I missed last week’s #onethingaweek. So let’s fix that. Had some time on the train to Cologne last weekend, so I did some work on low power LoRaWAN sensors for the @ttn_munich meetup last Monday.
And this week, I restored an old and rusty chipping hammer. Didn’t take a picture before I started working on it, but here’s the final result with a fresh coat of spray paint. #onethingaweek
