Re: The Jeffree Cell

Today i cut open and tested another 4.33 crystal but the smaller type getting about the same results as the larger one .
But as with both i could not really get it to work with to much liquid ,i had the idea to fill just a small a glass fuse as the holder with one cap removed fill it up and try what i have been doing but sort of in reverse ,i couldn't really see an effect as on top of the crystal in the fuse really so been thinking about it .
I am going to pass on any light experiment as that is pointless until less i know there is waves happening in the liquid that is is the crystal oscillating or stops with to much liquid bit like my first tests .
Perhaps a way to test this is to use the transmitting crystal as is and use another as a receiver in a water bath ...crystals also work the other way where vibration cause electrical voltage out of it i would expect this to be tiny but might be able to pick it up might need a tuned coil and cap ...
Another problem which i was assuming was that crystals were all X cut for oscillating crystals X cut is the type used for a Jeffree cell .....
reading this i could be using something else AT cut ?
