Wanted! A USB-C OTG single button keyboard
I'm writing this post in the hope someone will rip off my idea and start selling it on Ali Express.
Many years ago, I got a "Pressy". It was a little dongle which fitted into your phone's headphone jack. It had a single button on the top. It came with an app so when you tapped the button the app would do something. For example, tap once to open email, double-tap to switch to flight mode, etc.
Most modern phones eschew headphone ports. They let water in, are fragile, and a cheap DAC produces worse sound quality than Bluetooth0.
So would it be possible to have a USB-C component which does something similar?
Technically, yes!
- There are USB-C keyboard which plug directly into phones.
- For a couple of quid, you can get mini keyboards with a custom amount of keys
- I can find a single button PTT USB-C device albeit with a ridiculously long cable.
- The Yubikey 5C nano has the right form factor and comes with a (pre-programmed) single button.
I don't have the skills to solder one of these devices myself. So, who makes one?

Possible alternative - an NFC sticker that activates when pressed, and an accompanying app https://air-button.com/product/air-button-customizable-nfc-button-for-android-phones/
I've not used it, just happened to remember their kickstarter from back in the day.
