An projection glass that display realtime crypto price using Seeed Studio XIAO ESP32C3.
This is not an original project. The main inspiration for this project comes from Alain's Projects. However, I change some part, e.g. I use Fresnel lens instead of magnifying glass; use Seeed Studio XIAO ESP32C3 instead of Arduino Pro Micro.
Display BTC, ETH, BNB realtime price.

I use Seeed Studio XIAO ESP32C3. It's cheaper than Arduino nano/mini pro, have built-in bluetooth + Wi-Fi module and it'd super small.
I use 0.96 inch oled display.
I use 45mm * 45 mm * 2mm mirror.
And glass cutter without kerosene.
I use Fresnel lens with 10cm focal.
