KVMs have been a the bane of my existence over the last 10 years. Almost 99% of the time they come with some ancient Java dependency that breaks on any modern OS and is barely usable. Not to mention the nightmare-ish KVM experience big players like OVH and Hetzner provide. This is a superior solution to all of them.

In the very few games I play 60Hz is way too low so I haven't attempted it at all -- I want the maximum Hz/FPS. As for another switch, I am open to ideas if you have them. In my local market I was only able to find like 2-3 of them [that support DP 1.4] and they are all north of $250 -- which I don't mind but it would be non-pleasant to buy 5+ of them just to experiment. Maybe my requirement for DP 1.4 is silly thoug…
My guess is that switch simply doesn't support 144Hz, so if it works at 60Hz then you have your answer.

Or possibly just wiring up a transistor to the power button pin (not sure if it sources or sinks) between motherboard and the Pi, and just hold it high until it boots.

I'm not really into electronics, but I imagine it wouldn't be that difficult to control the switch of a cheap KVM-switch with the GPIO pins of the RPi. One might even control multiple KVM-switches and daisy-chain them.
Haha, I am kind of the opposite: I work on electronics, and am not much of a sys admin. One of the problems I've run into is that I haven't found a single switch solution with enough connections. I could build a multi-level multiplexer with many switches, but that's too much effort. If TinyPilot can support multiple KVM-over-IP connections, it would be a perfect fit for me.
RPis only have 1 OTG port, though. A device that could get it to handle more machines with that single port would functionally be a KVM-switch. I don't think there's a way around that, at least not one that'd be cheaper or more practical.
This looks awesome. I was looking for a solution like this last year. I budgeted a few hundred bucks but couldn't find anything. Ideally would have a way to handle a few different boxes. I did see something called Intel AMT, part of Intel vPro. https://www.howtogeek.com/56538/how-to-remotely-control-your... Does anyone have experience with this? (I have AMD box so doesn't help me) - actually looks like AMD has simila…
If a machine/server doesn't have built in IPMI, I am using an Adderlink Digital ipeps and control it that way 1). Apart from the built in RealVNC server, it also has HDMI video, USB and virtual media support among other things. I have no relationship with Adderlink, but I am a happy user of this product. Not cheap, but worth the price IMHO. 1) https://www.adder.com/en/kvm-solutions/adderlink-digital-ipe...
You could build ~7 devices for as many machines using the article's method.
Most modern x86 systems support boot input/output via serial, as does grub/grub2, the linux kernel and the userspace. It takes some trial and error to get the serial console set up for all steps in the boot sequence, but once that’s done you’ve got out of band access in a standard terminal with output history, copy, paste, etc.
Pair this with a switched PDU or “smart” outlet and you’ve got a full remote managed server on a shoestring budget. Any adjacent or spare computer with a usb port can host a $5 usb serial adapter and play the role of the console server.
This guy has apparently never heard of lynx browser. He wasted $40 and a lot of time because of that!
Fantastic project. Amazing how you overcame each obstacle, and very well written to boot. Kudos. Quite funny how you brought 1000 ms latency down to 200 ms. I wonder how this compares to iDRAC and that Raritan device.
I've used virtually all of the iDRACs. They're probably in that 200ms area (based on my gut feeling w/ no empirical measurements). They've been fairly responsive in my experience.
Because of COVID my work on the road has come to a screeching halt. I was always using my iPad with an external keyboard for nearly everything and became really accustomed to having iMessage always a key command away. Now I work at home at a desktop with Ubuntu. It's a huge disruption to use iMessage now as I have to switch devices/keyboards. I had the thought of doing almost exactly this with the Ligthning-> HDMI ad…
oh, i wrote software that does this over airplay wifi mirroring and a bluetooth dongle as a mouse. i gave up because I couldn’t convince my phone to take a tablet hid profile for seamless mouse capture. it’s messy but I’ll throw it on github in a bit
