m15 Remake
ed_:
I would like to make my own m15 by cutting a model m, remove the numpad and make an adjustable, ergonomic case.
I assume that I can re-solder the cut traces, but I don't know about the membrane. Also, I may want to replace the controller with one that can support dip switches, but I have not found any.
Any tips would be appreciated. Thanks.

You could use a programmable controller but you wouldn't have dip switches. If those are a must using an AVR would be an option.

You are not going to cut a pcb?
You'll probably need two Ms. At least two membranes.

Thanks for the links; I wasn't finding any good info on keyboard controllers, and was almost ready to program my own, but that's way below my ideal level of abstraction.

I was planning on cutting the PCB, and then fixing the severed traces with wires; I just don't know how to accomplish the same with the membranes.
Thanks.

There is either a membrane or a switch pcb, not both. You might have to do some research on M internals?

The boards are still on the way, so I haven't personally looked inside yet, but all I have read suggests that they each have a PCB and two membranes.
