How bad is job hopping viewed in this field?

19 Upvotes

I'm on my 3rd job. I started off at my first job 3 years ago and despised it completely. I left within 10 months and landed another role for about 20 months and didn't get a raise so I started looking elsewhere.

I just started my 3rd job and am going to stay 2 years at the minimum, but am concerned about the same thing happening. Sometimes a subfield which might have seemed interesting turns out to be miserable, or maybe I run into a case of the 2nd job where I get literally zero raises or promotions.

I get that I'm supposed to show some loyalty, but I'm not really willing to abuse myself that much. At my 2nd role, I knew senior engineers there with 10+ years of experience making sub-100k in a HCOL area. It's just ridiculous.

Made this based on a Daisy seed 3. The music is auto generated. There are 8 different sounds in the mix and all of them are connected individually to a pair of filaments.

It's a very rudimentary sculpture, but its my first of it's kind.

I was inspired by Eirik Brandal's amazing creations.

Hope you like it.

Education Why Arm is more efficient than x86

55 Upvotes

Hi I'm in an undergrad processor architecture class that's covering risc cpus and I was wondering what part of the architecture in arm cortex cpus make them more power efficient than a typical x86 cpu like your Intel and amd chips. I asked my professor and he more or less told me that it's how arm based processors use a combination of 16b and 32b instruction sets vs x86 using all 32b instructions but just wanted a bit more clarification and explanation on the topic. Thanks!

Jobs/Careers What is the best way to utilize time while looking for jobs?

• Upvotes

I am a CE who just graduated in June, focusing on grid modernization software & power systems. I had an internship that ran from the day after graduation until the end of August. No return offer so I am unemployed now. I have had one interview so far after ~60 applications (I think most I am waiting to hear back on since they are more recent, interview was around my 15th application).

I am scheduled to take the FE in the middle of September, but what do I do after that? Any particular project focuses that will be most valuable?

Would appreciate any input on what I can best use my time for right now

Does the Force-Current mechanical analogy make sense?

• Upvotes

Hi guys, i'm not an engineer, just a technician. For the longest time i have had trouble getting an intuitive grasp around the basics of circuits: voltage, capacitors, inductors, etc. Then i read about the Force-Voltage mechanical analogy and suddenly it all made sense: Charge being analogous displacement, current to velocity, voltage to force, capacitor to spring, inductor to inertial mass, resistor to friciton/dampener. Suddenly the behaviour of the components made intuitive sense.

Then i read about the Force-Current analogy, and now i am lost again. Current acting as a force? Voltage as velocity? Magnetic Flux as displacement? Capacitance as mass? I am lost again.

Does that analogy make sense? Is there an intuitive way to understand it?

Jobs/Careers Halfway through my degree but I don’t want to work as an engineer

42 Upvotes

I’m an electrical engineering student currently on a co-op entering my third year. I love what I’m learning in school and I’ve always envisioned myself doing something rigorous and having a proud title like engineer.

However, for probably a year now I’ve been having turmoil about the thought of working as an engineer for the rest of my life.

Now that I’ve been working all summer and will continue through the semester, it pretty much confirmed my doubts. I hate working a typical 9-5 in the office sitting at a computer. My current co-op is pretty great objectively; I get to run test on expensive hardware, I’m running my own design project from start to finish (the exact thing I wanted to do originally that made me choose EE), and a bunch of other stuff. It’s a solid view if my future career. I don’t hate it but I’m just not happy working a job like this for years on end.

I know it’s shallow to complain about great job security and pay, but I just don’t know what to do. I’m gonna finish my degree it’s just hard for me to swallow my pride and not be an engineer, especially if it pays less. I just can’t imagine myself doing anything less than that, which I know is an issue on my side.

I want a less technical career, specifically I would love to teach or lead. But getting my PhD and fighting to become a teaching professor is not any better, and a high school teacher has different struggles that make me hesitant. On top of it I’m getting married at the end of the year so when I graduate it’s not like I can go run off and jump between jobs and do something crazy, I need a tangible career with a proper trajectory.

I just feel lost and would love to hear some thoughts. Currently I’m a president of a student org at my church and I love it because I drive our organizational growth and community engagement by directing student outreach, running events, managing administrative operations, and representing the group externally. This type of role gives me passion and I’m not sure if there’s a career like this out there, especially with my degree. I’ve looked at some director jobs like director of student affairs and what not but I’m unsure.

Any thoughts are welcomed, sorry for the long post 😅. Long story short I don’t want to be stuck at a computer I want something that engages me and every day is different. Has anyone gone through something similar? It’s hard for me to drop engineering from my life but I don’t think a typical career in it will make me happy.

imposter syndrome is killing me

7 Upvotes

im a first year electrical eng student at a pretty prestigious university in north america. my fall semester last year was pretty tough. i managed to scrape by but then in my 2nd semester my study habits got very flimsy, was feeling super burnt out, mental health was declining, which in result had me to repeat the entire 2nd semester. the rule for my uni is if you fail more than 2 courses, you have to repeat the semester. this not only delayed my grad by a year, but overall derailed my journey of graduating on time with my other peers.

what kills me the most is that only 2-3 students in my class ended up in the same situation as me. which means chances of me failing would have been quite low, but i still managed to hit rock bottom. some advisors told me to
consider looking at other eng, but i really feel committed to my current one and am currently pushing through. i just finished 3 out of my 7 courses during the summer semester and will be back again in the fall with the new freshmen

overall, my morale seems to not be getting any better. maybe this is the result of being a high achiever throughout my life until university. maybe this won’t seem like a big deal after i finally graduate, but right now i feel i don’t belong in my class at all :,)

What basics should I learn before exploring different ECE domains?

0 Upvotes

im a first year ece student . Before jumping into any specific domain,What are the most important basics I should learn first?. for ex mathematics , basic electronics, programing etc .

Is there a common foundation that will make it easier to explore different ECE domains later? Also, what would you recommend learning during the first year?

Jobs/Careers Didn’t get the Internship

10 Upvotes

I was just given news I didn’t get the internship that I interviewed for. Interview went awesome I thought. The only thing they said was the lack of autocad experience. I have experience in multiple other cad softwares including solidworks, which is harder than autocad in my opinion. Is it really that competitive? How do I market myself to let these interviewers know that this stuff is really damn easy for me, and not having experience in a specific software (that I could learn in a couple days, beyond what they probably use it for) shouldn’t be a reason to pick someone else?

I’m trying and failing to not take this personally! I’ve been jaded in this job market ever since I was laid off, a few months prior to deciding to go get a degree in EE.

Should I buy a 3D printer?

0 Upvotes

I’m a college student studying EE that loves to tinker and make things. For example, I spent the last 2 years building ground and satellite sensors. I’m thinking of investing in a 3D printer in the next few months for personal projects.

Has anyone done this?

Do you have any cost effective and quality machines you recommend?

What else should I think about investing in materials for personal projects?

Thank you so much in advance

Equippotentual Bonding conductor AND a CPC?

1 Upvotes

It is my understanding as per BS 7671 that metalwork is either an exposed consecutive part or an extraneous metallic part, not both.

If it's exposed, it typically gets a CPC. If it's extraneous, it typically gets an equipotential bond.

E.g., exposed metal casing of an electrical appliance gets a cpc. Metal pipe or steelwork gets an equipotential bond.

Is there ever a scenario where something would get both a CPC and an equipotential bond (as in the two as separate connections)?

What about in a substation?

Education How much do your elective subjects matter?

0 Upvotes

So I am currently in my undergrad last semester from a third world country. I'd like to pursue my masters degree abroad with aids and scholarships. So as i was about to explore options (yup the visa problem is acknowledged) we are required to pick our elective courses for the next semester. My undergrad thesis is in the field of implantable antenna design but i haven't worked much on it yet. And I'm also unsure if i want to continue with implantable antenna in my masters. I'm a bit interested in embedded systems but i just have a quite medium level project on smart access control system implementing esp32 with a web server to grant any requested access with live streaming along with a manual password rfid card access and probably a position on our departments line follower car competition. However the elective course situation needs to be sorted first. I'm attaching my available options below.

There's 3 different pools from which we need to pick 1 each, where the 1st pool comes with sessional courses. The theory courses are themselves 3 credits each. I'd really appreciate any kind of recommendations you have regarding the elective courses selection. TIA

A. Pool 1 (theory along with sessional)

  1. High Voltage Transmission Systems

  2. Biomedical Signals, Instrumentation and Measurements

  3. Optical Fiber Communication

  4. Radar and Satellite Communication

B. Pool 2 (only theory)

  1. Smart Grids

  2. Photovoltaic System Design

  3. Multimedia Communication

C. Pool 3 (only theory)

  1. Power System Operation and Control

  2. Wireless Communication

  3. Compound Semiconductor Devices

Would love to hear your thoughts on my club/idea

0 Upvotes

Ok

Background: Current Freshman like a week of knowledge. So first I go to a small private school without a lot of engineering clubs other than maybe FSAE (very new), IEEE and those weird engineering frats. My school isn't well known so I want to stand out through this and build some cool things because thats why I got into engineering

I have the idea of making cool projects with my friends 1st yr. We are thinking of making a drone with an umbrella that follows your around using phone gps so that rain doesn't get on you. 2nd project is like a roomba but for grass so it automatically cuts grass outside so you don't have to everyday.

Once we get those done (hopefully one every 1 semester) we reach out to companies 2nd year and show them what we made and kinda pitch them a partnership for a product or something they want built (hopefully through alums or profs). They could provide funding, materials, or an engineer to mentor us, and we would build and test a prototype for them.

The goal is to make these projects similar to a senior design or capstone project, where students work on a real problem from a company and present the finished project to them. If the company is happy with our work, it could lead to more projects, stronger partnerships, and potentially internship opportunities for students who worked on the project.

We would also document the projects through our website and YouTube channel so companies and students can see what we have built. Over the four years, we could grow the club, take on more advanced projects, bring in more EE, ME, and CS students, and eventually have multiple teams working on different projects at the same time.

Troubleshooting 2 set of Microphones give no signal

Sup nerds. I know nothing of electronics so im merely joking about the previous statement as I admire what you do and are interested in. I am a music technology student who works with electronics and microphones and such i just don’t know the inner workings of the equipment. I was gifted a set of microphones from someone who has a studio that I have been mentoring with outside of school and he gave me them because 1 of them didn’t work and the return on them was a hassle and thought I could put them to use. 2 of them actually don’t work and they are a cheap knockoff brand so if i can’t even fix them its not the end of the world. I pulled this out of it and does any of it look off or like it might be the issue?

I acquired an old spectrometer and wanted to hook it up to its respective PCI card for talking to a computer. unfortunately one end is db25, the other is dc37 and the cable is unobtanium. so i crimped my own :>

i bought crimp db25/dc37 connectors and a metal shell and then sacrificed a DVI cable which gave me just barely enough conductors to make it work. and it does work!

Pursuing a masters in EE from a Bachelor of Music Undergrad

0 Upvotes

I have an undergrad degree in Music Production and Engineering from Berklee and am looking to get a masters in EE.

Curious if anyone has any advice about bridging/pre masters programs, primarily in the US as from what I can tell these programs don’t usually offer visas in the EU.

Also, I’m currently in the first year of an EE HBO bachelors in the Netherlands, so by the time I would start a bridging program fall ‘27, I’ll have more of a foundation (calculus, physics, programming, etc)

Any advice is appreciated!
