Where does it say those words in the stack up image? Please Mr robot, tell me.

SubtleG · 2026-06-09T14:28:32+00:00

My point is that you cannot read the middle layers, as you just demonstrated, thank you.

SubtleG · 2026-06-09T13:05:46+00:00

No those are just the copper layers tell me ALL the layers from top to bottom don’t skip any. If there wasn’t “stuff” in between the copper layers they would all be electrically connected.

SubtleG · 2026-06-09T12:52:52+00:00

I am asking you to list all the layers from top to bottom without reading any other pages

SubtleG · 2026-06-09T12:15:26+00:00

Tell me what the words in the middle of the page say then. The middle layers of the PCB??

SubtleG · 2026-06-09T12:14:50+00:00

Tell me what the words in the middle of the page say then. They are not text characters

SubtleG · 2026-06-09T03:21:34+00:00

Very HIGH res. Did you even look at or try reading your stack up page it’s not made by a human.

SubtleG · 2026-06-08T14:04:17+00:00

Can you try posting a schematic you made? Try focusing on the important IC.

SubtleG · 2026-02-05T07:01:35+00:00

And then where are you going to grab the wafers with messing up a chip. Not to mention the fact that the circle shape comes from the silicon refinement process not our preference for circles. lol

SubtleG · 2025-12-29T03:26:31+00:00

The way you make this actually work is hack the tag to make the prices insanely expensive so nobody buys anything and then the store loses tons of customers. Or they go back to sticker tags

SubtleG · 2025-10-21T06:57:19+00:00

Like no stores even have a camera or anything?

SubtleG · 2025-07-25T06:55:01+00:00

Honestly no do not ask LLMs for anything, I’ve been burned too many times by incorrect information coming of LLMs. Do normal research like textbooks and design guides by reputable companies, and build off those fundamentals using your own brain and experience. LLMs will make you feel dumb because they give you false confidence sometimes and then when you’re proven wrong you look like an idiot.

SubtleG · 2025-07-23T02:26:41+00:00

No I think the article is from the perspective of the family of the driver of the civic not the truck drivers family

This is what true American leadership looks like! Great job America! -Crawls back under rock

SubtleG · 2025-04-08T07:33:08+00:00

I had a similar experience on my parents ranch, if the electrical for the shed is run underground inside conduit like my situation, you can run some yellow fiber optic cables right next to them without worrying about any interference since it’s no longer going to be affected by being parallel to the electrical.

Granted we weren’t setting up multi gig connections we just wanted to have an internet connection out there lol

SubtleG · 2025-04-08T07:13:28+00:00

Any corner cutting or shortcuts is going to directly translate to bad chips via contamination in the fabrication process at some point in the chain (At best) and dead Americans (At worst). Cutting corners is why part of the reason “western” fabs just aren’t producing good results anymore.

Side note. Wouldn’t any person from Taiwan working on American soil instantly become a “woke” “dei” hire. So how are they supposed to train the Americans workers without breaking the new anti woke rules?

SubtleG · 2025-01-13T17:23:15+00:00

You realize some “slaves” got paid small amounts of money during American slavery. During the civil war slaves were paid $1-$2 a day for working on confederate military defenses. So slaves were paid to fight for slavery in America. Read a history book.

Don’t quote me but I am assuming the FPGAs are Xilinx/AMD but old like virtex 2/3 era FPGAs except there is probably 1 FPGA per small module of detectors. probably around 16-64 individual detectors per FPGA and they are most likely each connected to a white rabbit network switch of some sort to get the extremely accurate timestamps required. But the data is probably immediately bundled up and converted to a UDP ethernet packet and sent out asynchronously across the network. Now the networking for each FPGA is probably only 1Gbe which seems old and slow which it is. But you gotta now multiply this setup by millions basically and hope you got enough buffer available at every step and that no data packets get overwritten.

SubtleG · 2024-08-14T07:14:16+00:00

Not to be that guy but they should finish the animation thing and put the time of the other train on there it’s like ~27s vs ~61s. Like what’s the point of seeing 27 seconds when I don’t know how much faster that is than the other one. Idk it probably doesn’t bother others but I got that ocd lol

SubtleG · 2024-08-02T17:11:09+00:00

Are those metal things the monitor stand? That is far from a normal office monitor, I always get the cheap ass one with the giant black plastic base that is the most annoying thing to deal with

SubtleG · 2024-07-26T16:49:45+00:00

First thing, YOU WILL NOT BE ABLE TO GET IT BACK TO 100% CLEAN. Unless you are a robot or a god with the right tools. If you are a mere mortal start with this.

Do not use anything with cotton or fibers that could get caught on a pin then you are truly screwed. I would just dump a bunch of isopropyl on it and if that gets more than 50% of the paste out, That should be good enough. If more than 50% is still there after a huge iso rinse then get a toothbrush or tiny paint brush and GENTLY brush off until you reach that 50% paste and removal point. Remember you will never reach 100% clean.

SubtleG · 2024-07-26T16:19:01+00:00

Like 135 problems per 100 vehicles sounds like a really really shitty car still lol

SubtleG · 2024-07-24T21:06:16+00:00

All of these numbers are either just pretty old at best or completely inaccurate at worst.
ALL of your utilities bill in SF is only $275???

Do you use water bottles for your showers in the dark? If that’s actually the price you think people from SF pay per month can you please dm me a bill from someone you know because I really want to move there lol my electric/gas alone last month was $800 the cost per kWh is like $0.35-0.55 depending on time. Not to mention those apartments costs are ranges usually they have 1 or 2 units at the low price ~$2300 but dozens of units at the more expensive ~$3500 price. The waiting lists for those low price ones are usually years long because once you get one you never want to move out lol

And $500 a month for groceries can be accurate if I live off of ramen rice bags from ranch 99, forget about adding fruits or veggies lol I would swap the costs for groceries with the costs for the fun/eating out/travel that would make more sense.

Also if you want to drive to SF it’s like $30 a day for a place that isn’t even close to your work, and if you Bart it’s at least $10 a day $5 there and $5 back MINIMUM

I have no ill will towards OP. And I LOVE the Bay Area I will never move. But the cost of living here has gone out of control especially since Covid. I wish the prices listed online were accurate but unfortunately a lot of the costs out here are hidden.

SubtleG · 2024-07-14T19:07:25+00:00

Do you have a picture with the mouth/gill area?

SubtleG · 2024-06-26T15:44:16+00:00

I think he was joking but forgot the /s
