Why tho? Why not just launch N KVM virtual machines on your linux box? This literally takes minutes, unlike this project which probably took days. And it's much faster once you get it up and running.

Because tinkering is fun and fun is good.

It just seems like there are much more interesting projects available for "tinkering" than building a slow, barely usable Kubernetes cluster.

Like what? Interested to hear what you deem interesting enough to tinker on.

Real question coming from a non-k8-user. What would you use something like this for? Server hosting or?

Ultimately the question is, "how much of the total cpu/memory is used just running kubernetes?" I know prior to rpi4, clusters like this were basically demo/education/bragging rights projects.

It's great for edge computing. Chick-fil-a is using something like this at all their restaurants.

Just about anything not Kubernetes related. I'm currently building a cat toy which combines object detection and reverse kinematics to play with my cat using a laser pointer when she steps into view of the camera.

As a general thought, this kind of power supply seems like what the author was first looking for but couldn't source at the time:

https://www.ebay.com.au/itm/Switching-Power-Supply-DC-5V-12V...

It's a 5V, 20Amp one (thus 100W). There seem to be several of them on Ebay from various vendors.

Using that would mean the 12V laptop power supply, and buck converter to change the 12V to 5V wouldn't be needed. Would probably bring down the cost a little bit too.

Why tho? Why not just use a laser pointer yourself? This literally takes minutes, unlike this project which probably took days. And it's much faster once you get it up and running.

It's just a purely personal preference thing. :)
