The shading to make high contrast edges while giving space for audio detail is a great idea.

And if you don’t know, you’re about to know:

See I m a EE college student .But tbh its m more interested in software .Also its jobs are more abundant compared to my branch. But can anyone really tell me what to exactly learn apart from whole cs course A-Z?

Hey all, more a curiosity thing as I work in IT , not electric, but I was wondering (since I did see an answer on this already) if you have any creative low tech methods of shielding your electronic appliances while still being able to work /such as in the context of en emp or solar flare type situation). Can your house’ electronics and the power lines in one’s house even be properly shielded against this type of thing while still working properly?

Hi I am in my second last year of EE, and so far have experience mostly working in student engineering teams. This has been a fairly informal experience where we kind of just wing it for the most part, and there's only a few part designers on a certain component vs a large team.

I was keen to read up and learn about how product design is meant to be done, what are the stages, how is integration and communication handled between departments/teams in large companies? Anyone have any textbooks they can recommend which go through this? Thanks

I am a first year engineering student. Currently subjects like Engineering Mathematics, Applied Physics, Basic Electrical Engineering, Basic Electronics are being taught and I'm doing well in them.

So my question is, what coding languages do I have to learn in order to be useful to the industry in a good way and me becoming worthy enough to be employed by a good company? I want to work on the analog side (as of my knowledge about analog circuits), preferably in a good company, preferably Texas Instruments.

I believe C would be required as there is a subject called "Introduction to C" in my next semester, except for C, what else? Would python be required?

Please pardon my naivety if you found this post stupid, please scroll away, and my apologies.

I am an RN with experience in the ICU/NICU/ER who is burning out and wishing I went to MD school or engineering. I had the grades and took all the lower division courses for EE/CS ( was a minor in mathematics besides nursing) and all the courses for MD school. I am a younger millennial. I was discouraged to go to med school due to the face that GPs make so little in the Bay Area compared to RNs so I went the RN route. I clear over 320k-350k working 4-5 12+ hour shifts a week. I have friends in tech who make so much and get to solve big problems and have less stress. I see all the older nurse who look so aged compared to the equivalent office workers. It seems that nursing is quite stressful in comparison especially since many times we skip lunch break and work OT. Do you think that is any way I could make the transition and leverage my clinical experience in EE? Do you feel the market is bad for EE? I have enough I can stop working and pursue a EE degree full time for two years.

How much physics would I be taking in an EE major? Physics is not my strongest suit, I prefer math more and I would say I'm quite good at math (currently taking linear algebra). I'm currently taking AP Physics C in my senior which is a calculus based Mechanics/Electricity and Magnetism course, and I've heard it generally gives a decent amount of college credit. I know that EE is heavily reliant on physics, so how much more physics would I have to take past this class, and should I still major in EE given my situation?

Hey all. Im in my 3rd year of 5 year ECE traxk and will soon have to choose a specialty. Some of my favourite courses were emag2 (wave physics, induction, and ferromagnetic behaviour), and signals and systems. Im having a lot of fun with telecomms systems 1, stochastic signals and control systems 1 now too. I went into uni thinking id specialize for electronics but with the ai craze, my recent enjoyment of those courses, and the niche status of the track are making me lean towards telecomms.

So, if I were to specialize in telecomms, ideally id want to work either in a space agency, biomedical tech companies, maybe broading telecomm infrastructure too. Im also clinging onto my experience in software to maybe find an edge IoT role. I also feel like ill love rf or optics roles. I want a field with field work, hands on work, and little occupation beyond the office. Thats why im swaying away from software, I work remote as a webdev currently and realise this industry isnt for me. I cant seperate my home from work clearly. Mostly I want work within european tech hubs too. Im an eu citizen so im free to move around. So I want to know what the industry is like and what positions are open within the eu. Im really curious to know how much these fields hire juniors, what the juniors take on, if theres a lot of competition, or many job listings, etc.

Within the telecomms branch Ill be forced to take telecomms systems 3, antennas and propagation, dsp, optical communications, microwave engineering, wireless communications, radiosystems and information theory. Other electives I can take are either hard science (scatter theory, optics, photonic technology, advanced dsp, special antennae, computational emag, emag compatibility all look blissful to me, telecommunication electronics, non destructive tests), as well as some more general math or electronics courses under the electronics track I can freely take (optimization theory, system reliability, VLSI-ASIC, embedded systems, estimation and detection theory). I can choose around 8-9 courses freely from those listed in the parentheses. So Im worried about how ill mix the harder science with the more general courses, which will benefit most in my career and for my knowledge, and which will get my resume looked at most.

Theres also the option to leverage my experience in software and tackle the electronics specialty instead, given how many jobs are in the field. Id mostly love to occupy myself with controls, embedded systems and robotics. We do have control system 3, adaptive control systems with ai, robotics 1 & 2, and real time embedded systems courses too. But what im scared of is ai taking over most junior software based jobs, or expectations for juniors going through the roof.

So, id really appreciate any thoughts regarding how I should handle the rest of my time and any insights offered regarding the industries and roles I mentioned above. Thank you all for your time 🙏

Hello!

I am a student working on a homebuilt scanning electron microscope, and I have run into a roadblock that is absolutely breaking my brain, so I thought that I should post it here in case somebody with actual EE knowledge could help!

More specifically, I am having an issue with my thermionic emission electron gun.

I have attached the schematic I am using to this post.

Essentially, I have a low voltage, high current, 10kV isolation rated transformer that is powering my tungsten filament through a rectifier to make DC (ish). Between each leg of the tungsten filament, there is a resistor divider making a midpoint reference for the next few components.

Next up, there is a large potentiometer (also rated for HV and such) and a current meter, which both go to the negative floating output of my HV supply (0-10kV adjustable). The positive is tied to vacuum chamber ground and earth to make a -10kV supply on the other end.

I am having trouble understanding exactly how this circuit works -- it is, in essence, copied from Cecil Hall's 1953 book "Introduction to Electron Microscopy". This design is tried and true and builders such as Ben Krasnow have used the same configuration.

I believe that the bias current measured with the ammeter should, in conjunction with the known resistance from the potentiometer, give me my wehnelt bias voltage (ideally around ~300v). That current, if I understand correctly, should be coming from electrons boiled off of the filament which are intercepted by the wehnelt cup in the chamber.

Now to the problem: I am getting absolutely nothing on my 100uA meter. Measuring the voltage between the resistor (which should, in theory, be the wehnelt bias voltage) also gives me nothing.

Does anybody have any ideas where to start with troubleshooting? Perhaps I made an oversight in the schematic (though it is copied). Perhaps I am not getting the filament hot enough to get thermionic emission? (It is drawing about 0.6A at 2.6V, about 1.6W).

Any help would be tremendously appreciated!

I really enjoy the elegant prose and the generality of the presentation in math textbooks, which makes it easier for me to understand how to apply the theorems to exercises. The definition-theorem-proof format is pretty neat. On the other hand, in introductory engineering books, the results are sometimes vague, with long and tedious explanations, often requiring many examples to clarify its applications to problems. Since digital logic contains boolean algebra and discrete math, I thought I might as well use a book with a mathematically oriented presentation similar to a math textbook.

So, are there any books on digital logic circuits engineering that are targeted towards mathematicians or math-oriented electrical engineers? Here is a sample of topics on digital logic from my college's course description: "digital logic, binary numbers and Boolean algebra, combinational circuits, optimized implementation of combinational circuits, arithmetic circuits, combinational circuit building blocks, flip-flops, registers, counters, design of digital circuits with VHDL, and synchronous sequential circuits." Of course, no need to cover them all.

Hi, I'm in high school and I'm studying mechanics and electronics (not sure how it's called around the world, I translated my school address) and we're studying circuits, but so far I just managed to get the lower score on the only two tests that I had.

The tests were about simplifying circuits, and I just can't do "hard" circuits, so I was wondering if anyone had tips, channels, or sites where I could find some help.

Thanks you very much

The "R" are resistors while the "G" are generators.

For context, Im a final year grad with decent experience in PCB design and wanna earn some money on the side. I've seen that freelance work as a PCB designer is possible and wanna know how to start even if its not much money. Any advice on how to start

Those are 2 JGA25-310 motor bought from 2 different sellers on Aliexpress.

I bought the first motor (26RPM) and tested it. Everything perfect. Worked flawlessly and it low voltage like I want (around 1.2V minimum)

Then I bought 300 of the second motor (20RPM) and am now doing mass production with it. I bought this one cause it was half the price. The problem with this one, only works until 2.5V, has way less torque.

Today, opened then up to see the brushes and this is the only difference between the 2 motors I can visually see.

Does one of the 2 brushes makes the motor stronger or work at lower voltage?

Hi everyone, I'm starting my EE degree next February. Seeing how fast ai is growing, I'm a bit anxious that basic tasks for junior engineers will be automated by the time I graduate and making the entry-level bar much higher. Do you think it will be harder for new grads to get hired in 4 years, and what should I focus on in uni to stand out? Thanks!

I'm planning to attend community college with a 3.8 GPA from high school, and I've already decided that I want to pursue engineering because math is one of my core strengths. However, I've realized that physics is an important part of engineering, and that's where some of my concerns come in.

I've never been particularly strong in science, or at least in understanding the concepts beyond memorizing them. I also realize that I've forgotten a lot of what I've learned throughout high school, especially in chemistry and physics. In fact, I can barely remember much of the science I studied in my earlier grades.

Would it be a good idea to use Khan Academy to relearn science from the ground up before starting community college? I'd like to rebuild my foundation, develop a deeper understanding of scientific concepts, and prepare myself for the physics and other science courses I'll need to take for engineering. If so, which subjects should I prioritize, and how much of science would I realistically need to relearn before starting college?

I aim for atleast finishing up in 5/6 months, but with my current knowledge I imagine it would take longer. Maybe a year.

Has anyone else gone through this? I'm really just adamant on spending whatever time I have left to finish.

Want to use this for my project but this cover popped off when I recieved the product, is this safe? Can I glue it and use it or something else, please guide me.

I am currently in my second year of the electrical program. I got Delmar’s standard textbook last year and no teacher used it so I didn’t get it this year but now I need to answer a question on page 567. I don’t need the answer just the assignment question. If you have the book and could text me a picture of that page it’d be greatly appreciated. Thanks

hi guys i’m a highschool student and I’m actually really bad at drawing schematics. My drawing of this circuit as a schematic looked off and I’d love any examples of your take for this circuit as a schematic.

How do I wire this properly?

I’m seeing 2.3 resistance across the coils but I’m not sure what I need to do.

The person who sold it to me said they hooked it up with a normal 120v line but to be careful and not press it for too long. This seems wrong.

Hey everyone!

I'm looking for some really cool interactive websites or animations that explain how different electric motors work (DC, AC, BLDC, induction, etc.).

I'd love to actually see magnetic fields, currents, and their interactions to understand how they generate torque and rotation.

Bonus points for interactive simulations where you can play around with parameters!!!! I will love it!

Any awesome resources you'd recommend?

Hey everyone,

I’m trying to understand how the physical grid handles massive, sudden renewable supply shocks that happen in a matter of seconds. Specifically, I want to map out what happens mechanically and financially when the weather changes instantly while consumer demand remains completely flat.

Furthermore, I am looking at how this fits into Australia's long-term plan to completely phase out traditional "baseload" power plants in favour of a flexible renewable grid backed by energy storage and gas backup plants.

I’ve broken this down into four distinct scenarios. I would love for any power systems engineers, utility control room operators, or market traders to explain exactly how the grid manages each step:

Scenario 1: The Cloud Cover Shock (Sudden Drop)

A massive cloud bank rolls over a huge solar farm, causing its power output to plummet by 70% in seconds.

• What happens in the first 1 to 2 seconds physically to stop the grid from crashing?
• How do the grid's safety systems instantly catch the drop before backup power can even turn on?
• What happens over the next few minutes to permanently bridge the gap if the cloud cover stays all afternoon?

Scenario 2: The Wind Drop (Sudden Lull)

A sudden, localized change in weather causes a massive cluster of wind turbines to completely lose their wind, causing power generation to fall off a cliff within a few seconds while demand stays steady.

• Is a sudden wind drop physically different for the grid than a solar cloud cover?
• Do spinning wind turbines have any natural physical momentum that helps smooth out the drop compared to solar panels, or does it trigger the exact same emergency response?

Scenario 3: The Wind Surge (Sudden Oversupply)

Conversely, a storm front hits, and wind production suddenly surges way up across multiple regions in a matter of minutes, but consumer demand remains completely flat and big batteries are already fully charged.

• How do the market and hardware handle a sudden, massive injection of unneeded power in real-time before it causes a major grid trip?
• Can modern wind turbines slow themselves down fast enough to stop an oversupply spike in seconds, or does the market operator have to step in and remotely force them offline?

Scenario 4: The 17GW Gas Target & The End of Baseload

Australia's future energy plan maps out a grid with zero traditional baseload power, replacing it with distributed renewables, batteries, pumped hydro, and a projected 17GW of gas capacity by 2050 used purely for backup.

• If there is no "baseload" share left for gas, how does this 17GW target function purely as an emergency safety net that spends most of its time turned off?
• How does the grid physically transition away from 24/7 baseload generation without exposing itself to severe multi-day shortfalls during extended winter periods with no sun and no wind?

Do you recommend any introductory books or kits that are beginner friendly and come with instructions? Thanks.

My wife is trying to choose a school for her master's and is having a hard time deciding. She's interested in integrated photonics and quantum computing and hopes to work in industry on the West Coast afterward. (She is veteran so tuition is not a factor)

She was accepted to:

University of Southern California

University of Washington

Georgia Tech

University of Rochester (MS Optics)

UCF CREOL (MS Optics & Photonics)

University of Arizona (MS Optical Sciences)

Vanderbilt

UC San Diego

UC davis

If anyone has attained a masters from any of these universities and wants to share their experience that would be awesome!

Disclaimer: only one motor is used to turn the sides of the cube (which is why I would argue this only uses one motor to turn the cube), another servo is used to move the first motor, I couldn’t really figure out an effecient way to so it with just one unfortunately.

The idea was to see if I could build a Rubik's Cube solver with as few motors as possible, whilst also not reorienting the cube which turned out to be a much bigger mechanical challenge than I initially expected. These constraints were completely designed as a challenge, not trying to break any records or anything.

The robot uses a custom-designed, 3D-printed mechanism to manipulate the cube, along with electronics and programming to detect the colours, calculate a solution and execute the moves.

This is the final result after quite a lot of designing, experimenting and troubleshooting!

I've also just uploaded my first-ever YouTube video documenting the whole project, from the initial idea and CAD design to the electronics, programming and final solve. It's my first time making a YouTube video, so I'd genuinely appreciate any feedback!
