avalanche VS ErgoWarp

I have been unable to get the Avalanche v4 keyboard I just built to communicate over a TRRS cable using I2C or serial. I'm trying to get serial working right now to keep things simple, but I'd eventually like to get I2C working instead. Right now, whatever side is connected to the computer works but the other side doesn't send any input despite the pro micro's LED turning on to show it's getting power.

I've been researching these keyboards for a while now and want to start with the Avalanche https://github.com/vlkv/avalanche . I was thinking it would be cheapest to have the top plate be a PCB, I know I can upload the Gerber files to get them printed, but I'm not sure if that's all there is. My question is, if I upload the top plate gerber files do I have to request anything from the manufactures to make sure the keys will fit? Also, can you recommend some online PCB and 3D printers that you believe are trustworthy vendors. Any tips/resources for a first time builder is also appreciated.

Avalanche – ALL the thumb keys

Interesting! I'm currently in some kinda wierd limbo where I'm hovering between the Iris, the Avalanche and/or waiting on the Elora, aka Kyria with number row, which should be available Soon™. How would you compare the Iris and the Kyria? The aggressive pinky stagger has me a bit leery, but at least printing out the layouts it feels kinda comfy.

Try Avalanche https://github.com/vlkv/avalanche It checks all your boxes.

I didn't design the PCB, just the 3dp case that is in this post. This is the creator: https://github.com/vlkv/avalanche. I think it's for Cyrillic languages that need some accent keys. For me, an English user, i just put ESC or a mod over there when I use my Avalanche.

Avalanche – 7 thumb keys, break-off top row, break-off pinky key

A Dactyl handles some of the press angle, and splay is the term to describe pinky (and other fingers) outward motion angles on the horizontal plane. I have yet to see a keyboard implement both besides the really interesting ErgoWarp. https://github.com/pseudoku/ErgoWarp/blob/master/Photo/Proto6.jpg

The ErgoWarp has an arch in the x-direction.

I am intrigued by the thoughtfulness behind https://github.com/pseudoku/ErgoWarp. Like, enough that I'm tempted to build one. But it looks like a PITA to build, and even more so to get used to, and project looks dead... Has anyone tried one and would you share your experience?

The ErgoWarp has finger joint lengths as parameters. But it seems to me to be numerically fragile, and even after being based on hand measurements and some kind of fancy interpolation, it still has a section for tweaks. That means the fancy math isn't quite good enough to directly generate a perfect keyboard!

The ErgoWarp has a slight negative horizontal curvature. It's also the only one I've seen where you shave down your keyswitches and keycaps so you can fit more. I want to explore that.

This diagram would place the ErgoWrap on the seabed.

https://github.com/pseudoku/ErgoWarp probably, but this project looks to be dead.
