Use Wio Terminal as a serial logger

When making IoT development, you need to debug on the Field. I’ve been using some serial logger to store information and analyze them after (I’ll post something about it once a day). But sometime you want to watch it in real time. So you need a small terminal you can easily transport with you. Smartphone could be cool and I’m sure we can hack something fun with a BLE connectivity. By the way, what I had in stock for doing a such thing was a Wio Terminal from Seeed.

This device is an Arduino compatible solution including a LCD screen 320×200, some interesting embedded sensors and a lot of IO to play with. The only bad point for me and the design I want to do is the absence of internal battery so you need to power it a different way.

What I need is just a Serial line to print on the LCD screen all what my IoT device want to share. Let see how I did make it.

Bird watcher with balena Fin (or RaspberryPi)

I wanted to play with my Balena Fin and make the famous Bird-Watcher but unfortunately, the documentation is a bit light to be able to reproduce it simply. So finally, I’ve decided to make a post about this project and the different steps to make it working.

The project is now deployed on a tree at home and waiting for some birds to be photographed.

LoRaWan solar gateway monitoring

In a previous post, I’ve been introduce my home made LoRaWan solar powered outdoor gateway. I’ve been investigating on the minimal hardware to make it running and reach some interesting result in my garden ;). Now it’s time to deploy the gateway on the field (basically on a roof top) and this means I’ll not be able to continue to learn what how it evolves over time.

For this reason, I’ve made a small project to monitor the main elements I want to track about this gateway:

  • Battery Voltage
  • Battery in & out power
  • 5V powering availability
  • Temperature

For this I’ve selected a simple and LoRaWan all-included Arduino platform I already detailed in a previous post: the LoRa Radio Node. Let’s detail this project now available on github.
