Living Room Node Upgrade

For over a year now the living room node and La Crosse Gateway has been sitting atop a plastic bin next to my patio slider in a mess of wires.  This is when you know you have too many projects lying around the house.  So this summer I decided to design a PCB with a nodeMCU that will replace both projects and mount atop of a power brick. I went with the nodeMCU since there is power nearby, ease of connecting directly to the MQTT broker, and I can broadcast more often without the power limitations of a battery. This project frees up two RFM12B boards so that they can be used for the other window and the front door.

PCB Battery Clip

Just a small update to the battery powered nodes. Until now I had used a piece of tape to hold the PCB to the battery pack. It was always a pain when changing the batteries or accidentally hitting the node and watching it fall apart. I also wanted to try my hand at Fusion 360, so this seemed like the perfect opportunity.

I still have a lot to learn in using Fusion 360 but I got the job done, um sort of. I had issues extruding the width less than I had initially and I didn't want to start over. So canceling the print worked good enough at the size I wanted.

It came out quite nice. I just need to learn Fusion 360 properly.
