Because of the small progress in the project, it's time to give some more info.
Two prototypes of the sensor reached me. First problem was to change the frequency it works on (from 1MHz to 12MHz, for the v-usb software to work).

Additionally we wanted certain parameters to be displayed on LCD

As You can see on the picture, it was successful

Currently Michał is trying to implement USB support in the device. Next step will be communication test and developing BOINC application.

You can't see the SBM-20 tube yet on the picture, because for the tests the tube and the transformer ware disconnected.
