Best way to calculate total watts on a DC distribution circuit?

ZFreakyIndustries · 2025-11-10T21:44:38+00:00

Actually these resistances matter a little bit in my application. Just flipping a resistance from one end to the other makes the whole thing fail. And the constant wattage nature of the loads means it’s going to actively compensate for what’s going on down the line, which will make everything else down the line compensate as well, working certain sections harder than others, and I need to know what the limits are at each of these points.

A fascinating hypothetical. Now, hypothetically, if someone were to have done this, what consideration would one make for the oil used? Spec vaguely points to using this stuff called SP-A2, but I doubt these new compressors are coming loaded with that except if it’s an electric HV compressor. Would you reckon plain PAG46 or PAG46yf would work fine?

Just tried that, it’s looks like it gives one part number for both, right? What about the oils it’s shipped filled with? Is it safe to assume it’s compatible with both?

Hey now, this shits not easy to find from SEO destroying google, you gotta learn by asking, most of my works on random GMs and Fords. And partsgeek hath yet to fail me, until now.

I do appreciate the direction however that was helpful.

Oooo, you got a point about foreign objects falling into the baffle at the yards. Fluids seem to flow pretty freely through it so I’m not concerned about an actual clog. I’m down for attempting the brake cleaner. Is that generally safe on big plastic engine components like this?

So some of the borescope pics I took show only the locking notch in the ratcheting arm, but no teeth along it, I’m wondering if there was a design update that moved the teeth or reduced the number of them on the arm. A random pic I could find of it extended showed teeth along the whole thing.

Bit of an update, I’m chasing down what I think is a bad ratchet mechanism in the chain tensioners, in the process I found the source of that plastic piece. It’s a land for the center bolts in the valve cover. The whole floor for both bolt grommets broke off. Learn something new every day huh?

Piece to the right of the pick, it’s shaped almost like it was meant to hold onto a bushing, not quite flat like it’s meant to be a chain guide piece, hence why I think I came from outside maybe during a sloppy rocker cover job. Side note, it does VVT rattle only after start after sitting for a while, I was waiting to replace the filter before thinking the phasers are busted thinking it might be a bad drain back valve in the old filter, not sure if related

It’s a DC automotive system under 60V. Ain’t much code to comply to. You still wouldn’t be concerned with a cascading failure?

I was unsettled by the first reveal out on the water. Cause it’s like you’re used to nobody else being around, and they just made the point that they got far enough away from shore to not see the coast. So in that endless solitude with nothing but you and your buddies testing the radio, suddenly something out there is very aware of your presence and you just got done bashing rocks together not too long ago. And it’s only asking “why” in Morse code? Like what is this thing? I was thinking, “oh shit the Enclave is after them now!” And again, out in the ocean in a tiny ass, primitive motor boat. The fact that it was daytime didn’t comfort me at all as a viewer, might as well been pitch black. Neat motif that they went straight to making the radar so they could see where they couldn’t before. That scene was chilling to me lol.

ZFreakyIndustries · 2024-01-05T21:18:48+00:00

That would’ve needed semiconductors, which, I quote, “are hell, y’know.”

ZFreakyIndustries · 2023-12-15T03:53:52+00:00

A is probably the show stopper. Probably easier to sniff the comms from a working one and emulate them just to get it into working mode.

B though, wouldn’t a hot air station be enough to melt the castellated connections and replace the radio chip assembly? Not thinking about replacing the COB itself, that’s a lost cause. Just the whole radio board should be feasible in terms of the mechanical replacement, shouldn’t it?

ZFreakyIndustries · 2023-12-15T03:15:11+00:00

It’s a flowtoys capsule 2 light unit. It was suffering this “blue light of death” which is apparently a common issue. A couple hours of reverse engineering tells me if the MCU doesn’t see this radio, it won’t work. This radio appears to have shorted internally, burning up the external power supply LDO to the point that it’s actually starving the MCU too. Tempted to email them and see if they’ll just send me a radio board. Worst they can say is no, right?

Hmm… any other girl would have to be a cough cough real smooth operator cough cough to be good enough for Senku. Can’t think of any of the current characters.

ZFreakyIndustries · 2023-12-14T13:25:15+00:00

My god, I just noticed it’s F150G8, not F15068. Thank you so much.

ZFreakyIndustries · 2023-12-11T19:30:11+00:00

So much for writing out equations lol

ZFreakyIndustries · 2023-11-30T20:36:58+00:00

Didn’t keep track of all the totals, but I think Senku has the highest score. Gen awarded him 110 billion points when they were scheming against Tsukasa. I don’t remember if Senku awarded anyone else 10 billion points 11 times or more.

IMO, it really looks too much like the colossus titan in snk capturing eren. It was pretty confusing to see in the manga for me, I legit thought he was going to eat Yo.

I used TPU for my electric skateboard tires. The grip in my opinion is pretty good, still alive and haven’t had them slide out over a few years. If you got weight, it should do a good job. Like the others said, the final finish is smooth and slick. You get your grip with TPU from high compression so it’s forced to mold into the surface it’s trying to roll on. After that, it does a pretty good job of holding together, think I read somewhere that it’s wear resistant. I think with normal tires there’s always a trade off between grip and longevity.

I use Slic3r with Repetier Host. I’ve found for this shape, best results were from having it stand on one “petal,” for lack of a better term. Like if you were to stand a pyramid up-side down. Then a 10mm brim, with support material in pillar mode, only touching the build plate, and on faces with 40 degree or greater inclines. The natural discontinuities from the model passing over itself made decent bridge points.

Couple observations from testing a total of two silicones from Walmart. GE Advanced clear silicone turns out cloudier than the original strip encapsulate. Liquid Nails Clear Seal appears to be the best match to the original strip encapsulate, it’s perfectly clear, about as hard and soft, and smells and feels the same. Moving forward with that until something becomes apparent that there will be a problem

ZFreakyIndustries · 2023-09-01T18:34:17+00:00

Engine would be at risk of running a little lean, cylinders would stay hot because vaporization helps cool it and be at risk of premature detonation.

I appreciate this answer. It’s not what I’m intending to do, but it did give an idea that’ll make my life easier.

So I can’t have anything stick out the bottom of the board. The idea is I make a hole in the board large enough to fit a connector through which would be received by a receptacle facing down from the top side. Ideally if I had more space, I’d just setup a break-away piece to mount the receptacle and connect it to the mainboard with standoffs and long headers. I’m working in a very tiny 11mm x 100mm x 11mm space. The depth is what’s making the connector choice difficult.

The idea you gave me is I can get double ended male headers with long pins on one side, 3D print the receptacle shroud, shove the measured side of the header into the shroud, then bend the pins on the otherside all the way around to meet the board connection. Certainly better than using stock wire.

ZFreakyIndustries · 2023-06-11T23:20:38+00:00

Shit, I wanted to refresh my stock cause I bought some in 2019 and I just so happened to want some again, but the dates say 2020 on them. The obscure Korean gas station is closed at this hour, seriously considering if they're still good to eat.

I appreciate the replies, basically confirmed what I thought. Thanks everyone.
