12:10 AM rue_mohr: polprog, I see an SCR flasher circuit, but its not as good as ours
05:51 AM polprog: rue_mohr: hmm, link?
06:10 AM rue_mohr: I'm going thru pdf books
06:10 AM rue_mohr: Encyclopedia of electronic circuits volume *
06:29 AM polprog: https://www.zpag.net/Electroniques/Kit/Graf_-_Encyclopedia_of_Electronic_Circuits_-_Vol_5.pdf ?
06:29 AM polprog: i like how it has two adverts for syrian electronic component shops stiched in
06:32 AM rue_mohr: and 4, I have 3 as a real book, I found 2, I bought 1 and 2
06:32 AM polprog: thats a nice book
06:33 AM polprog: ill wget all 5 parts
06:33 AM polprog: i got sent an electronics book by a friend, discarded from his uni library
06:33 AM rue_mohr: I dont think 1 is available
06:33 AM polprog: it has no front cover, so i dont know the title..
06:33 AM polprog: https://www.zpag.net/Electroniques/Kit/Graf_-_Encyclopedia_of_Electronic_Circuits_-_Vol_1.pdf
06:33 AM polprog: i jsut changed the number in the url
06:33 AM rue_mohr: I want them on paper, its handy when you need to correct the errors
06:33 AM polprog: yeah, paper is nice
06:34 AM rue_mohr: huh, why didn't that work for me
06:35 AM polprog: >Site en développement
06:35 AM polprog: >Depuis Janvier 2005
06:35 AM rue_mohr: have a laugh when you get to vol 5, page (real page, not pdf page) 302
06:36 AM rue_mohr: I swear a lot of these circuits are designed to use as many parts as they can
06:37 AM polprog: i see a light meter and a mercury switch
06:37 AM rue_mohr: yea, the mercury switch
06:37 AM rue_mohr: I bet you can find a way to reduce the parts count :)
06:37 AM polprog: its a bit superflouous :D
06:38 AM rue_mohr: ;)
06:38 AM polprog: and there is no debouncing ! (do these need debouncing actually :D)
06:38 AM rue_mohr: its a lot of sillyness and a bit of gold
06:38 AM polprog: yep, as usual in these books
06:38 AM rue_mohr: I dont think mercury switches actually have bounce
06:39 AM rue_mohr: cause of the surface tension of the mercury
06:39 AM polprog: i like how each circuit is drawin with a differetn line style
06:40 AM polprog: and it just says "popular electronics" "303 circuits" "radio electronics"
06:40 AM rue_mohr: they are collected, most from datasheets
06:40 AM polprog: yeah. useful to have them in one place
06:40 AM rue_mohr: lots from magazines too
06:40 AM rue_mohr: they list the actual articles in the back
06:41 AM polprog: i actually found an auction for UM9151
06:41 AM polprog: dialer
06:41 AM polprog: oh, its a ctually a pulse dialer wtf
06:42 AM polprog: why do you need an IC for that
06:42 AM rue_mohr: heh
06:42 AM polprog: must be pre MCU era
06:42 AM polprog: i was thinking about buying some but i thought this was DTMF
06:42 AM rue_mohr: Popular electronics keeps thinking the 2N4403 is an NPN
06:42 AM polprog: today in polprog's computer heresy blog: high speed data links using DTMF dialers
06:42 AM rue_mohr: be aware there are LOTs of mistakes in these
06:52 AM polprog: i should actually measure the dark current of that phototransistor
06:52 AM polprog: or currents in general
06:53 AM polprog: that was pretty much what my initial detector was doing (1M in paralell + voltage follower)
06:56 AM rue_mohr: vol 5, 55-39 nice.
06:56 AM rue_mohr: but, wtf, use a 7414 already
08:25 AM polprog: https://i.ibb.co/h1f9n4D/IMG-0332.jpg
08:35 AM rue_bed: floppy on phone!?
08:36 AM polprog: it's a USB mass storage device after all
08:36 AM polprog: attahches as /dev/sdc on my system
08:38 AM polprog: what do you mean 7414
10:31 AM rue_mohr: 74xx14 ttl
11:01 AM moon_: :)
11:01 AM moon_ is now known as MoonyMoon
11:02 AM rue_bed: there ya are
11:02 AM rue_bed: https://www.zpag.net/Electroniques/Kit/Graf_-_Encyclopedia_of_Electronic_Circuits_-_Vol_1.pdf
11:02 AM rue_bed: I havn't done that one yet
11:05 AM MoonyMoon: done?
11:06 AM MoonyMoon: looked at, or printed ("done that one")
11:11 AM rue_bed: looked thru
11:11 AM rue_bed: their large
11:11 AM rue_bed: just going thru it now
11:12 AM * Tom_L wipes the jelly off his face
11:13 AM ShopMoon: here I am now
11:13 AM rue_bed: did you open it up?
11:14 AM Tom_L: here i was then and now
11:14 AM ShopMoon: yes
11:14 AM ShopMoon: 1938
11:14 AM rue_bed: I found a few good ones in the other books last night
11:14 AM rue_bed: maybe something to use for my filter profiler
11:15 AM ShopMoon: oh yeah
11:15 AM ShopMoon: I'm just all about chicken wings this morning
11:15 AM rue_bed: and an oscillator to try
11:15 AM ShopMoon: im into new oscilators :)
11:17 AM Tom_L: so are you working or have they furloughed you yet?
11:17 AM ShopMoon: Im working
11:17 AM ShopMoon: Just because of this shit
11:19 AM Tom_L: Ca kids on spring break in Fl seem to have brought it home
11:19 AM ShopMoon: :(
11:22 AM Tom_L: bad page on P254 / 246
11:22 AM rue_bed: heh, not there yet
11:23 AM rue_bed: did they dot everything? :)
11:23 AM Tom_L: smeared
11:23 AM Tom_L: bad scan or something
11:45 AM ShopMoon: MiniBat: Who are you?
11:46 AM ShopMoon: MarMar?
11:47 AM ShopMoon: I know its you I see your user&IP
11:47 AM Tom_L: Real Name: Durp Stick Child
11:47 AM ShopMoon: yeah thats one of my kids XD
11:49 AM ShopMoon: MiniBat: well say hello already
11:49 AM ShopMoon: are have you already forgotten you opened this window?
11:51 AM ShopMoon: or* fuck im stupid
11:57 AM polprog: evening
11:57 AM polprog: hello ShopMoon ;)
11:58 AM polprog: rue_bed: im thinking whether to check if the other photointerruptor (the wide one that i have 1 pc) works better
11:58 AM polprog: wht the heck is wrong with that photointerruptor
12:09 PM ShopMoon: polprog: Hey dude :)
12:16 PM MiniBat: hey Guys
12:17 PM Tom_L: damn, it is a real nick
12:20 PM ShopMoon: MiniBat: done breakfast?
12:22 PM ShopMoon: I'm going to hit the can for a bit MiniBat, why dont you ask these guys the difeerance between ISA PCI, and PCI Express
01:06 PM polprog: between ISA, PCI, PCI Express and PCI compliance
01:17 PM rue_mohr: polprog, the 2+3 pin ones are logic
01:17 PM rue_mohr: aka, the 3 pins are +5V, GND, and an open collector ouput
01:17 PM rue_mohr: I dont know in what order
01:17 PM rue_mohr: I love them casue you dont have to deal with all the phototransistor junk
01:18 PM polprog: good
01:18 PM polprog: i have two narrow and one wide
01:18 PM polprog: i could cut the wide one and repurpose it for a reflective one
01:19 PM rue_mohr: I'm not sure how I work out the pinout
01:19 PM rue_mohr: lots of times I have the pcb, and can work it out from the common ground trace and the decoupling cap
01:20 PM polprog: i still have the PCB for these
01:20 PM polprog: so ill take a look at them
01:20 PM rue_mohr: it might even say on the silkscreen
01:59 PM polprog: theres a line driver on the PCB so that should be pretty obvious
02:35 PM rue_mohr: vol 4 Fig 34-2 !!!! THATS A GOOD CHART!!!!
02:36 PM Tom_L: rue_mohr, you workin this week?
02:36 PM rue_mohr: I called in today, I need to have the stuff attacking me settle so I know wtf
02:37 PM Tom_L: they've shut down a few more places in the US
02:37 PM Tom_L: NY for one
02:37 PM rue_mohr: I was being worked over by something before this all started
02:37 PM Tom_L: i got a few but some have backed out
02:37 PM rue_mohr: and I dont know if I'm being paranoid or not, but I swear the symptoms changed a few days ago
02:38 PM rue_mohr: A TEST WOULD BE NICE
02:38 PM Tom_L: alot of service ppl here are wearing gloves now
02:38 PM rue_mohr: their only testing hospital staff and people related to outbreaks
02:38 PM Tom_L: tests are scarce
02:39 PM rue_mohr: there are kits from china, but
02:39 PM rue_mohr: 2 months later I'll know anyhow
02:39 PM Tom_L: there are fake kits too
02:39 PM rue_mohr: yea
02:39 PM rue_mohr: think they do the responcible thing and say +?
02:41 PM Tom_L: doubtful
02:44 PM rue_mohr: vol 4, Fig 36-1, they could have used the 324 as the amp, schmitt, and latch
02:46 PM rue_mohr: there are other issues with that circuit too, like its isolation...
02:51 PM rue_mohr: vol 4, Fig 37-1 CD4066 based oscillator!!!!!
02:51 PM rue_mohr: THATS COOL
02:55 PM polprog: oh my
02:55 PM polprog: these books arent OCR'd
02:55 PM rue_mohr: na
02:55 PM polprog: rue_mohr: i figured out the pinouts of the interruptors
02:56 PM rue_mohr: good
02:56 PM rue_mohr: they might need an output pullup
02:56 PM rue_mohr: usualy do
02:56 PM rue_mohr: the logic ones are nice cause they just output a nice clean signal
02:57 PM polprog: woow thats a great chart
02:57 PM rue_mohr: I beleive I was going to make something like it years ago
02:57 PM rue_mohr: but its definitly better
02:57 PM rue_mohr: MoonyMoon, what do you think!?
03:00 PM MoonyMoon: WHOAh
03:00 PM MoonyMoon: leme catch up
03:00 PM rue_mohr: MoonyMoon, vol 4, fig 38-3 its a good lookin radio circuit
03:04 PM MoonyMoon: wireless ir
03:04 PM MoonyMoon: thing
03:04 PM MoonyMoon: ?
03:04 PM MoonyMoon: im looking
03:04 PM rue_mohr: your on volume 4 then, right?
03:05 PM MoonyMoon: yeah
03:05 PM rue_mohr: its a securrity system, but its got those circuits in it for RF
03:05 PM MoonyMoon: is the "tank" T1 and c8
03:05 PM MoonyMoon: ?
03:06 PM rue_mohr: yes
03:06 PM MoonyMoon: see its got that happy CAP across the emitter to collector there
03:06 PM polprog: 63-8 vol 4 is cool
03:06 PM rue_mohr: (sorry had to scroll back, I'm already on page 251
03:06 PM rue_mohr: )
03:07 PM rue_mohr: not sure on that one polprog, I'd try it
03:07 PM polprog: same
03:08 PM polprog: i printed that potentiometers chart
03:08 PM rue_mohr: :)
03:10 PM MoonyMoon: see now im a simple man, 38-12 looks cool
03:10 PM polprog: haha
03:11 PM MoonyMoon: yeah :/
03:11 PM rue_mohr: :)
03:11 PM polprog: you migh tlike this then: https://polprog.net/rozne1/ircjunk/thyrosc2/power_thyrosc_build.png
03:11 PM polprog: 5 parts
03:11 PM MoonyMoon: ill look
03:12 PM polprog: rue_mohr: i found my old robot kit and two bare phototransistors in it
03:12 PM rue_mohr: yep
03:13 PM rue_mohr: how about using leds as photodiodes?
03:13 PM polprog: i was thinking about that
03:13 PM MoonyMoon: Im too simple for that
03:13 PM rue_mohr: I havn't seen it yet in these books
03:13 PM MoonyMoon: polprog: what is that you have in that pic?
03:13 PM polprog: MoonyMoon: a power thyristor based relaxation osc
03:14 PM polprog: me and rue were playing with SCRs for a good week recently :D
03:14 PM rue_mohr: Moon has his own osc
03:14 PM rue_mohr: using a backwards PN2222
03:14 PM MoonyMoon: not mine exactly
03:14 PM polprog: hmm, tell me more
03:14 PM rue_mohr: you discovered it on the internet :)
03:14 PM MoonyMoon: :P
03:16 PM polprog: would any of you want these OCR'd?
03:16 PM rue_mohr: hahaha vol 4, figure 46-15
03:16 PM rue_mohr: measure capacitors by how many flashes, at 1 flash/second 1 flash = 1uF
03:16 PM polprog: haha
03:17 PM * rue_mohr puts 1000uF cap down on the bench
03:17 PM polprog: aka the epilepsy detector
03:17 PM * polprog hooks up a Nikon flash module to the output
03:17 PM rue_mohr: (to be fair, they have a scale setting for it, but, yea, heh)
03:19 PM polprog: 2-1 is pretty crazy as well
03:19 PM polprog: also lol, they give the code listing as a direction to a BBS
03:19 PM rue_mohr: :)
03:20 PM polprog: 5-6, "analog" delay line with a 512 stage shift reg
03:21 PM polprog: i didnt know they made analog shift regs :D
03:21 PM rue_mohr: :)
03:22 PM rue_mohr: there was one yesterday that used two 8748 microprocessors with a note about code from one of the magazine printers
03:24 PM polprog: two?
03:24 PM polprog: SMP?
03:24 PM rue_mohr: RX - TX iirc
03:24 PM rue_mohr: if your going thru them, you will see it
03:24 PM rue_mohr: they use an external memory chip with them, looks like another sales pitch
03:26 PM polprog: 20-11 HAHAHAHAHAH
03:27 PM rue_mohr: :)
03:27 PM rue_mohr: yea, saw that last night :)
03:27 PM polprog: i mean.. if its good for ICBMs it's good for your computer
03:33 PM rue_mohr: ooo V4 Fig 49-5
03:33 PM rue_mohr: 49-8, sonar, cool
03:34 PM polprog: neat
03:34 PM polprog: i could use that... in the barge project
03:35 PM rue_mohr: my filter profiler is more complex
03:35 PM rue_mohr: it tells you signal offset, and phase info
03:35 PM polprog: nice
03:35 PM polprog: i dont think 49-9 would work fine
03:35 PM polprog: i dont see a bandpass for the sonar frequency
03:35 PM rue_mohr: ah good point
03:36 PM rue_mohr: lots of these have errors that can be hard to notice
03:36 PM polprog: i wonder if i could make some simple DSP on the STM32 to use it as a sonar..
03:36 PM rue_mohr: hahah 52-8, they dont just pull the triangle off the cap of their oscillator!
03:37 PM rue_mohr: ooo fpga...
03:37 PM rue_mohr: digital filter?
03:37 PM polprog: what fpga?
03:37 PM polprog: yeah 52-8 could be way simpler
03:38 PM rue_mohr: any fpga
03:38 PM rue_mohr: it could generate the chirp, filter the input, and time the difference
03:38 PM polprog: i did a PWM in a way simpler way when i was doing the inital 15VDC supply for the VFDs
03:38 PM polprog: oh yeah it could
03:38 PM rue_mohr: those go up to 400Mhz ya know
03:38 PM polprog: ideally youd have several chirps to rule out any false positives
03:42 PM rue_mohr: I dont like intelligent things operating power supplies, they screw up
03:42 PM polprog: it could generate a sweep even
03:42 PM polprog: that way you have a nearly continous measurement
03:42 PM polprog: hmm, yeah. sweep, then feed the TX and RX into a heterodyne, filter out the upper freq and you have a frequency dependent on the distance
03:42 PM polprog: in theory
03:42 PM polprog: in practice that wouldnt work all that well... unless with a directional mic
03:44 PM polprog: i was thinking about this, to just blink the led and detect change in phototransistor current
03:44 PM polprog: small change = black; big change = white
03:44 PM polprog: but i could also just AC couple the signal
03:44 PM polprog: to a hct14
03:46 PM rue_mohr: maybe
03:46 PM rue_mohr: ooo, my new favorite unobtainable chip: 27SL19
03:47 PM polprog: i cant even find the datasheet...
03:48 PM rue_mohr: 8*32 prom
03:48 PM polprog: whats so special about it
03:48 PM polprog: oh wai 8*32 not 32*8
03:48 PM rue_mohr: oh, huh, yea, my normal sources say no datasheet
03:48 PM polprog: nice
03:49 PM rue_mohr: yea, small, but usefull as a logic block
03:49 PM * polprog gives rue 4 32*8 eproms and some super glue
03:49 PM rue_mohr: oh MoonyMoon there is a circuit in one of these books for a 2400 baud casette tape interface
03:49 PM rue_mohr: er, not 32k
03:49 PM rue_mohr: 32
03:50 PM rue_mohr: dont think they made 8*32 eeproms
03:50 PM rue_mohr: that one was just prom, supposedly
03:52 PM rue_mohr: 58-7 is a cute idea to get an op-amps output to the rails
03:52 PM rue_mohr: easier with a schmitt buffer tho
03:53 PM rue_mohr: haha, 59-1
03:53 PM rue_mohr: pll for an opto interrupter
03:54 PM polprog: 47-5 vol 6
03:55 PM rue_mohr: 6!?
03:55 PM rue_mohr: did I know there was a 6...?
03:55 PM polprog: i linked it
03:55 PM polprog: an ho
03:55 PM polprog: well, its in the same place, just change 4 to 6
03:55 PM rue_mohr: I closed some
03:55 PM rue_mohr: I been going out of order
03:56 PM rue_mohr: if ls -lrt is the last modifed time, when is the creation time?
03:58 PM rue_mohr: https://www.zpag.net/Electroniques/Kit/Graf_-_Encyclopedia_of_Electronic_Circuits_-_Vol_6.pdf
03:59 PM polprog: not sure, but stat(1) will tell it in a more friendly format
03:59 PM rue_mohr: hmm
03:59 PM rue_mohr: great, now I have another book I have to go thru
04:00 PM rue_mohr: another 24M for the fileserver...
04:03 PM polprog: if you are rehosting it i could run ocr for you
04:08 PM rue_mohr: dont need ocr, I need a paper copy I can scribble the corrections on
04:10 PM polprog: ah
04:11 PM rue_mohr: oh!
04:11 PM rue_mohr: hello
04:11 PM rue_mohr: V4 fig 60-7
04:11 PM rue_mohr: scr oscillator
04:12 PM rue_mohr: I have that in volume 3 too
04:16 PM rue_mohr: oh wow, V4 fig 62-3, they use the reflection impedence to know if it tripped
04:37 PM rue_mohr: MoonyMoon,
04:37 PM rue_mohr: V4, fig 71-9 (pdf page 467)
04:38 PM rue_mohr: the same tank can be used in a transmitter
04:43 PM polprog: a differen scr oscillator design
04:54 PM rue_mohr: V4, fig 88-6 (pdf page 584) thats a chopper amplifer (with a error in the way the switch is done)
04:58 PM polprog: still browsing vol4? wow
04:59 PM rue_mohr: I'm too tired to do much else
04:59 PM rue_mohr: I havn't fallen asleep on the down key tho
04:59 PM polprog: same, i drew a draft of the sharp optocoupler (just to test myself) and suddenly i lost all desire to sit to that tonight
05:01 PM rue_mohr: I have about 10 circuits redrawn on a sheet of paper to maybe try tonight
05:03 PM polprog: i drafted a silly hct14 signal level indicator
05:03 PM polprog: i have this idea
05:03 PM polprog: make as much weird circuits with the humble hct14
05:03 PM rue_mohr: :)
05:03 PM rue_mohr: remember my RS latch
05:04 PM rue_mohr: and toggle FF
05:04 PM polprog: yep. i still need to build it and probe it
05:04 PM polprog: what toggle ff?
05:04 PM polprog: bbl, make supper
05:06 PM rue_mohr: MoonyMoon, V4 figure 103-1 pdf page 665
05:11 PM rue_mohr: ok, thats volume 4, I need rest!
06:39 PM rue_mohr: MoonyMoon, I have one of those power bars left, but I wanted one for the electronics bench yet
06:40 PM rue_mohr: I kinda underwired that front wall, there are only 2 recepticles on it, I have 3 filled power bars
06:41 PM Tom_L: call an electician to add more outlets :)
06:42 PM Tom_L: i'll sure be glad to get back to work...
06:42 PM Tom_L: goin stir crazy
06:43 PM rue_mohr: they are sayin sept for things to get back to normal
06:43 PM rue_mohr: :S
06:44 PM Tom_L: i've got a couple calls tomorrow
06:44 PM Tom_L: one backed out
06:44 PM rue_mohr: I been feelin ill for a while, I was just pushing thru
06:44 PM Tom_L: goin out in full hazmat suit...
06:44 PM rue_mohr: the symptoms shifted a bit and I'm not so sure I want to be clumbsy
06:44 PM Tom_L: fever?
06:45 PM rue_mohr: no, chills, rough throat, has some headaches
06:45 PM rue_mohr: I think the rough throat is the polen mostly
06:45 PM Tom_L: probably
06:45 PM rue_mohr: but, pondering it, whatever I do have, if not it, is going to make me more suseptable to anything
06:46 PM Tom_L: yup
06:46 PM rue_mohr: if I do have it there is no way to know, or find out
06:46 PM rue_mohr: and I'd just mess a bunch of other people up
06:47 PM rue_mohr: the big test is, can you hold your breath for 10 seconds
06:47 PM rue_mohr: if you cant, you got an issue
06:48 PM Tom_L: funny, when a kid i could hold it for 2-3 min
06:48 PM Tom_L: not anymore
06:48 PM rue_mohr: wait till I'm a robot, then I can work on setting a record
06:48 PM rue_mohr: wait, you have to finish to set... ugh, whatever
06:49 PM rue_mohr: dynamic record?
06:49 PM rue_mohr: I'm gonna build an antiviral helmet for the thing that comes out 4 years from now
06:50 PM Tom_L: by then you'll need more than that
06:50 PM Tom_L: did you see the stuff the italians are using?
06:51 PM rue_mohr: ? maybe not
06:53 PM Tom_L: can't find a pic..
06:55 PM Tom_L: https://www.dailymail.co.uk/news/article-8134247/Bubble-helmets-used-Italian-doctors-boost-survival-rates.html
06:55 PM Tom_L: video on right
06:55 PM Tom_L: https://www.dailymail.co.uk/news/article-8134247/Bubble-helmets-used-Italian-doctors-boost-survival-rates.html
07:01 PM rue_mohr: cool
07:11 PM rue_mohr: volume 6, 29-3 pdf page 210 is notable, as it looks like its got some good tricks to get around isues with the 555
07:11 PM rue_mohr: or they have pins 2 and 3 mixed up
