02:51:42 <rc-garage> what is your thing about "spin" ? you really like whatever spin things?
03:33:54 * arch shows off his fidget spinner collection to rc-garage and T3sl4; electrohead is excluded because fuck him
03:34:03 <arch> :p
03:34:23 <rc-garage> I somehow do not doubt you have that
03:35:15 <arch> quick question, i think. is it a good idea to charge lifepo4 batteries at 1C charge rate? the battery case recommends a max charge rate of 0.5C, for a 12V 20Ah battery
03:38:43 <arch> jeeeezus... $128 for this excitation capacitor... https://shop.briggsandstratton.com/products/briggs-and-stratton-312699gs-capacitor
03:38:43 <EEVBot> [url] Briggs & Stratton 312699GS Capacitor - Qty 1 = (2) Capacitors 35uF - Briggs & Stratton Online Store | shop.briggsandstratton.com
03:39:12 <arch> then again... Ducati...
03:45:58 <electrohead> ok then
03:46:15 * electrohead bops arch on the noggin with a modified atari 800
03:47:34 <arch> aha, this seems to be applicable for ye olde' generator: https://www.semanticscholar.org/paper/Evaluation-of-excitation-capacitance-for-a-two-self-Khan-Khan/5bce42d6f9c0e97653b114f0e971be802f85ca49
03:48:18 <arch> "This paper presents a detailed steady state modeling and analysis of a single phase, two winding SEIG to evaluate its optimum excitation capacitance for resistive as well as inductive static loads."
03:50:07 <arch> so it would seem if i pick too large a capacitor, i could get more power out of the generator, as long as the engine HP can handle the extra load. but it might burn out the windings of the genny i think :D so i think i will pick middle ground and go ahead and order a 35uF 450VAC capacitor
03:56:02 <rc-garage> yaay! so that is done
03:59:32 <arch> yep. now i dont have to maim myself juryrigging a lower voltage ac capacitor and it exploding
04:00:21 <arch> even if i put the two herm-c-fan caps in series, no guarantees the voltage sharing will be decent. capacitance values are different too.
05:03:33 <rc-garage> make a video!
05:03:52 <rc-garage> it has been a while, since i saw anything interesting on ogrish.com

08:02:42 <flyback> yeah
08:02:45 <flyback> it's all about balance
08:03:01 <flyback> mabye rig up a temp probe or arduino with a temp sensor etc
08:03:07 <flyback> that will shitcan the gen if it gets hot
08:03:49 <flyback> oh arch you have a cap excited/regulated generator also
08:03:53 <flyback> my condolences
08:04:18 <flyback> thats why I am converting some of the noisy ac output to dc using a server grade psu then inverting it
08:04:38 <flyback> if your batteery says no more than .5 c I wouldn't do more
08:04:47 <flyback> it might be fine but overtime it will rape the battery
08:05:06 <flyback> slower charging is always better if you can afford the wait
08:07:44 <flyback> would be insteresting if you could mod a capacitor regulated brushless generator with some kind of m,icrocntroller circuit to get b ette voltage reg
08:08:36 <flyback> I always run my gen with a cheap fan
08:08:48 <flyback> it really cuts the genhead temp like from 400F to 200FD
08:08:52 <flyback> fans are cheap
08:08:54 <flyback> gens are not
08:10:51 <flyback> giving up 60-100w of generator output for a fan is cheap to me to extend the life of the generator possibly by years
08:11:33 <flyback> you could probably rig up a bunch of large dc brushless fans also if you wanted to reduce the power losss
08:14:10 <flyback> be careful btw what direction you have the fans
08:14:26 <flyback> so you don't blow co exhaust into the garage or house etc
08:16:18 <flyback> people and companies skimp on fans cause of noise, cost, lifespan issues but really they are cheap compareed to the device they might be protecting
08:16:30 <flyback> so I might overbuild a fan setup
08:19:59 <flyback> cause I find replacing fans much less bullshit factor than random failures of devices due to heat soal
08:20:33 <flyback> escpially if they build the device with cheap parts, keeping it as cool as possible might compensate for lifetime issues
08:20:55 <flyback> unless you are steve jobs
08:21:47 <flyback> then you are too gay to listen to your engineeers screaming at you that the imac will heat fail cause fans offend steve blowjobs sense of astestics
08:21:49 <flyback> piece of shit
08:22:10 <flyback> he was such as ass
08:22:16 <flyback> he was also a MORON
08:22:40 <flyback> he rampaged about android and windows phone stealing iphone market share when he was dying of canceer
08:22:58 <flyback> **** idiot worry about getting better than you can wage your competitor war
08:24:44 <flyback> only a fool fights in a burning house
08:29:27 <flyback> I like steve jobs as aN amazing salesman but I can't respect shit like worry about crushing your competition when you are chocking on cancer, that's just stupid
08:40:03 <flyback> if you die fighting an enemy, it's a loss
08:46:10 <arch> riiiiight. did you take your meds today :D
08:46:16 <flyback> YES
08:46:25 * flyback has had alochol
08:46:57 <arch> btw it's not such a good idea to overcool a generator. air cooled engines, sure, but engines have an optimum range for how hot they should be while operating
08:47:10 <flyback> probably true
08:47:45 <arch> you cool it too much, you might lead to carbon build up, or valve lash could be too little, etc etc
08:48:01 <flyback> I mean more the genhead than the engine
08:48:11 <arch> oh, then it's good
08:48:46 <flyback> but yeah you need the combustion part to be at a optimal temp so the gasoline burns with maximum potential
08:49:24 <arch> my other generator is not capacitor excited, but it has brushes with rectified dc going to the exciter winding. cool to have 1 generator of each type of technology. now all i need is an inverter generator
08:49:25 <flyback> that's also why I like diesel electric trains and hybrid cars
08:49:46 <flyback> you are keeping the engine at optiMAL RAnge of rpm, tempetc
08:50:02 <arch> i want to get a honda eu2200i, but if those things break, sheesh, expensive to repair
08:50:08 <flyback> yeah
08:51:55 <arch> "multiple failure points: It will randomly shutoff and say the CO detector is end of life and needs to be replaced. The manual states that the CO detector has a 10 year life. Once that sensor fails the generator will not run. " that sucks balls. ill stick with my dumb generators, tyvm
08:52:05 <arch> we die like real men
08:52:19 <arch> we dont need to steenken co detectors or microcontrollers to EFI
08:52:43 <flyback> thst's because co and co2 are hot bulb/heater detectors
08:52:55 <flyback> they aren't trying to screw you out of more money
08:53:10 <flyback> they need a heater circuit to bake the co2/co off the sensor so it resets
08:53:14 <flyback> the downside is a finite life
08:54:17 <flyback> its like a human nerve
08:54:45 <flyback> vx, and nerve agents work by clogging the nerve so it doesn't reset for the next chemical message
08:55:39 <flyback> many gas sensors use heat to fling the gas molecules off so it's ready to detect the new thing
08:56:05 <arch> oo TIL
12:52:42 <MrMobodies> How dare they refer to these things as "STUDIOS" they're not. I thought studios were suppose to be large.

12:53:34 <MrMobodies> That is not a studio. It is a rabbit hutch
12:54:44 <MrMobodies> I thought those bed in the kitchen rabbit hutches were banned 10 years ago but they are still doing this and that's the smallest I have seen.
12:55:31 <MrMobodies> https://www.thesun.co.uk/wp-content/uploads/2022/01/NINTCHDBPICT000704326555.jpg
12:55:56 <MrMobodies> Bet there'd be another rabbit hutch in the next partition where half that window is
12:57:23 <MrMobodies> the image also looks stretched to me vertically to make it look longer
13:05:13 <MrMobodies> https://i.postimg.cc/wH7Tw8zc/Estate-Agent-Stretch1.jpg
13:05:24 <MrMobodies> That light now looks round as it should be.
13:05:59 <MrMobodies> and that overstretched table
13:06:32 <MrMobodies> it seems the image from the window looks alright and not stretched
13:07:09 <MrMobodies> where that overstretched cabinet does not look as overstretched
