03:34 AM rue_mohr: freaking shoulder, its all crazy compound motions
03:35 AM rue_mohr: if you move your arm from straight out to straight up, it rotates about 90
05:54 AM Tom_L: .
01:11 PM rue_mohr: %^%$^&
02:05 PM Tom_L: oh?
02:08 PM rue_mohr: half the day gone by
02:08 PM rue_mohr: I need to do things
02:09 PM Tom_L: be a HomeDepot guy... How doers get more done...
02:17 PM polprog: evening
02:19 PM Tom_L: afternoon
02:25 PM polprog: possibly a new reverse engineering project
02:25 PM polprog: https://polprog.net/rozne1/ircjunk/various/iso7816/kpfgt/
02:27 PM Tom_L: what is it?
02:28 PM polprog: it's a device where you insert a payphone card and it tells you how much credit is left on it
02:28 PM Tom_L: ahh
02:29 PM Tom_L: that might go right along with rue's card reader
02:29 PM polprog: oh, what is rue doing?
02:29 PM Tom_L: door access
02:29 PM polprog: ah
02:29 PM polprog: yeah its for chip cards
02:29 PM polprog: likely the small eprom ones
02:29 PM polprog: SLE4442
02:31 PM rue_mohr: huh
02:31 PM rue_mohr: so you can use that to work out the card format and add money to it
02:32 PM polprog: maybe
02:32 PM polprog: the cards were write only so they started all 1's and for each credit the phone took, it wrote a zero to each bit from the end
02:32 PM polprog: so you cannot write a 1 back technically
02:32 PM rue_mohr: uv exposure...
02:32 PM polprog: you may be able to glitch it, but thats useless anyway...
02:33 PM polprog: hmmmm
02:33 PM polprog: they use coins in the phones in germany anyway
02:33 PM polprog: i had a cool photo when i was there last time
02:34 PM rue_mohr: cellphones anyhow
02:34 PM polprog: yeah
02:34 PM rue_mohr: telco here doesn't do payphones anymore
02:35 PM Tom_L: i haven't seen a pay phone in ages
02:39 PM polprog: they decom'd all the ones here in early 2000s
02:48 PM Tom_L: i forgot the command to restart apache..
03:25 PM polprog: /etc/init.d/apache2 restart
03:25 PM polprog: if old
03:25 PM polprog: if new
03:25 PM polprog: sudo systemctl restart apache2
03:25 PM Tom_L: i figured it out
04:54 PM rue_mohr: <rue_shop3> - recycling
04:54 PM rue_mohr: <rue_shop3> - fix mirror
04:54 PM rue_mohr: <rue_shop3> - dissassemble injector
04:54 PM rue_mohr: ok, mirror
05:02 PM rue_mohr: or take apart the injector
05:03 PM rue_mohr: got most of the scrap metal dealt with
05:03 PM rue_mohr: I think I run about a trip a year
06:21 PM rue_shop3: ok, yard trimmer work done while its not raining
07:36 PM Tom_L: ok debian pretty well set up
07:44 PM rue_shop3: I dont have a pipe fitting for making a new nozzel from, but I did find a peice of brass bar
07:44 PM rue_shop3: so, doing this the hard way
08:01 PM rue_shop3: huh, I broke a 1/8 npt die
08:32 PM rue_shop3: found a good bearing to use...
08:59 PM rue_shop3: after the 50th adjustment, I think I got it, the spring seems to be about as light as I can get it and the ball reseats properly
08:59 PM rue_shop3: and seals not-so-bad
09:08 PM Tom_L: spring doesn't have to be super loose
09:08 PM Tom_L: pressure will open it anyway
09:08 PM Tom_L: the heat may relax the spring some anyway
09:27 PM rue_mohr: its only 200c

09:48 PM Tom_L: so the ball goes against the brass?
09:49 PM Tom_L: ok i see now
09:52 PM rue_mohr: nope, goes against the steel
09:52 PM rue_mohr: so its an out-only check valve
09:52 PM rue_mohr: in the process, it generates some backpressure
09:52 PM rue_mohr: I just hope its not too much to prevent me injecting
09:53 PM Tom_L: i doubt it
09:53 PM Tom_L: not that little spring
09:53 PM rue_mohr: :)
09:53 PM Tom_L: may be hard to clean out
09:53 PM rue_mohr: shoudln't need to
09:53 PM rue_mohr: oh, to drain it... hmmm

09:55 PM Tom_L: i need to back up this debian install
09:55 PM Tom_L: not tonight
09:55 PM Tom_L: but i did get it set the way i want i think
10:35 PM rue_mohr: so, I found a little gold nugget, its a lego pneumatic cylinder
10:35 PM rue_mohr: they use a completely rubber piston
10:35 PM rue_mohr: I have an idea how to try it
10:43 PM Tom_L: hockey pucks
10:43 PM Tom_L: :)
10:45 PM rue_mohr: they have a bit of ) ( to them
10:46 PM rue_mohr: I think I can mold them in silicone hardneded up with a bit of corn starch
