John, I love your mic. Too bad you're not "Adam" or you could call it your "Invisible Hand Mic."?
Dave, The mic is built around a piece of single sided copper clad pc board cut to fit in the pvc pipe. I scraped away strips to make the traces and soldered in the cap and the element that comes with the kit. I had a larger momentary switch that I liked better than the one from the kit so I used that. I feels good in the hand but I haven't had enough feedback on air yet to know how it really sounds. It seems to get the job done though. I haven't put in any kind of screen yet, but I plan to. It's very close to Jack's design but I had originally made it a couple years back for a Hendricks Bitx 20a that's towards the back of the project backlog.?
Keith, you're right, it's 10kHz, and thanks for the keyword, I didn't know it was referred to as galloping.?
Jerry, thanks for the tip!
Vince, I don't remember what it came out of. I wanted the case to be as "up-cycled" as possible so I used a bunch of random circuit boards I had laying around from various parts scavenging forays. It was probably from something non-functional that someone gave me at some point. Maybe a Sony TV? I found some boards that were roughly the right size and shape and depopulated them with a heat gun. Then I cut them down to the right size and used them for the top, front, and rear panels. The other sides are bent sheet metal from a big-box hardware store. I'm pretty pleased with the way the case came out!
