Has anyone here tried building a "Floaty" digital hydrometer? I have searched and haven't found anything. It seemed simpler than the iSpindel, but when it didn't work I've had trouble finding help. It is based in Spain and although they do reply to help requests, the time difference makes this very slow and I haven't been able to get anywhere.
