Maybe for some context - although Jeff Geerling does provide it too in his video - most 'server' motherboards have build-in KVM. I will make the bet that build-in KVM is more responsive and those interfaces are now HTML5 based, so no nasty Java applet stuff. Motherboards / servers with KVM will consume around 8-10 watt extra, even when powered off, as the KVM solution is basically a tiny computer running Linux + prop…

For some more context why such a device is desirable: Mainboard-built-in KVMs provided by server vendors are usually buggy as hell closed-source horrors, with regular full-compromise holes that make running them over the Internet a complete gamble. This is why open-source KVMs that are just as secure as other normal Linux servers, and auto-upgradable, are very desirable.

I think the main use case are home and maybe small-business servers which generally aren't built with actual server hardware. Just look at the rack in his video which was basically just a bunch of desktop PCs on their side.

In all this, I've not seen any mention of what "KVM" means...

Good to note—I should at least in the video have a little text overlay that shows 'KVM = Keyboard Video Mouse'. You forget sometimes how acronym-laden our industry is, and even the ones you find most basic... better to spell it out for someone who might not operate in the same area.

It's more important that one learns what a KVM is rather than what the letters stand for. Like you don't need to know what laser stands for to know what a laser is.

Edit: I say these here mainly because expanded out, the title says "Raspberry Pi 'Keyboard Video Mouse's Compared". That still means nothing to someone who doesn't know what a KVM is (actually makes it sound like HID devices specifically made for the Pi).

PiKVM v3 HAT on Kickstarter right now. https://www.kickstarter.com/projects/mdevaev/pikvm-v3-hat // I'm the author ;)

Are there schematics / gerber files / project files available for the Pi-KVM v3 HAT? I would be excited to support an open-hardware project.

It's open source, but not open hardware. All the code is completely free, so closed hardware is our way of monetization to continue development.

I want one of these with an LTE modem on it so that I can drop it in the rack (non-datacenter) and remote-in regardless of the WAN condition.

Almost weird that there isn’t endless numbers of such devices from AliExpress. Something like Wio LTE with some pieces of code from GitHub.

Would be awesome after you make some money back if you could open hardware it for those of us who require full trust!

Jeff Geerling just writes "including BIOS/UEFI". In my extremely limited experience without deep insight it works with some computers while on others the BIOS screens remain black (while the Linux console works correctly). We got it for BIOS work, but that plan did not really work out.

My experience with HP iLO with the html5 upgrade is extremely positive, to be frank. Nothing buggy at all.

Even more when the same acronym is also used for Kernel based Virtual Machine.. very confusing!

Thanks for sending me the prototype to test; besides the labeling issue, and the fact that I accidentally fried one of the fan power cables (thought I'd burnt up the whole unit!) when I first put it together, it's already a great product. I hope you sell many more thousands, and keep improving the experience!

Same here, I hope you sell a LOT of these, because it's still a bit expensive for my home lab stuff and I want you to benefit from economies of scale so I can buy a hat for around sixty dollars.

you can buy USB hdmi capture dongle for $10, its 1080@30 mjpeg, but nothing beats that price
