Picoballoon - DEVLOG #3🎈

Hi!

Yesterday I’ve finished the power and radio system.

Also decided to use foam cover instead of the 3D printed one.
Foam one weighs only about 9 grams and has better insulation for the components.

Testing the LoRaWAN connection
I took a bus to the nearest TTN gateway. With the first testing code helped me Claude a lot, because my coding skills in micropython are pretty poor at this time. :D
I will lock myself in my room until I’m capable of writing it. (because AI micropython code pretty much screwed up the testing) - The radio was left on the default private-network sync word (0x12) instead of TTN’s public sync word (0x34). So the gateway never had a chance to decode it.

Instead got some basic MAC data from the gateway, at least i know the radio does work.

I did look kinda funny with the laptop on the street tho. :)
