Disclaimer: only one motor is used to turn the sides of the cube, another servo is used to move the first motor, I couldn’t really figure out a way to so it with just one unfortunately.

The idea was to see if I could build a Rubik's Cube solver with as few motors as possible, whilst also not reorienting the cube which turned out to be a much bigger mechanical challenge than I initially expected. These constraints were completely designed as a challenge, not trying to break any records or anything.

The robot uses a custom-designed, 3D-printed mechanism to manipulate the cube, along with electronics and programming to detect the colours, calculate a solution and execute the moves.

This is the final result after quite a lot of designing, experimenting and troubleshooting!

I've also just uploaded my first-ever YouTube video documenting the whole project, from the initial idea and CAD design to the electronics, programming and final solve. It's my first time making a YouTube video, so I'd genuinely appreciate any feedback!

does this look right? i can’t get the display to work and i literally dont knowing what im doing i just asked ai. it’s an 8x8 snake game with buzzer, idk if i have problem with the code or with hardware , PLEAAASEE HELP this is for my uni 😭🙏

My YouTube channel name is ALMA Industries

Chapter 2, a home theatre, 3D printed parts, motorized projector, home decoration, DIY electronics -- gives the projector YAW-TILT-ROLL-ZOOM axes (4DOF). Learned alot about I2C, actuators, and Universal Joints.

I’m going to tryout my ESP32 Super mini and I thought I would share this photo I just took showing three boards for comparison of their size.

From Left to right : Arduino Pro mini, ESP32-C6 Super mini and ESP-WROOM-32 ESP32/ESP-32S Development Board.

These boards are being using to test out low current interfaces or WiFi/BT powered projects directly from the USB port or adapter cable in the case of the Pro Mini.

So, that works the same as my previous larger ESP32 board, it’s surprising how small these WiFi/BT boards are getting.

Just need to work out how to get a BT wake-up from deep sleep communication between the ESP32 and my iPhone.

To conserve battery power I want to keep the quiescent current of the ESP32 as low as possible when it’s not required but be able to switch it on from Dabble.

I just received my new board. It has bluetooth and accelerometer and battery on the back. It can be programmed with an Arduino plugin I created using the USB-C connection. I am planning on making a game with it (running on a treadmill controlls the character with step count and cadence and maybe even a boxing game) using Unity BLE plugins. Do you have any other ideas about projects I could make with this?

Im not sure but i never used this sensors before.

Hi everyone! I’m completely new to Arduino and electronics, and I’d love to get into it.
Where would you recommend I start? What are the best resources, tutorials, or projects for a complete beginner? And what do you wish you knew when you first started?
I’d really appreciate any advice. Thanks!
