I have carefully analyzed all of the qualified projects, and I'm ready to announce the winners of the main prize (the OpenMV camera board) and the prizes sponsored by Adafruit Industries (the five Adafruit HUZZAH Feather boards). The prizes sponsored by Espressif Systems (five ESP32 chips) will be announced separately, when I hear from them.

• The first Feather goes to the author of #EncoderLib. It's a simple yet useful device, and there is some new MicroPython code written for it, so that everybody benefit. I wonder if you could make a controller for Arkanoid or Pong with it!
• The second Feather goes to the authors of #Home automation: thermostat with ESP8266 & OpenHab. While at the moment it's just a proof of concept, a lot of work went into researching and implementing this. There has also been quite some testing of the MQTT library.
• The third Feather goes to the author of the #ESP8266 Geiger counter. You never know when you will need one of these!
• The fourth Feather goes to the author of #NASA Wind Decoder. This is a real hacker project, with a lot of details and information, but also entertaining to read. He also uses a fork of MicroPython that has an I2C slave -- perhaps with enough testing this will get eventually merged back into the main branch.
• The fifth Feather goes to the author who submitted three projects, #DHT12 AM2320 Nokia 5110, #Nokia 5110 Conway's Game of Life and #ESP8266 Useless Throwie, covering all bases: a serious project with a library, a "game", and an amusing hack, which seems simple, but which in fact took quite some work and research to make. I wish I had more Feathers to give.
• Finally, the OpenMV goes to the author of #Traffic Signal LED Matrix Display. Not only a great hack, not only very well documented, not only contains a library for reading PNG images, but also has blinking lights! How can a project with blinking lights *not* be the winner?

Congratulations to all the winners (incidentally, everyone who submitted a project that qualified won something, isn't that great), and please contact me here with a private message about how and where I am to send the prize. Big thanks to everyone who participated and of course to the sponsors, without who we would only have a single prize.
