Sorry this took so long. I've finally made a few dozen kits. I will be selling them for $15 including an ESP8266 chip, or $10 without.
Here are some instructions for building and programming, and details about what is in each kit:

To order one
Send me the appropriate amount on PayPal and a note with how many you want. If you don't Paypal, PM me and we'll work something out.
I will be at open house tomorrow (April 18) to distribute them, and can also leave them in the Drop Box if you like.
At the next SMD workshop, I'll try to be on hand to help build them and program them and answer any questions.
