    This would not be the first such DIY microphone project I've seen over the years. It's really pretty remarkable how many lovely microphones one can actually make out of common and readily available parts and supplies.

    In an unrelated happenstance of troubleshooting maintenance, I actually stumbled across the exact replacement FET, N channel 2 N 3819 transistor at Radio Shaft for a little over one dollar. And it's the exact same transistor one finds in the $3300 plus, Neumann U87's. Of course without a precision test jig and the other necessary test equipment, your average transistor might be a DB or two higher in noise? Nothing you'll ever notice LOL. Even gold colored mylar film, gift wrapping, can be employed and used for diaphragms for condenser microphones. Though it might not feature the same kind of smooth sound one gets from a couple molecules thick of actual spluttered 24 karat gold. And if one is talented and enterprising enough, one does not even need to create a condenser microphone with a transformer coupled output. It can be an active balanced output.

    Ribbon microphones or something else one can design and build at home with common materials and supplies. And doing any of this, will just make you a better engineer through better understanding and knowledge and workings of these types of designs. Good quality dynamic microphones are even harder to make as DIY projects. How do you think all of those Chinese condenser microphones or me? LOL. Probably with a lot less precision than one would do themselves?

    Microphones are about the only thing I haven't designed and built myself.
