Almost finished my own TTN Mapper! A number of case revisions and a whole new LoRaWAN stack (RadioLib) later, I could actually start mapping yesterday! Cycling around town, taking the train to university… all working well!
Inspired by the Adeunis FTD but that thing is way too expensive for personal use and I thought I could do better 
Also designing an adapter so I can click it on my bicycle for even easier mapping…
See this link for some great mapping results!
