When I found this sight, I was uncertain if one could still buy this device or if the owner was even still active, but then I checked the front page: "March, 2020: Orders may be delayed due to the COVID-19 situation. Thank you for your patience and understanding." The previous news post was from 2017. I think the owner's commitment to this project is amazing. I think that that the owner had to explicitly call out delays due to COVID-19 is also noteworthy.
