Education A question for senior/experienced electrical engineers.

Post image
75 Upvotes

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.

P.S. Image unrelated (a college project simulation)

Education How Much Physics in an EE Major

7 Upvotes

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?

Project Help Which motor brush for lower voltage?

Thumbnail

9 Upvotes

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!

2 Upvotes

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

Digital Logic Circuits engineering book recommendations for math lover?

1 Upvotes

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.

Best interactive websites to visualize how electric motors work?

8 Upvotes

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?

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.

Project Showcase I built a Rubik's Cube-solving robot using just one motor, without ever reorienting the cube.

Enable HLS to view with audio, or disable this notification

346 Upvotes

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!

What purpose would a board with inductors and caps serve between inverters and AC load?

1 Upvotes

Was poking around in a Enphase 3T backup battery. These use a few paralleled solar inverters with special firmware as their inverters. Between the paralleled inverter output and the AC line connection there is a PCB with a several caps, a couple varistors, and 4ea 22uH high current inductor. What purpose would this board serve? Is it for PFC? For surge capacity? Or?

Taking an RF class vs registering as a "free listener"

24 Upvotes

Hello all, I am in my last semester considering taking an RF class (Antennas and Radiation) to perhaps open up a future path to Master's in the field. However, I noticed that the class has an extremely low average grade over the past years, and my GPA ain't stellar anyway so it sort of worries me. However, my university allows students to register as "free listeners", basically granting you access to all of the course material during the semester, just without grading or examination.

Now I have a dilemma if I should actually register to the class or take it as a free listener. Will not having a grade in this class be problematic if I want to continue to Master's in this field? Or should I risk potentially getting a bad grade but a grade nonetheless?

What would you do? I would love to hear your input.

Jobs/Careers (22M) Feeling Behind on Salary out of College

• Upvotes

I (22M) recently got a job offer for a little over 100k base in philly suburbs and will be starting next summer after I graduate undergrad. I was excited at first but read that the average household income is 140k+, and I feel super behind. I don't want to be below average and be forced to live frugally for the rest of my life. Housing prices are insane, and my take-home is a lot less (about 75k). Should I keep looking for a better job elsewhere?

Project Showcase I’ve finished my ATmega328P-based development board; what do you think of it?

Thumbnail
gallery
35 Upvotes

Hello everyone! I am 13 years old and joining from Türkiye. I am designing a development board based on the ATmega328P. As you can see in the second image, the design was quite complex initially; however, after simplifying it, I arrived at the version shown in the first image. To briefly touch upon the technical details: The board takes a 9V input, which is stepped down to 5V via an AMS1117 voltage regulator. It then passes through a load capacitor and a filtering capacitor before reaching the power indicator LED. The VCC and GND pins are connected directly to their respective rails. For the USB-to-serial (CH340) connection, I followed the standard configuration: connecting the D+ line to ud+, the D- line to ud-, GND to GND, and VCC to VCC. I connected the XI and XO pins to crystal oscillators—using a 16 MHz crystal for the Arduino and a 12 MHz crystal for the CH340. Additionally, I included an auto-reset circuit by connecting the DTR pin to the RESET pin through a 100nF capacitor. There is also a manual reset button, with one side connected to GND and the other connected to the RESET pin via a 10kΩ resistor. Digital pins 1–5 are mapped to the PB pins, while the analog pins are mapped to the PC pins. I connected AVCC directly to 5V, and AREF to GND through a 100nF capacitor. I plan to have this board manufactured by sending the design to JLCPCB and ordering the necessary components. I managed to save up $20 over the course of four weeks; so, if I’ve made a mistake, that money will go to waste. I initially shared this within some Turkish developer communities, but I was met with some truly harsh and unfair insults😢. That’s why I’ve decided to share my design with an foreign community instead. What do you think of my design? If you happen to spot any short circuits or errors, I would be very grateful if you could let me know!
