12:32 AM polprog: rue_mohr: ive only done a char lcd driver on an stm8
12:41 AM rue_mohr: https://github.com/jk128/libstm8
12:46 AM polprog: Okay :D
12:46 AM polprog: Gotta eat breakfast and rush to school
12:46 AM rue_mohr: sorry I'm forking all over the place
12:46 AM rue_mohr: a printer thing I took apart has a 78k in it
12:47 AM rue_mohr: which comes up a lot
12:47 AM rue_mohr: so..
12:51 AM rue_mohr: not sure if this RX gcc supports 78k or not
12:51 AM rue_mohr: looks like there are a lot of paywalls for 78k
12:52 AM rue_mohr: but maybe its just to have them compile it for you
12:52 AM rue_mohr: I suppose I'll see
02:09 AM Ear-Wax is now known as WormFood
02:50 AM polprog: Maybe sdcc supports it
02:50 AM polprog: I never heard of this arch
03:53 AM rue_mohr: looks alot like z80
03:53 AM rue_mohr: come to think of it, it goes back quite a ways
03:54 AM rue_mohr: the old impact printers had versions of them
04:48 AM Tom_L: morning
04:52 AM rue_mohr: oh no
04:56 AM Tom_L: oh yes
04:58 AM Tom_L: stm8 use jtag?
04:58 AM rue_mohr: no
04:58 AM rue_mohr: its serial
04:59 AM rue_mohr: 115200
04:59 AM rue_mohr: but
04:59 AM rue_mohr: rs422 or soemthing
04:59 AM rue_mohr: like, siplex
05:02 AM rue_mohr: I should go lay in bed till my alarm clock goes off
05:03 AM rue_mohr: or have breakfast and a shower?
05:03 AM rue_mohr: I'v had no sleep
05:09 AM Tom_L: you gonna regret that
05:09 AM Tom_L: better eat now so you can be on your way when it does
05:19 AM rue_mohr: plucking away at this web page for the door access system
05:20 AM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/Untitled.png
05:22 AM rue_mohr: figuring out lots of things that I didn't hammer out in the design doc :)
07:26 AM Tom_L: getting there
09:16 AM rue_mohr: lots of design stuff I didn't think of
04:22 PM polprog: stm8 uses SWIM, which is bidir serial iirc
04:24 PM rue_mohr: yes, it looks like an rs422
04:24 PM polprog: isnt 422 differential full duplex?
04:24 PM rue_mohr: isn't 485 full and 422 half?
04:25 PM polprog: the other way around
04:25 PM rue_mohr: oops
04:25 PM polprog: happens to the best
04:25 PM rue_mohr: :) the things we need to know to make these mistakes in the first place
04:25 PM polprog: yeah!
04:26 PM rue_mohr: oh yea, wiat its not differential
04:26 PM rue_mohr: single ended open collector
04:27 PM rue_mohr: k, well
09:09 PM rue_bed2: 7PM, ok
09:10 PM rue_bed2: still thurs, right?
09:10 PM rue_bed2: yea ok
09:13 PM rue_bed2: when did I fall asleep
09:13 PM rue_bed2: wow
09:15 PM rue_bed2: shed supply package, need to do that
09:19 PM rue_bed2: cant find the todo list
09:19 PM rue_bed2: damn
09:20 PM rue_bed2: todo: taxes, shed package, strip down printers, cuttings,
09:20 PM rue_bed2: I had a really odd dream
09:52 PM Tom_L: trying to think of a good 4-1 prank
09:53 PM rue_mohr: oh
09:53 PM rue_mohr: right
09:53 PM rue_mohr: damn I have a busy day tommorow too
09:53 PM Tom_L: yeah but it's friday
09:53 PM Tom_L: odd day here
09:54 PM Tom_L: 33f snow in the am then ~60f in the afternoon and you'd never know it snowed
09:54 PM rue_mohr: heh
09:54 PM Tom_L: the most snow on this day here in over 130 years
09:56 PM Tom_L: didn't stick to the streets etc but piled up on the grass
10:03 PM Tom_L: so i stopped by HF and looked at their tumblers today
10:04 PM Tom_L: the big one is too big
10:04 PM Tom_L: the 2 cylinder one is too small i think
10:04 PM Tom_L: and i wasn't impressed with the small vibrating one
10:23 PM rue_mohr: your 4" sounded like it'd be fine
10:23 PM rue_mohr: you could use me to come over and help ya just get 'er done :)
10:24 PM rue_mohr: a shove over the cliff as it goes
10:24 PM Tom_L: i wanted to see how they looked
10:24 PM rue_mohr: did the roller ones work like that one I took pics of?
10:24 PM Tom_L: similar but smaller
10:24 PM rue_mohr: yea
10:24 PM rue_mohr: I'v never seen a roller one that large
10:25 PM rue_mohr: if I had a lot of parts I suppose I could use the cement mixer
10:25 PM Tom_L: heh
10:25 PM Tom_L: i need to evaluate space first
10:25 PM rue_mohr: you have to be good witha 4" one
10:25 PM rue_mohr: I'm just not sure its big enough for ya
10:26 PM Tom_L: it probably would be
10:26 PM rue_mohr: do you have a small induction motor from a bathroom fan like thing?
10:26 PM Tom_L: A9 would be the largest part i'd imagine
10:26 PM Tom_L: no i was looking for one
10:26 PM rue_mohr: scrap yard?
10:26 PM rue_mohr: electrical service contractor would have some garbage ones likley
10:27 PM rue_mohr: for ~$22 they have those inline duct booster fans
10:27 PM Tom_L: i'm sure i could find something... it just hasn't hit me yet to be motivated on this
10:27 PM rue_mohr: at rona or what have you
10:27 PM rue_mohr: ah
10:27 PM rue_mohr: well, you got the wheels
10:27 PM Tom_L: it was a thought
10:27 PM rue_mohr: and the pipe section
10:28 PM Tom_L: yeah i'll keep the stuff i have and ponder it some
10:28 PM rue_mohr: so, do you have some peices of plexi to use as pipe ends?
10:28 PM Tom_L: i'd just pick up the ends
10:28 PM rue_mohr: the removable end is a trick tho
10:28 PM Tom_L: cap on one and screw fitting on the other
10:28 PM rue_mohr: yea
10:28 PM rue_mohr: or screwed plate
10:29 PM Tom_L: run the rollers just inside the lips on each end
10:29 PM rue_mohr: I have to use an impact to get those screws out
10:29 PM rue_mohr: yes
10:29 PM Tom_L: put some baffles inside like an ice cream mixer
10:29 PM rue_mohr: I have one tiny angle bracket screwed to the inside
10:29 PM Tom_L: so the stuff just doesn't slide around inside
10:29 PM rue_mohr: you could make it from PVC and glue it in
10:29 PM Tom_L: one or two
10:30 PM rue_mohr: little L peice
10:30 PM Tom_L: yeah i was gonna glue and screw
10:30 PM rue_mohr: what do you have for shaft material?
10:30 PM Tom_L: dunno
10:30 PM rue_mohr: I think those bearings fit 5/16
10:30 PM Tom_L: was gonna look but got distracted
10:30 PM rue_mohr: meh
10:31 PM Tom_L: i wanted to see what the HF media looked like too
10:31 PM Tom_L: wasn't impressed
10:31 PM rue_mohr: hah, cant be worse than lava rock
10:31 PM Tom_L: :)
10:31 PM rue_mohr: it looks like the amount of colouring they put in that stuff is crazy
10:32 PM Tom_L: it was a bit big i think
10:32 PM Tom_L: just thinking what my bud used to use
10:32 PM Tom_L: need something a bit smaller
10:35 PM rue_mohr: https://www.amazon.ca/Good-Earth-Horticult-Inc-14452/dp/B000BZ8H0Y/ref=asc_df_B000BZ8H0Y/
10:35 PM rue_mohr: oh oops, nevermind :D
10:50 PM rue_mohr: if you threw in fine china, it might sort itself out
10:51 PM rue_mohr: https://www.amazon.ca/iPower-Booster-Extractor-Exhaust-Grounded/dp/B008N4QIZG/ref=sr_1_1_sspa
10:51 PM rue_mohr: hey, sean didn't meet with and get funds worked out, arg
10:51 PM rue_mohr: :/ he's havin issues
10:52 PM Tom_L: has he seen the parts?
10:52 PM rue_mohr: I dont know
10:52 PM rue_mohr: he was here but I think he ran in and out to grab sprayers to deliver
10:52 PM rue_mohr: :/
10:52 PM Tom_L: https://www.harborfreight.com/dual-drum-rotary-rock-tumbler-67632.html
10:52 PM Tom_L: i had some interest in that one
10:53 PM rue_mohr: $70 ouch
10:53 PM Tom_L: yeah
10:53 PM Tom_L: i said _some_
10:53 PM Tom_L: the rollers were about 1/2"
10:54 PM rue_mohr: it doesn't push me an image
10:54 PM rue_mohr: got a direct link?
10:54 PM Tom_L: hmm
10:54 PM Tom_L: https://www.harborfreight.com/media/catalog/product/cache/9fc4a8332f9638515cd199dd0f9238da/6/7/67632_I.jpg
10:55 PM rue_mohr: a gear...
10:55 PM Tom_L: well, the one i saw didn't
10:55 PM rue_mohr: its two seperate drums eh?
10:55 PM Tom_L: yes
10:55 PM Tom_L: a little smaller than a small coffee can
10:55 PM rue_mohr: I think I have a single drum version
10:55 PM Tom_L: if coffee cans are still a thing...
10:56 PM Tom_L: i had a rock tumbler as a kid
10:56 PM rue_mohr: I think I'v made a few
10:56 PM Tom_L: i think it drove everybody nuts
10:56 PM rue_mohr: :)
10:56 PM Tom_L: one of those induction motors would be ideal really
10:56 PM rue_mohr: well
10:56 PM rue_mohr: I could send you one
10:56 PM Tom_L: naw
10:57 PM rue_mohr: you might be decided by the time it gets there
10:57 PM rue_mohr: :)
10:57 PM Tom_L: i'm sure if i put an ounce of effort into it i could find one
10:57 PM Tom_L: something about it just doesn't excite me yet
10:58 PM rue_mohr: the only part I think your really lacking is a frame
10:58 PM Tom_L: i could make a frame
10:58 PM Tom_L: i've got plenty of aluminum
10:58 PM rue_mohr: you have wheels, bearings, pipe, you COULD use some scrap plexi as an end cap
10:58 PM Tom_L: or wood for that matter
10:59 PM rue_mohr: well, pullies
10:59 PM Tom_L: i've probably got some protein skimmer parts left too
10:59 PM rue_mohr: ?
11:00 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/skimmer/skimmer.jpg
11:00 PM rue_mohr: not familiar with that one
11:00 PM Tom_L: i made a bunch of those and sold them to a local fish store
11:00 PM rue_mohr: huh
11:00 PM Tom_L: for saltwater fish
11:00 PM rue_mohr: k
11:01 PM Tom_L: it bubbles the slime from the water
11:01 PM rue_mohr: algee?
11:01 PM Tom_L: probably
11:01 PM Tom_L: https://www.amazon.com/Protein-Skimmers-Saltwater-Aquariums/s?k=Protein+Skimmers+for+Saltwater+Aquariums
11:02 PM Tom_L: i made mine and it worked better than the ones he was selling so he wanted some
11:03 PM Tom_L: pet fish aren't much of a thing nowdays
11:03 PM Tom_L: not as much anyway
11:04 PM rue_mohr: they aren't? I have 3
11:04 PM rue_mohr: they dont meow at me continiously
11:05 PM rue_mohr: if they have a problem, they die
11:05 PM Tom_L: not like it was back then
11:05 PM Tom_L: you gotta take care of em a little
11:05 PM rue_mohr: I water them
11:05 PM Tom_L: i wound up selling mine back to the store
11:05 PM rue_mohr: I watered them last weekend
11:05 PM Tom_L: :)
11:06 PM Tom_L: none of the stores that were around then are still around
11:06 PM rue_mohr: come to think of it the fish store here closed too
11:06 PM rue_mohr: a pet store in one town still has fish
11:06 PM Tom_L: as well as birds
11:07 PM Tom_L: you don't find near as many of either as you did
11:07 PM rue_mohr: cats and dogs
11:07 PM Tom_L: not as much either
11:07 PM rue_mohr: my father had parrots he let fly around and there was poop everywhere
11:07 PM Tom_L: the one we frequented stopped selling live stock
11:08 PM rue_mohr: they liked to pry the flint out of lighters
11:08 PM Tom_L: hah
11:09 PM Tom_L: i still have a bit of that plastic around but it would be too brittle for this
11:09 PM rue_mohr: pvc is good
11:09 PM rue_mohr: takes a kicking
11:09 PM Tom_L: yeah i have some
11:09 PM Tom_L: also have a little abs
11:10 PM rue_mohr: abs is a bit thick
11:10 PM Tom_L: that white pipe is pretty thick
11:10 PM Tom_L: sch 40
11:10 PM rue_mohr: the 4" PVC?
11:10 PM rue_mohr: about 1/8"?
11:10 PM Tom_L: more
11:10 PM rue_mohr: ?
11:10 PM Tom_L: 1/4
11:10 PM Tom_L: probably
11:10 PM rue_mohr: !!
11:12 PM Tom_L: fairly heavy
11:14 PM Tom_L: time to sleep again
11:15 PM rue_mohr: but I just woke up
11:15 PM rue_mohr: hmm, ...
11:16 PM Tom_L: surprised you made it today.. you were up nearly all night
11:16 PM rue_mohr: I got home early and collapsed
