01:03:45 <motosteve> Hi
01:04:04 <Kuschelpony> and hello Steve
01:07:11 <Kuschelpony> question to the chatroom, has anyone asuggestion for a well available single or dual opamp for 5V supply, input common mode range includes these 5V, offset less than 1mV, output almost rail to rail ?
01:07:32 <Kuschelpony> its for a low-drop shunt in an USB supply

02:06:39 <MrMobodies> How do they know "criminal networks" are involved
02:07:18 <MrMobodies> I suppose what they are doing could be as criminal in watching without paying
02:11:45 <MrMobodies> "£50,000 and up to 12 months in prison"... with the recent changes made to to bloating of the Amazon Prime video since I stopped using it, such as the search page (dorced onto that what use to be video explorer), removal of date filters, difficulty getting to other filters buried away and annoying tiles that popout and annoy, lack of details on these tiles, I'd say it's not worth paying any
02:11:45 <MrMobodies> attention to.
02:13:35 <MrMobodies> Very disappointed how they buggered up and made the UI horrible for me to use and I am surprised piracy went up so much they needed to directly tackle those using it.
02:15:30 <MrMobodies> I suppose what maybe going for them is no channel logo stuck over the top left corner.
02:38:40 <arch> Kuschelpony, DHess_US, good news and bad news. good news, i got that generator outputting voltage and the governor linkage was adjusted to output ~3600rpm. initially it was waaay overrevving because some moron must have been fiddling around without knowing what they were doing. bad news is, the chinese carburetor i put in has a leaky needle and seat, so it leaks fuel out the intake. as a short term mitigation, i am using the
02:38:41 <arch> fuel shutoff. im going to order legit Stens aftermarket needle and seat assembly to fix that china carb,
02:39:10 <Kuschelpony> at least good progress
02:39:24 <arch> it is outputting 127VAC at 61Hz. i can tweak it down ever so slightly, but i think a bit higher voltage is fine due to voltage drop from the 25 ft L14-30R cord
02:40:34 <Kuschelpony> the voltage might change more than proportional with frequency, so get it to 60Hz first, and then see if its still considerably over 120
02:40:36 <Kuschelpony> V
02:41:20 <arch> the good thing about this generator--absolutely no computers involved. it's just a synchronous generator, with brushes, field winding, and i think adjustable resistor, and that's it. here is the schematic for it: https://i.imgur.com/S0Q4vCp.png
02:42:32 <arch> weeee!
02:43:56 <arch> i wish it was quieter, but these old tecumseh engines rarely are. but, they run on and on and on, no problems. and it seems this engine was not abused, other than nobody adjusting the valve clearances
02:45:38 * arch gets destroyed by centrifugal forces: https://youtu.be/qEkeIDFfq_8&t=120
02:46:52 <Kuschelpony> ok, no way to regulate the voltage at all, its just a dynamo runningup until the rotating iron is deep in saturation
02:47:36 <Kuschelpony> thats one of the situationswhere my comment about rotation speed applies
02:48:39 <Kuschelpony> mrmobodies, photos show how crazy careless people were, holding up fireworks and not even immediately leavin the room when the ceiling started burning
02:49:00 <Kuschelpony> i miss the time when it was a joke to say "Leave the burning building before you tweet about it"
02:52:34 <arch> Kuschelpony, the only way to regulate the voltage is adjust the RPM of the engine. that affects frequency as well though.
02:52:46 <Kuschelpony> thats what i tried to say
02:53:03 <Kuschelpony> voltage is likely to change more than proportional to RPM&Frequency
02:54:18 <arch> hm, but now you made me curious. what happens if i DID overload that generator's output winding? i assume the voltage would crash and/or coils would start smoking. i don't see any protection means for the 3-pin connector between the two power windings
02:54:55 <arch> let's assume my engine is strong enough to overpower anything and the generator's rotor continues spinning
02:55:21 <DHess_US> arch, you don't think removing the needle and seat (for the float?) and cleaning them would fix it?
02:55:23 <Kuschelpony> it has no compounding, so voltage will sag and on some amount of overload fall down to almost zero
02:55:52 <Kuschelpony> not sure if this happens at currents that are above or beow where the wire burns off
02:56:32 <Kuschelpony> on a short, it will run almost without load on the combustion engine
02:56:53 <arch> DHess_US, this is a brand new aftermarket carburetor, and its needle/seat is faulty. so i would have to replace them. OR...since i also have the OEM carb, i think i will just get the OEM tecumseh carb rebuild kit and put the OEM rebuilt carb back on. it really is true..it's a crapshoot what you;ll get with aftermarket chinese carbs...most do work fine, then you get a few lemons...
02:57:49 <DHess_US> arch, might have been just assembled wrong, but I would pull the seat and at least look at it.
02:58:07 <DHess_US> Maybe they left the seat out.
02:59:17 <arch> possible. i mean, for all we know, they could have some poor kids in chinese sweatshops assembling these by hand. easy to miss out on teeeeeny tiny parts
03:03:02 <Kuschelpony> looks like there is nowhere on the internet of today an article about dc dynamos anymore https://en.wikipedia.org/wiki/Shunt_generator
03:03:03 <EEVBot> Unexpected JSONDecodeError (Expecting value: line 1 column 1 (char 0)) from Kuschelpony. Message was: https://en.wikipedia.org/wiki/Shunt_generator
03:06:04 <arch> thanks for that link Kuschelpony. good stuff to research while the work load is light. nobody's back to work yet at my workplace lol
03:07:02 <Kuschelpony> im still trying to find articles about a serious self-regulating alternator-dynamo, they were already well developed in 1960
03:09:09 <arch> hmm, so i wonder. what would happen if (looking at the schematic), rather than the field winding getting fed with rectified but unfiltered DC, if you put a capacitor so that the field is fed with relatively pure DC? would it "help" the output be more stable under load?
03:09:41 <Kuschelpony> no, the rotating winding has already so much inductivity that there is almost pure DC current flowing
03:09:48 <arch> ah
03:10:59 <Kuschelpony> what you would need is at least a current transformer that samples the output current and adds it (with the right phase shift) to the AC voltage going into the rectifier
03:11:16 <arch> im gonna see if i can find more of these oldie generators at auction. they hardly go for much money, and being pretty foolproof, i think it might be nice to have some. i can give them away to family after fixing up
03:11:37 <Kuschelpony> that way the magnetization gets a boost with load, more boost with inductive load and perhaps a buck with capacitive load to compensate resonance effects)
03:12:38 <Kuschelpony> also the rotating part would need a cut of specific width in the iron, that part of the iron goes early in saturation to create a base voltage, and the other part adds the right boost at increased magnetization
03:13:22 <arch> you've lost me now lol, but it's pretty damn cool to have that knowledge
03:14:10 <Kuschelpony> oops well its truly a bit convoluted but ingenious how to make a alternator-dynamo that self-regulates its voltage
03:15:35 <Kuschelpony> seems that knowledge has entirely disappeared from the internet
03:17:14 <arch> this is why we need pirates (information collecting kind). like me, i always download a local copy of youtube technical vids, locally dump websites with wget, safe pdfs, etc
03:17:28 <arch> save pdfs*
03:17:54 <arch> hell, even archive.org is no longer safe
03:18:20 <arch> we need archive.org to be archived...by another archiving site
03:19:21 <arch> it will only get worse with AI because google and all these other sites will "summarize" all the indexed sites, and most people are lazy, so over time that knowledge of technical sites that look like they came straight out of the 90s...will be gone for good

17:06:50 <MrMobodies> Just had a look at Plane9 V2.5.1 for the animations
17:07:10 <MrMobodies> they were nice but one thing, only lousy thing they did ruined many of them
17:07:20 <MrMobodies> they put this stupid GLARE over them
17:08:25 <MrMobodies> damn can't seem to print screen
17:08:32 <MrMobodies> it is in Opengl though
17:08:48 <MrMobodies> some great effects, but the glare makes them unclear

17:13:40 <MrMobodies> Got that from Archive.org a 2011 copy
17:13:51 <MrMobodies> and wow it looks so much better and no stupid GLARE/BLUR yet
17:14:26 <MrMobodies> and I could edit the animations whereas the other I couldn't

17:15:39 <MrMobodies> Now THAT would be PERFECT for my disco later today
17:16:35 <MrMobodies> not as fancy as that newer version but more in keeping and not too flashy or the artificial glare
17:17:07 <MrMobodies> I see there are ones I can't open, Supporter and they want a donation
17:17:27 <MrMobodies> Shareware in the nicest possible way
17:17:40 <MrMobodies> I'll see later if they could give me the key for this older version
17:20:21 <MrMobodies> I also like the fact I can not only edit but delete all the stuff I don't want.
17:21:33 <MrMobodies> Yep the older one is better than the newer one

17:23:59 <MrMobodies> Some great stuff, but no way to adjust, remove glare or add or change colours
17:24:15 <MrMobodies> to make it in keeping
17:25:41 <MrMobodies> I think what could have happened, they switched from studio to a newer or a different backend, struggled where they spent all their energy.

23:51:35 <MrMobodies> and that Evenghost that I use to control them I didn't know it had so much of functionality.
23:51:35 <MrMobodies> I found Eventghost supported this too and found one on Ebay for £20,

23:51:35 <MrMobodies> It'd be nice if I could find a way of bypassing the infrared input of the Marmitek transceiver and wire it up directly.
23:51:35 <MrMobodies> I found in Eventghost plugins a "Network event sender" and receiver, something that'd be very handy, to trigger events from a webpage on a tablet and start things.
23:51:35 <MrMobodies> Especially a button square on a tablet to remote start a player with birthday tune on the laptop without having to always find it.

23:51:35 <Ampera> I wonder if it's possible to run a CPU's clock off a microphone
23:51:35 <Ampera> I don't have a practical reason for this
23:51:35 <Ampera> but it would be funny to have a CPU you have to yell at in order to make it do math
23:51:35 <Ampera> and the higher you yell at it, the faster it maths
23:51:35 <rc-garage> aaaah, this makes me think of making plans, and women yelling for no reason...
23:51:35 <rc-garage> maybe there is a reason
