I got busy with other stuff for the last 6 months or so and did not have much time to work on this project. Things will settle down in the summer and I plan to get back to work on the ESP32 version. I've been doing a lot of design work in the background and have a few I I want to try out. ESP32s are very capable uC's and there was (and still is) a lot for me to learn to make effective use of their capabilities.

In the meantime, I've sent the VMFB I was using to Crowbuddy. He is also in NL, has already designed a machine of his own, and plans on working with a local high school on a related project. Crowbuddy has a very robust, installation-type device that is solar powered and has been deployed in several public areas in Europe. I hope we can collaborate later this year.

So it's not over yet :)
