What can you do in a rainy evening when you go to your hackerspace ?
Take a NoteRF V2 PCB, a GPS, a battery and you can make a lora GPS tracker !
Solder the PCB
Hand solder it or for lazy guys like me, order a $5 stencil from OSH Stencil.
Prepare the rig, apply solder cream and place components.
Time to reflow in a hot plate, then visual and electrical inspection.
Use the pogo-pin rig to easily burn the Arduino bootloader into the ATMega, verify it.
Solder GPS and battery
Solder the GPS, the battery, flash the code and another time: test it !
Thanks to Node-Red and OpenStreetMap, we can easily grab data from LoraWAN operator, decode and display it on a map.
Make a nice box
We now have a battery operated GPS tracker... what about putting everything in a box ?
As I use upcycled 18650 lithium elements, the battery is by far bigger than the PCB + GPS, so I decided to design two compartments inside the box. Some lasercut after it is all working !!!
Also, even if it was not planned, the box sound more like a locomotive than a gps tracker, so back to the laser cutter to make four little circles and... finish product with a fun design !
I Even have some time left for a beer :p
