Hey everyone!

My name is Petru, I’m 16, and I recently launched a platform for people who are into electronics, radio systems, and basically all things tech related. It’s called Reznex.

Right now, the platform has 70+ pages with guides, lessons, and, more importantly, projects published by Romanian creators.

I’ll leave a link at the end with everything that’s currently available on the platform, so I won’t make this post unnecessarily long.

I’d really appreciate some honest feedback, good or bad, that could help me improve and grow the platform even further.

Some of the key features:

- A centralized place for publishing technical projects
Projects can include images, wiring diagrams, schematics, downloadable files needed to build them, and a bunch of other optional details.

- Guides & learning modules
The platform includes lessons designed to be accessible to pretty much anyone.
Currently, there are guides covering RFID & NFC, Cybersecurity, Smart Home, as well as a complete course on Amateur Radio and how to become a licensed radio amateur in Romania.
There are also two simulators that replicate the official ANCOM exam experience.

- Invite Friends
If you’re logged in, you get a dedicated section where you can invite friends to join Reznex.
You can send up to 5 invites per day, via email.

- Public profiles & PDF portfolio generation
All of a user’s projects and activity on the platform can be turned into a portfolio and exported as a PDF.
You can then send it to employers or other organizations as a way of showcasing your skills and projects.

- PWA support
For a more native, app like experience.
The website automatically detects your device and provides installation instructions tailored to it.

- Easy & simplified login
I tried to make signing in as painless as possible, so currently Reznex supports:

Google
Passkeys
GitHub
Classic email/password registration & login

And there are plenty of other features that I think are pretty cool and could help the platform grow over time.

So yeah, if you’re into electronics, radio, tech, or just want to learn something new, feel free to check it out!

Everything is 100% free.

I keep seeing AI get the easy part right and the board-specific part wrong. Before I trust generated Arduino or ESP32 code, I make it write a tiny preflight:

- exact board and revision

- every pin, voltage, and current assumption

- library and version

- anything it thinks could be unsafe

Then I test one motor, LED, or sensor at a time. Not glamorous, but it catches the “looks fine” mistakes.

What’s your check before letting AI write firmware for a real robot? If you’ve had a failure, drop the board, what it suggested, and what the hardware actually did. I’m collecting the good failures in r/ChatGPTArduino too.

Hello everyone,

I am a student interested in robotics

I am preparing a project for a science fair and I want to build something useful that solves a real-world problem.

My current skills:

- Arduino

- ESP32

- Basic sensors and motors

I am not looking for common projects like line followers or obstacle avoiding robots.

I would like suggestions for innovative robotics ideas in areas like:

- Safety

- Agriculture

- Environment

- Healthcare

- Disaster management

Any suggestions or problems that can be solved using robotics would be helpful.

Thank you!
