mohr: wtf rue
10:48 PM rue_mohr: 10...
10:49 PM rue_mohr: 11....
10:50 PM rue_mohr: see, twitter cant clamp down things people really go super crazy on
10:53 PM Tom_L: pet rock?
10:53 PM rue_mohr: yea wtf, if I'd done it, it never would have gone anywhere
10:53 PM rue_mohr: WHY did that take off
10:53 PM rue_mohr: it wasn't the idea, it had to be the implementation
10:54 PM Tom_L: the 1bit processor?
10:54 PM rue_mohr: no
10:54 PM rue_mohr: hardly anyone is interested in that
10:55 PM rue_mohr: oh I posted a model robot person info on my mecha
10:56 PM rue_mohr: 12...
10:56 PM rue_mohr: ok lets see what these 12 notifications are
10:56 PM Tom_L: i found it odd most of the yt with comments were foreign
10:57 PM rue_mohr: ferrite core comment
10:57 PM rue_mohr: mecha
11:11 PM rue_mohr: warning about steam boilers...
11:12 PM rue_mohr: like like like
11:12 PM rue_mohr: reply about nixies..
11:12 PM rue_mohr: like like like like, huh
11:12 PM rue_mohr: https://i.pinimg.com/originals/6d/7b/83/6d7b835d0a7219d9e352db2ff40af692.jpg
11:13 PM Tom_L: wtf
11:13 PM rue_mohr: I bet loggers weren't good about checking their boilers and not dialing up the reliefs
11:15 PM rue_mohr: good gig tho, dont have to pay for fuel
11:15 PM Tom_L: wood burners?
11:15 PM rue_mohr: why woldn't they?
11:15 PM Tom_L: yeah
11:15 PM Tom_L: maybe too green?
11:15 PM rue_mohr: good hot fire and it doens't care
11:16 PM rue_mohr: Rue sitting at computer tooo much!
11:17 PM rue_mohr: ok, I'm not sure what else to do
11:17 PM rue_mohr: maybe I could get some parts ready for that aluminum ladel
11:18 PM Tom_L: some of those old machinery pics & videos are interesting
11:18 PM rue_mohr: yup
11:18 PM rue_mohr: I seen a lot of pics of those donkey engies blown up
11:18 PM rue_mohr: I wonder if they had the recert requirement back then
11:19 PM rue_mohr: I expect they did, and the loggers never did it
11:19 PM Tom_L: seriously doubt it
11:19 PM rue_mohr: and dialed up the regulators
11:19 PM rue_mohr: I never seen a logger say "dont force that or it might break"
11:20 PM rue_mohr: but I have seen a front end loader at a sort yard with a crumpled front arm
11:21 PM rue_mohr: I wonder if those were copper tubes
11:23 PM rue_mohr: the pipe is good rated to 2700psi cold, all those fittings are 200psi min
11:23 PM Tom_L: probably not
11:23 PM rue_mohr: the relief is 140psi
11:23 PM rue_mohr: the pipe chart says failure at something like 13000 psi
11:23 PM Tom_L: the connections blew out not the pipe
11:24 PM rue_mohr: the fittings would come apart before any of that
11:24 PM rue_mohr: yea
11:25 PM rue_mohr: I was quite annoyed that the check valve I used wouldn't stay shut
11:25 PM rue_mohr: its just got a gravity flap tho
11:25 PM Tom_L: spring too weak?
11:25 PM rue_mohr: no spring, just gravity
11:25 PM rue_mohr: all brass tho, no rubber
11:25 PM Tom_L: it should have a spring
11:25 PM rue_mohr: probably,
11:26 PM rue_mohr: I was got up to 20psi, but I was running out of water
11:26 PM rue_mohr: 2447
11:27 PM rue_mohr: hardly ever seems to go down...
11:28 PM Tom_L: imagine the pile if all the abandon metal was recovered
11:29 PM rue_mohr: USUALLY when you find a boiler like that, all the tubes are gone
11:29 PM rue_mohr: because back in ??? there was a thing with copper and everyone looted everything
11:30 PM rue_mohr: there are a few engines on the mountian here, (gas) and they are all methodically taken apart with all the brass and copper bits missing
11:32 PM rue_shop3: I bet if I just sit in the shop instead, more will get done
11:32 PM Tom_L: to mine steel you'd think it would be cheaper to recover it
11:32 PM Tom_L: my eyes won't stay open any longer
11:34 PM rue_shop2: yea
11:35 PM rue_shop2: I'm just gonna sit and feel guilty for not getting anything done
11:35 PM Tom_L: while you do that, i'll go take a long nap
11:37 PM rue_shop2: I suppose I can sort things
11:40 PM rue_shop2: its so much warmer in there
11:40 PM rue_shop2: here
11:45 PM rue_shop2: I also need to keep working on reverse engineering myself
11:46 PM rue_shop2: I been collecting possibly way too much ldpe to make machineable wax from
