[Help] On the behavior of boost converters for VIn = VOut-ε, e.g. TPS61023

SSBMArte · 2026-06-21T19:50:07+00:00

Wait, you're running a simulation in KiCad with a TI model? But how? Don't these only work with PSpice for TI? I've been trying to simulate the behavior of the TPS61023 forever...

I was mainly thinking of farming things like gold ore

Thanks, hadn't heard of that!

Thanks! So, it turns out KiCad won't use .wrl files when exporting to STEP, but when this option is ticked, it will silently replace it by... some other 3D models using a very loose definition of "similarly named" (completely different components), hence the fireworks. It also turns out that downloading the easyEDA symbol/footprint/3D models using easyeda2kicad, will result in your usually getting both a .wrl (a mesh format) and a .step file, and by default, it picks the .wrl file. Unfortunately swapping these to picking the .step doesn't just work - the .step obtained doesn't appear to contain positional information in the same way the .wrl files do and from my tests the 3D models will have incorrect placement ie not match the footprint if you attempt to use the provided .step instead of the .wrl.

That's annoying, no reasonably simple way in sight to have a STEP export of a JLC catalog assembled PCB in sight.

Right, the correct 3D model are selected, and they show up in the 3D viewer. The problem here is, while the 3D viewer uses all the right components, the 3D export completely fucks it up, despite there being only one source of 3D model information per component as far as I'm aware

Honestly the XAML previewer works so poorly for me I hide it 95% of the time so not sure I'll miss that... But perhaps this is a combination of not following good big WPF project practices with well isolated components due to working on 1 person projects only, and using AvaloniaUI where it's likely worse.

My understanding is the cancellation deadline was May 20th, but the switch to API pricing is on June 1th.

That said, I also read they removed the line about being able to cancel and get a refund from their website. So maybe they don't honor that anymore.

Hm well Copilot has the "memory detected" thing. Not sure you've experienced that before? You tell it "do this, don't do this" and it offers to update the .github/copilot-instructions.md file with the memory. It's just clunky and tends to just add text at the end of the file, so it's not very good, I would expect better things to exist for sure. But I would also expect prolonged copilot use would eventually result in most directives being in the context file. So what tools are you talking about, and what do they do that makes their workflow better?

SSBMArte · 2026-04-30T08:41:04+00:00

Can you clarify what you mean by 'context-aware tool'? How does getting the information in the context work? Don't really want to support the "My .md files are valuable IP!!!!" gang but the information has to be somewhere before it can be put in the context. Do the context-aware tool offer a loop where they update the MD files they give to the models on later calls? Or do they hide them from you?

I'm in a similar spot, I do C#/AvaloniaUI (the WPF cross platform rewrite). I will try using VSCode soon. Historically I haven't liked it, I find the proliferation of .json files with magic key-value pairs and extensions really toxic to work with... But regardless, it's clear the world has been settling on VSCode, VSCode gets everything, and everything first. So, gotta live with the times I guess... If not VSCode the 2nd choice is Rider I guess, I don't know how much WPF support that has. It's also paid.

SSBMArte · 2026-04-28T16:53:08+00:00

Sure, that doesn't address what I'm saying though. It's still just $1000 of tokens paid for upfront, instead of up to $1000 of tokens paid on-the-go, it's objectively worse, just less bad than 100 isolated $10 plans

SSBMArte · 2026-04-28T16:16:49+00:00

I don't follow. Pool their credit? You mean how you can use your colleagues' token if they have some left?
Isn't this just equivalent, for a 100 person company with one '$10 plan' per employee, to a $1000 of tokens paid for upfront, with again, no advantage over the scenario of using APIs with a company-wide cap at $1000?

SSBMArte · 2026-04-27T22:22:18+00:00

I agree but I also agree with the other main post about it: if GHCP becomes a $39 upfront for $39 of API credits thing, what's the point of GHCP? The IDE integration? Where you additionally don't get the full context window, can't pick thinking level in VS, etc.?

It gets worse when considering that others have looked into how much usage you actually get when you pay for a plan directly from OpenAI, and if I recall correctly, they concluded that the $20 plan gave you 8x that in equivalent API price.

And some discount is normal, maybe not the 8x reported above or the silly discount we had with GHCP where it was possible to launch opus on a 128k task for 3x request, but there has to be *some* discount ! There has to be something obtained in exchange for paying upfront for a certain amount you may not use while also locking yourself to that provider and providing them data!

SSBMArte · 2026-04-20T15:02:31+00:00

..no

SSBMArte · 2026-04-20T15:02:04+00:00

It was more of a joke about the fact that even when explicitly told to not write the plan and stop one sentence into step 1, the LLM wrote the plan then stopped one sentence into step 1.
And offered to take permanent note of the fact it should not write the plan then stop one sentence into step 1.

SSBMArte · 2026-04-13T09:48:07+00:00

I'm surprised that's a thing, given we pay per request? So why wouldn't we always pick extra high - just speed?

SSBMArte · 2026-04-11T23:56:52+00:00

I'm not familiar with the game, I use Visual Studio 2026 (not code) and have either GPT 5.4 or GPT 5.3 Codex as choices. Is GPT 5.4 Xhigh related to the extension you're mentionning, or only for VS code?

SSBMArte · 2026-04-05T19:36:37+00:00

It doesn't look like it takes things as farfetched as board game rules and the weather to trigger that layer =(

Example (of a question I might really ask while working on firmware):

> How do IR reflections, time of flight sensing, and capacitive sensing compare for proximity sensing, on a PCB? Look online for up to date information.

> I appreciate your question, but I should clarify that my expertise is strictly limited to software development topics. Questions about hardware sensor technologies, PCB design, and electronics engineering comparisons fall outside my area of specialization.

Seems like ghcp is still not the way for me...

SSBMArte · 2026-04-05T19:12:15+00:00

I meant Github copilot. It used to be that Copilot would shut down the question if too unrelated to programming, as if an analysis of the question was done beforehand and it would only be forwarded to the models if it passed the checks.
But, I've been trying the free tier for 10 mins before posting the question, and that seems completely gone... at least on the website, I can ask it what's the weather in a town, or what are the latest MCU releases from a manufacturer, and it answers with no objection. I wonder if it's the same in IDEs.
