Someone mentioned it on my repo a few months back. I think the space constraints would make it very challenging to make a drop-in replacement that fits in the original housing.

Of course, with a new housing, the sky is the limit :) But that wasn't the main design goal.

And bare esp8266 is about the size of my thumbnail. They're tiny. I'm not personally aware of a smaller Arduino.

Regardless, really cool project. Thanks for putting it on github!

Some kind of networking/bluetooth stack would be very useful.
