Hi to everyone,
I’m taking inspiration from smart knob of Scottbez1 ( https://youtu.be/ip641WmY4pA?si=L7D79npHyagAS5Vn ) and wanted to share an idea I’m working on. I’d also like to ask for guidance or suggestions, as I’m seeking help in both software and hardware development.
Project Description
My goal is to create a system capable of:
Displaying social media notifications: Showing a preview of notifications from major social platforms (like Instagram, Twitter, etc.) directly on a display by pulling data from my iPhone.
Controlling Spotify: Allowing users to see the currently playing song (title, artist, album cover) and interact with playback (pause, skip tracks, etc.). At the moment, I have just a very basic connection to Spotify’s API.
I would like the this device will be power on with usb-c or small lipo, which can be recharged using usb-c
The device will feature:
A rotary knob for control.
I currently have the following components (I had some research to find something like these components):
ESP32-S3 N16R8: My main microcontroller.
1.28" 240x240 LCD TFT display, maybe something bigger (GC9A01): For showing notifications, Spotify information, etc.
MLX90393ELW-ABA-012-SP magnetic rotary position sensor: For precise position sensing with the rotary knob.
DRV2605L controller for haptic feedback
Different DRV2605LYZFT around knob
Strong Magnet under a 3D printed knob
Areas Where I Need Help
I’d greatly appreciate help on all fronts, including:
Hardware Design:
Optimizing the use of the listed components.
Suggestions for a compact PCB layout and wiring that fits within the cylindrical design.
I’m very motivated to bring this project to life and any insights or guidance you could provide would mean a lot to me.
Thanks so much for taking the time to read this, and I hope to hear your thoughts!
