We have already started running classes via video-conferencing. In the first class, we taught our own students in Hong Kong and the Maryland students in Maryland (remotely) to construct a computer using a Raspberry Pi microcomputer, a small touch screen, a keyboard and a mouse.
Then we showed them the design of the solar panel charging system that we designed last year. In future classes, there will be a lot more to teach and learn.
The fun has just started.
