Description

Something like Iron man helmet but can drive with simple arduino
Raspberry pi zero, PICO and more

- Driven with simple SPI interface
- Helmet cost about 30$ displays 10$
- 2x SPI IPS display 240x240 ST7789
- Easy drive with #samd21 #rp2040 #raspberrypi #ESP32
- no complicated HDMI
- beautiful and clear image in all you view
- LOW power about 60mA including SAMD21 MCU
- parallel or separated (for 3D) display driving
- USB OTG

YOU CAN TYPE ON KEYBOARD AND DIRECT READ MESSAGES :D

-module also have prepared LoRa radio for sending/receiving messages and GPS

TODO:
- Adjustable distance between displays (flex cable or solder bridge)
- Test on Raspbery pi zero
- select nice 8pin cable/connector etc. USB-C with custom pinout

Details

How it wear:

Against google glasses little bigger :D

Entry video:

First version driven with Armabrain SAMD21 core, this version works standalone with USB-OTG keyboard
and long range radio LoRa for sending/receiving messages

new version with raw displays only
