12:33 AM rue_mohr: I got 5 transistors to do a binary decode of a 4x4 matrix keybaord!
12:45 AM Tom_L: no
12:46 AM Tom_L: https://www.openfoam.com/
12:47 AM Tom_L: https://fluidityproject.github.io/
12:48 AM Tom_L: http://mantaflow.com/
01:16 AM zhanx: thanks Tom_L
01:26 AM Tom_L: if i have a router attached to a switch behind my main router can i use the wifi from it to get out to the interweb?
01:26 AM Tom_L: i know a router behind a router isn't the best idea
01:26 AM Tom_L: but i can't get wifi in the garage
01:28 AM zhanx: Tom_L, as smart as you are, i am puzzled
01:29 AM Tom_L: well i'm tired
01:29 AM Tom_L: just finished installing a garage door opener
01:29 AM Tom_L: had to redo all the wiring etc
01:44 AM rue_mohr: yea, if you have to do a router behind a router, make sure the subnets are different
01:44 AM rue_mohr: lots of routers get confuxed if they have 192.168.0.x on the inside and outside
01:45 AM rue_mohr: netmask 255.255.0.0 192.168.1.x and 192.168.2.x
01:47 AM zhanx: 255.255.255.0
01:50 AM rue_shop1: ohm, right
01:56 AM Tom_L: should i disable dhcp on the inside router?
01:56 AM rue_shop1: no
01:56 AM rue_shop1: the dhcp requests wont pass thru
01:56 AM Tom_L: ok i'm too tired to think. goin to sleep
03:58 AM rue_mohr: agreeed

04:00 AM rue_mohr: 5 transistors, and like 5 resistors, plug in a 4x4 matrix keybaord, get a 4 bit binary value out, with a key-is-down line
08:43 PM rue_mohr: ok, I'm freaking about getting a cover made
08:43 PM rue_mohr: I'm going to give up on the construction guy who I cant connect with
08:44 PM rue_mohr: just made a picklist for my design
08:44 PM rue_mohr: I wonder if I'll get the weather to build it
08:59 PM rue_shop3: hmm rain started, I hope I have a chance to get the mixer tommorow
09:52 PM Tom_L: ok router all set up
09:52 PM Tom_L: garage door monitor on the phone works
09:59 PM Tom_L: cover for what?
10:12 PM rue_shop3: rain
10:12 PM rue_shop3: need to move stuff around, need to change covered space
10:14 PM Tom_L: old opener i had gave out again. i'd repaired it half dozen times
10:15 PM Tom_L: i don't think it was big enough for the weight so i gave up and got one
10:15 PM Tom_L: gear case kept cracking under the load
10:16 PM rue_shop3: motorized then?
10:16 PM Tom_L: yeah
10:18 PM rue_shop3: you have a cnc machine
10:18 PM rue_shop3: can you find a block to make a new base for the gearbox from?
10:19 PM rue_shop3: hmm, the last arm initialized by the program is the only one that works
10:20 PM Tom_L: i probably could but it's hardly worth the time or effort
10:21 PM rue_shop3: how much is the entertainment your going to enguage in going to cost you while your not fixing it?
10:23 PM Tom_L: i would pay for that anyway because i'm not the only soul using it
10:23 PM Tom_L: and i can engage you for free
10:24 PM Tom_L: the door springs should be replaced
10:24 PM Tom_L: they've both broke at least once and i keep shortening them since the end is where they always seem to break
10:25 PM Tom_L: so it's probably more effort closing the door than opening it
10:25 PM rue_shop3: I was looking at the door pins on the S10
10:25 PM rue_shop3: I think they come out
10:25 PM rue_shop3: without breaking any welds
10:25 PM Tom_L: probably pressed in half of it
10:26 PM Tom_L: do they need to come out?
10:26 PM rue_shop3: looks like I have a 50% chance of the wear all being in bushings
10:26 PM rue_shop3: its hitting the pin when ya close it
10:26 PM rue_shop3: I cringe every time
10:26 PM Tom_L: haven't been keepin em lubed ehh?
10:26 PM rue_shop3: its a 91
10:26 PM Tom_L: mine was a 92
10:32 PM Tom_L: i kept the books for it
10:33 PM rue_shop3: :)
10:33 PM rue_shop1: I should get those books from you maybe one day
10:37 PM rue_shop3: write failed! /dev/ttyUSB1
10:37 PM rue_shop3: arm write: Bad file descriptor
10:45 PM rue_shop3: write failed! /dev/ttyUSB1 (165725768)
10:45 PM rue_shop3: the file descriptor should be 5
11:45 PM rue_mohr: https://www.instructables.com/id/CNC-Router-4/
11:45 PM rue_mohr: hmm
11:46 PM zhanx: wow even after calling misumi they still mis-shipped the package
11:48 PM rue_mohr: https://www.instructables.com/contest/metal2019/
11:48 PM rue_mohr: I wonder how my odds are
11:48 PM zhanx: bet you win it
11:49 PM rue_mohr: dunno, some of those entries are pretty good
11:51 PM zhanx: they are
11:51 PM zhanx: but yours is better, i have faith
11:59 PM rue_mohr: well
11:59 PM rue_mohr: today I made a new lid for the smelter
