This is a very short “announcement” post.
To beef up my home-lab observability stack, I’ve been working on a few projects to expose more data to Prometheus. Getting metrics from my cable modem has been on the “todo” list for literally years. There have been various metric exporters written in the past but they have either been archived/deleted off of GitHub or are otherwise inappropriate for my needs. So, I wrote my own.
This isn’t going to be a long post. I’m working on a larger project but hit a snag and I didn’t find any easy/obvious solutions online so I thought I’d share what I came up with.
Details will come later when the bigger project is ready to be released so you’ll have to forgive me for the lack of context. Essentially I have a large / multi-hour print that almost fits on my MK3s print bed but is too large to slice as is.
It is surprisingly hard to find a device that can dump details about the various protocols and negotiated standards for a HDMI connection. For how ubiquitous HDMI is, you’d think that there would be a lot of devices that can do this. There are LOADS of devices that can snoop USB and Ethernet, but HDMI is a bit of a different beast, apparently.
After a bit of searching, I found the Altinex TE460-137 could do exactly what I wanted.
Single’s Day is a big deal in China and AliExpress has a big sale in celebration.
In addition to project supplies, I found quite a few items that can only be classified as “ohh, that looks interesting and I need another $11 in the cart to unlock free shipping…” items.
I was planing on doing a series of posts covering some of the stuff I bought but nothing on it’s own was really “worth” a full post so instead of a bunch of short “Two Minute Teardown” posts, I decided to just roll everything into this massive post.
To make a long store short, Google recently pushed a few updates to my TV that made it slow as all hell and frustratingly unusable. I finally got fed up with the laggy UI and dug out an old mini PC and installed LibreELEC on it.
Everything worked perfectly except for the lack of CEC support on the mini PC.
This is a common enough problem that there’s a few different devices out there that can add CEC support to a device that doesn’t have it. I chose the Pulse-Eight HDMI CEC Injector because it’s natively supported by LibreELEC.
