07:09 PM ShopMoon: rue_mohr: is that a amp that's gain runs away and heats up to the temp of a SuperNova and destroyes the earth?

07:42 PM rue_mohr: ShopMoon, did you get the cb brian left you?
07:42 PM Tom_L: ali says you can custom order but gives you no avenue to do so
07:44 PM rue_shop3: maybe no sellers support it yet
07:44 PM Tom_L: it was the seller that said it
07:45 PM Tom_L: xl timing pulley, 2 flanges, 28T, 9.5mm wide, 14mm bore, 5mm keyway
07:46 PM Tom_L: for instance
07:53 PM rue_shop3: yea, you order something close and say whatever you want in the comments to seller beofre you pay it
07:53 PM Tom_L: you had good luck that way?
07:53 PM rue_shop3: dosnt' happen often but yes
07:53 PM Tom_L: i found one here just now that's close
07:54 PM rue_shop3: sometime they do a generic listing for things
07:54 PM rue_shop3: you specify the details in the comments when you buy it
07:54 PM rue_shop3: otherwise they send a default
07:55 PM Tom_itx: https://www.aliexpress.com/item/33005115233.html?spm=2114.12010612.8148356.27.60e34609e8ArP2
07:55 PM Tom_L: i'm not exactly sure how many teeth i need though
07:55 PM Tom_L: until i get a motor etc
07:55 PM Tom_L: won't know the space constraints
07:56 PM rue_shop3: well you ahve to know
07:56 PM Tom_L: main thing i don't know is what the center distance will be to size the belt
07:57 PM Tom_L: looks like they have pulleys and belts though
07:57 PM rue_shop3: yea too many combinations for the listing
07:57 PM rue_shop3: wow I can type on the model M
07:57 PM Tom_L: i can narrow that down
07:58 PM rue_shop3: having severe typing problems on keybaords latley
07:58 PM Tom_L: i know pretty much what i need
07:58 PM rue_shop3: 10mm belt?
07:58 PM Tom_L: yeah i'm using 9.5 wide right now
07:58 PM Tom_L: i'd like to go with 15 but don't think i have room
07:59 PM Tom_L: i think 10 would be ok
07:59 PM rue_shop3: I was looking for big stuff for the cnc
07:59 PM rue_shop3: but $$$
07:59 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/new_pulleys/timing_pulley3.jpg
08:00 PM Tom_L: that's what is on it right now
08:00 PM rue_shop3: maybe I should just have my machine cut its own rack
08:00 PM Tom_L: i'm going with a coarser pitch (XL instead of GT)
08:00 PM Tom_L: those multi V belts are attractive but i can't use them
08:01 PM Tom_L: none have the center distance close enough for me
08:01 PM Tom_L: like your car
08:01 PM Tom_L: VVVV
08:01 PM rue_shop3: I hav to do another run of handles and stuff for the sprayers
08:01 PM Tom_L: they run quieter and i think handle more hp
08:01 PM rue_shop3: that order of 18 sprayers prettymuch wiped out our stock
08:01 PM Tom_L: sellin a few ehh?
08:02 PM rue_shop3: just that one order
08:02 PM Tom_L: that's a good problem to have
08:02 PM rue_shop3: :)
08:02 PM rue_shop3: we dont expect another order this year
08:02 PM Tom_L: have you used any of the machined triggers i sent?
08:02 PM rue_shop3: the bank is making more in account fees than we make
08:02 PM rue_shop3: I think he said he did
08:02 PM rue_shop3: he's trying to use the cast ones
08:03 PM Tom_L: yeah
08:03 PM rue_shop3: dont know if he has yet
08:03 PM rue_shop3: I knew I couldn't sleep if I came out here
08:03 PM rue_shop3: took a melatonin last night
08:03 PM Tom_L: i probably don't need the flanges like the pulleys i currently have
08:03 PM rue_shop3: nightmares the whole night
08:03 PM rue_shop3: cant win
08:03 PM Tom_L: does that do it for you?
08:04 PM rue_shop3: no?
08:04 PM rue_shop3: dunno whats up
08:04 PM Tom_L: melatonin cause nightmares?
08:04 PM rue_shop3: never before
08:05 PM rue_shop3: dont think its the cause
08:06 PM rue_shop3: so my encoder-controlled-DAC works
08:06 PM Tom_L: cool
08:06 PM rue_shop3: I can use that in the pwoer supply
08:06 PM rue_shop3: that I'm not getting built

08:18 PM rue_shop3: there can only be a finite number of them
08:18 PM rue_shop3: so, at some point its not a new project
08:21 PM Tom_L: cat chasing the tail?
08:21 PM rue_shop3: not if I dont start the same project twice
08:22 PM rue_shop3: but I'm out of space for storing projects
08:27 PM aandrew: you just built a shed
08:27 PM aandrew: should've built two
08:27 PM aandrew: Tom_L: damn, $300/axis?
08:28 PM Tom_L: ?
08:28 PM rue_shop1: I can take up an infinite amount of space
08:28 PM Tom_L: not bad for servo
08:28 PM rue_shop1: its better that it just not be available
08:28 PM Tom_L: but i'd be using it on a spindle
08:28 PM aandrew: seems stupid expensive unless you're trying to move a lot of weight Ig uess
08:29 PM rue_shop1: I think I'm an order of magnitude low on energy
08:29 PM aandrew: I am
08:29 PM aandrew: today I just can't seem to wake up
08:29 PM rue_shop1: and my targets are freyed
08:29 PM aandrew: and it's 21h30

09:15 PM ShopMoon: rue_shop1: I DID!!!!!!
09:15 PM ShopMoon: \
09:15 PM rue_mohr: ij
09:15 PM rue_mohr: ok
09:16 PM ShopMoon: ITS THE BEST EVER HOLY FUCK BALLS!
09:17 PM zhanx_workshop: rue_mohr, you see my message on mylar as a reflector?
09:17 PM Tom_L: sun tanning?
09:17 PM Tom_L: :)
09:17 PM zhanx_workshop: lol so as parabolic reflectors
10:04 PM Tom_L: so what's the easiest way to get a -10v supply say 500ma - 1A or so
10:05 PM Tom_L: (excluding an atx supply)
10:33 PM rue_mohr: no
10:33 PM rue_mohr: do they still have a -12V supply, I think they do
10:34 PM Tom_L: yeah
10:36 PM Tom_L: just wonder how you're supposed to arrive at a -10 ~ +10v control supply for these amps
10:45 PM rue_mohr: you can use 0-10V or 4-20mA
10:45 PM rue_mohr: every time I need to show you that something handles it all I'm right... so far
10:45 PM rue_mohr: the signals themself are meaningless
10:45 PM rue_mohr: you program what the range means to the controller
10:46 PM rue_mohr: aka stop can be 0, 1, or 3.14V
10:46 PM rue_mohr: depeneding how you program it
10:46 PM rue_mohr: 1000 rpm can be 0.5V if you want
10:46 PM rue_mohr: :)
10:47 PM rue_mohr: we can set ya up with a -10 ->10V amp from the -12 to 12 of an atx
10:47 PM rue_mohr: :/ I'm almost asleep
10:47 PM rue_mohr: wanted to do things
10:59 PM zhanx_workshop: one day thingiverse will work and then the site will die

11:48 PM rue_shop1: ok, how me!
11:49 PM rue_shop1: want to see what you use for a heater, and how you get it out of the way to mold
11:49 PM rue_shop1: mine is still half built on the deck
11:55 PM zhanx_workshop: ok
11:56 PM zhanx_workshop: i have a spool (100 feet of nicrome wire)
