To aid in finding my current grid square and compass bearing. I have build a portable unit to display the requested information derived from a GPS signal and a digital compass.
The unit constructed from the following items:
- DETA 108x108x76mm PVC Conduit Box.
- 20×4 LCD.
- AVR ATMEGA Microcontroller.
- CJMCU-GPS-HMC5883L Unit – Contains.
- UBOX NEO-6M GPS Unit.
- HMC5883L Digital compass.
- Battery and charger.
I started by cutting a front panel using my CNC using some 2-Plex.
Once cut I assembled the enclosure and LCD.
More to follow.
