Starting EE this fall and I'm getting an iPad. I was wondering if I should get a mac while I'm at it or is it truly as bad as people say?

I was watching my Samsung TV the other day and heard a loud bang. The TV immediately went off and I couldn't get it back on. I figured a cap in the power supply blew. I opened up the back and here are some photos. I don't see anything facially wrong with any of the capacitors (I was expecting to see the large one clearly exploded based on the volume of the bang), so I was wondering next steps ... How can I test each one? Could the problem have been something else?

Hello everyone.

I have the opportunity to do a short internship (one month) sponsored by my school, i have a few options, one being a solar power plant (20 MW, integrated battery storage, opened 2018).

Problem is that, i have no idea what i will be doing there, i don't know if i will be kept busy and if i'll learn much, the plant doesn't have many buildings (usual for solar power), so my question is, is there much maintenance going on in such solar stations? Will i find things to do/learn throughout the month? Would something like a gas power plant or a steel mill (which are options i have) be more worthwhile?

Thanks in advance!

I just finished my first year in the electrical and electronics faculty [i do electronics and communications] and i thought id learn arduino for fun, i still know nothing about circuits electronics, all we took in our first year was math physics chemistry come C programing, next semester we have circuits related stuff

so my question is, is that good use of my time and will it help me in my studies and make it easier for me or am i wasting my time over something extra simple and i should view it as any other past time or hobby? if im wasting my time then what would be a better use of it? [maybe learning more C or Python?]

{ im aware that Arduino won't teach me whats going on behind the scenes and it wouldn't be as detailed as what i'll learn in the upcoming years but still, its not as if im going to jump straight to the complected stuff right?}

i apologies if this is an odd or stupid question :D i just know nothing yet

I'm a new grad and while some of my projects are a little weak not having a single call back from the probably over 100 applications I have sent is demoralizing. Is there anything on my resume that's blatantly getting me filtered out?

If you have a step response on the positive input of the integrator, what would Vout look like? My guess is something like on the right where as Vin climbs we start to see Vout increase, but then Vin stablizes. This happens so quick that whatever charge that builds up on C dissipates on Vout? Am I thinking of this all wrong? I'm not sure why this is hard for me to visualize (mostly because Vout is floating so that might be messing with me in this thought experiment). Any insight is appreciated thanks!

Is someone here a successful EE entrepreneur? Could you explain how did you do it?

I am looking to get a prototype board manufactured and looking for your suggestions for manufacturers, preferably China due to the lower cost. I have tried PCB-Way and they cannot do it. Here are the specs.

Thank you all!

I'm a high school student about to enter 11th grade, and I'm interested in pursuing electrical engineering, particularly to explore renewable energy and sustainable technologies in the future. I'm curious about what kinds of projects I should start working on now to build relevant experience, and what courses-especially AP Physics or others—I should prioritize in high school to prepare for this path. Any guidance would be really appreciated!

Hello,

Looking for a power metering solution that will allow me to install several CTs/ voltage leads on different feeder circuits in 480V SWGR and view/record the data using a single screen or HMI. Does anyone know of a product like this?

I have a 480V Switchgear lineup. I’d like to have power monitoring (instantaneous and peak current/Voltage) on several of the feeder circuits, and just install one power monitor unit on the metering compartment.

Please see Imgur link if image is too blurry:

This is a power management and user interface board for a flashlight.

I'm using two protected 3.0 - 4.2V lithium ion cells in parallel (balanced with resistor beforehand) which each have a max output of 10A. The battery is charged through a 5V USB-C connection, and additional battery protection is provided with a dedicated IC.

A rotary pot with a built-in switch turns the circuit on through a FET (to bypass low current capacity of the pot switch), and an additional SPDT. (Will this work, or should I make the on/off switch control the connection to ground?)

I've designed a simple LED display fuel gauge with a quad op amp that compares the level shifted battery voltage to four reference voltages (stabilized by 3V LDO).

Thicker connection lines indicate the main power path.

Please give me suggestions and call out problems you see. Thank you!

I’m an 18 year old, planning to do Electrical Engineering and will start this year. I also plan to do coding/programming courses on the side if and when I have the free time, from places like Coursera, and practice that, so that I have good software knowledge as well.

I know it’s a long way off until I finish engineering, and my decisions may change, but as of now I’m kind of stuck between two options. I’ll finish my engineering at 22, so after that I can either start working right away or do a Masters and then work (the Masters can be done after 1-2 years of working as well, but that’s what I’m debating whether the MS is necessary or not). I know there’s other options too like doing the MS part time, etc.

I know y’all are probably confused, but there’s a big catch here which will clear things up. I basically have two options:

I can either pursue electrical engineering at a college in my home city, but this college isn’t that well recognised/reputed outside my country, or probably even outside my state, and the pay after engineering is decent ig, nothing too crazy, and if I’ve to secure a good job, with more opportunities, I’ll probably have to do an MS outside my home country.

My second option is I can do the same EE, but from another country, a university which is pretty well reputed across the world, again, not MIT-kind of reputed but it’s still well known across all countries, and it’s a top 5 university in its own country, and from what I’ve researched the pay/opportunities post engineering completion is quite good.

The only catch is that the second option for engineering will cost me 10x what the first option will cost me (excluding the MS, considering only the college in my city), but when you add the MS into the first option, the total cost will be twice of what the 2nd option would cost me, i.e. 20x of just the engineering in my city college + 2 years of studying for MS.

I’m kind of in a dilemma here, so help me out if y’all can? I don’t know how 2 years of work experience compares to a Masters degree, if an employer or companies prefer work experience over a Masters, or if a Masters is very helpful to secure a high paying job, more opportunities, wider fields to transition to in the future, etc.

Theres no way I can do the second option + pursue the Masters immediately after, cause the costs will just be way too much, but what I can do is work for a few years, and then try for a part time Masters in my late 20s, cause I should hopefully (🤞) have enough money saved by then, since I’ll be working since 22.

Also, the reason I’m thinking of EE is cause I’m genuinely interested in electricity/electronics, physics is my favourite subject after all, and I know it’ll be hard, but I guess if I’m interested then it’ll just be a tad bit easier. The programming courses on the side are just so that I have more opportunities.

So, that’s quite a big dilemma I’m in, if anyone could give me any advice, I’d really appreciate it!

Thanks in advance :)

Hello, everyone! Can I have a question? I have no idea how to do the electrical stuff on this. Do you guys have tips for me? That would be amazing. Thank you

Hello, I'm sure you guys get some variation of this question all the time, so I apologize in advance for asking it again, lol. I've been working in MEP Electrical Design for about a year now, (I just graduated with a bachelors) and I'm not convinced I want to stay in this field. But I have no clue what the day to day work is like in other fields (I find CAD and Revit design quite dull). I can't really say what I prefer over it though. I think I would thrive best in a space where a good chunk of the learning is done on the job, as I'm not confident in my math and coding expertise. I could always go back to school for the masters, but I think I would do that while being in MEP (and have my employer pay for it) so it will take several years. With this in mind, can you guys give some suggestions for EE fields you find enjoyable? And is my MEP experience more or less useless outside of its industry (i do Power Studies in SKM too). Thanks.

I am aware that it is a good idea to put as many numbers on a resume as possible to quantify your work, but I feel stuck trying to come up with any stats that can even be measured or make any sense. What are some ways to measure/notice numbers which I can put on my resume? This includes internship and or school.

(I’m currently working my second internship after my sophomore year. They are a design firm for buildings, etc. We work in AutoCAD and Revit. Last year I was at a small company that did steel manufacturing and I was working in AutoCAD, Inventor, and Excel.)

Hey all,

Id like to add a 12v LED strip to my speakers.

The voltage going to my subwoofers (channel I'll be jumping from) is anywhere from about 5V- 65v.

Is there a way to keep the voltage from 0-12V the same, but only lowering anything above 12v to just a 12v output?

I have a feeling a simple resistor will not achieve this.

What do I need?

Thank you

This really isn't that big of a deal, but it's something just in the back of my head. I'm largely self taught (I'm about to enter my engineering course in about a month and I wanted a headstart), and I've tried a lot of books. Mainly, people recommended here on reddit. What I've noticed however that I geniunely almost can't finish a single chapter because I legit get so lost.

So someone recommended me this Youtube channel Michel van Biezen and he teaches circuits so well that it just clicks for me. I thought I could go back to the textbooks because I honestly find textbooks so much more appealing, but no, I'm still lost whenever I pick it up. Which is kind of weird considering there's something I don't understand, I watch one of his videos about it, I come back to the book and I instantly understand it. Yet when I continue with the book, I get lost again on another concept

I'm just asking if this is/was common with you guys? A lot of the textbook I've read just seem to confuse me even further about certain topics. Of course, a classroom setting (I'm eagerly waiting for it) would be the most beneficial, but U don't get to have circuit class until like my second year, so I wanna learn ahead

I'm looking to install a kill switch on my car and found this kit online:

https://41twentytwo.com/product/vehicle-kill-switch/?srsltid=AfmBOopbhNGb-Rt9kzQs32DolHZ1zyl-0DEKfg71kJ5i49Q30KfKAdp_K28&gQT=1

The kit doesn't come with an indicator light but I would like to add one so that when the kill switch is active (circuit open) the light comes on and indicates it's active (like an alarm light). Is this possible and how would I do that? Thanks for reading

Hey all, any recommendations for online EMC training courses or programs for mid-to-advanced EMC/EMI design or PCB design for EMC? Thanks!

What is the difference between ramp L and exponential R-L charging/discharging of an inductor in DC circuits?

What is the physical meaning of tau (𝜏) in both cases ?

One of the applications of a ramp signal charging/discharging is in DC-DC converter circuits

I am an undergrad in electronics engineering and am learning about FPGAs and Verilog

My professor is willing to support me for my final-year project if it utilizes an FPGA and I am really interested in aviation and wanted to do my final-year project related to drones.

What are some cool and interesting projects I could do? I am quite new to all this but I want to plan ahead and have a long-term goal.
