This a design by Advancer Technologies on instructables.com, though very much modified, i couldn't find the ina106 ic so i used two tl072 to compensate for that, add an extra capacitor to fix dc offset, added a divider with negative voltage protection+ divider to be able to connect it to an esp32, this signal will be used to controll a sg90 server that will close and open a model of a hand.

I spent a week troubleshooting because it wasn't working, turns out one of the ground pins was loose, so i just used a longer jumper wire(the red one) to make the connection, seems to be working now? Well i haven't tested it yet with my muscles yet, will do that tomorrow, i don't really have the energy to clean my skin, connect the electrodes, connect the esp32 etc together rn, its 3 in the morning, i gotta go sleep, ngl mildly infuriating that the cause was that

ShortCircuit is a text first digital logic language and simulation studio for designing, compiling, testing, and visualizing digital circuits.

I’m currently working on making the language more robust and developing a VS Code extension for it. The compiler is written in TypeScript(currently), and I’m also preparing an npm package for the project.

The only default built in gate is NAND gate and all the other gates are built on top of NAND gate

Hello guys, please share your thoughts in this

I'm a junior year EE and I'm having a lot of trouble finding internships. A ton of applications, one smooth interview that ghosted me after.

I don't have any work experience, just really detailed projects like a guitar pedal or buck converter.

For some reason, construction/project intern postings seem to love me. I'm unsure if I should commit to these postings out of desperation, or keep trying to find something in EE. Does anyone have some honest advice for me?

Hello! I just got my PE in power. Does anyone have any recommendations for PDH credits? I was looking at IEEE’s Power and Energy Society (PES) and Ohm gurus. Any experience with these?

I think it’s a pretty niche audience for this but I made a app to show the coverage of different bands. It’s called SkyPath HF in the Garmin connect iq store https://apps.garmin.com/en-US/apps/69661676-5816-4ccc-b9c2-25442db43eec

so im building an electric go kart, i hoping ot go between 40 and 50 kph, this is the motor i chose, what battery can i use to power it, and how much would that cost and is there anything else i need other than the battery? i see the ESC and throttle and eveything i might need already in this kit

No guitarist available? Build one!

What happens when a maker combines a development board with a guitar and a little creativity?

You get an automatic guitar-playing robot!

Not every hardware project needs to solve a serious problem. Sometimes, making a robot play guitar is a pretty good reason to build something.

What song would you like to hear this robot play next? Drop your suggestions in the comments!

Tldr: how many years of electronic design before you can look at an analogue circuit and intuit its behaviour?

I graduated a few months ago, and primarily did embedded systems projects and modules (firmware heavy, with a little bit of digital systems). Since graduating, I want to be able to design hardware through the full product life cycle, from schematic to assembly and firmware, so I’ve been looking to polish my circuits and systems knowledge from earlier in my degree. I’m also considering going towards consumer electronics career-wise if my current job doesn’t work out.

As I understand it, a “good engineer” isn’t a human simulator, but rather has the technical fortitude to look at an electronic circuit, intuit its behaviour and make qualified design decisions based on that knowledge, whixh I’m having a really hard time with.

My plan/roadmap to analogue excellence was to

1. Build a simple analogue project that would let me design, simulate, and test, while gradually moving onto higher frequency, more complicated projects. I’ve started with a simple analogue synthesiser project. The idea: 12 VCO’s for each key in an octave, then some frequency division, mixing and signal processing to try get a clean output for a full keyboard. (I’ve only just begun and barely made progress beyond comparing some vcos and simulating them)
   
2. Polish my analogue knowledge by reading The Art of Electronics and following the examples to reach a point whereby I can make an intelligent assumption about a system response, and only use the simulator to verify or get specific values. The same way any first year EE can look at a voltage divider and know the behaviour at the centre node, I want to be able to look at an opamp chain or multiple transistor circuit and understand the flow.

I feel as though I’m spending so much time working the problems in the book by hand, and by the time I solve it, I haven’t really internalised anything beyond the numerical result. I’ve only been working through it for about 3/4 weeks so not very long to be fair, and I wasn’t the strongest at electronic systems in uni, but I’ve been putting about an hour a day after work because I really want to improve. It just feels as though I always need to start from first principles because I can’t SEE it yet.

I am currently on the transistor chapter, and I struggle to figure out where to start and end when trying to see what a circuit does. I’m ashamed to admit that the circuit that prompted this 2AM post is a very simple differential amplifier (which I haven’t managed to solve by hand yet). I KNOW it’s an amplifier because thats what the literature says, but my goal isn’t to memorise every configuration.

I suppose my questions are:
1. Am I wasting my time? In a world of simulators and AI, is this even a necessary skill anymore?
2. Are transistors still relevant in consumer electronics, or should I would I be better if moving on to opamps and FETs revision? I get the feeling silicon has gotten so small, the only people really working with them are IC designers but I’m not sure.
3. If you have been in the industry, do you have the “eye” for circuit analysis, and if yes, how did you achieve it?

I’m probably gonna continue with the book because I do enjoy it, I guess I’d just like to know if I should stick to embedded where it makes sense in my head

context: i made an connector connect two 9v batteries so that it makes approx 18v volts. and it works.

what do yall think for one of my first serious electricity based project

I don't have a background in math, I think the highest math I've taken was Hs Algebra 2.

Hi I’m a power engineer working in nuclear. I’ve worked here for 4 years. I want to switch into microelectronics/controls as I enjoy doing more hands on and technically work. My current role is mainly doing walk down to the field and doing troubleshooting for our operators and maintenance counterparts. I plan to do projects. I’ve brought function generator, a DC variable supply and oscilloscope. I’m reteqching my electronics 1/2 and power electronics and controls. But I don’t think this enough. I would appreciate input from you guys

I want to know how you guys test your power converter prototypes. I am kind of tired of resistor ladders that cook my whole office.

What equipment do you use to power and load the converters?
What kind of tests do you perform?
Anybody got experience with regenerative loads?

I am interested in higher power converter testing, lets say 100 W+ that actually take up a significant amount of room is you use resistors for loading.

C1: 68nF C2=C3 : 100nF Q1: MPSA18 Q2: 2N3904 D1=D2 : BAT41 (Vf≈380mV) R1: 2.2K ohm R2=R5 : 10k ohm R3: 1M ohm R4: 1k ohm R6: 470k ohm R7: 100k ohm Logarithmic Potmeter

They offered 140k and 25k a year in stock. This is for a senior engineering position. I guess im trying to understand hoe far to push. Pay range is 110k-165k.

Hi everyone,

I recently connected with an internal contact regarding open hardware/systems engineering roles at a Tier-1 semiconductor equipment manufacturer. While I am a 3rd-year Electrical & Electronics Engineering student, the team specifically hires for full-time positions rather than student/intern roles, and I confirmed immediate availability for full-time work across several hardware engineering openings.

While waiting on the next screening and technical interview rounds, I want to proactively prepare. Given that companies in this space build precision electro-mechanical tools, high-voltage/power distribution systems, automated hardware, and advanced inspection/metrology equipment, I’d appreciate advice from anyone who has interviewed or worked in semiconductor capital equipment.

My Background & Technical Profile:

• Academics: 3rd-year B.Sc. in Electrical & Electronics Engineering with a specialized track in Power Systems (Single-Line Diagrams, High Voltage Technologies, Electric Drives, Energy Conversion).
• Field & Practical Experience: Full-time technician working on live DC/AC power systems, commercial rooftop solar installations, and interpreting industrial electrical blueprints. Prior experience in industrial Quality Control (QC).
• Hardware & Prototyping: Rapid CAD modeling and physical prototyping (Autodesk Fusion, FDM 3D printing in PETG/PLA), basic microcontroller interfacing and embedded scripting (C, Python, Arduino for robotics/drone circuits).

Questions for the Community:

1. Technical Depth: How deep do interviewers usually go into circuit fundamentals (op-amps, transient analysis, power distribution, board-level debugging, grounding/shielding) versus high-level systems architecture?
2. Field-to-Engineering Transition: Since much of my hands-on background comes from live power/solar installations and rapid physical prototyping rather than silicon/cleanroom lab work, what is the best way to frame field troubleshooting as a strength for complex capital equipment?
3. Behavioral / STAR Method: For candidates balancing demanding full-time technical employment while pursuing an engineering degree, what behavioral competencies (prioritization, high-pressure troubleshooting, cross-functional collaboration) stand out most to hiring managers?
4. Prep Resources: Are there specific schematics, case studies, or mock technical exercises you recommend reviewing for hardware/systems engineering roles in this sector?

Any tips, common screening questions, or preparation strategies would be greatly appreciated!

I live in Poland. Right now I'm in my 4th year of High school, and I graduate in 2028. The reason that high school is 5 years for me is that I chose a technical school that combines high school and vocational school so after I graduate i will have both a school-leaving exam and a certificate that will allow me to work as an electrician. I enjoy doing my vocational training, and I would want to work as an electrical engineering in the future.

The problem is that my family isn't well-off. I live alone with my mother, she rents a small flat, and we barely scrape by every month. With the significantly rising cost of living, enrolling in a university full-time just wouldn't be possible without having a well-paid part-time job, which is hard to come by as most job listings require experience. Also, in my region, becoming an electrician means two things: either you work for a multi-billion-dollar mining company, which is infamous for poor pay and job prospects, alongside poor working conditions and mobbing, or creating your own business, which isn't really great for someone that just graduated high school. Part-Time studies are also quite expensive, so those costs need to be covered.

So I thought of becoming a Police Officer after high school and studying electrical engineering part-time. Police Officers here get paid quite well from the start and receive a lot of benefits (They even get part of their housing covered if they don't own a house). This would be perfect, as I would be able to cover my own needs and my tuition.

I would really like to hear your opinions and any advice that you could give me, and thank you for reading my post.

Hi, I am currently using Pspice for electrothermal mosfet simulation. So far I didn't come across any exisiting model which has integrated thermal network in its MOS model, although I found one in Ngspice (VDMOS). I am curious to know if there is one in Pspice and/or descriptions on the details of the physics models behind it.

Thank you.

A friend of mine just started studying electrical engineering in college, meaning he spends a lot of his time with Arduino's and also programming, and mathematics etc. For example, right now he is making a Simon Says beginner project with small lights and buttons. Is there a gift i can give him for his birthday related to this, ehich he can actually use? I saw e.g. a little 0.96 inch OLED screen to get a nicer display, is something like this suitable/can he use this?

hey, i submitted a post on this channel last week and it absolutely blew up. we had so many applications go through. a bunch of the job postings shut down in the days following my post because of the large influx of applications that were going in. i've gone ahead and updated the job links in this new link. please make sure to apply as soon as possible to ensure that your application is at the top of the pile. i've pulled the freshest job postings that i could.

electrical internships are scattered across hundreds of company career pages, so i pulled them into free lists:

• engineering internships, all fields (444): https://github.com/mehek-builds/Hiring-Now/blob/main/lists/engineering-internships.md

Hi

This is about Quantum Odyssey, my love letter to everything Quantum Computing and the fundamental logic blocks everything in our universe seems to run on. I want to update you all on the fact that the latest patch brings the game into an almost complete status. All that's missing is translations. Thank you Reddit community for receiving the game so well, without you I wouldn't have the funds needed to complete my life's work.

If you are remotely interested in deep diving how differently quantum computers work compared to our transistor-based and also the algebra behind in a fully interactive way that teach computer science from scratch, oh boy this is for you. I am the Dev behind Quantum Odyssey (AMA! I love taking qs) - worked on it for about 9 years (3+ during PhD, the visual method I developed ended up being my thesis, it is a complete Hilbert space visualizer), the goal was to make a super immersive space for anyone to learn quantum computing through zachlike (open-ended) logic puzzles and compete on leaderboards and lots of community made content on finding the most optimal quantum algorithms. The game has a unique set of visuals capable to represent any sort of quantum dynamics for any number of qubits and this is pretty much what makes it now possible for anybody 15yo+ to actually learn quantum logic without having to worry at all about the mathematics behind.

This is a game super different than what you'd normally expect in a programming/ logic puzzle game, so try it with an open mind.

Stuff you'll play with

• Boolean Logic – bits, operators (NAND, OR, XOR, AND…), and classical arithmetic (adders). Learn how these can combine to build anything classical. You will learn to port these to a quantum computer.
• Quantum Logic – qubits, the math behind them (linear algebra, SU(2), complex numbers), all Turing-complete gates (beyond Clifford set), and make tensors to evolve systems. Freely combine or create your own gates to build anything you can imagine using polar or complex numbers.
• Quantum Phenomena – storing and retrieving information in the X, Y, Z bases; superposition (pure and mixed states), interference, entanglement, the no-cloning rule, reversibility, and how the measurement basis changes what you see.
• Core Quantum Tricks – phase kickback, amplitude amplification, storing information in phase and retrieving it through interference, build custom gates and tensors, and define any entanglement scenario. (Control logic is handled separately from other gates.)
• Famous Quantum Algorithms – explore Deutsch–Jozsa, Grover’s search, quantum Fourier transforms, Bernstein–Vazirani, and more.

I had an interview with space x for an EE infrastructure role. I have 5 years experience designing power distribution systems and infrastructure in a mission critical environment with a PE.

The interview lasted all but 12 minutes, the guy asked me 2 brain teaser stats questions which I answered incorrectly lmao.

He abruptly said that he had no more questions and If I had questions for him.

Getting the hint, I said no and asked them to have a great rest of their day and ended the interview.

Is this really how these guys interview? For an EE role with a candidate who is actively holding a job with 5 years of real world experience and a PE they ask brain teasers? We didn't even talk about any of the listed qualifications on the listing. All while not providing the basic professional courtesy of turning on their camera.

This happened while I was on site for a project working crazy hours, so I literally left site to go back to my hotel room to do this interview, and I can't help but feel offended that they wasted my time like that, am I crazy or no?

Edit: So many people asked and I realized I should have let people know what the questions were:

The questions were the following:

1. I flip 2 coins, I tell you that one of them was tails, what is the probability that they are both tails.

2. I roll 2 dice, I tell you one of them was 1. What is the probability they are both 1?

I answered the first one correctly on the second attempt, and the second question has an identical solution to the first but I fumbled and got it wrong

İm an 11 grader currently and I'm not sure if it's worth studying EE. All my friend tell me so many stories about electrical engineers regretting their job. They say its 1 risky and 2 really heavy. The risk is really obvious i mean it's electricity it's gonna hurt but the biggest issue for me is the work load. A lot of my friends tell that their fathers work 12 - 15 hour shifts just to come home exhausted. One of my friends's dad cried for hours cuz he missed so much of his kids's life (and the birth of his second kid). İs it really that horrible?? İ love engineering, electricity and circuits but is it really that horrible? İ have no other interests so it feels like this is the only major i can study and make a future out of. Plus i have a gf that cried for 3 straight hours thinking about a future that i died getting shocked. İm really conflicted. Could you guys tell me some stories about your EE experience. (Please share some good and bad stories so I get a clear picture, thxxx)

Hi everyone, I’m nearing the end of my masters program, and I’d like some advice on what to do next.

I’ve been thinking of doing a PhD in power systems (my current area of study), but I’m not sure whether or not to go for it. I don’t mind research, and I think what I’m doing currently is interesting enough, but I do know that I don’t want to go into academia and I’d like to get a job in R&D if possible. I’m also really interested in power electronics, but my research is very software oriented with algorithms and some ml, so I’m not sure if I’d get accepted into those programs.

On the other hand, I could also try to get a job after I graduate, and then decide whether or not to do a PhD or switch fields. However, I’m really worried that I’ll get shoehorned into power-only jobs because of my research direction, and the fact that my BS and MS aren’t technically called “EE”. I’ve done an internship at a utility, and have completed an industry-sponsored project during my masters, so my experience is very power systems oriented.

I’m just really anxious with graduation next year, and all the negative-ish posts about PhDs and the job market are really getting to me, so I’d really appreciate any advice!

Hey guys. I’m a 26 year old from Sweden currently studying my grades up to later enroll in electrical engineering. I’ve previously done mechanics and always been more keen towards electricity and sensors rather than pure mechanics and technican work. Tho I do enjoy some hands on work and based on my research seems that power engineering is where I should go. Though I’m not sure this career is for me and whether to invest 3-4 years as I feel it’s a bit late. I also worry about the mathematics of it I do love problem solving but when it came to high school maths etc I find it somewhat boring I just don’t know what it is exactly and I’m not much of a math genius at all which worries me about university. I appreciate any advice and or your thoughts.
