Testing routes from central Seattle down to Tacoma is shockingly stable.

Testing a route from mobile radio through the cougar mountain repeater to a node in Tacoma and back again.

My handheld has an extremely strong signal reception from Cougar Mt as does the Tacoma node. My uplink to cougar is weak, but seemed to work well enough. — Testing a route from mobile radio through the cougar mountain repeater to a node in Tacoma and back again.

Meshcore is working well enough in Seattle that now adoption is the largest issue to having a more robust LoRa mesh network.

So if you're in the PNW area and want to build a solid handheld LoRa radio to try out meshcore I've made a bill of materials for my go to portable build LoRa plans.

Also have you seen this neat little #OpenSCAD program that you give it a list of screw hole locations and it automatically generates a 3D printable PCB mounting frame baseplate with standoffs? It's really slick!

Jamming everything inside was a little tight. Maybe I'll rebuild it and see if I can get things to fit better. #Arduino #ESP32 #electronics #maker

A higher angle showing how everything barely fits

The box is the same form factor as the temperature controller I slapped together at Christmas. The back panel is nearly the same, but the cord socket has a built-in switch & fuse. #Arduino #ESP32 #electronics #maker

Rear showing the same outlet and power cord configuration, with the only real difference being the upper yellow one has a nicer cord socket with integrated switch & fuse.

Sides of the two boxes showing they are pretty much the same size with screw locations in roughly the same location

Got my little "fan controller" built. It's just an ESP32 with a relay board controlling a couple of outlets. It subscribes to MQTT and receives commands and sends status. Buttons to toggle outlet state, LEDs above buttons to indicate state. LEDs along right are power, WiFi connected, MQTT connected.

Just before bed slapped together Python script that runs on my server to monitor bedroom temp and outdoor temp and keep room comfortable without A/C. It worked!

Outlet controller with yellow face plate, blue & white LEDs, and blue buttons, with fans in background. Blue LEDs are on indicating everything is powered up and fans are running.

Of course by the time I almost got it working the temperatures were already within 5 degrees. #Pushover #Arduino #ESP32 #electronics #maker

Time to cobble together a quick & dirty Python script that can monitor the outdoor temperature and the indoor temperature and when the difference reaches 5 degrees have it send a #Pushover notification to my phone to turn off the whole house fan. #Arduino #ESP32 #electronics #maker
