Picoballoon - DEVLOG #2 🎈

Hello!

These 2 hours i’ve been working on the solar power system, antenas, and last devlog.

Why the solar system again? Because i screwed up first time making it. But nothing big. I have accidentally put the 2 supercapaticors on top of each other without isolation.

It was taking down energy so much, that at the end of the circuit was about 0.2 V, instead of 5V.
Now i soldered them next to each other. Everything is well isolated from now.
Still need to wire them to the solar panel, but that will be easy.

Also wired two 7.5 cm copper antennas on the rf module. The 7.5 cm antenna length is a compromise across all three LoRaWAN frequency bands (EU868, US915, and AS923) 📡

Now the dilemma

Can i count time spent on the devlogs/repo as a project time? If you have any idea, please let me know. :)
