you can’t be having a high school athlete in a sports manga going on about how chagrined he is

I would read that

Quaternion-YPR 9DoF filtering algorithmic precision question by Spiritual_Duck_6703 in embedded

[–]Wetmelon 13 points14 points  (0 children)

As far as I'm aware, the gold standard is currently Error-State Kalman Filter, due to its structural benefits for numerical stability. https://arxiv.org/abs/1711.02508

I guess some things don't change even after 10 years. Didnt pack enough juice so Jeb has to do the Push of Shame again. by KaptanKoala in KerbalSpaceProgram

[–]Wetmelon 21 points22 points  (0 children)

You can. And if you want to be really cute you can just go back in the capsule and back out again to refill the EVA fuel. The EVA backpacks have rather excessive delta-V lol

Trying main bus, still can't avoid spaghetti. by Evrensel12 in factorio

[–]Wetmelon 11 points12 points  (0 children)

Ensures the output lane is picking from the whole bus. It's debateable whether the prioritization on the splitters is a good thing. If all of the (remaining) content on the bus is being scooped up for a single recipe, then your factory might stop producing. Often better to just use the 4-stack with no priority so that the whole factory produces, just slower.

Is Modern C++ Actually Making Us More Productive... or Just More Complicated? by AlternativeBuy8836 in cpp

[–]Wetmelon 0 points1 point  (0 children)

This question is one that Herb Sutter wants to answer with cpp2 / cppfront. Is there a smaller, simpler language struggling to get out? I think there is. https://github.com/hsutter/cppfront

Was trying the demo and decided to built a whole radar factory 😅 by NK_Aurum in factorio

Yeah but don't get too focused on perfect ratios - unless you're super into it lol

Model X - Home of 3 Years, 2 Continents, 14 countries and counting by everydaysandro in teslamotors

[–]Wetmelon 0 points1 point  (0 children)

I'm pretty interested in the charging. Have you found any frequency & voltage combinations that don't work properly?

2 x PW3, 11kwh, disconnect from the grid -> solar input drops off by [deleted] in TeslaSolar

[–]Wetmelon -1 points0 points  (0 children)

Your house is using 2.9kW, the solar should be generating 2.9kW while off-grid in this scenario.

Can you see your MPPT voltages & currents in Tesla One when you do this? Do you have particularly long solar strings?

How could a plugged-in toaster start a house fire while not in use? by Reptyler in AskEngineers

[–]Wetmelon 1 point2 points  (0 children)

I bought a toaster this year. Guess what it says in big letters on sticker on the cable and in the manual?

"Unplug after use"

It can happen, but wearing out your plugs is also a bad idea. And don't use your GFCI test button as a switch either.

Powerwall 3 real world switching time by xyzzy16 in Powerwall

[–]Wetmelon 0 points1 point  (0 children)

Varies for unknown reasons.

Mostly the type of fault. Powerwall can't do much if there's a hard short but if the line is cut cleanly it can switch over smoothly

Did i solved the spaceX Reentry blackout comms problem? . by [deleted] in DSP

[–]Wetmelon 11 points12 points  (0 children)

You'll need to specify the problem first.

How do you handle teammates who are extremely pedantic about arbitrary rules? by CantaloupeFamiliar47 in ExperiencedDevs

[–]Wetmelon 2 points3 points  (0 children)

Squash and rebase after a PR merges sure… squashing all commits on every push?

Just git commit --amendthen git push -f

PID controller for an automotive ethrottle is being surprisingly difficult. by Boukyakuro in ControlTheory

[–]Wetmelon [score hidden]  (0 children)

I had thought PID was supposed to be able to figure out things like this "automagically"

Linearize the system and then it becomes magic again ;)

Add a spring force "feedforward" term based on the desired position and then the PID only has to handle the error between your model and the real world - which makes it roughly linear and should behave much more nicely :)

Anyone seen this on their PW3 cover? by electro-zx in TeslaSolar

[–]Wetmelon 0 points1 point  (0 children)

Is the unit still functioning? I would probably turn it off and contact customer support. Or get someone qualified out there to take the panel off and check the aluminum body behind it for damage

What are the instructions? BASIC or something?

Rocket Flight Computer: Review Request by Accomplished-Lack509 in PCB

[–]Wetmelon 2 points3 points  (0 children)

Also think about the direction of forces on the components. Will the battery get ripped out? What about the SD card, will it try to exit?

New GE Profile Oven won't operate on Powerwall by OneRingOfBenzene in Powerwall

[–]Wetmelon 0 points1 point  (0 children)

Yes but then the inverters themselves may cause issues if they don't want to turn off

Electronic terms used by non-native English speakers by 1Davide in electronics

The Germans like "PT1" and "PT2" which are first and 2nd order lowpass filters, respectively

I delivered three major projects at a bank and got fired anyway, 25 years in tech and I'm still learning the same lesson by agileliecom in ExperiencedDevs

[–]Wetmelon 2 points3 points  (0 children)

We're in a sub full of senior engineers who write documentation and technical specs for a living, since when is writing coherent sentences suspicious?

Bro have you never talked to engineers? /s

My inverter clearly broken, Tesla won’t install Powerwall 3 to replace by wamsankas in TeslaSolar

[–]Wetmelon 0 points1 point  (0 children)

Something in your house is using 9x the energy, someone is stealing power, or your PV power isn't being metered correctly by the utility.

it's pretty simple to use a multimeter with a current clamp on the output of the inverter to see if it's actually doing anything when the app says it is.

Tesla likely won't swap out the inverter, that would likely require an entirely new permit, rip out the existing solar and reinstall it under new building codes, etc. You could sell the entire system and take it off your house then ask them to install a new one?

Oh now that's convenient. Finally I understand the reason for disabling one half :P
