lpcats

Low Profile, Curved And Thin, Split keyboard

What is it?

A keyboard based on my other project CKC. This repo will maybe, at some point, contain a build guide.. or at the very least the ckc-config.. which will probably also be an example config in CKC.

Storytime

What i originally wanted was just to have a split keyboard with configurable columns (shape, number of keys, rotations, etc) and thumbcluster, and then for the rest (walls and base) be generated automagically. As i started writing it tho, it turned more and more into a keyboard-generator than just some extra config-options for a predefined keyboard - so, what i first intended to just be lpcats, became CKC. So this repo is likely to be pretty empty until i get CKC to usable state.

BOM

Since i am a AE-shopoholic i have already bought most of the components.

Part	Quantity	Unit Price	Total	Shipping	Store	Notes
Switches	4 x12	$4.00	$16.00	$9.00	Keychron	Gateron LP blues
Caps	1 x117	$14.21	$14.21	$3.14	Aliexpress	XVX Horizon low profile

Lipo batteries, 2Ah	2	$4.20	$8.40	$0	Aliexpress

So just under $60 (excluding consumables and shipping), of course the two most costly items - switches and caps - might run you a lot more a quite a bit less depending on your taste. The shipping, $22 in total, is to sweden and it's worth noting that you can (or well, could, given chip shortages, wars, and so on) get most of the other AE parts cheaper than i did if you can order stuff from china without getting any extra taxes/fees added to them - i pretty much only bought stuff from sellers that could ship from the EU. So all-in-all it's pretty price competitive with even lower end prebuilds, and if you compare it to most sculpted puppers you can throw in an AE 3D-printer and still come out way below average.. given, of course, that you do not value your own time =)
