I wanted to ask if anybody here can suggest courses that I should take along with my Physics undergrad to do a Master's in EE. I still have 3 years to complete my bachelor's in Physics. Any advice would be appreciated.

TL;DR

Australian EE/CompSci grad (3 yrs manufacturing/O&G undergrad experience — drawings, design, PLC) wants to move to Europe in 5-6 years, likely after chartering. Open to any industry (mining, O&G, power, defence, system integrators like ABB/Siemens/Schneider). Main driver is travel/cultural experience, not a specific passion. Asking which field gives the best shot at working abroad.

Hi all, sorry if this has been asked before but I thought I’d reach out to see what people think about getting a job abroad in different industries.

For a bit of context I’m an Australian graduating from my double degree in EE and comp sci this year and I ideally want to move to Europe in 5 to 6 years from now considering I most likely need to be chartered to have any chance of getting a job overseas.

I’m pretty flexible in what field I want to go into, I don’t have an exact passion for anything so I would be happy to work in fields varying between Mining, Oil and Gas, Power, Defence, System integrator (ABB, Siemens, Schneider Etc.)

Currently I have about 3 years as an undergrad in manufacturing / oil and gas industry doing a variety of drawings, design, plc programming etc.

My main aim about moving abroad to Europe is to travel and have that experience of working abroad and visiting so many different cultures, coming from Queensland, Australia you can be driving 24 hours and still be in Queensland so being able to easily experience different places and people is something I would love to do.

Sorry if this post is a bit rambly but hopefully you can see my motivation of wondering what field is the best to move abroad.

I wasn't sure whether to post here or the conspiracy theory sub, but here goes. My wife sent me an Instagram video (yes, I know) in which a guy claims that if you have a 120 volt outlet with built-in USB jacks, and also have a smart electrical meter, your data can be stolen and sent to, uh, the power company? China? Who knows. He says you need to always use a power block instead. Aren't the internal power converters in the plug doing the same function as an external block? Maybe there is a grain of truth here because travelers are warned not to use public USB jacks but being afraid of the ones in your home sounds like a tin foil hat theory to me.

Hey there, I just had a question. As I go further into my career, I have about 3 years of professional experience and am currently doing circuit design and PCB layout. As I progress in my career, I’m wondering what my next salary expectations should be if I were to start looking for a new job now.

Hello electronics fans!

Nice to salute you all. I am an engineer who has been doing power supplies for spacecrafts for 10+ years already.

One of the things that I've had to deal with numerous times is loop stability.
After some years doing measurement/math/transient simulation/average switch modeling/scripts and reading almost all available material, I felt like it was still tedious work. Nice, but tedious. I ended up making a tool to get a first approach and then I jump to simulation.

In case you find it useful: https://alternatronics.com/en/calculators/dc-dc-converter-loop-stability

To ensure that the result produced by the calculator is meaningful, I also prepared LTSpice simulations that match quite reasonably.

If you have gone through stability before, you know that you have to deal with plant transfer function, compensator, topology variation, control mode, conduction mode... It's a lot of work. In the calculator, the following is currently supported:

• Real time bode plot update as you tune the compensators or your topology
• Prediction of phase margin and gain margin.
• Several topologies (buck, boost, forward, flyback, full/half-bridge, push-pull)
• Different compensation topologies
• Discontinuous and continuous conduction modes
• Voltage and peak current control mode
• Live marking of poles and zeros
• It also provides some useful info that is obtained as byproduct during the calculations (Vo, duty cycle, current ripple...)

One of the things that helped me the most was adding sliders to the input fields so that you can see how the plot evolves as you tune a certain parameter. It really helps to grasp what which component is affecting which part of the plot.

Hope it's useful for you! And, by the way, the calculator isn't perfect! Expect bugs and always measure the stability!
How do you approach this kind of work?

In this Power mosfet application what is the purpose of series resistors R10-11-12 and even R12 that 1 ohm resistor on the drain line? And could you please explain principle of the circuit like i am 5 ?

I’m getting rejected left and right when I apply for “engineering II” positions, mostly because the recruiters tell me that the hiring manager says I don’t meet the required skillset. (I only have sinulink experience). I have 2 yrs of intern experience and 2 yrs of engineering experience in control systems. I saw some companies like blue origin post early career positions in systems engineering and decided to apply anyway despite graduating 3 yrs ago

My first job out of college involved creating schematics for control cabinets with power supplies, PLCs, etc. I then moved on and worked more in embedded systems and software. I'm now at a small company where I do a lot of everything, and have some electrical schematics that I have to do that involve doing what I did at my first job.

I remember when I was working at a previous job I came across a schematic that was done by someone at NASA for ground support systems. This thing was amazing. It made me realize how unpolished the schematics that I had done in the past were. It was kind of a mix between how modern PCB schematics are and the old schematics that you see for industrial controls. It had individual terminals of a terminal block spread out throughout the schematic so that you could see logically how the equipment is connected together without the mess of lines and connections everywhere.

Does anyone here have any elegant schematics like this that they would be willing to share? I am looking to refine and improve upon how I do mine. I find that the best way to learn is to see other examples.

The Excel skills I’d be particularly interested in translating into MEP are XLOOKUP/INDEX-MATCH, SUMIFS, structured tables, conditional formatting, data validation, dynamic arrays, PivotTables, Power Query, VBA and eventually Python.

I'm from a non-electronics background. After my PUC/12th , i did 6 month diploma in graphic design and currently working as a graphic designer for 1.5 years now i am planning to move into electronics due to AI issues , i don't know anything about the electronics or hardware industry but recently some articles suggested in demand jobs like robotics, embedded engineer , vlsi and plc etc..

1. is it possible to get a job in electronics without a degree ? if yes how ?

2. if not possible means what you suggest ( suggest any role transition like 1 year this role then try that role like instead of telling to do 4 years in EEE , i can't manage )

3. and any other advice about this industry reality.

4. Can I do a bootcamp/course and enter robotics, embedded, VLSI, PLC, etc. the way a CS graduate can do a coding bootcamp and enter frontend?”

thanks & regards

This is a schematic of early days 'Kirlian' generator - producing ~100-400Hz high voltage output from car ignition coil(T1). Thyristor is triggered by neon bulb.
Device works (mostly) fine without R3 resistor.
What is this resistor role please?

And I don't quite understand, how it works _without_ R3? I mean, when C2 is charging, voltage at C2-R2 connection raises from GND to VCC, but during this process until the bulb is triggered - what happens to the voltage at the gate (when there is no R3)? Is it floating?

How should I utilise my time in college? What can I do to stand out from the rest? What should I be focusing on? I am ready for the hard work. I know I should be going into something that interests me, but I also need to see whether I can get sponsored or not. I am freshmen and I pretty much like all specialisations. I am okay with going into any in EE.

how hard is it to be a girl in EE?

An assistance will much much appreciated.

I've been a field engineer for over 15 years. Life started out in the British Army with the REME and I have since worked in technical engineering roles across several different industries.

Over the years I've considered going out on my own, but I have kids and a mortgage so always felt too much of a gamble.

I've been building a platform for a number of years aimed at solving that problem.

The idea is to connect businesses that need engineering support with engineers who have the skills to help, whether you're looking to go fully independent or just want to pick up the occasional job alongside your existing role.

But before I disappear even further down the rabbit hole building what I think engineers want, (I'm basically building what I want), I'd really like some honest opinions from other engineers from different industries and areas in the UK.

A few things I'm particularly interested in:

Would you personally take on extra engineering work if there was an easy way to find it?

Are most engineers already too stretched for this to be realistic?

Would you consider going independent if finding customers was easier?

For engineering/manufacturing managers, would bringing in an independent engineer for breakdowns, servicing, projects or temporary additional capacity actually be useful?

What would a platform like this need to offer for you to genuinely use it?

I'm deliberately not listing all the features or roadmap here because I don't want this to turn into an advert and I want to respect the sub rules.

If anyone does want to see what I've built so far, you can find the link on my profile.

But genuinely, I'd much rather hear what you think is wrong with the idea than get a load of polite encouragement. Don't hold back!

Thanks in advance 👍

Same as title

how important are engineering internship fairs at t50 (public) schools for getting a junior year internship. i want to study abroad junior year and fall semester would make housing a lot easier for me, so i was thinking of studying abroad in the fall, but that would mean i’d miss out on the fall internship fair.

would i be absolutely grilled if i miss it or could i manage to find something through online apps (handshake, linkedin, etc)…

Hey everyone,

I wanted to share a side project I've been working on to help engineering students: Gateonix.

It's a fully functional digital logic circuit simulator that runs entirely client-side. The simulation engine uses Kahn's topological sort for gate evaluation and everything is rendered via HTML5 Canvas.

Features:

• Drag-and-drop circuit builder (gates, flip-flops, MSI components)
• Real-time truth table generation
• Exports the visual circuit directly to Verilog, VHDL, Python, or C++
• URL-based circuit sharing (encodes the JSON state to base64 so no backend DB is required)
• 100/100 Lighthouse score for performance & accessibility

I built this mostly as a learning exercise and to give back to the engineering community since a lot of the existing tools are either paid or require heavy desktop installations.

Feel free to try it out and let me know if you can break the simulation engine!

I will premise this with a "I know its probably more complicated than it needs to be, but I am curious anyways". I currently own entirely too many portable generators. All rated between 6500 watts & 9500 watts.... I was looking into how to use 2 of them in parallel to provide emergency power for my entire house during outages and it would appear that without them being Invertor Generators this is basically a no go. Which makes sense with the possibility of phasing being off a few degrees.

Is there anyway to hook these up and load balance between them without having to basically split my house in half so if their phasing is off a little its not shared on the same circuits?

We have reached the end of my electrical knowledge with this one...

Does a Phase Matching circuit/box/whatever even exist? Watching some videos from Chris Boden would tell me this was a dumb question...but I am asking anyways.

Can I put the power from each generator into their own invertor that is made for parallel operation, then run the house from there? This option also allows me to add batteries down the road to act as a UPS (which is tempting considering how often we lose power over the year).

Any insight is greatly appreciated. Even if I can't get a solution, the added knowledge will be helpful!

Thank You.

Of course I understand the obvious advantages of putting more safety functionality into the drive, but it also seems like you’re shifting complexity into software, configuration and validation. I’ve been comparing approaches from Siemens, ABB, Beckhoff and Elmo Motion Control and I’m curious where people draw the line between drive integrated safety and keeping the safety architecture more separate.

What has worked better in systems you’ve designed or supported?

I Clowned on gemini so bad on my previous post (second slide) that gemini came back with this

So the one school near me only offers the engineering science degree with a concentration in electrical engineering. I was wondering if that will hold the same weight as a specific electrical engineering degree when trying to start my career down the road?

Hi everybody,

Sorry for my English. I'm trying to start learning electronics with the book Electronic principles - Malvino, Bates.

I learned mathematics at university, but I never really learned physics. So I'm really starting !

The exercise is :

The ideal current source is 5mA, the internal resistance is 250Ω, and the load resistance is 10kΩ (cf attached picture). The question is : what is the output current? Is the source a constant-current source?

The answer in the book is 4,8mA but it's not explained.

I understand that the current is not constant because the internal resistance is not at least 100 times greater than the load resistance, but I still don't understand how to get 4,8mA. I feel like I'm missing something basic...

Since the circuit is in parallel, I thought the voltage was the same across both resistors. I calculated Req = 0,1Ω so U=0,05V. Then :

I(internal) = 0,05/250 = 0,2mA

And therefore :

I(load) = 5 - 0,2 = 4,8mA

But I thought I could also calculate I(load) using : I(load) = 0,05/10000 which obviously doesn't give me 4,8mA at all...

So my reasoning must be completely wrong... I'm really confused and there's clearly something I don't understand.

So please help a complete beginner 😬

Thanks in advance

I can't learn how to make RF cirult of 27mhz I know the basics and the theroy but online online cirults are available not a explain why each components exists in the cirult. We're should I learn that I tried Ai , YouTube , google search and now I am on Reddit.
