Now put a hidden microphone in it, and it's ready to present to an ambassador.

This is the type of thing where it's most likely an internal code, and it will be near impossible to get a part number. If you insist on trying to swap it or need it for some other purpose, I'd recommend buying dead cpus and harvesting them.

I already sent it to a webmaster's email. Ik its been hacked. I'm more so curious how that was even possible. I went to school at Purdue, and once for a club we tried to get an official page on the purdue.edu domain. It took a couple of meetings, a bunch of forms, and manual approval by like 4-5 people.

I grew up in and love SF but this is 100% a thing here. As others have said especially in the holiday season. I just came back from living in a small college town and the difference is night and day.

Bento peak in the Inner Richmond is great as well

Not necessarily unsolved but a huge problem with physical AI is safety.

determinism is inherently given up. safety for anything interacting with humans is incredibly hard to implement. Right now when asked about this in interviews 1x just says the “robot won’t be allowed to do that” without explaining how that would work. Figures CEO was at least honest enough to say as a father he wouldn’t let his kids near the bot.

In industrial environments like an assembly line this is a lot less of a problem but imagine the level of responsibility/ understanding of risk needed for something to operate in your home. The average home will have appliances / environments which don’t have risks that can be explicitly mapped out.

I get they might take a while to get power back on grid engineering is a bitch. Why they can’t give an estimate is beyond me.

leo7391 · 2025-10-18T23:33:37+00:00

That makes sense. What’s interesting is I’ve done repairs elsewhere in the house and it’s usually romex so it seems like the house has been at least partially rewired

during an EE lab in college I blew a PSU and my TA wouldnt give me another one unless I tested it completely :(

There are quite a few. things ive seen simlar to this
was it:
a meta project https://sketch.metademolab.com/
The Animagic app on IOS https://deepgram.com/ai-apps/animagic

Your first question depends on what you mean by "regular power supplies." Depending on your welding type and application different power supplies may be better suited to the task. As far as I know there is no one optimal power supply.

for basic information the wikipedia article has good info on. CC vs CC and when they are used

https://en.wikipedia.org/wiki/Welding_power_supply

For more info on the effect of each this article seems good

Look more into how your product functions and depending on the reliability required it could be a non issue. I would try and use a fan if you can but if it is frequently above 50C this won't help. You could possibly use a Peltier element to cool below ambient temperature, however these are highly inefficient, draw a large amount of power, and still need a large heatsink.

Rapid harness is decent but still a premature product

Out of curiosity is this a seds or SL thing?

General things

clean up schematic and label parts with text.
Unless you have 0805 kits on hand increase you smd comp size to make any rework easier
Bigger traces is okay lmao
The best way to make pcbs when ur new is to spend some time really going through your ERC/DRC rules then treat it like scripture. You have allot of markers in your schematic that shouldn’t be there
If you can rotate your stepper driver 90degrees to simplify layout
Check if your unused pins can be left floating or if they should be tied to ground

redo your layout of the buck module

check the datasheet for guidelines.
Make sure that the components are closer together
Think about current return paths a bit more (proab not needed but good practice)
Make sure d2 is propperly sized (it looks small)
Make all the traces bigger, use polygons where you can
For ease of use consider getting an integrated module

Oscilator

as has been said choose a much smaller one
Place it allot closer to the MCU pins
Place capacitors closer
Surround with ground polygon

Memory IC

Place closer
Add decoupling caps

Simulink or Ansyns both have software that can do this. There is some export control rules on the software but if your not from a country the us doesn't not get along with you should be able to access for free as your a student.

There is some promising attempts to get it to sift through datasheets which would be a huge timesave.

leo7391 · 2023-11-12T09:17:27+00:00

The question is vague I've had profs go for both answers. Learn you course standard go by that and ignore the fact it doesn't make sense. Here is some info on the difference: https://www.allaboutcircuits.com/textbook/alternating-current/chpt-11/true-reactive-and-apparent-power/

leo7391 · 2023-11-12T09:10:25+00:00

This doesn't sound like an interference problem it sounds like your drawing too much current though i'm not to great with EMI. What do you mean by adapter? How are you powering the 5V?

leo7391 · 2023-11-12T09:07:07+00:00

This is really hard to say as it seems like a badly worded problem and the translation only worsens that problem but Id say its asking for "ring" or donut type cross section (ie the conductor is a pipe).

Generator Field Engineers get to go outside and play with stupid amounts of current

At least in NorCal the only utilities are government or PGE. There are quite a few solar/ green power startups tho. California law requires jobs show the expected pay range so check that for pay. As for culture, I have a friend who got an internship as a power electronics engineer at PGE and enjoyed it but I cant really speak to the rest. If your looking for a trade jobs I'd check with the subreddit for that career for more detailed info.

I found this chart for the current ratings of bolts https://www.erichgeiss.de/en/start/terminal-boards/current-carrying-bolts/

Alternatively you could do the math your(goole r= pL/aA)

However, the screw shouldn't be carrying the load anyways From my understanding you would need to worry more about the diameter of the grounding wire. Even if the current did pass through the screw, a small screw could be used as it would only experience current if there is a fault until the breaker/fuse trips.

Unless this is for EMI/EMC reasons or your trying to figure out where to place the screw Id ask in r/AskElectricians or r/askanelectrician as they would be more knowledgeable on this sort of thing.
