My rain gauge stopped reporting, so I brought my ISS inside today to try to clean it out. I tried to open it up, but I ran into a problem with the screws. They use cheap Chinese junk for screws, and must have used Bigfoot to tighten them, because I actually ruined one of my screwdrivers trying to get them out. Since these are cheap screws, none of my phillips screwdrivers fit, so I had to use a flat head one. I was able to get 4 of 6 screws out, but the 5th one started stripping, and I wasn't willing to ruin my screwdriver more than it already was. Guess I'll have to hope that running water through the rain gauge was enough to fix it, or I just will have to accept that it won't measure rain anymore.
