This, but it's a Meshtastic board powered by photovoltaic fletching so I can fire them high into trees to create a rogue comms network

nrf52840 I presume. ESP32 needs a bit too much battery for a bow.

I should probably read into them before the world goes belly up. At the moment, I'm only somewhat knowledgeable about ESP and Arduino.

It's easy. Just get a nrf based device like the lil go echo and you are set.

You can flash all variants of Lora network software and it has a built-in rink display if you need to read messages without a phone and also battery and charging.

Thanks 💖

But I meant programming these myself, I'm a sucker for that stuff 😅

Ooof deepdive. It ends for ne with avr cli and somebody else's code.

[–] SeductiveTortoise@piefed.social 1 points 2 months ago

No worries. I'm too busy with other stuff anyway. ESP32 I use all the time and they're fine but hungry. I would like to create a battery operated sensor. But that is, I guess, out of the question for the ESP.

... one more thing on my "to check list" that I'll never complete!

let me help you rethink your design. the arrowhead is going to take too hard an impact for pcb. you want to put all that in the shaft near the fletching so you don't have to run as much wire.
