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.

Home Assistant Voice: Preview Edition teardown

This is a quick #TwoMinuteTeardown post for the recently released Home Assistant Voice Node - Preview edition.

Normally, I’d be doing a full teardown, but this is a little different; the Home Assistant team has done a lot of the work out in the open. With just a quick Google, you can find official:

• teardown instructions here.
• source code here.
• 3D printable case files.
• Instructions for adding custom devices here.

I am grateful for such a well-documented and open project. Truly, by hackers for hackers!
