So for a while now I have tried to find an inexpensive way to have a light come on when I hit the record button.
Of course I can have the light come on for me using a control surface, but the folks on the stage want to know when they're being recorded.
This may not be the best way, but it was what I could do with my skills. So I wrote a How-To document on my blog.

I hope someone finds this useful.

Well, it's been nice knowing you all.

I got so obsessed with the M5StickC project that I spent an entire week playing with the source code.

Old Teensy laying around... lots of pins... project box... this is going to spiral out of control.

Seriously though, nicely done.

Nathan,

Well done, you have inspired me to try this project.

I must say the Teensy is a very nice IoT board to work with. Code uploads quickly and loads it up just as fast. I veered off in a different direction and would up making a 4 button MIDI controller with 5 LEDs on PWM control that can be set up as activators. OP's code was pretty paramount in getting an understanding of MIDI coding and the whole hex pitfall when addressing channels.

Since I didn't want to keep running to the basement to test things, I connected my new Teensy box to my laptop and set up rtpMIDI to control my vMix machine remotely. It was super easy to set up, with a latency of 1 ms.

So that inspired me to try another project: eliminate the middleman laptop and use rtpMIDI natively loaded on a WiFi-capable IoT board. $70 USD later, I have LEDs, resistors, buttons, project boxes, and a 5-pack of ESP8266 boards en route.

I opted for the ESP32 based boards for this next project because of the built-in WiFi. If you've seen the $10 wireless tally project on the forum, this is what is at the heart of the device. The downside is that there is no native MIDI over USB support, unlike the Teensy. That's why the tally project code relies on the vMix API versus using MIDI activators. On the flip side, a 5-pack of ESP8266 boards are pretty much the same price as one Teensy LC.

That said, I would not hesitate to buy another Teensy board if needed for another project. But I also wouldn't hesitate to get another ESP32 based board or device. It just depends on your needs for a particular project.

It's pretty awesome to have these boards available and use them to make things to enhance our setups.
