I'm just a simple man who loves electronics. I live in Spain and I've studied electronic engineering in UB, University of Barcelona. ELECTRONOOBS all started as a simple Instagram account where I was posting all my daily projects and homework. I soon started working on this webpage where I’m currently posting new tutorials every day. As you can see, there is a bit of everything. Electronics with Arduino, basic circuits, robotics, 3D printing and so on.

Later I’ve made my first YouTube channel called ELECTRONOOBS as well. Next, I’ve made my second channel just for Spanish projects and blogs. I hope that you will enjoy my webpage and everything that I do. You can check my Patreon page and help my projects. ELECTRONOOBS also has a Q&A forum page where you could post your question and me or anyone else could answer it. Thank you very much!

See how to mount the circuit, read the signal from the PIR sensor, detect 0 cross of 220V AC signal, then create a firing pulse to the TRIAC gate and control the power to the light bulb. Read more

This is a very simple project that uses the Adafruid library to control a RGB adressable LED strip that will eb inside of a Daft punk Helmet. See the code, STL files ane everything you need. Read more

I've been working on an Arduino based smartwatch that could show time, date, alarm, temperature, connect to a smartphone via Bluetooth and show notifications. Read more

Finally, the board works perfect. So I could make a 3D design for the case and this is a final product that could end up on Kickstarter. It is a very cheap project, around 15$ for all the parts. Read more

This is a very basic tutorial and there are already a lot of guides on how make something like this. Read more

This board use a 433Mhz radio connection and an ATTINY 85 chip, so everything is very simple. It has only 4 “digital” channels so we can’t really use it with drones for example... Read more

FPGA tutorial on how to implement UART connection in Verilog. Example with the HC05 bluetooth module. Read more

New tutorial on how to use a DLP 3D printer to etch high details PCB using UV sensitive film and UV light. Read more

I've made some "nixie" tubes. These are actually 7 segments displays made with filament LEDs but placed in a plastic bottle so it will have a more vintage nixie look. Read more

DIY portable soldering iron V3.0

Now we can solder the remaining components such as the vibration sensor and the side push buttons. The board I've made didn't had the wings pads for the buttons, that's why I've put some hot hlue behind the buttons. But the final GERBER file has the wing pads for the buttons so solder those as well. Next we solder the clips for the T12 tip. Make sure the clips are on the bottom side. Read more

Arduino brushed motor DRONE tutorial

Go step by step and build the ultra low cost drone using some wood sticks, the Arduino, the MPU6050, NRF24 radio modules, the old radio transmitter and last but not least, the cheap brushed motors.. Read more
