-small balloon....air filled. small balloon .... He filled.......did we ever get this to work? It does not with big balloon. Don't recall if tried with small. Idea is to have static hold it to wall or table top, but bump it and it goes up.2017-06-19

-I need a charging and discharging RC circuit on oscilloscope. I can't find that demo by number. Not sure there is one. I think in past we made use of one of your other boards (LCR???) but just charge and discharge........I can use the neon light flashing if the discharge is not so fast as to show instant discharge....i.e. I do see the decay if briefly.2017-07-03
