Hi KeyMouse folks,

I am sad to report that my right KM Track isn't working. I've tried switching cables and removing the battery completely (& leaving it on and unplugged in case there's a capacitor in there to drain), and can't get it working again - my computer doesn't recognize it at all when I plug it in.

Something similar happened a few years ago (with the left one, I think) and I ended up having to replace the PCB.

Is there something else I can try? Can I buy the old version PCB? It looks like everything is out of stock on the website. Hopefully this project hasn't turned out to be too much a burden, because it's a product that I love and would happily buy again.

Cheers,

Nate

I replaced a an old board in a Track relatively recently, so they still had some left. I haven't been able to get a response from support in a while, though, and I had to stop using the Track because of the issues I experienced after replacing the board.

One thing I have to do after not using the track for a while, is to connect it to a windows machine, then back at my default Mac computer. Something in which the way Windows and Mac handle USB connection differently seems to solve the problem.
My theory is there's some condensor that drains when the track is not used and then it won't connect to the mac, as it doesn't have power, while on windows, usb gives power immediately and charges the condensor, reviving the PCB.

Maybe try that, if that doesn't help, then I guess it's the pcb? :/

I have the old pcb and so far, after many years I only had to replace one mouse sensor and one click-switch.

Because of the higher power draw, I run the KeyMouse Track pair on a powered USB hub. (They do support wireless on the battery as well, but the lag on wireless is shockingly bad, like 500ms or so. I don't know if that is a Mac thing, or an indicator that something else is wrong.)

I've done the opposite. I use it on my Windows PC all the time, and tried switching to a Mac but haven't had any luck.

I tried a powered USB hub as well, and I'm getting nothing. Has anyone ever tried using a 3rd party usb controller in place of the PCB?

Ok, this was a dumb question because obviously each side is designed with the RF pairing which is unique to KM. What I should ask is, has anyone tried swapping out the guts of both sides with a similar but inferior product (like the Ultimate Hacking Keyboard)?

That is something I had not considered. I was actually starting to plan a new build around parts from wylderbuilds.com ... but in theory, I could just find a small board with QMK/VIA support and retrofit it into my Track pair.

I've dissasembled the keymouse track multiple times, the wiring is remarkably simple. each key has a small board with a diode and pins to which jumper cables are connected. so you should be able to hook another board to it and configure the keys in a standard scan-loop. Any QMK board with enough pins should be able to do it.

I was planning to use 2 arduino micros or leonardos when my track's pcb dies. arduino micro/leanardo has a usb hid controller and it's very simple to code it as a keyboard controller.

Keymouse uses RF pairing but I figure a simple 2-wire connection between (ie. a coiled phone cable) would be enough to communicate between 2 arduinos.

the mouse sensor would probably be more complicated though.

Yeah, this is what I was thinking. I don't have any experience with arduino coding, but wonder if there's something that would be set up so I could just plug the jumper cables in.

If anyone here tries any of these ideas, I hope you'll share what you learn. It has been hard going back to a "normal" keyboard.

I hear that! I've felt like calling in sick all week.
