01:07 AM rue_mohr: Tom_L, still up per chance, a thought just hit me
01:35 AM polprog: some LCDs came in with the VFDs as well, incl one from a printer which is on a low pin count FFC
01:36 AM polprog: and one that literally has 6 connections going to a custom epson IC, im sure thats some serial thingt
01:36 AM polprog: thingy*
01:36 AM polprog: the epson one is color
02:08 AM rue_mohr: yep

05:02 AM Tom_L: am now..
05:30 AM polprog: one of the vfds is a Medion one, a UART module that uses some serial protocol for the text and icons display
05:31 AM polprog: apparently used in some Medion PCs as a form of bells and whishtles. Must have been cool
05:32 AM polprog: i was always a fan of small diag displays on computers
05:40 AM polprog: oh, the ft232 will be in the pickup point today
05:40 AM polprog: how nea
05:40 AM polprog: neat*
05:50 AM polprog: rue_bed: not sure if youve seen these, so far one works, one blinks, one dead. But it has a pcmcia socket with a bridge as well: https://i.ibb.co/T2rTdB2/IMG-20191105-184353-HDR.jpg
06:56 AM polprog: https://polprog.net/rozne1/ircjunk/youtubelogo.png
08:51 AM rue_mohr: hahah thats halarious!
08:51 AM rue_mohr: they put a modem IN it...
08:52 AM rue_mohr: wtf is taking up th rest of the space on the card?
08:52 AM rue_mohr: that pcb had IBM written all over it
08:53 AM rue_mohr: (not the daughtercard)
09:18 AM rue_mohr: roads still not gonna work for the van
10:14 AM polprog: thats actually HP i think
10:15 AM polprog: https://polprog.net/rozne1/ircjunk/fpga/
10:15 AM polprog: the kit
10:15 AM polprog: imma stow it now, need to revise the Newtons Equation for tomorrows lab, if i fail the entry test, ill be deemed not worty of lazer-touching
10:29 AM Tom_L: another snow day?
10:30 AM Tom_L: polprog, ur workbench is too damn clean
10:31 AM polprog: better? https://i.ibb.co/0CTBLXN/IMG-20200113-155822.jpg
10:31 AM polprog: i try to keep it clean
10:31 AM polprog: the stuff that lies on the coach goes on it when i go to sleep
10:31 AM polprog: im literally thrashing every day
10:32 AM Tom_L: nice displays... most look purpose built
02:29 PM polprog: hmm, the ft232 kits didnt come with the actual 16 pin connector, heh. thinking if i should go for the locking 16 pin ones i have
03:18 PM Tom_L: git that thing wired up!
03:18 PM polprog: i should be reading the school shite
03:22 PM Tom_L: but you're not so you may as well be doing this
03:32 PM rue_mohr: haha
03:32 PM rue_mohr: I'd say just put pins on what you need
03:32 PM rue_mohr: I soldered wires off mine with labels on the individual connectors
03:55 PM polprog: im planning to make a kit of that plus a dedicated just-jtag or jtag+uart connector that goes to individual goldpins
03:55 PM polprog: on a cable
03:55 PM polprog: and an idc on the adapter end
03:55 PM polprog: woot
03:55 PM polprog: free Keil 80c51 toolkit
03:55 PM polprog: http://pages.silabs.com/lp-keil-pk51.html
03:57 PM rue_mohr: what os...
03:57 PM rue_mohr: https://www.silabs.com/products/mcu/Pages/8-bit-microcontroller-software.aspx <-- 404
03:58 PM polprog: probably win but still useful
03:59 PM rue_mohr: max only
03:59 PM rue_mohr: mac
03:59 PM rue_mohr: j/k
03:59 PM rue_mohr: they have linux, interseting,
03:59 PM rue_mohr: and you just need to register
03:59 PM rue_mohr: https://www.silabs.com/products/development-tools/software/simplicity-studio
03:59 PM rue_mohr: maybe
04:00 PM polprog: https://www.silabs.com/products/development-tools/software.ct-software?query=8051
04:00 PM polprog: '80c51' and 'IoT' is a funny mix
04:01 PM polprog: using network adresses that are 8 4 times as big as your registers
04:01 PM polprog: 4 times*
04:01 PM rue_mohr: free cpu core
04:01 PM rue_mohr: and its really popular
04:01 PM polprog: i know, j/k
04:01 PM polprog: im sure there are some super low power versions or whatnot
04:03 PM rue_mohr: I was gonna use 8051 for the servo loops on the mecha
04:03 PM rue_mohr: cause the parallel interface can operate banks of solinoids fast
04:04 PM rue_mohr: but the stm32 can push impressive rates over 74hc595 chips
04:04 PM polprog: hmm
04:04 PM polprog: did you generate your key?
04:04 PM polprog: whats your last 4 characters?
04:04 PM rue_mohr: no, I dont kow if I want it
04:04 PM polprog: i just typed in different data in and got the same key...
04:04 PM polprog: they give it right away
04:04 PM polprog: you dont need any email act. etc
04:05 PM rue_mohr: I was designing around the ST version of the 8051, its pretty fast, and is serial flashable, BUT
04:05 PM rue_mohr: went obsolete
04:06 PM polprog: shame
04:07 PM rue_mohr: I only have a few
04:07 PM polprog: i lost the battery charger for the camera i recently take pictures of the bench
04:07 PM rue_mohr: https://www.element14.com/community/docs/DOC-73961/l/pk51-professional-developers-kit
04:07 PM rue_mohr: but whats IN the kit
04:08 PM polprog: the kit
04:08 PM polprog: duh
04:08 PM polprog: pixie dust
04:08 PM rue_mohr: yea, thats about what I can find online
04:08 PM rue_mohr: I think.... its just software
04:09 PM polprog: looks like it
04:09 PM rue_mohr: which starts to explain a lot
04:09 PM rue_mohr: "You should consider the PK51 Professional Developer's Kit if you...
04:09 PM rue_mohr: Will work with a variety of 8051 microcontrollers,"
04:10 PM rue_mohr: its not a hardware kit then...
04:10 PM polprog: i should start filing drawings and stuff
04:11 PM polprog: either get an a5 file or switch to drawing on a4
04:25 PM polprog: looking for smd sample books
04:25 PM polprog: https://www.amazon.com/Sample-Book-Author/dp/1580600638
04:33 PM rue_mohr: smd samples?
04:34 PM rue_mohr: I'm using a full size binder with 8mm film holder pages
04:34 PM rue_mohr: ok, its not 8mm, but I'll fuse some more pockets later
04:34 PM polprog: hmm, film holder
04:34 PM polprog: good ide
04:34 PM polprog: idea
04:35 PM polprog: i dont have any space to put a full size binder
04:35 PM rue_mohr: seeing as all the smd stuff was based off 8mm film
04:35 PM polprog: oh, 8mm
04:35 PM polprog: i didnt notice
04:35 PM polprog: that makes sense
04:35 PM rue_mohr: you didn't notice the smd reels are the same as film reels?
04:37 PM rue_mohr: https://www.aliexpress.com/item/32749777185.html
04:37 PM rue_mohr: the books are stupid expensive tho
04:37 PM rue_mohr: $10cad for 15 pages
04:38 PM polprog: i never had this small film reels
04:39 PM polprog: https://www.aliexpress.com/item/32752639161.html
04:39 PM polprog: this looks nice
04:39 PM polprog: i mean
04:39 PM polprog: thats a generic sample book
04:39 PM polprog: but i like the chinese writing
04:39 PM polprog: looks mysetrious to the uninitiated
04:44 PM rue_mohr: its ring, so it can be added to
04:44 PM rue_mohr: you MIGHT find a full one for about the same price
04:45 PM polprog: i found one for 110 pln, which is roughly 30 usd?
04:45 PM polprog: full one with parts in it
04:45 PM rue_mohr: https://www.aliexpress.com/item/32756218123.html
04:45 PM rue_mohr: there is a good deal
04:46 PM rue_mohr: its a standard binder
04:47 PM polprog: https://www.aliexpress.com/item/32370322093.html this is a full one for 13usd
04:47 PM polprog: 0603 resistors
04:47 PM rue_mohr: thats where you have to customize
04:48 PM polprog: ?
04:48 PM rue_mohr: part sizes and range
04:49 PM polprog: as in specify when buying?
04:49 PM rue_mohr: just what you select to buy
04:50 PM rue_mohr: if you decide to buy 1206 0805, different listings
04:50 PM rue_mohr: 170 values will be 16 pages
04:50 PM rue_mohr: so the empty book is almost $16 of that $18
04:50 PM rue_mohr: er, plus $6 shipping
04:50 PM polprog: hmm
04:57 PM polprog: ill see
04:59 PM Tom_L: what target mcu did you get?
04:59 PM polprog: i think the 1st one off the list
05:00 PM polprog: i suspect the key is the same
05:00 PM polprog: unless they cookied me
05:00 PM Tom_L: what's the difference between them?
05:00 PM polprog: no idea
05:00 PM Tom_L: keil tools typically are not free
05:00 PM polprog: i picked one that had 80c51 in its name
05:01 PM rue_mohr: https://www.aliexpress.com/item/32370322093.html is like https://www.aliexpress.com/item/1827331562.html plus https://www.aliexpress.com/item/32752639161.html
05:01 PM polprog: ill try to install the targz tomorrow..
05:02 PM Tom_L: did you get one rue_mohr ?
05:03 PM rue_mohr: a book like that?
05:03 PM rue_mohr: I got pages, and a book locally
05:03 PM Tom_L: 7051
05:03 PM Tom_L: 8061
05:03 PM Tom_L: 8051
05:03 PM rue_mohr: hah, its just software.
05:03 PM Tom_L: skip that
05:03 PM rue_mohr: its a 8051 software package
05:03 PM Tom_L: maybe if they were offering free xilinx chips
05:03 PM rue_mohr: from what I can tell, there is no hardware to the giveaway
05:04 PM rue_mohr: and its 8051
05:04 PM rue_mohr: have you ever tried to operate an 8051 io port?
05:04 PM Tom_L: the combined book price looks like they took the price of one and subtracted it from the price of the other and give you the combined product for less
05:05 PM rue_mohr: yup
05:05 PM rue_mohr: they get a subsidy for an assembly factory
05:05 PM Tom_L: i got a bag o resistors a long time ago
05:06 PM Tom_L: no clue where they are now
05:06 PM rue_mohr: I have an 8.5"x11" binder I use for parts
05:06 PM rue_mohr: but its got 35mm film holders, so I have 3 values ea stuffed into each slot
05:06 PM polprog: im going through my smd box...found some eerams. neato
05:09 PM rue_shop5: I'm using 17 pages currently
05:10 PM rue_shop5: but each page I'm using holds 21 values
05:10 PM rue_shop5: so technically I'm about 34 pages of a normal book
05:11 PM rue_shop5: I'm tempted to buy the 100 pages
05:12 PM rue_shop5: if anything I'd probably shim the supply of 0603 resistors
05:13 PM polprog: im tempted to order the *22093, book w/ parts kit
05:15 PM polprog: nn
05:16 PM Tom_L: rue_shop5, haven't you collected enough yet? you should start using some
05:17 PM rue_shop5: but the price...
05:17 PM rue_shop5: :)
05:17 PM Tom_L: the price is the loss of space
05:17 PM rue_shop5: ok, for the filter profiler, I need to work out a "value has settled within 1% ove rhte last 200ms" code
05:18 PM Tom_L: no 'good' mail today
05:19 PM rue_shop2: I keep thinking we are over freezing, but the line I'm looking at is -5c
05:20 PM polprog: rue_shop2: compare output of integrator and differentiatior?
05:20 PM rue_shop2: oh software
05:21 PM polprog: well
05:21 PM polprog: its possible in software
05:21 PM polprog: compare average with min/max maybe
05:21 PM rue_shop2: I'll check the last reading against a 1% range of the last reading
05:21 PM polprog: goodnight again...
05:21 PM rue_shop2: hah
05:21 PM rue_shop2: you all start waking up just after I'm supposed to have gone to bed
05:22 PM rue_shop2: keep me up all night
05:22 PM rue_shop2: 800-some-odd followers I'm seeing a pattern
05:22 PM rue_shop2: really wonder how many are bots...
05:23 PM rue_shop2: random tests show most are real
05:29 PM rue_shop2: } while( (Duty1 < 0x7E) || (Duty1 > 0x82) || (Duty2 < 0x7E) || (Duty2 > 0x82) );
05:29 PM rue_shop2: thats what I have so far
05:30 PM rue_shop2: 0x80 is 50% duty
05:30 PM rue_shop2: but the values dont always settle on 50%
07:09 PM Marl000: MoonyMoons son here
07:11 PM rue_shop5: 4.986V, 0.028V, 4.956V, -0.057V, 4.9Hz, 4.9Hz, -2 deg, -2 deg

07:11 PM rue_shop5: hi
07:13 PM Marl000: yo
07:22 PM Tom_L: rue_shop5, you gettin it to work?
07:22 PM Tom_L: is that your phase stuff?
07:24 PM rue_mohr: yes, but
07:24 PM rue_mohr: thats an RC filter
07:24 PM rue_mohr: -106 degrees?
07:24 PM rue_mohr: its about 16 degrees over what should be possible
11:04 PM zhanx: E
11:04 PM zhanx: vning
