This is very cool. I imagine a firefly might consider it to be in the uncanny valley of cute but unconvincing firefly simulations.

It's fascinating to see the successful use of micro-controllers to create lush, organic experiences. A teledildonics boom has been predicted for years, but this kind of demo makes me think that it's going to happen any day.

Ah, reminds me of the old stuff this guy used to do; specifically the section named "fireflys"[sic]: https://home.comcast.net/~botronics/

I actually made this! The hardest thing was to hand-solder the wires onto the SMT LED.

I tried doing this exact project for table decorations for my wedding reception. As it turns out, this project fell to the bottom of the to-do list and never got completed. Anybody need some parts??

Instead of surface mounting, let the LEDs dangle, and introduce a bit of current from air flow or a mineral oil fill.
