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.
'standard tools create wonderful things' ❤️.
Please ignore the super shiny reflections...
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.
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:
I am grateful for such a well-documented and open project. Truly, by hackers for hackers!
In the same spirit as an earlier post, here is a quick hack I used to get my dual-headed Prusa XL printer to print with three materials at once.
While the technique worked, it may not be the best method, so proceed with caution.
I am trying to print a part that requires two different materials at the same time: ABS and TPU.
The shaded blue area is meant to be TPU/FLEX material. The shaded yellow area is meant to be ABS material.
I guess this is becoming a tradition now?
During China’s Single’s Day sale on AliExpress, I bought various gadgets - both for projects and out of curiosity. Rather than write separate posts, here’s a collection of mini teardowns showing what’s inside each item.
Previous years:
I’m always looking for a better scene controller/switch/Home Assistant interface. I was curious about which chip they used for the full graphics display and was hoping for an easily hackable Android device. Unfortunately, no such luck with this.
