Great! Do you have any ESP-01 modules and the means to program them?
Here is a link to the manual for ESPixelStick. The hardware part will be irrelevant but the programming and usage information applies. You are not allowed to view links.

The link to the firmware is in the manual.
Finally, here is a link to the board on OSH Park

EDIT:
Lastly, if you want to try it right away, I can send you a board that needs a small modification. That is what I am currently using. The first design I made used the ESP TXD pin to send DMX data. ESPixelStick uses GPIO2.
Great job. I might be interested to give it a try for the next season.
I keep my 4 LEs away from the elements; They are mounted on a board next to each other inside the house and are daisy chained together with cat 5. From there, I run cables to the lights outside. Keeping the same layout I assume only the first LE would have to become wireless and keep the daisy chain as it is. Is that correct?
I have never bought from OSH Park before. Can you only get 1 or 2 boards from them or do you have to buy in larger quantities? Don't really want to get into etching my own board (yet).
