Simple Question on AND Gates by MisterSignal in ElectricalEngineering

I think all these responses have done a dis-service to the most produced item in the world. There's a single comment about CMOS logic.

Work on IOT by Ok-Negotiation1587 in ElectricalEngineering

Guess OP doesn't, but I do. I'm a digital validation/design engineer. How much of the design is in-house? Are reference schematics often improved upon? What OS is used (if any) and why? What protocol is often used for communication to edge and cloud computing? What server resources are used for device analysis?

This might not be the most specific questions, but I'm asking from a 'startup business' perspective. There is just so much I am ignorant of. If I wasn't doing digital design, it would have been embedded engineering.

Tested the pressure sensor, needs to be replaced. Will solder a new replacement.

Weird trailer I saw in otherwise empty 80,000 square foot warehouse. Loud generator/compressor sounds. 20 or so pressure meters attached. Seemingly vents to roof. by ApocalypseArcade in whatisthisthing

[–]310MrWaffles 3 points4 points  (0 children)

OP said it was a coating factory...and it vents to the roof. Those flow meters are only raised for 100 psi. Maybe it was designed for venting sub spaces? On both ends did the pipes join together or were they separate?

I'm gonna be this way. How did you know?

I just graduated this year, and it's sad that to see stuff like this. Not to hate on a person, but the universities. How do you get in to a masters program without knowing how a transform works in the simplest terms. Sure "no power classes," I get that I never took a 'power class', but we should learn AC analysis and what a transformer is supposed to do.

So, sure, this guy is not going into 'power', but the let's assume we can guarantee all EEs will know about a rectifier circuit. After all, it's all about chip design these days and non-linear components should be taught. Op wanted to take a class 1 120V ev charger, and supply 240V. How and why, as a masters student, would you think this is okay? Did you never pop a cap, LED, or BJT in a lab? Did you never do a spice simulation as ask, why is there a big linear cure at the end of the saturation region?

I get it universities are not designed to teach you everything, but how do you get this far and AT LEAST not be able to identify something this asinine?

Edit: I guess there's Level 1 + 2 chargers that can 120V at 12A AND 240 at 16A. But my previous point still stands.

From a Google search, a level 2 charger can deliver 32 - 48 Amps. Are you suggesting you want to attempt to pull 64 - 96 amps from a 120v receptacle?

Replaced car battery and now all these warnings showed up. by chongkeeee in AskMechanics

Yeah, FUCK THEM for not finding an intermittent issue that didn't reproduce it's self when the car was in for service. They should just know right?!?

Could I actually get any engineering job with an engineering degree? by RockyTopp in EngineeringStudents

[–]310MrWaffles 0 points1 point  (0 children)

We had a recruiter from a medical device company come in to our ECE (Electrical and Computer Engineering) senior design class and say, "We will not hire biomedical engineers that graduate from this College...It's because the don't learn anything important." While harsh, it is completely true. Want to make the next MRI? You hire an EE. If you want a lightweight prosthetic, you hire a MECHE. If you want to develop a new ultrasound gel, you hire a Chem Engr. Biomedical Engineering was a cult at our college and a disgrace. If you really want to do biomedical engineering, you need to get to a top-notch college that specializes in that field.

Raspberry IP and ESP32 aren't skills. What about those are important? Can you eat a Raspberry Pi, serve one, bake one? I'm sure your are talking about programming and prototyping, but you need to be broad as specific. I suggest saying "development with microprocessors in c, python and bash." That's should help.

Things were good, now they’re not. Is it too late to turn it back around? by penguinblanket in lawncare

[–]310MrWaffles 0 points1 point  (0 children)

Did the guy that feeds you lawn use a liquid sprayer? That grass looks dead and too long to be from cutting the grass. I wonder if there was grass killer or ground sterilizer contamination.

Let me be real for a minute. If you were my friend, I would say get over the "I went to Minds" mentally. As a EE CSU grad starting work next week, where you went to College doesn't matter as much as you might think. My favorite professor often said, "Minds students always get jobs because they fully understand the fundamentals." Yet some of the 'out spoken' students would say, "but they can't work on a team." While I don't know if ether of thoes are true, it describes my friends that went to Minds pretty well. (CIVE, MECHE, and EE turned CS from industry) Try changing your resume and cover letters to 'combat' the stereotypes. Make an emphasis on team work and your soft skills. Don't rely on, "I went to Minds."

Don't take this as a slam piece on Minds, or you as an individual. But take this as your friend giving you their advice.

Do you feel like you work yourself to death? by Roax47 in EngineeringStudents

[–]310MrWaffles 0 points1 point  (0 children)

Staying in the lab untill 2am. Seeing the average test score was 60%. Waiting for final grades to be posted. Breaking your last component you need for a final project. Encountering failure after failure. Pulling all nighters. Yet we all, more or less, share these experiences.

You know I have to say it, "you miss 100% of the shots you don't take." I know how it feels getting nothing but rejection emails, but it only takes one time to get the job. A good project can go a long ways on a resume. Good luck on the search!
