Heltec ESP32 LoRa outdoor case with sunlight visor now with in visor aiming slots

For survey and Lora research. The visor shades the screen, even in bright sunlight. During nighttime it limits screen light to a very small viewing angle, so nearly no light diffusion or glare. This little makeshift was very helpful in open fields and at sea.

Features: 

• For Heltec Lora 32 Wifi boards (V2 and V3)

• Screen view in bright sunlight over most angles to the sun, even reflective ones

• Display illuminated aiming slots for directional alignment with objects in the field.

• Use O-rings or tape to secure the LoRa board, antenna, and visor together.

• Antenna hex-nut anti-twist (3D printed D-cutout is less reliable )

• Hexnut anti-twist offers more options for antenna connector orientation

• Header cutouts  

• Battery connector access

• USB connector access (for power and logging)

• ! Not waterproof, not for standalone usage (risk in rain, fog snow etc.)

In field  report:

• Operated while connected to a smartphone via USB

• Power supply/serial connecion: Android OTG

• Logging app: serial USB terminal, Kai Morich you did a great job

• Case hold together by two o-rings around case parts (tape will work too)

• Aiming slots were more helpful than expected

• Black case color works best (paint aiming slots white if needed)  

• Pretty good night and day visibility
