05:39 PM rue_mohr: k
05:39 PM rue_mohr: so zhanx what is the fastest you can repeatedly push a button?
05:39 PM Tom_L: 10 khz
05:41 PM rue_mohr: hahah
05:42 PM Tom_L: leather belt on a motor shaft :)
06:03 PM Tom_dev: test
06:05 PM Tom_dev: test
06:05 PM Tom_dev: about time...
06:07 PM rue_mohr: heh
06:08 PM Tom_L: setting up another linux box
06:08 PM Tom_L: added a ssd to my main pc for it
06:10 PM rue_mohr: how many ssd you running?
06:10 PM rue_mohr: some meet evela
06:11 PM Tom_L: quite a few
06:11 PM Tom_L: main pc has 4
06:11 PM Tom_L: shop mill has 2
06:12 PM Tom_L: spare test pc has 2 or 3
06:12 PM Tom_L: all samsung evo
06:30 PM rue_mohr: any of the die?
06:34 PM Tom_dev: no
06:34 PM Tom_L: they are one of the better brands as far as reliability
06:38 PM rue_mohr: I tried two
06:38 PM rue_mohr: kingston and
06:38 PM rue_mohr: adata
06:39 PM Tom_L: i had one tiny off brand and it still works but i don't use it much
06:39 PM Tom_L: i have sata and the M2 format
06:50 PM zhanx: ?
07:48 PM knoppix is now known as Moonmoon
08:51 PM rue_shop1: hey
08:52 PM zhanx: blue pill on one side and 2 esp's on the other
08:52 PM zhanx: while the pi has build in wifi, i wanted a bit more
08:53 PM rue_shop1: ok
08:53 PM rue_shop1: the pi cant do everything?
08:54 PM rue_shop1: atheros processor...
08:54 PM rue_shop1: x86?
08:54 PM zhanx: but it there is room after the pi zero w and the battery, i was thinking of cartridge mounts for later options
08:54 PM rue_shop1: hah
08:54 PM rue_shop1: why does it have to be a supercomputer?
08:54 PM zhanx: it doesn't
08:54 PM rue_shop1: ...
08:55 PM zhanx: with dual esp's i can do a man in the middle attack also
08:56 PM rue_shop1: ... ok
08:56 PM zhanx: also i could play with funky things on the bot
08:56 PM zhanx: main control does this, back up does that etc
08:57 PM rue_shop1: I wonder if the wifi on those is really noisy
08:57 PM zhanx: run them on different channels
08:57 PM zhanx: on which?
08:57 PM rue_shop1: https://www.linux-mips.org/wiki/Atheros_SOC
08:57 PM rue_shop1: huh
08:57 PM rue_shop1: kinda hoped for a plain ole arm or soemthing
08:58 PM zhanx: SoC: Broadcom BCM2835
08:58 PM rue_shop1: :) I got a whole bunch of these wander guard things as well
08:59 PM rue_shop1: atheros chipset
08:59 PM rue_shop1: wifi ethernet serial
08:59 PM zhanx: k we are talking 2 different things
08:59 PM rue_shop1: yes
09:01 PM rue_shop1: 64M of ram
09:02 PM rue_shop1: so its running an OS
09:02 PM rue_shop1: mips I think
09:02 PM zhanx: antenna is a resonant cavity which is formed by etching away copper on each layer of the PCB structure.
09:02 PM zhanx: sneaky
09:03 PM rue_shop1: they have two connectors on this, one is also connected to a local ...shaped peice of metal
09:04 PM rue_shop1: suppose I dont need really large ethernet to serial bridges....
09:33 PM zhanx: ok gonna use a pin to trigger an interrupt and send serial like that
09:33 PM zhanx: that way i can have 3 devices hooked to the same serial
10:54 PM rue_mohr: bit banging serial
10:54 PM rue_mohr: ok
10:54 PM zhanx: or round robin it
10:54 PM rue_mohr: I have a bit-banged serial library, but its not interrupt driven
10:54 PM zhanx: I am thinking i want interrupt
10:55 PM rue_mohr: yea
10:55 PM rue_mohr: you dont want a processor that fast doddeling for that long
10:55 PM zhanx: i was thinking that
10:56 PM zhanx: case dremeling is done now
10:56 PM zhanx: well first pass on it
10:57 PM zhanx: blue pill fits fine, but I need a passive usb hub also
11:01 PM rue_mohr: have you done any programming with those stm32?
11:01 PM zhanx: yes
11:01 PM rue_mohr: I found my Hammer board last night
11:01 PM Tom_L: those have alot of setup to do don't they?
11:01 PM rue_mohr: meh
11:01 PM zhanx: Tom_L, they do
11:01 PM Tom_L: you got a hammer?
11:01 PM rue_mohr: its like avr was back in 2002ish
11:01 PM rue_mohr: I did
11:01 PM Tom_L: i could have gotten one of those free
11:02 PM Tom_L: i forget the guy's name now...
11:02 PM rue_mohr: I played a fool and agreed to develop a web radio appliance for someone
11:02 PM rue_mohr: by the time everything arrived the guy said he wasn't interested and I ended up out of pocket for it all
11:02 PM rue_mohr: tin can tools iirc
11:02 PM Tom_L: the guy that makes em was gonna send me one
11:02 PM Tom_L: yeah that's it but i forgot his name
11:03 PM rue_mohr: I had to upgrade the kernel to make the network module work, and couldn't cross compile it
11:03 PM Tom_L: compact little board
11:03 PM rue_mohr: yep
11:03 PM zhanx: i bought a dragon isp, then used tom's board forever
11:03 PM rue_mohr: its the arduino of today yesterday
11:03 PM Tom_L: been playin with QtPyVCP
11:03 PM rue_mohr: yea, toms programmer rocks
11:03 PM rue_mohr: qt, ickgh
11:04 PM Tom_L: it's actually kinda neat
11:04 PM rue_mohr: yes, but it wont work tommorow
11:04 PM Tom_L: they've got it tied into linuxcnc's controls
11:04 PM rue_mohr: cause, QT
11:04 PM Tom_L: better than the other graphic gui they have
11:04 PM Tom_L: for touch screens
11:04 PM rue_mohr: yea, I need to write one
11:08 PM Tom_L: you were talking about ssd earlier... i've pretty much gone all ssd now
11:08 PM rue_mohr: no failures in how many months?
11:08 PM Tom_L: haven't had any problems
11:08 PM Tom_L: quite a while
11:08 PM zhanx: Tom_L, is slowly talking me in to ssd
11:08 PM Tom_L: the samsung are pretty reliable
11:08 PM rue_mohr: I was bitten twice.
11:08 PM Tom_L: and they're on sale at bestbuy right now
11:09 PM * rue_mohr just folds his arms
11:09 PM Tom_L: evo 860 500 is 79
11:09 PM Tom_L: hardly worth getting anything smaller
11:10 PM Tom_L: the price break isn't there
11:11 PM Tom_L: the 250 is 59
11:13 PM Tom_L: rue_mohr, do you have any M2 MBs?
11:14 PM rue_mohr: m2?
11:14 PM Tom_L: i don't think they're that much faster than sata
11:14 PM Tom_L: you mount the ssd to the mb
11:14 PM rue_mohr: oh, no
11:14 PM rue_mohr: sata isn't a speed limit
11:15 PM Tom_L: i think M2 is basically pcie
11:15 PM rue_mohr: from what I'v read, yes
11:16 PM Tom_L: https://www.newegg.com/Product/Product.aspx?Item=9SIA12K6V09508&Description=samsung%20evo&cm_re=samsung_evo-_-20-147-677-_-Product
11:17 PM Tom_L: has a screw mount on the end
11:17 PM rue_mohr: I'v seen one of the motherboards
11:17 PM rue_mohr: we did a new machine at work
11:17 PM Tom_L: my test pc has one but my main one doesn't
11:17 PM rue_mohr: I like the idea of upgradeing my machine
11:18 PM rue_mohr: but it would be ~$1000 and all I'd get is 100Mhz and an extra core
11:18 PM rue_mohr: which would not speed anything up
11:18 PM Tom_L: my main one is an i5
11:18 PM Tom_L: and the clock is slower than the test pc
11:18 PM Tom_L: but it runs faster
11:18 PM Tom_L: iirc the test pc has a i7 in it
11:19 PM Tom_L: with a tb M2
11:19 PM rue_mohr: I have a tripple core 3.3Ghz athalon
11:19 PM rue_mohr: intel speeds dont mean diddly
11:19 PM Tom_L: i don't push any of em anyway
11:20 PM rue_mohr: more cores wont help as software dosn't use 'em
11:20 PM Tom_L: a catia assembly might a little
11:20 PM Tom_L: catia does
11:20 PM rue_mohr: and 100Mhz extra isn't anything to even notice
11:20 PM Tom_L: i got more from switching to ssd than anything
11:21 PM rue_mohr: yea
11:21 PM rue_mohr: main drive and video card
11:21 PM rue_mohr: those things make a difference
11:21 PM Tom_L: i don't have any fancy video cards
11:22 PM rue_mohr: I'd upgrade the video card, but I have no idea if the new cards will work with the version of pcie on my motherboard
11:22 PM rue_mohr: I dont know if I ever want to go near ssd again
11:22 PM Tom_L: i'd have to get a bigger psu
11:22 PM rue_mohr: I'v got a USED magnetic drive going for my os drive, which is scarry
11:22 PM Tom_L: i have one card but it was uber cheap just so i could do dual monitors
11:23 PM rue_mohr: I'v had a program taking up 100% of one cpu for 2 weeks now
11:23 PM rue_mohr: not even noticed
11:23 PM rue_mohr: Power_On_Hours 54582
11:24 PM rue_mohr: thats my OS drive
11:24 PM rue_mohr: the raid..
11:24 PM rue_mohr: Power_On_Hours 68880
11:25 PM Tom_L: i was over 300 days on my server until the power went out a month ago
11:25 PM rue_mohr: Start_Stop_Count 89
11:25 PM rue_mohr: 773 hours av between power cycles
11:25 PM zhanx: uptime is for business not home use
11:26 PM rue_mohr: I dont like losing browser tabs
11:26 PM rue_mohr: computers should be able to keep going
11:26 PM rue_mohr: I find this windows update crap halarious
11:27 PM Tom_L: i don't do em
11:27 PM Tom_L: haven't had any issues
11:27 PM Tom_L: this one is on all the time
11:28 PM rue_mohr: the idea that a reboot will require waiting for an update so that when the computer comes back it doesn't work anymore
11:28 PM Tom_L: i dunno what ver of debian is on the server
11:28 PM rue_mohr: Tom_L, your case is rare...
11:28 PM Tom_L: i've got wheezy on the mill and stretch on the test pc
11:29 PM Tom_L: and win 64 & 32 & stretech on the main pc
11:29 PM Tom_L: win7
11:30 PM Tom_L: the 2 laptops they use are running 10 and i literally hate it
11:31 PM rue_mohr: 2nd icon from the left at the bottom has search, you can run cmd from it, and then call up all the programs by name
11:31 PM rue_mohr: explorer -> edge, same logo, ahhahahahahahahahahahaah!
11:32 PM rue_mohr: iexplorer, whatever, but halarious
11:32 PM rue_mohr: ok, I need supper
11:32 PM Tom_L: time to sleep here
11:32 PM rue_mohr: dont want to eat
11:32 PM Tom_L: early day tomorrow
11:32 PM rue_mohr: hmm
