Awesome video. Now we are talking! I may not have all the parts to build the lego model per-se, but I could probably 3d print the frame anyway. I am more interested in the 'hard to get parts' which you hint might be possible to ship and seeing if the arduino (or esp8266, or upcoming esp32?) can do the job of the electronics.

I have been previously critical about trust and this kind of openness is a big way to build trust back. Thank you.
