hollow grinding revisited

[Ken S]

Herman,

I just downloaded VLC for ios (ipad) from the app store, a free app. My USB to lightning adaptor for my ipad should arrive early next week. I will post my results. It would be convenient for me and very convenient for the school if the usb microscope would work with ipads. It can be removed from the stand and used handheld, if desired. The school has a nice greenhouse which is part of the curriculum.
