Looks cool, it's great to have another good open source ready-to-fly option.

Nice size. I have some concerns about larger quadcopter designs because I can imagine the harm of heavy weight drones.

I once needed a locksmith to come let me in my front entryway. Incredibly, he approached with an long plastic sheet and wedged it between the strike and the edge, quickly opening the entryway. I wasn't even mad about it cost $75, I learned in a cool new stunt that day and furthermore figured out how uncertain some doors are.

I have a similar device the KM9P with S912. Linux runs successfully but no wifi. I tried the recent ones but no wifi devices are being detected. So stick to devices with know compatibly like the one from the article.

Wow, so ESP32 as ten times more ROM/Flash and RAM memory than previous ESP8266 chip.

QUALITY tutorial... I just did one and am not sure I explained as concisely

More than 4 people in a hunting party will scare any game. Small groups have evolution advantage.

Nice. With this method you don't need the Xiaomi hub, just this Zigbee USB stick. You can control other kind of Zigbee devices, such as Philips Hue or Ikea bulbs with this as well and you don't need to worry about any data secretly being sent back to Xiaomi in China.
