That would simplify things. How do nodes usually identify themselves to be able to join the network? Maybe a QR code?

I think most ZigBee and Thread chips use 2.4 GHz which limits distance. A lot of water meters are underground on the front yard somewhere so sub gigahertz radio would penetrate bet…

So if I understand correctly, they used hard coded constants to generate keys that only have 44 bits of entropy, which is brute forcible for $10, but you have to do it per device. …

I built (and currently testing) a 4 port automated PCB test & programming tool. I needed a way to produce a bunch of PCBs efficiently and couldn't find a solution that was flexible…

Very cool project. Congrats. I will be trying this out. Two other project I saw that are somewhat related for those interested: 1. reddit community (r/xteinkereader) building an OS…

For those that want more details on how the software works, this guy goes into a bit more detail for his version Fluid simulation pendant https://mitxela.com/projects/fluid-pendant…

If you just want a simple UI editor and don't want to pay for the official tool, give GUI Glider from NXP a try. https://www.nxp.com/design/design-center/software/developmen...

Super impressive project, especially for what seems to be your first embedded project. I haven't played with microPython/uOTA so this was an interesting read. Since you mentioned t…

I started working on my opensource water meter again ( https://y-drip.com/ ). Hardware is basically done so I'm working on the backend website for those that don't want to setup th…

Hey HN, I recently launch a side project selling software on Shopify and needed a way to for users to manage their software license. Shopify's sample Django app was out dated and d…

Thanks, good to know. I may need to request a 3A 1U in that case. I didn't know iDRAC could measure real time power usage. Pretty amazing.

This is a pretty cool solution. I didn't know the capabilities of USB4 before this. The comparison with the Dell r630 power numbers got me interested since I just purchased a Dell …

Thanks. Detecting slow leaks while also conserving battery life is tricky so I opted to do it in hardware with digital logic. I keep a count of all of the low speed revolutions of …

Hi HN, I'm developing an open-source water meter for Home Assistant and thought the HN community might be interested. I've been using some version of it after a few costly toilet l…

Someone mentioned https://inventree.org which looks cool, but there is no distributor API connections AFAIK. I really wanted to ability to scan my Digikey bags and have it auto fil…

Strange. That's one of the reasons my leak threshold is customizable. My city water meter has an LED that turns on when it detects a leak, but I've never seen it work.

Interesting. Do you mean the leak is intermittent and Flume isn't able to detect it? I would love to know more.

I'm building an open source water meter to detect costly water leaks and track your water usage. The hardware design is flexible enough to easily repurpose it for measuring residen…

I used a similar screen to display the user interface for my DIY reflow oven. The raspberry Pi and Linux is overkill for this project, but it's so much easier building a GUI than o…

Something interesting I learned during one of his seminars was that breathing exercises can go a long way in providing most of the benefits. A lot of the media coverage focuses on …

If you are into lifting, anything from All Things Gym or Hook Grip. They focus on weightlifting, but it's fun to watch top athletes do their thing. You can also learn from their wa…

My theory is Android is too difficult to maintain. There is a significant amount of work that has to be done to keep up with the latest version of Android especially if you are goi…
