#garfield Calendar

12:22 AM rue_bed: ah!
12:29 AM rue_bed: I thought they may have changed the name!
12:29 AM rue_bed: thanks
12:29 AM rue_bed: is that available for linux, I can dig later
01:00 AM rue_bed: comparing the sources
01:01 AM rue_bed: yea, the rom programming fn's were not removed, they were just delisted
01:01 AM rue_bed: the code is all still there
01:01 AM rue_bed: I'll try to assemble the orig source, work out the changes to the 8051 version
01:02 AM rue_bed: get the source back for it,
01:02 AM rue_bed: modify from there
02:58 AM polprog: http://ruemohr.org/~ircjunk/art/frog.png
02:58 AM polprog: this is nice
08:46 AM rue_bed: heh, from a dream iirc
09:24 AM rue_mohr: polprog, so I'm working on converting the 8052 source to work with the a31 assembler
09:28 AM aandrew: rue_mohr: what were you casting yesterday?
09:29 AM aandrew: I had a dream a couple nights ago that my house burned to the ground
09:29 AM aandrew: like totally burned, nothing but the foundation left
09:29 AM aandrew: which is a little weird becuase it's brick construction
09:30 AM rue_mohr: hmm
09:30 AM rue_mohr: hot sire
09:30 AM rue_mohr: I did two things,
09:30 AM rue_mohr: one is a stand-off for a linear rail on a cnc machine
09:30 AM rue_mohr: the other is an end for a project case
09:30 AM rue_mohr: no particular project
09:33 AM aandrew: nice
09:33 AM aandrew: one of my 86,145,144,091.25 projects is to turn this electric kiln into a forge
09:34 AM rue_mohr: hmm
09:34 AM aandrew: it's quite large though, so it's more a project to remove the firebrick and make a much smaller version
09:34 AM rue_mohr: whats the difference there?
09:34 AM rue_mohr: hmm
09:34 AM aandrew: I don't need a 3' dia x 3' deep kiln
09:35 AM aandrew: 6" or so and 12" deep would be more than enough
09:35 AM aandrew: ideally designed around a nice crucible
09:35 AM rue_mohr: I wonder what inductive offers
09:36 AM aandrew: not inductive, just normal kiln nichrome elements
09:36 AM rue_mohr: yea, but
09:36 AM aandrew: instead of a big propane flame and gas, it's just plug in and go
09:36 AM rue_mohr: kinda, but I wonder if inductive would be less power
09:36 AM rue_mohr: it wouldn't have as much heat all over the place
09:37 AM rue_mohr: polprog, did you write a program to self-reverse a board?
09:38 AM rue_mohr: suddenly I find myself in this sea of porting software
09:38 AM aandrew: can you induce eddy currents into aluminum?
09:38 AM rue_mohr: I'd like to: apple IIe basic -> 8051
09:39 AM rue_mohr: 8051 basic -> z80
09:39 AM rue_mohr: aandrew, yup
09:39 AM rue_mohr: conductor, magnetic field, current
09:40 AM aandrew: hm apparently you can
09:40 AM aandrew: inductive furnace for alu would definitely be more efficient
09:41 AM aandrew: e.g. https://www.youtube.com/watch?v=_9ZK_Hs99FU
09:42 AM rue_mohr: you cant use it for cooking out molds tho
09:43 AM rue_mohr: or melting down scrap pla
09:43 AM aandrew: that is true
09:43 AM aandrew: I'm presently not doing either
09:43 AM aandrew: well I'm not doing ANYTHING right now
09:43 AM aandrew: um
09:43 AM aandrew: that guy is heating an iron crucible
09:43 AM aandrew: not heating aluminum
09:44 AM aandrew: graphite crucible
09:45 AM rue_mohr: damn, I have to go
09:45 AM rue_mohr: like 10 mins ago
09:57 AM aandrew: stay and chat
09:57 AM aandrew: work can wait
01:16 PM polprog: rue_mohr: not quite yet
01:16 PM polprog: but i could implement your idea.. just need to print out a port status along with the address
01:17 PM polprog: i could make it detect a memory range by looking for port changes
01:26 PM polprog: huh, Z80180 has no gpio
01:38 PM polprog: very strange mcu
03:15 PM Tom_L: http://www.zilog.com/docs/z180/um0050.pdf
03:22 PM Tom_L: everything you ever wanted to know about it and more
05:48 PM rue_mohr: no
05:49 PM rue_mohr: just check the bit you use for feedback, and its its 0, print the address your on
05:49 PM rue_mohr: oh
05:49 PM rue_mohr: hmm
05:49 PM rue_mohr: let me think
05:49 PM rue_mohr: well, I'll stick with 8051 then
05:50 PM Tom_L: hah
06:24 PM rue_mohr: ok
06:25 PM rue_mohr: I'm kinda tired
06:25 PM rue_mohr: if I were to hurry, I could probably do a casting
06:25 PM rue_mohr: maybe a standoff for the Z axis
06:27 PM Tom_L: time is wastin!
06:27 PM rue_mohr: during winter I can rewrite intel 8052 basic
06:28 PM rue_mohr: I could spin up a mold for a hub for the cnc machine X axis (the big cnc)
06:28 PM rue_mohr: might be easier to 3d print
06:28 PM rue_mohr: the mold
06:28 PM rue_mohr: I need to learn to use cores in molds
06:29 PM Tom_L: explain
06:29 PM rue_mohr: donut
06:29 PM * Tom_L takes a bite
06:29 PM rue_mohr: molding it is a problem because the sand in the middle wont stay
06:29 PM Tom_L: ahh
06:29 PM Tom_L: not sticky enough
06:29 PM rue_mohr: but if you mold it without the hole, and place a pre-made core in
06:29 PM rue_mohr: well
06:30 PM rue_mohr: you have to free the mold, usually by bumping it around
06:30 PM rue_mohr: and that breaks the middle loose
06:30 PM rue_mohr: that case-end I made?
06:30 PM rue_mohr: took a LOT of filing to get the handle back
06:30 PM Tom_L: yeah
06:31 PM rue_mohr: thankfully, the cast aluminum files nice
06:31 PM Tom_L: too much sweat equity
06:31 PM rue_mohr: well, to get some shoulders back I have to mill it
06:32 PM rue_mohr: you could make the goal from a block pretty fast
06:32 PM Tom_L: what's that?
06:32 PM rue_mohr: https://twitter.com/RueNahcMohr/status/1429619462437801985
06:33 PM rue_mohr: (when it finally comes up) see the case side?
06:33 PM rue_mohr: its clever the plate is just bolted beween the sides and its a case
06:33 PM Tom_L: yeah i wondered what that was
06:34 PM rue_mohr: the mold was super simple, and it came out kinda heavy
06:34 PM rue_mohr: as you can see the orig is hollow
06:34 PM Tom_L: it looks heavy
06:35 PM rue_mohr: I was trying to convince myself I could just bang out molds as simple wood shapes, and I picked a bad example
06:35 PM rue_mohr: we lost wings
06:37 PM Tom_L: damn we did
06:37 PM Tom_L: where did he go?
06:37 PM rue_mohr: dunno
06:37 PM rue_mohr: when he go?
06:37 PM rue_mohr: :)
06:37 PM Tom_L: not sure
06:37 PM rue_mohr: me either
06:38 PM rue_mohr: ok, for the bearing adapters to the pipe...
06:38 PM rue_mohr: kinda like...
06:39 PM rue_mohr: its a hockey puck
06:39 PM rue_mohr: huh
06:39 PM rue_mohr: I.....
06:39 PM rue_mohr: am probably the only canadian who doen't HAVE a hockey puck
06:39 PM rue_mohr: *sigh*
06:40 PM rue_mohr: t=
06:41 PM Tom_L: hahhaha
06:41 PM Tom_L: i used to have shoebox full even
06:42 PM rue_mohr: ooooo
06:43 PM rue_mohr: I can cast the sprockets right into hubs!
06:43 PM Tom_L: center on the lathe later?
06:44 PM rue_shop3: yea
06:44 PM rue_shop3: moon made a mess in the shop
06:45 PM rue_shop3: t = 4cm
06:45 PM rue_shop3: d=
06:45 PM rue_shop3: 6cm
06:46 PM Tom_L: well tell moon to clean it up
06:47 PM rue_shop3: heh
06:47 PM rue_shop3: hey, that other fpga program
06:47 PM rue_shop3: they make it for linux?
06:48 PM rue_shop3: I'm amazingly tired
06:49 PM Tom_L: i haven't looked at vivado yet
06:49 PM Tom_L: Install Vivado HLx 2017.1 WebPACK on Ubuntu 16.04
06:49 PM Tom_L: Download Vivado HLx 2017.1: WebPACK and Editions - Linux Self Extracting Web Installer.
06:49 PM Tom_L: Open a terminal and run: $ chmod +x Xilinx_Vivado_SDK_2017.1_0415_1_Lin64.bin $ sudo ./Xilinx_Vivado_SDK_2017.1_0415_1_Lin64.bin.
06:50 PM Tom_L: https://www.xilinx.com/support/documentation-navigation/design-hubs/dh0013-vivado-installation-and-licensing-hub.html
06:52 PM rue_shop3: found something, conduit caps
06:52 PM rue_shop3: nice
06:52 PM rue_shop3: thanks
06:53 PM Tom_L: i'm pretty sure there is a free version
06:53 PM Tom_L: i can ask the guy in lcnc but i think there is
06:53 PM rue_shop3: oh thats not free?
06:54 PM rue_shop3: I'll play with it later
06:54 PM rue_shop3: I assume its a free liscence
06:54 PM rue_shop3: maybe not
06:58 PM Tom_L: i need to find out cause i dunno
07:00 PM rue_shop3: I'm going to try casting these with the impression trick
07:04 PM Tom_L: well make a good impression :)
07:04 PM Tom_L: i don't have anything that needs vivado
07:11 PM Tom_L: https://www.xilinx.com/support/download.html
07:13 PM Tom_L: there you go
07:38 PM rue_shop3: okI thin kI got th mold
07:41 PM Tom_L: poured?
07:41 PM Tom_L: or ready to pour..
07:50 PM rue_mohr: putting on shoes for pouring..
07:55 PM rue_shop3: poured
07:55 PM rue_shop3: I'm only using up about 7 hard drives at a time
07:55 PM rue_shop3: with the number of them I have, i need to be using more
07:56 PM Tom_L: hah
07:56 PM Tom_L: having too much resource... never a problem
07:57 PM rue_mohr: its been under a peice of roofing in the yard for like 2 years now
07:58 PM Tom_L: so you're clearing space AND making stuff!
08:01 PM rue_mohr: trying
08:01 PM rue_mohr: I didn't start into the cnc scrap yet
08:02 PM rue_mohr: the plate offcuts
08:19 PM rue_mohr: ok so, I have to go break out the castings later
08:19 PM rue_mohr: but now can I sleep?
08:19 PM rue_mohr: or rewrite intel 8052 basic
08:25 PM Tom_L: NO! i wanna see what you poured!!!
08:27 PM rue_mohr: its still cooling
08:28 PM rue_mohr: their 4cm thick, 6cm dia pucks
08:28 PM rue_mohr: in a while we can see how they came out
08:28 PM Tom_L: did you put sprockets in em?
08:28 PM rue_mohr: I'm trying to think how to pour around the sprockets
08:28 PM rue_mohr: not yet
08:29 PM rue_mohr: I think I have to do it as a split mold, which is ok, but a bit more trouble
08:29 PM Tom_L: sprocket at the split
08:29 PM rue_mohr: the parting line would be down the middle of the puck, so I do it all up and drop the sprockets in before the last re-assembly of the mold
08:29 PM rue_mohr: which brings up an interesting point
08:30 PM Tom_L: would it be easier to bolt the sprockets to the pucks then machine out the center?
08:30 PM rue_mohr: I usualy put the gates at the parting line...
08:30 PM rue_mohr: I'd like to cast them in
08:30 PM rue_mohr: fer the experience of it ya know
08:30 PM Tom_L: :)
08:30 PM rue_mohr: you know :)
08:31 PM rue_mohr: I dont have a program to compile this 8051 source
08:31 PM rue_mohr: *
08:31 PM rue_mohr: there is a dos program
08:31 PM rue_mohr: I could set up the windows machine with the software and compile it
08:31 PM rue_mohr: I need to know what the binary looks like that the source creates
08:31 PM rue_mohr: so I can diff it
08:32 PM rue_mohr: see what changed
08:32 PM rue_mohr: view-source:https://www.kswichit.com/8051kit/BASIC52/basic.asm
08:32 PM rue_mohr: look at the change,...
08:32 PM rue_mohr: https://www.kswichit.com/8051kit/BASIC52/basic.asm
08:32 PM rue_mohr: look at the change list on this
08:33 PM Tom_L: what assembler builds that?
08:33 PM rue_mohr: this source is LATER than the source I been using
08:33 PM rue_mohr: yea
08:33 PM rue_mohr: a dos as51 macro assembler
08:34 PM Tom_L: i wonder why i've heard of that...
08:34 PM Tom_L: i'm sure i've not used it
08:35 PM rue_mohr: its had a tonne of minor bug fixes
08:35 PM rue_mohr: the version I'm using
08:35 PM Tom_L: nope nothing on the dos box
08:36 PM rue_mohr: Dan Karmann Aug. 1993
08:36 PM Tom_L: masm 5
08:37 PM Tom_L: best i got
08:37 PM Tom_L: can't even remember how to build a .com file now
08:37 PM rue_mohr: nice if the change log was in chronologica order...
08:39 PM rue_mohr: prolly cool enough to go break open
08:40 PM Tom_L: keil
08:40 PM Tom_L: why does that ring a bell?
08:41 PM aandrew: because it's godawful? :-)
08:42 PM Tom_L: i had a couple 'turbo' tools too but have no clue what happened to em
08:42 PM Tom_L: asm pascal ... i don't remember now
08:42 PM aandrew: yeah I used to use turbo c and then microsoft quickc
08:42 PM Tom_L: still have c5 c6
08:43 PM aandrew: I won watcom c++ and a fujitsu dot matrix printer
08:43 PM rue_mohr: just borland for me
08:44 PM Tom_L: i may have had a copy of that as well
08:46 PM rue_mohr: ok, well I touched briefly on djgpp
08:54 PM Tom_L: ironic today's processors won't even run dos
08:54 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1200732.jpg
08:54 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1200733.jpg
08:54 PM rue_mohr: what?
08:54 PM rue_mohr: sure they will...
08:55 PM rue_mohr: why wouldn't it?
08:56 PM rue_mohr: Rue? you there?
08:56 PM rue_mohr: wake up
08:59 PM Tom_L: no they won't
09:00 PM Tom_L: i7 won't
09:00 PM rue_mohr: what
09:00 PM Tom_L: no 16bit programs
09:00 PM rue_mohr: why not
09:03 PM rue_mohr: oh, you mean you cant run it from windows
09:03 PM rue_mohr: boot it tho
09:03 PM Tom_L: i'm not even sure it will boot
09:03 PM rue_mohr: yea it'll boot
09:03 PM Tom_L: i know my win7 in 64bit install won't run 16 bit apps
09:03 PM rue_mohr: no, thats windows tho
09:04 PM Tom_L: so i have to run dual boot on that
09:04 PM Tom_L: 32 & 64
09:04 PM Tom_L: and i7 won't support win7
09:09 PM rue_mohr: yea, but thats just windows
09:33 PM rue_shop3: so
09:33 PM rue_shop3: ok
09:33 PM rue_shop3: I did somthing
09:33 PM rue_shop3: I'll machine them up later
09:33 PM rue_shop3: and work out a divided mold for the sprockets
09:33 PM Tom_L: so
09:34 PM Tom_L: waht da puck! let's see em!
09:34 PM rue_shop3: ...
09:34 PM rue_shop3: <rue_mohr> http://ruemohr.org/~ircjunk/tempimage/p1200732.jpg
09:34 PM rue_shop3: <rue_mohr> http://ruemohr.org/~ircjunk/tempimage/p1200733.jpg
09:34 PM rue_shop3: 4 of 'em
09:34 PM Tom_L: is that a spraycan lid?
09:34 PM Tom_L: sure looks like it
09:35 PM Tom_L: or did you print that
09:35 PM rue_shop3: no, its a 2" PVC electrical conduit lid
09:35 PM rue_shop3: cap
09:35 PM Tom_L: ahh ok i see that now too :)
09:35 PM rue_shop3: back to back
09:36 PM Tom_L: i recall when that towel was clean
09:36 PM rue_shop3: pounding it in really fractured the sides of the impression
09:36 PM rue_shop3: hah
09:36 PM rue_shop3: yea, it was clean yesterday
09:36 PM rue_shop3: MOON
09:36 PM Tom_L: so is that sand one time use?
09:41 PM rue_shop3: hell no
09:41 PM rue_shop3: a bit more water, some stirring and sit for the night, its good to go again
09:42 PM Tom_L: you have to sift out the chunks?
09:42 PM rue_shop3: with the water they break back up
09:42 PM rue_shop3: just need to remoisturize
09:43 PM rue_shop3: between the two casting yesterday I used it all
09:43 PM rue_shop3: after, I threw it in the mixer to help stirr and re-water it
09:44 PM rue_shop3: one of the bucket seals was bad and some of it was pretty borderline dry
09:48 PM rue_shop3: I might turn the pucks down tommorow, but the important thing is that their cast
09:48 PM rue_shop3: and I used up 7 more hard drives
09:48 PM rue_shop3: would be nice to be using up like 10 at a time
09:48 PM rue_shop3: atleast
09:50 PM Tom_L: you got em all tore down?
09:50 PM rue_shop3: they still have motors and a few pins
09:50 PM rue_shop3: it all goes to the bottom of the pot
09:51 PM rue_shop3: I scoup out what I can, most of them stay tho
09:51 PM rue_shop3: thigns to cast:
09:52 PM rue_shop3: - z standoff for the small cnc
09:52 PM rue_shop3: - sproket things for the big cnc
09:52 PM rue_shop3: XY junction for the small cnc
09:52 PM rue_shop3: maybe I should cast a table for the small cnc
09:52 PM rue_shop3: hmmm
09:52 PM Tom_L: you don't want a plate for the XY thing?
09:53 PM rue_shop3: the XY thing will be a funny rectanglar ways ..thing
09:53 PM rue_shop3: I have to play with it cause my ways are 1 peice flatbar
09:53 PM Tom_L: you gonna machine that stuff on the big mill?
09:54 PM Tom_L: i didn't have that option on mine
09:57 PM rue_mohr: their kinda parallel builds
10:04 PM Tom_L: you got that vivado linux link right?
10:05 PM rue_mohr: yes
10:05 PM rue_mohr: thankyou
10:06 PM rue_mohr: its in the queue :/
