We bought the Un0rick development board from November 2018. I don't think this is a good invention for the user. I successfully burned the .bin file into the board on Linux in December 2018. This part was also confirmed by Luc. In theory, the board is already emitting ultrasound. We used two methods to try to capture the Waveform 1. Using the Arduino m5stack. m5stack didn’t work and made some strange noise 2. I tried to use Raspberry Pi Zero W to control Un0rick. But there are some unpredictable bugs are about IP connecting. So, I think this product is not stable enough. It still has some bugs. I expect to develop more completely to use easier.
