I know about the very cool HeroComm.com, devoted to the classic TOS communicators. I totally went down the rabbit hole when I first discovered that site. Are there any comparable sites devoted to the TOS phasers and/or even the tricorder props? I'd love to get more nuts-and-bolts info on these iconic pieces. Any pointers would be much appreciated!
Try RAC Props (link). This links to their first phaser related article, but there are other ones in other issues.

I recently checked in on HeroComm.com and was delighted to see they have started separate pages for phasers and tricorders! Lots of great info (though nowhere as comprehensive as their communicator data -- yet, anyway ).
