Is this basically just the inverse of an electrostatic speaker? I've seen DIY builds of those using very thin films coated with some electrosensitive solution - would that work as an alternative for the foil/leaf used here?

No, a ribbon microphone is sort-of a dual of a dynamic microphone if you squint hard enough. An electrostatic speaker is closer to the inverse of a condenser (capacitor) microphone

Ribbon mics: Expensive, and notoriously fragile (to high SPL). Some are so sensitive that you can actually destroy the ribbon by shutting the (mic) case lid too fast.

As you’ve pointed out High SPL isn’t what breaks ribbons, it’s high SPL at low frequencies (ie wind/air moving frequencies, like those produced from a slamming wooden case lid.

Kick drums and bass guitar amps might not be a good match for a ribbon, but speech (with a pop filter) is fine.

Modern mics like those from Royer Labs can handle high SPL (cranked 100w guitar amp).

There are a few reasons why professionals still like ribbons for certain tasks: unlike condensers and dynamics, the resonant frequency of the ribbon is typically very low (20Hz), so you don’t get any peaks or artifacts when the source audio vibrates at the resonant frequency of the mic. Also, if you like the sound of your expensive mic preamplifier, the low output ribbon mics let you add gain/dirt/harmonic distortion which to some is pleasing to the ear.

Love that the op built his own, that’s really awesome.

Yeah, I have a Royer R-121 which I use in combination a SM57 on guitar cabs/amps - classic combo as you get the fullness and low-end of the Royer, and attack and top-end of the dynamic. But eyewatering price when considering it's only one microphone (though it has more use cases, like overhead).

With that said, every ribbon mic I've owned, I've felt like I've had to handle with kid gloves, just in case.

I built a ribbon mic from a kit a while ago, and only broke the ribbon once putting it together! https://www.bumblebeepro.com/ Of course, as soon as i tried to record my guitarist with it, he cranked his amp and broke it again. Guitarists, man...

Recording drum kits with them must be a delicate business…

Is the frequency response purely a function of the physical shape? I wonder why you can't use a similar diaphragm shape but as a condenser?
