I bought a Geiger counter last week. For the first trial, it worked well because the terminal program showed ‘0’ or ‘1’. However, when I tried it after a few hours, it didn’t work and serial communication port was disappeared from the host computer, and moreover I found that one IC (FTDI***) which is located next to mini USB connector is VERY HOT. I got burnt on the finger. Because green LED flashes once a few second, some parts may be still alive. I think that USB-serial converter and/or some other parts are broken and must be repaired.
I was wondering if someone could suggest what I have to do at this time.
