Dev boards are getting fancy...

I bought one of these Waveshare ESP32-H2-DEV-KIT-N4 boards to help debug a client Thread project.

For $6AU I saw a single USB port and expected it'd use the ESP32 internal USB Serial/JTAG Peripheral feature.

Nope... this thing has a USB hub chip on it, and a dedicated USB/serial interface chip, so it shows up as two USB serial ports!

Woot, just finished implementing my first GitHub / Forgejo Actions which allows me to programmatically push meshcore builds to my radios on the roof from the comfort of my browser.

It currently only supports deploying to esp32s3 based LoRa devices so far.

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

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.

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!

#Arduino#ESP32 #electronics #maker

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.

So happy to see the project that I have been in love with and contributing to for the last several years getting so much attention.

If you work with ESP32 or RPi Pico devices and want a development platform built with fault tolerance and concurrency at it鈥檚 heart that allows you to write sophisticated applications with very little code AtomVM might be just what you are looking for.

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

Writing my first meshcore PR 馃馃徔

It's still a work-in progress, but having a lot of fun learning this code base!

Idea for this PR is to add a network bridge mode for repeaters.

This will let you take multiple LoRa radios, setup meshcore repeater firmware and listen on any number of channels or with different antenna setups and bridge the routing across those different channels with a shared Wifi link(the two dotted white boxes).

I've tested it for a few days and it's pretty amazing to see meshcore automatically finding bridged routes.

Complex repeater topology. 

Typical user companion radios are shown as circles. Repeaters are shown as diamonds. The colors of the nodes indicate their frequency.

Rapidly moving my meshtastic nodes over to meshcore 馃馃徔

Going very smoothly so far. Meshcore is notably very fast at message delivery and delivery confirmations back to the sender.

Thinking I'll leave my primary meshtastic infrastructure nodes up and build meshcore nodes to deploy next to them so as the network matures I can do head to head comparisons.

MeshCore has released their code today.

I've read most of the code and this is fairly early, limited docs, no mobile app and limited hardware testing.

That being said the over the air protocol+routing looks excellent. The code is well designed and fairly slim. The security posture is good and designed in from the start.

They get so much right in so little code. I even think I could make this messtastic compatible faster than they can improve.
