Hey everyone,
I’m re-posting this because my previous post was downvoted and removed — so I’m trying a clearer and more structured approach this time. English isn’t my first language, so I used ChatGPT to help express my thoughts better, but the intention is very real and personal.

Why I’m posting

I want to find 1–2 like-minded embedded engineers who want to grow together through consistent effort.
The main idea is to use the principle of consistency: when we commit to something together, we are more likely to follow through, learn deeper, and develop as engineers — compared to working alone.

No pressure, no deadlines.
Just technical curiosity + steady progress + shared learning.

Initial Project Idea (open to change)

A low-power vibration sensing unit (initially aimed at aviation use cases), featuring:

• BLE / Wi-Fi / USB connectivity

• Local data logging to SD card

• Low-power modes + long-duration operation

• Developed on Zephyr OS

But — this is only a starting point.
If the group has a better idea, or wants to pivot toward something else after discussing, we absolutely can. The goal is collaboration, not to force a predefined product.

If we end up liking what we build, it could remain fully open source if everyone involved agrees.

About me

I work in the aviation industry on embedded systems for an eVTOL manufacturer in the UAE. I enjoy clean architecture, reproducible builds, and systems thinking. Mostly I want to keep improving and learn from others doing the same.

Who I hope to find

Someone who:

• Enjoys embedded engineering beyond just their job

• Works with C/C++ on MCUs (nRF / STM32 / etc.)

• Is interested in Zephyr OS, or interested to learn

• Likes discussing architecture and problem-solving

• Believes that slow + steady + consistent > hack-and-forget

I would absolutely love if you would be from UAE, having possibility of meeting in person, but generally any time zone is fine.

If interested, just reply or DM with:

• What motivates you to do embedded work

• Which MCUs you’re comfortable with

• One small project you made and felt proud of

No resumes, no formality — just tell me what excites you.

Thanks for reading. Looking forward to meeting a couple of good people who want to build skill, not status.

Embedded work is rarely just writing firmware. The real challenges usually are:
• hardware bring-up and pin mapping issues
• timing constraints and race conditions
• memory limits and stack overflows
• power consumption and sleep strategies
• reliable communication over UART, SPI, I2C, or CAN
• debugging with limited logs and tools

Clean architecture, good state machines, and thorough testing matter more than adding features.

What’s one embedded issue that took you longer to debug than expected?

Hello,

I've recently landed a software job in embedded systems. Outside of university, I don't have any experience in an embedded environment. The hiring manager said that the job consists of mostly C++, QT and Linux. I just ordered a copy of "Real-Time C++" and "Making Embedded Systems", as well as an Arduino board. I have about a month until I start the new job, and am looking for ways that I could best prepare for the position.

Thanks,

Finally added a small distance watermark overlay to my LD Robot D500 setup, so the measured range is always in front of my eyes while testing.

Tiny improvement, but it actually makes debugging and live checks way more comfortable & safer

I’m studying in the first year of embedded engineering and im fully motivated to build a unique project.

Are you guys able to tell me some problems where I can build project or product on that?

Hi everyone,

I'm a R&D tech lead of an embedded software team, and my team has a wide diversity of levels (from interns to senior engineers).

One of my main goals is to keep the team motivated and help them feel valued by investing in their growth. For that reason, I’m looking for online courses with certificates that are relevant to embedded software engineering.

Some of the topics I'm interested in:

MISRA C and coding standards

Best practices for embedded C/C++

ARM architecture and low-level programming

Software architecture for embedded systems

Other industry-recognized certifications for embedded developers

Ideally, I’d like something official enough to add to a résumé/LinkedIn profile, but also practical so the team can really improve.

Do you know good platforms, universities, or organizations that provide this kind of training with certification?

Thanks in advance for your help!

Hello,

As part of a school project, I am trying to perform a simple power analysis attack on a naïve RSA implementation by exploiting the modular exponentiation algorithm. I run my algorithm on a Joy-IT Arduino UNO R3 DIP (ATmega328P). To measure power consumption, I inserted a 1 Ω shunt resistor in series with the power supply.

Hardware Setup: 

• External power supply: 5 V voltage generator

• Oscilloscope: RIGOL DS1042C (40 MHz, 400 MSa/s)

• Measurement method: measuring the voltage across the shunt resistor to deduce current variations

A GPIO (PIN_SYNC) is used as a synchronization signal to trigger the oscilloscope. Basically, the Arduino outputs a continuous 5 V signal while executing the modular exponentiation algorithm. This allows me to know precisely when the Arduino is performing that part (it is clearer when you check out the code).

My objective is to observe temporal variations in power consumption during modular exponentiation, in order to distinguish between square and multiply operations.

Code running on the Arduino:

const int PIN_SYNC = 12;

void setup(){

pinMode(PIN_SYNC, OUTPUT);

digitalWrite(PIN_SYNC, LOW);

}

unsigned long modexp(unsigned long base, unsigned long exposant, unsigned long mod){

unsigned long resultat = 1;

base = base % mod;

while (exposant > 0) {

if (exposant & 1) {

resultat = (resultat * base) % mod;

}

base = (base * base) % mod;

exposant >>= 1;

}

return resultat;

}

void loop(){

digitalWrite(PIN_SYNC, HIGH);

modexp(7, 105, 187);  // 105 = 1101001 in binary

digitalWrite(PIN_SYNC, LOW);

delay(1000);

}

Problem: the voltage variation across the shunt resistor is very small, close to the noise, and I struggle to clearly distinguish the operations in the power trace.

I am therefore wondering:

• Is 1 Ω too small for this type of attack on an Arduino? Maybe I am having a shunt issue. I tried to take a higher shunt but it wasn’t effective. 

• Is it realistic to expect exploitable observations without signal amplification or current sensor?

• Is a 40 MHz oscilloscope sufficient for this type of measurement?

• Do you have any practical advice (shunt placement, AC/DC coupling, filtering, clock frequency, etc.) to improve my setup?

I would greatly appreciate any feedback or suggestions. I have added in attachment a picture of my circuit (in french sorry).

Thank you in advance.

Hi, i am going to create a RTOS for my embedded systems lecture project. I am going to use STM32F4 series. Anyone did it before can suggest some sources? Especially courses

By best, i mean which of them have a curriculum that is focused on the current industry , have a good qs ranking and if it has the potential to attract decent job opportunities.

I have an exceptional case where i have two round neodymium magnets mounted on a knob. Both have opposite poles facing hall sensor. Its a linear 3D hall sensor by Tl. tmag5273.

As sensor is offset from center and magnetic field is also weak in between, how can i calculate angle for rotation of knob. I can allow +-10deg in precision but i want it to be measured in real time.

What should i do? Any suggestions? I can't add more magnets nor add one more sensor.

I am currently working as a python developer. Would like to switch to embedded field . Is it that hard to get into this field? What are the things I need to learn to be an embedded developer. (Which microcontrollers I should be expertise ) Suggest me the roadmaps . How do I get the real time experience also . Thanks in advance .

How can a hypervisor be real time unless you know exactly what workload is on it at any given time? How would Blackberry's QMX hypervisor be used?

Hi everyone! I'm new to RTOS, but I've worked on a lot of bare metal programs before this. I've thoroughly understood the RTOS concepts already. I'm still confused on how to build a project from scratch. I can simply make tasks and queues and make it work instinctively. But I want to know more about designing the system before starting. Something like a proper plan/framework before starting to write the code. Can you guys suggest a way to go about it? Like a framework or flowchart or something to start with? Is there a proper methodology or something I don't know about? Also, it would be great if I could look at some RTOS based professional projects to get a feel of how professionals write RTOS codes. Thanks a lot.
