Qi wireless power tester

The Qi standard for transmitting power is ~ 15 years old and has been ubiquitous for at least a decade now. And yet, I have only recently seen any testing equipment for it.

The Wozniak WPX-0001A is a simple tester that can measure the output level and protocol of Qi chargers.

Generic liquid level meter teardown

I ordered this part years ago for a project I eventually canceled.

I can’t use it for anything, and it’s just taking up space, so I’m going to open it up before I recycle it.

The Ali Express listing is a 404 so I don’t have a link to share or really any information about it.

The main thing to take away is that it’s meant to interface with a liquid level sensor. It will display the level of liquid in a tank and - optionally - trigger a few relays based on the level.
