07:02 AM Tom_L: Merry Christmas!
09:58 AM polprog: thanks Tom_L, merry christmas to you too :)
09:58 AM polprog: i feel like building another VFD inverter
09:59 AM polprog: maybe id be able to get both +20 odd V for the grids and the low voltage ac for the filament
12:41 PM rue_mohr: merry christmas
12:42 PM rue_mohr: not that I was sure today was, but yea!
12:42 PM rue_mohr: polprog, go for the 20V part and the filament can just tag along
12:59 PM polprog: hmm
12:59 PM polprog: rue_mohr: its the idea that counts
01:00 PM polprog: apropos whishtling thread
01:00 PM polprog: i was unable to find the exact handshake carrier tone frequency on the net
01:01 PM polprog: you know the one the modem emits when starting the hanshsake
01:01 PM polprog: nothing on the net
01:02 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/xilinx/New_Board/
01:02 PM Tom_L: sample .v files for the board i'm getting
01:02 PM Tom_L: good samples
01:04 PM Tom_L: .v = verilog
02:51 PM polprog: ill check it out in a sec
02:51 PM polprog: i should lay out a board, a univerasal boost converter
02:52 PM polprog: that allows you to mount any common mode choke or a transformer pulled out of an smps
02:52 PM polprog: having all the other parts on it
02:52 PM polprog: im experimenting with dcdc converters
02:52 PM polprog: the previous one used a 1u choke and variable duty cycle
02:53 PM polprog: this one uses a transformer and im planning to make the feedback control the square signal on/off
02:53 PM polprog: so the mosfet will be either constantly switched on/off or kept off
02:56 PM polprog: but the idea is that you have a board that you would attach the choke/transformer with a zip tie, solder 2 or 4 wires and go
05:23 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/switcher.png
05:23 PM Tom_L: there's my buck converter
05:23 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/5v_switcher.jpg
06:14 PM rue_shop1: heh, I dont remmeber that one
06:18 PM Tom_L: cheaper to buy from china
06:18 PM Tom_L: even for just the digikey parts
06:19 PM Tom_L: i might have parts for a few more but i dunno
06:20 PM Tom_L: nope, no boards
06:21 PM Tom_L: i got programmer boards out the wazoo
06:21 PM Tom_L: you run short on U2 experimenters i still got some of those made up
08:14 PM rue_mohr: I didn't get into the usb stuff, I'm reserving them for it
08:16 PM Tom_L: i could get some of these samples to work on my old board. the resources are there for some
08:16 PM Tom_L: i'll probably just wait
08:34 PM rue_shop1: trying to stay awake
08:34 PM rue_shop1: working on the water dispenser
08:35 PM Tom_L: what's wrong with it?
08:36 PM rue_shop1: I need to build a controller for it, I just got the keyboard connected
08:42 PM Tom_L: did i ever send you a 4x4 matrix keypad?
08:42 PM Tom_L: just found a couple in a box i've had forever
09:08 PM rue_mohr: dont think so
09:09 PM rue_mohr: is it one of the membrane ones?
09:09 PM Tom_L: no
09:09 PM Tom_L: i doubt i have a pic of it
09:10 PM Tom_L: one of these samples displays the kbd scancodes on the 7 seg display
09:11 PM Tom_L: they use a different style of programming which is interesting
09:14 PM rue_mohr: I'v become realyl friendly with the scanless decoders
09:15 PM rue_mohr: 4 diodes, 2 transistors and it just hands over the keycode
09:17 PM Tom_L: this is more for fun for me
09:27 PM rue_mohr: I will get to deal with key bounce
09:28 PM rue_mohr: knowing that a persons max push-rate is 10Hz helps
09:28 PM rue_mohr: wait a 20th of a second after the key goes away
09:35 PM Tom_L: oh.. they have a debounce sample too
09:35 PM Tom_L: the guy is crap to deal with (slow) but so far i'm pretty happy with the software
09:38 PM rue_mohr: you cant order from china and demand the fastest to arrive, best product ever
09:38 PM rue_mohr: they only do 1 of the 3 things
09:38 PM rue_mohr: cheap
09:39 PM Tom_L: i usually get a reply within a week though
09:39 PM Tom_L: asked for tracking and didn't get it
09:40 PM rue_mohr: support for an fpga baord?
09:40 PM rue_mohr: your in the usa
09:40 PM rue_mohr: the usa pissed off china
09:40 PM rue_mohr: that trump guy
09:40 PM Tom_L: they still want our money
09:40 PM Tom_L: they want it so bad they print it
09:41 PM rue_mohr: they are working on chaning the unit they trade in
09:41 PM rue_mohr: countries around the world are bailing to get away from us money
09:41 PM Tom_L: i'm convinced anybody in office from here on won't be worth a crap
09:41 PM rue_mohr: agreed
09:41 PM Tom_L: there are none left with scruples
09:42 PM rue_mohr: dunno whats gonna happen
09:42 PM Tom_L: i don't watch news
09:42 PM rue_mohr: me either
09:42 PM rue_mohr: I get a bit of junk perphially thru twitter
09:43 PM rue_mohr: https://twitter.com/RueNahcMohr/status/1210035606039842817
09:43 PM rue_mohr: there is a thing for ya
09:43 PM rue_mohr: posting videos on twitter is addictivly easy
09:44 PM Tom_L: the keypads i have are 4 x 4 and button not membrane
09:44 PM Tom_L: yeah
09:45 PM rue_mohr: I have some 16 key, but I wanted to make door entry pads as the commercial ones are $300 ea
09:45 PM rue_mohr: and wtf?
09:47 PM rue_mohr: https://www.aliexpress.com/item/32985597508.html
09:48 PM rue_mohr: https://www.nortekcontrol.com/products/access-control-systems/stand-alone-access-control/232i-indoor-flush-mount-keypad/ <-- $300
09:49 PM Tom_L: that keypad looks just like the ones i've got but 3x4
09:49 PM rue_mohr: probably is
09:49 PM Tom_L: the one on the $$$ one
09:50 PM rue_mohr: sorry I'm exhausted
09:50 PM rue_mohr: gonna turn in
09:50 PM Tom_L: i'm about to
09:50 PM Tom_L: gotta work tomorrow
09:51 PM rue_mohr: I'm clear till 2nd
09:51 PM Tom_L: i figured
09:51 PM rue_mohr: should watch the phone for emergencies tho
09:51 PM Tom_L: you drivin your truck or company truck?
09:53 PM rue_bed2: I'm trying not to drive my truck
09:53 PM rue_bed2: they said to not worry about chaff from the gear, its basically asbestos
09:54 PM Tom_L: it's grit
09:54 PM rue_bed2: as I said I dont want to comtaminate the oil and their saying not to worry about it
09:54 PM rue_bed2: yea
09:54 PM Tom_L: so minimize it if at all possible
09:54 PM rue_bed2: I dont need extra in there
09:54 PM rue_bed2: I'v ordered another gear, I'm gonna measure it agianst the orig
09:54 PM Tom_L: after they finally fix it, change the oil & filter no matter what
09:54 PM rue_bed2: I think they installed it wrong
09:55 PM rue_bed2: I know they didn't pull the cam, they even said so
09:55 PM rue_bed2: so I dont think its on right
09:55 PM rue_bed2: yep
09:55 PM Tom_L: it would be hard to get it right and measure the clearance unless it was out of the vehicle
09:55 PM rue_bed2: they did a oil /filter aleady, but thats almost pointless
09:55 PM rue_bed2: yep
09:56 PM Tom_L: at least they're willing to make it right
09:56 PM rue_bed2: they said that pulling the cam can cause issues, I'm not completely sold
09:56 PM rue_bed2: so they say
09:56 PM Tom_L: it's more work
09:56 PM rue_bed2: lots more
09:56 PM Tom_L: is it pushrod or ohc?
09:56 PM rue_bed2: remove intake manifold, lifters, rad, front grill
09:56 PM Tom_L: no ohc...
09:56 PM Tom_L: nevermind
09:57 PM Tom_L: ohc would be belt drive
09:57 PM Tom_L: or chain
09:57 PM Tom_L: in my younger years i was a mechanic
09:57 PM Tom_L: foreign & domestic
09:57 PM rue_bed2: I'm just worried that they are considering my truck disposable and dont care if their fix makes the whole thing die in 5 years
09:58 PM Tom_L: they better not
09:58 PM Tom_L: they are a certified GM dealer
09:58 PM rue_bed2: I told them about the 5 mechanics I consulted on about this from around north america
09:58 PM Tom_L: you have leverage there
09:58 PM rue_bed2: where is Z anyhow?
09:59 PM Tom_L: how did they respond to that?
09:59 PM Tom_L: i dunno
09:59 PM Tom_L: maybe he went to see family
09:59 PM rue_bed2: one of the guys who was there said he'd been working on it
09:59 PM rue_bed2: he said they were really really sure it wasn't out by a tooth in the way somone does when it took 3 times to get it right
10:00 PM rue_bed2: can you tell in those images
10:00 PM Tom_L: which?
10:00 PM rue_bed2: if the crankshaft key is a slot or a machined-in ridge on the crank?
10:00 PM Tom_L: they have woodruff keys
10:01 PM Tom_L: half moon probably
10:01 PM rue_bed2: ok, cause they would have cut into the key when they changed the .... the cam gear
10:01 PM rue_bed2: did I show you the images of the cam gear?
10:01 PM Tom_L: they wouldn't machine a ridge on the crank
10:01 PM Tom_L: i don't think so
10:01 PM rue_bed2: k, remind me tommorow
10:02 PM rue_bed2: I cant tell the year on it, I'd like to know if its the second set
10:03 PM rue_bed2: the cam gear had a steel hub, they snapped the gear away and slit the hub to expand it and get it off
10:03 PM rue_bed2: in the process cutting thru a key I dont know if they replaced
10:03 PM Tom_L: yeah too hard to pull a pressed gear in vehicle
10:04 PM rue_bed2: totally
10:04 PM Tom_L: hope none of the shavings got in the pan
10:04 PM rue_bed2: and the old gear was stripped anyhow, so whatever
10:04 PM Tom_L: or anywhere else
10:04 PM rue_bed2: they did do an oil change...
10:05 PM rue_bed2: when I was eyeing the engine, I didn't see anything from cutting
10:05 PM Tom_L: did they say how they pressed the new one on?
10:06 PM rue_bed2: I think they shoved it into the (hopefully old) thrust plate
10:06 PM Tom_L: there is a plug on the backside of the engine inline with the cam
10:06 PM rue_bed2: ooo
10:06 PM rue_bed2: I'll try to check that
10:06 PM Tom_L: for castings etc
10:06 PM Tom_L: you can't see it
10:06 PM rue_bed2: feel?
10:06 PM Tom_L: it would be behind the flywheel
10:06 PM rue_bed2: drat
10:07 PM Tom_L: up above the crank
10:07 PM Tom_L: not accessible
10:07 PM rue_bed2: drat
10:07 PM Tom_L: the original is a steel puck
10:07 PM Tom_L: you've probably seen em
10:07 PM rue_bed2: yea
10:08 PM rue_bed2: they couldn't have pushed against it or it would have just pushed out
10:08 PM Tom_L: for the water galley they're called freeze plugs
10:08 PM Tom_L: i doubt they heated it to put it on being part plastic
10:09 PM rue_bed2: I dont think they bottomed it properly
10:09 PM Tom_L: i've questioned that from the beginning
10:09 PM rue_bed2: I"ll get the new gear, that will be identicle to the one they put in, and check
10:10 PM Tom_L: maybe you can measure it without having to buy it
10:10 PM rue_bed2: I dont know how much clearance there normally is to that cover
10:10 PM rue_bed2: I can
10:10 PM rue_bed2: napa said they can bring it in and send it back
10:10 PM Tom_L: i would think at least a couple mm
10:10 PM rue_bed2: and that they aren't concerned if I do
10:10 PM Tom_L: did you tell them what was going on?
10:10 PM rue_bed2: iirc, the manual said up to 50thou play to that plate
10:11 PM rue_bed2: they know
10:11 PM Tom_L: .001 to .005 endplay
10:11 PM rue_bed2: they pointed out they didn't want to realaese it
10:11 PM rue_bed2: oh, 5
10:11 PM rue_bed2: remmebered my decimal wrong
10:11 PM Tom_L: i dunno about gear to cover clearance
10:11 PM Tom_L: that was cam endplay
10:11 PM Tom_L: they wouldn't give you gear to cover clearance
10:11 PM rue_bed2: yea, I'm gonna try to talk to the wrecker, see if there are any of those engines I can poke
10:12 PM Tom_L: take some clay along and measure it that way
10:12 PM rue_bed2: ooooo
10:12 PM rue_bed2: silly putty
10:12 PM rue_bed2: cool
10:12 PM Tom_L: i know all sorts of tricks :)
10:12 PM rue_bed2: and sciors for a scoss sectin
10:12 PM Tom_L: or xacto
10:12 PM rue_bed2: yea, thats a really cool trick
10:13 PM Tom_L: we measured valve clearance that way
10:13 PM rue_bed2: ;)
10:14 PM Tom_L: i'm gonna reboot this.. don't go away
10:14 PM rue_bed2: I'm in bed :/
10:19 PM Tom_L: well that pc is screwed now
10:20 PM rue_bed2: ?
10:20 PM Tom_L: i'm not about to start fixin it now
10:20 PM Tom_L: i rebooted and now it won' boot
10:20 PM rue_bed2: went poof or OS thing
10:20 PM rue_bed2: hmm
10:20 PM Tom_L: and it needs a cd but doesn't have one
10:20 PM Tom_L: it was acting funny
10:20 PM rue_bed2: oooh, its windows wednesday?
10:20 PM rue_bed2: hardware or software?
10:21 PM Tom_L: probably software
10:21 PM rue_bed2: microsoft update?
10:21 PM rue_bed2: if it cant boot, that could mean they did an update
10:21 PM rue_bed2: their updates do that lots
10:22 PM Tom_L: i gotta find a cd for it
10:22 PM Tom_L: no drive in the pc
10:23 PM Tom_L: i never update it
10:24 PM rue_bed2: 3rd time drifting off while my finger is on a key
10:25 PM rue_bed2: voices getting loud
10:25 PM rue_bed2: "I'v got no wager" it says
10:25 PM rue_bed2: sounds concerned
10:27 PM rue_bed2: a narrator said somehting I just caught the last two words "duritic fort."
10:28 PM rue_bed2: wonder what duritic is...
10:31 PM Tom_L: ok found a cd to use
10:31 PM Tom_L: that pc is vulnerable
10:32 PM Tom_L: but i don't have anything on it i worry about
10:32 PM Tom_L: that's why i use it for irc
10:35 PM Tom_L: might be offline for a day or two
10:48 PM Tom_L: i should just plan on replacing the hdd
10:51 PM Tom_L: their 'repair' never works anyway
10:58 PM Tom_L[m]: I can still read messages from my phone
