12:53 AM rue_mohr: #7...
12:59 AM rue_mohr: (typo)
01:17 AM rue_mohr: polprog, but can you?
01:17 AM rue_mohr: I dont know if its just my browser that mauls the video
01:17 AM polprog: I can read the text fine
01:17 AM polprog: im on my phone
01:18 AM rue_mohr: oh good
01:25 AM rue_mohr: its just blur here
01:25 AM rue_mohr: so, thats no ram 6502 @ 100kHz
01:25 AM rue_mohr: Tom_L, I got the lcd working
01:25 AM rue_mohr: its cute watching it write the screen with the processor going at er... 100Hz
01:26 AM polprog: haha, good job
01:27 AM rue_mohr: thanks, its been a fight, which I didn't expect
01:27 AM rue_mohr: I'm at 3 chips now
01:28 AM rue_mohr: I'm pondering one of the transistor oscillators
01:28 AM rue_mohr: I'd like to not add a 555 as a clock source
01:28 AM rue_mohr: but at just 3 more parts, it would be SO easy
01:28 AM rue_mohr: (the method of using the 6502 as an RC osc seems REALLY unstable)
01:53 AM polprog: hmm, you could use a hct14 for these inverters you need, and for an osc ;)
01:53 AM rue_mohr: thats a chip
01:54 AM rue_mohr: I have two inverters now
01:54 AM rue_mohr: at 4, I might as well use a chip, as far as realestate goes
01:54 AM rue_mohr: I'm much less chips than ben eater
01:54 AM polprog: ben eater is bush league ;)
01:54 AM rue_mohr: who hasn't said anything yet
01:54 AM rue_mohr: bush league?
01:55 AM polprog: im kidding
01:55 AM rue_mohr: still dont know what it means
01:55 AM rue_mohr: :)
01:55 AM polprog: A phrase commonly used in (but not restricted to) baseball to describe something (usually a playing style or attitude) that is not respectable or sportsmanlike, but technically not breaking any rules of the game.
01:55 AM polprog: :^)
01:55 AM rue_mohr: heh
01:56 AM rue_mohr: what he does have is a better page on it all
01:56 AM rue_mohr: but he used all videos, which sucks
01:56 AM polprog: im kidding, he's good but his design is probably made as a learning example not as some hack like we like to do
01:56 AM rue_mohr: if I were a better editor, I could do a good page
01:56 AM rue_mohr: it is a hack tho
01:56 AM rue_mohr: that lcd can be perfectly well put right onto the bus
01:57 AM rue_mohr: and he used an io chip instead
01:57 AM polprog: ;)
01:57 AM rue_mohr: a 40 pin one
01:57 AM rue_mohr: for an lcd thats bus compatible
01:57 AM rue_mohr: he used a nand gate for address decoding
01:57 AM rue_mohr: which doesn't give him much
01:58 AM rue_mohr: I used a 74139, which gives me 8 addresses out
01:58 AM rue_mohr: (cut up a bit funny, but yea)
01:58 AM rue_mohr: I wanted to be able to have some small segments for IO
01:58 AM rue_mohr: I have 4
01:58 AM rue_mohr: one is LCD
01:58 AM rue_mohr: another will be keyboard
01:59 AM rue_mohr: and I'm pondering using another for serial
01:59 AM rue_mohr: I have space for 256kbits of Ram
01:59 AM polprog: 74139 is a 2 bit multiplexer
01:59 AM rue_mohr: yes
02:00 AM polprog: hmm
02:00 AM rue_mohr: I use one of them to break A15 and A14 into 4 segments 0x0000- 0x4000- 0x8000- 0xC000-
02:00 AM polprog: ohh, nice
02:01 AM rue_mohr: then I take and feed the 0x0000 into the other one and use A13 and A12 to break it down into 0x0000- 0x1000- 0x2000- 0x3000-
02:01 AM rue_mohr: C000- is the ROM
02:01 AM rue_mohr: cause of that stupid vector table
02:01 AM rue_mohr: I did IO as 0x0000-
02:01 AM rue_mohr: and I can diode-merge 0x4000 and 0x8000 into a RAM chip select
02:02 AM rue_mohr: might use 2 germanium diodes for that
02:04 AM polprog: im running online classes this weekend
02:04 AM polprog: and the next too
02:04 AM polprog: teaching linux an dpython
02:04 AM polprog: and*
02:05 AM rue_mohr: :)
02:05 AM rue_mohr: did you see the python turtle graphics tut I converted from apple IIe
02:05 AM rue_mohr: its the same tut that started me with computers
02:05 AM polprog: no
02:05 AM polprog: what is it
02:06 AM polprog: i dont remember what started me with computers
02:06 AM rue_mohr: http://ruemohr.org/~ircjunk/tutorials/prog/python/learn_py.html
02:06 AM rue_mohr: I'll show you the book
02:06 AM polprog: ah, python turtle
02:11 AM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1170719.jpg
02:11 AM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1170720.jpg
02:12 AM polprog: ohhh
02:12 AM polprog: its a binder book
02:12 AM polprog: :o
02:12 AM rue_mohr: THAT was a grade 5 activity that started me with computers
02:12 AM rue_mohr: after THAT class, I was curious about the cursor when the program ended
02:13 AM rue_mohr: "syntax error"
02:13 AM rue_mohr: so I asked the computer guy
02:13 AM rue_mohr: he gave me a BASIC programming book and disk
02:13 AM rue_mohr: I learned to type BASIC keywords first
02:13 AM rue_mohr: I think I can still type them faster than anything
02:14 AM rue_mohr: so I converted it to python, I made it as close as I could
02:15 AM rue_mohr: oooo
02:15 AM rue_mohr: I can use that screen as horrid ram
02:15 AM rue_mohr: didn't think of that
02:15 AM polprog: nice
02:15 AM polprog: oh haha
02:15 AM polprog: that would be cool
02:15 AM polprog: live blinkenlights
02:16 AM rue_mohr: I think there are spare characters off screen
02:16 AM polprog: is it a graphics or character lcd
02:16 AM rue_mohr: character ;(
02:32 AM rue_mohr: yea
02:32 AM rue_mohr: its even R/W
02:32 AM rue_mohr: E is backwards, which is annoying
02:33 AM rue_mohr: /E would help
03:14 AM polprog: hmm
03:14 AM polprog: i should go back to these xerox screens
03:15 AM polprog: i got them to dusplay *something*
03:15 AM polprog: i think i found the strobe line
03:20 AM polprog: back then
03:20 AM polprog: it would shift some garbage when i touched it and coupled in some noise
03:36 AM rue_bed: :)
04:12 AM Tom_L: cool
05:47 AM polprog: it uses chips
05:47 AM polprog: https://polprog.net/rozne1/ircjunk/xerox_lcd/
10:45 AM polprog: https://blog.regehr.org/archives/1653
12:06 PM rue_mohr: oh good, did you trace mostof the connections?
01:59 PM polprog: yea but i havent touched it
01:59 PM polprog: i only traced whats in that file
02:00 PM polprog: currently out of town, and im dead tired
02:00 PM polprog: maybe tomorrow
02:22 PM rue_shop1: https://wilsonminesco.com/6502primer/basic6502schem.jpg (ref)
02:23 PM rue_shop1: http://retro.hansotten.nl/wp-content/uploads/2017/05/osi300circuit-1024x775.jpg
02:35 PM aandrew: Hand drawn schematics... mmm
02:36 PM aandrew: I have to admit I’ve become enamoured with rue_mohr’s eprom 8-bit 7seg decoder idea
02:36 PM rue_mohr: somehow I trust a hand drawn more
02:37 PM rue_mohr: what I find interesting about it is that I'v NEVER seen it done that way before
02:37 PM aandrew: I think I’d want to reimplement with a tiny fpga or something though. Something mounted on the back of the dual 7seg so it’s a breadboard component
02:37 PM rue_mohr: the duty can be much better
02:37 PM rue_mohr: :)
02:38 PM aandrew: Yeah I like how you use the eprom as a decoder and mux, with the counter doing the dirty work
02:38 PM rue_mohr: I was totally appreciating the random word sizes of an fpga when looking at it
02:38 PM aandrew: :-)
02:38 PM rue_mohr: cause, you only need the one data output per digit
02:38 PM rue_mohr: its really hard to use up an 8 bit ROM
02:39 PM rue_mohr: its more akin to a CRT raster arrangement
02:40 PM aandrew: A cpld could probably do it
02:40 PM rue_mohr: I'm a bit backlogged right now, but I'll probably make up a rom image and give it a try later
02:40 PM rue_mohr: and I need polprog to tutorial me thru a PAL
02:40 PM aandrew: Timer and cpld for common anode
02:41 PM rue_mohr: doesn't matter anode or cathode, just change the rom data polarity
02:41 PM aandrew: $1.38 onesie-twosie pricing for way more pins than I’d need
02:42 PM rue_mohr: chip?
02:42 PM aandrew: Wouldn’t need common anything then
02:42 PM aandrew: 5M40
02:42 PM rue_mohr: oo never heard of it..
02:42 PM aandrew: I think that even has an osc
02:42 PM rue_mohr: dk $1.38?
02:42 PM aandrew: Yep. CAD
02:42 PM rue_mohr: Oo
02:43 PM aandrew: I found this part with the Digi-Key mobile app. https://www.digikey.ca/product-detail/en/5M40ZE64C5N/544-2717-ND/2499440
02:43 PM aandrew: Fuck I hate when they add text to the copied link!
02:43 PM rue_mohr: ouch, pin pitch
02:43 PM rue_mohr: I recon there is a breakout
02:44 PM rue_mohr: oooooooooo intel
02:44 PM rue_mohr: what do you use to develop for it?
02:45 PM aandrew: Quartus is my guess
02:46 PM aandrew: Pin pitch isn’t a problem
02:47 PM aandrew: Supply rail is an issue, as is drive
02:48 PM aandrew: That cheap part needs external fets and logic level translation
02:49 PM aandrew: LC4032 from lattice maybe
02:50 PM aandrew: Still needs 1.8V but can work with 3.3V, had more drive too
02:52 PM aandrew: I think a pair of 7447s is probably smaller and cheaper
02:57 PM rue_shop1: its nice to have a border buffer that will atleast get ya to 3V
02:57 PM rue_shop1: 7447 not hex tho
03:00 PM aandrew: Yeah
03:05 PM aandrew: 22V10 is probably minimum useful for two segments, 16V8 if you’re doing the display mux externally
03:06 PM aandrew: 7 for seg data, 2 for MUX, one left over (blanking output for chaining maybe)
03:06 PM aandrew: $2.20 in onesie-twosie
03:07 PM aandrew: 12 inputs means you can do 8 bits, mux clock and blanking input for chaining
03:08 PM aandrew: Another input for CA/CC maybe
03:08 PM aandrew: and another for PWM for display brightness. :-)
03:09 PM aandrew: Fuck; the last thing I need is a rue-level distraction
03:16 PM aandrew: $2.86 for TSSOP, dual 7 seg is $0.93 for a single, $2.35 for a double. That’s like $7-10 for onesie-twosie BOM cost with 0.100” headers, add $0.10 for the board... I doubt anyone would buy them even at $10 which would put the necessary BOM cost at $5 in qty
03:17 PM aandrew: Especially since anyone who’s going to need such a thing is someone like rue_mohr who’s going to just make their Ir web anyway. ;-)
03:17 PM aandrew: Make their own *
03:18 PM rue_shop1: aandrew, with my design, you need BITSin+3 inputs and DIGITS outputs tho
03:18 PM rue_shop1: well, unless you can wrap an internal state machine
03:19 PM aandrew: Hmm? You need 8b in + 3, and 7seg out, no?
03:19 PM rue_shop1: nope, in that design, the '138 scanns the segments of as many displays as you want at once,
03:20 PM aandrew: You’re using the counter to both select an address “bank” and enable the correct display
03:20 PM rue_shop1: and the rom just turns on the display for the segments that are shown for its digit
03:20 PM rue_shop1: so, if you have 0000, all the segment A will be lit for the first step
03:20 PM aandrew: In that case you’d need 8 in for a byte, 16 for half word, no?
03:20 PM rue_shop1: when the 138 selects segment G, they all get disabled
03:21 PM rue_shop1: the rom needs to know what the current segment enabled is
03:21 PM aandrew: Oh I see you’ve turned it inside it inside out
03:21 PM rue_shop1: hah
03:21 PM rue_shop1: yea
03:21 PM rue_shop1: crazy eh?
03:21 PM aandrew: Indeed
03:21 PM rue_shop1: I'v never seen it done before
03:22 PM rue_shop1: it totally changes the required shape
03:22 PM rue_shop1: suddenly, I need a 4 bit rom that has like 19 address lines
03:22 PM rue_shop1: :) fpga
03:22 PM aandrew: I’d have just done 8 address lines plus two select lines and done it in a 1Mbyte eprom I think
03:23 PM rue_shop1: the numbers on muxing the inputs didn't work
03:23 PM rue_shop1: balooned the chip count
03:25 PM rue_shop1: but it opens up a cute method of having an FPGA run 6 7segment displays and keep the duty up
03:25 PM rue_shop1: well, or more than 7 digits
03:25 PM rue_shop1: its an idea to put on the shelf :)
03:25 PM polprog: i have to get rue to explain me the 7 seg eeprom thing
03:26 PM rue_shop1: polprog, so
03:26 PM polprog: also i wanted to build a small FSM using an eeprom and maybe a gal, but im so backlogged i dont have time even for the projects i should be using
03:26 PM rue_shop1: normally, you scan the digits, and switch the segments for what you want to display
03:26 PM rue_shop1: this does the opposite
03:27 PM rue_shop1: it one-at-a-time scans the segments
03:27 PM rue_shop1: and the rom tuns the display on for the segments that needs to be displayed
03:27 PM polprog: so.. for digit 1 that as segments BC lit, how does the rom entry work?
03:28 PM rue_shop1: if the input nibble for that digit is 0, then be on for segemnts A, B, D, E, F but not G
03:28 PM rue_shop1: I have a program that can help sketch everything in for all the combinations
03:28 PM polprog: so its inverted
03:28 PM rue_shop1: doing it by hand would be like a years work
03:28 PM polprog: no wait
03:29 PM polprog: do you mean all but G for 0?
03:29 PM rue_shop1: the point is, that the rom only has 1 output to the display,
03:29 PM rue_shop1: yes
03:30 PM rue_shop1: lets say, the first 4 bits are the digit to be displayed
03:30 PM rue_shop1: and the next 3 are the information for the rom on which segment is being lit
03:30 PM polprog: ahh
03:30 PM rue_shop1: ouch, this is too involved to try to explain this way
03:30 PM polprog: i see it now
03:30 PM polprog: no i get it
03:30 PM rue_shop1: ok good :)
03:31 PM polprog: you scan the 3 bits of address and the 4 bits of the digit independently
03:31 PM rue_shop1: the 4 bits in are just whatever digit you want to display
03:32 PM rue_shop1: so, the rom has an overhead of 3 bits (for segments A-G) but otherwise is just 4 bits in and 1 bit out per digit
03:32 PM rue_shop1: see, its easier to have more input bits than output bits on a ROM
03:33 PM rue_shop1: since about 1990 I been trying to find a discrete good solution do displaying hex on 7 segments without crazy amounts of hardware
03:33 PM rue_shop1: the "White Whale"
03:33 PM rue_shop1: it doesn't really even matter anymore
03:33 PM rue_shop1: but I know its out there
03:35 PM rue_shop1: the availability of 4Mbit, 16 bit roms doesn't help the search
03:35 PM polprog: i cant believe its easier to do that by segments than using a rom to store 16 bytes and run the Q0-Q7 to the display
03:35 PM rue_shop1: its chipcount
03:35 PM polprog: hmm
03:35 PM rue_shop1: one of the things this has going for it, is that the counter and decoder can drive any number of displays
03:35 PM rue_shop1: and the 74ls138 *can* drive leds
03:36 PM rue_shop1: so there aren't extra led drivers needed
03:36 PM rue_shop1: it depends on the size of display your trying to do too
03:37 PM polprog: hmm
03:37 PM polprog: gah
03:37 PM polprog: im too tired to think
03:38 PM polprog: no electronics today
03:38 PM polprog: tomorrow after work ill have to contiune breaking out the second rf module, to see if i get the same weird readings
03:38 PM polprog: i should order these modules too
03:56 PM polprog: modules ordered
04:07 PM polprog: buying 50R feed thru terminators
04:08 PM polprog: the seller also has: brow templates for women
04:08 PM polprog: bandanas (kit of 12)
04:10 PM polprog: a mini thermal bluetooth printer (for mobile POS)
04:26 PM rue_shop1: bluetooth printer
04:26 PM rue_shop1: huh
04:26 PM rue_shop1: wonder how much work to print to it using an arduino
04:39 PM rue_mohr: hmm tired
04:39 PM rue_mohr: 2pm
05:08 PM polprog: ted yapo is seding me a USB VNA he doesnt need
05:09 PM rue_shop1: :)
05:11 PM rue_mohr: thats quite a room of stuff, I wonder what the tubes of chips are
05:11 PM polprog: huh?
05:12 PM polprog: what room
05:12 PM rue_mohr: that he posted pictures of? am I thinking of tubetime?
05:12 PM polprog: link?
05:12 PM rue_mohr: omg that was days ago, how the hell am I gonna find it?
05:13 PM polprog: use the force
05:14 PM rue_mohr: twitter is hopeless at trying to find old content
05:14 PM rue_mohr: never use it to document a project!
05:14 PM polprog: yea
05:15 PM polprog: oh, he posted a picture of sobriety coin
05:15 PM rue_mohr: I'm following, what 110 people now? (I couldn't hold 10:1) and I dont know if I can get to yesterday morning
05:15 PM polprog: i hope ill never get a coin like that
05:16 PM polprog: sometimes im afraid ill end up there
05:17 PM rue_mohr: https://twitter.com/babbageboole/status/1317491432937041920
05:17 PM rue_mohr: him!
05:17 PM polprog: hmm. not all that much stuff
05:18 PM polprog: it always looks like this reorganizing
05:18 PM rue_mohr: https://twitter.com/babbageboole/status/1315847493372968961
05:18 PM polprog: https://www.youtube.com/watch?v=XkyBuS_BHDY
05:19 PM rue_mohr: bit crowded
05:19 PM rue_mohr: looks like lots at hand
05:20 PM polprog: yeah. the shelving makes a difference
05:20 PM polprog: oh yeah
05:20 PM polprog: ive carried most of the stuff away to the basement
05:21 PM polprog: sad to see everyone doing projects while i am overy my head with non ee stuff :(
05:25 PM rue_mohr: hah that marble machine will never get done...
05:25 PM polprog: marble machine?
05:25 PM rue_mohr: you didn't notice eh?
05:26 PM polprog: i havent been monitoring twitter recently
05:26 PM polprog: i should be watching mech lectures
05:26 PM rue_mohr: guy made a hit youtube video when he banged togethor a music playing marble machine
05:26 PM polprog: ah that
05:26 PM rue_mohr: so after, he wanted to design a new one
05:26 PM polprog: yeah, it showed up several times but i never watched it
05:27 PM rue_mohr: he's missed the target of "just get it done"
06:01 PM rue_shop1: hmm
06:01 PM rue_shop1: awkward board to build, its almost all inputs
06:01 PM rue_shop1: nothing to let me know if its working ok
06:14 PM Tom_L: experience should tell you if it's right
06:15 PM Tom_L: talk to her
06:25 PM rue_shop1: I suppose I have to get the serial port up first
06:26 PM rue_shop1: I'll be worried the day I find myself reffering to a board as a her
06:27 PM polprog: well, if she would be flat on both sides...
06:28 PM Tom_L: hah
06:53 PM rue_mohr: shoudl I got shopping tommorow?
06:53 PM rue_mohr: r today, I'm dead tired
06:53 PM rue_mohr: I just wnt to sleep
06:53 PM rue_mohr: need more oxygen to my brain
06:53 PM rue_mohr: hey I wonder
06:53 PM polprog: i should sleep too
06:53 PM rue_mohr: if I should make myself up a oxygen mask
06:53 PM polprog: 0200
06:54 PM rue_mohr: that would sinch it as the source of the problem
06:54 PM Tom_L: called about my spindle motor yesterday and he said call back next week for an update
06:54 PM rue_mohr: ouch
06:54 PM Tom_L: it's a custom order from china
06:54 PM Tom_L: so i knew it would take a bit
06:55 PM rue_mohr: oh, orders from china aren't going well in the states right now I think
06:55 PM rue_mohr: how long has it been?
06:55 PM rue_mohr: almost a month?
06:55 PM Tom_L: 7 weeks + a few days
06:55 PM Tom_L: almost 2 months
06:56 PM polprog: I ordered two passthru 50 ohm bnc terminators from china
06:57 PM polprog: claimed 30 days shipping time
06:57 PM polprog: no need to hurry
06:57 PM rue_mohr: k
06:57 PM Tom_L: well we all know it takes a good month to get anything from china
06:57 PM Tom_L: with the covid that just doubles it
06:58 PM polprog: i cant believe noone sells these locally
06:59 PM polprog: nighters
06:59 PM Tom_L: buy bye
07:27 PM rue_shop1: ok, power is finished up to the mega8
07:27 PM rue_shop1: and its got reest
07:28 PM rue_shop1: wish I knew more about whats going on with z
07:28 PM rue_shop1: that was kinda ambigious,
07:28 PM rue_shop1: he dissapears for spans too
07:28 PM rue_shop1: so how the hell supposed to be sure of anything
07:29 PM rue_shop1: :/
07:32 PM Tom_dev: you're not
07:32 PM Tom_dev: he's aparently not stable
07:33 PM rue_shop1: he said 4 more treatments
07:34 PM rue_shop1: not sure if that leaves the clock still ticking or not
07:35 PM Tom_L: he's got kidney failure
07:35 PM Tom_L: and is on the KETO diet
07:35 PM Tom_L: which contributes to kidney problems
07:35 PM rue_shop1: hmm
07:35 PM Tom_L: he knows that
07:35 PM rue_shop1: he said cancer
07:35 PM Tom_L: i'm sure he's taking stuff to combat it
07:35 PM rue_shop1: ugh
07:35 PM Tom_L: i dunno about the cancer part
