🔍 What is it?
HALO TOUCH is a compact desktop USB hub + round display gadget designed as a DIY multi-function desk companion.
It integrates:
USB 2.0 hub (2×A + 1×C)
TF card reader

Pomodoro timer with haptic feedback

AIDA64 PC hardware monitor
Rotary knob with Surface Dial-style control (Win10+)
All features run in one device driven by a tactile rotary dial and a circular IPS screen.
💡 Why did you make it?
I wanted a single playful desktop gadget that could:
- Expand USB ports
- Show real PC stats
- Act as a timer when working
- Play music when relaxing
- Display photos/animations when idle
- Offer a physical dial similar to Microsoft Surface Dial
Instead of having multiple small devices, I built one all-in-one desk companion that blends functionality, fun, and cyber aesthetics.
