• Split keeb with built-in pointer device
  1 project | /r/ErgoMechKeyboards | 20 Oct 2023

  Hi, fairly new to the ergo world. I'm looking for a replacement for my first ergo keyboard that stopped working. It is a 40 keys split keyboard with a 3-keys thumb cluster. I want something with similar keys layout.

• How to wire the two halves of my split keyboard together?
  1 project | /r/ErgoMechKeyboards | 27 May 2023

  I would just solder the wire directly to PCB and hold it in place by tying it with steel wire or even hot glue. Check my prototype here https://github.com/zzeneg/pica40/tree/v1, you can make it prettier if you plan it beforehand, for me it was an accident :)

• Just finished my single MCU corne using wood and marble filament. Love how it turned out!
  1 project | /r/crkbd | 8 Feb 2023

  This build was inspired by the pica40 mostly: https://github.com/zzeneg/pica40

• Any resources/hints on building a semi wireless setup?
  1 project | /r/ErgoMechKeyboards | 28 Jan 2023

  https://github.com/zzeneg/pica40/tree/v1 - my prototype with handwired connection, can easily be upgraded with nice nano and battery.

• PicaChoc36 - low profile split for short pinkies
  4 projects | /r/ErgoMechKeyboards | 11 Jan 2023

  Presenting my first low profile split keyboard. After my experiments with aggressive stagger I thought that it's not enough and I still have to move my hand to reach top pinky keys (Q/P) and it would be more comfortable to have these keys on the side instead. For the sake of the experiment I wanted to try choc V1 switches with choc spacing as well.

• Pica40 v2 - wired/wireless split with XIAO MCUs
  1 project | /r/ErgoMechKeyboards | 8 Nov 2022

  All files are available on my [GitHub](https://github.com/zzeneg/pica40).

• Pica40 - build failed successfully
  1 project | /r/ErgoMechKeyboards | 10 Aug 2022

  In the end I do not recommend building it, but still it's more or less unique design :) My repo - https://github.com/zzeneg/pica40

• Is it possible to create a split with a single controller?
  2 projects | /r/ErgoMechKeyboards | 17 Jul 2022

  If you don't need a lot of keys than you can just extend the matrix to the second half but must use some other cable than trrs. As far as I remember there is a Reviung Split which uses ethernet cable. I've also designed a split which uses usb-c cable for communication, but it's not built yet so proceed with caution - https://github.com/zzeneg/pica40.

• Modifying a PCB to add power switch and JST jack
  2 projects | /r/ErgoMechKeyboards | 19 Jun 2022

  As said, there is no space for the jst connector on corne-like boards. You can place it instead trrs jack but it limits you to wireless communication - can be done though if you plan use it exclusively like this. I'd say it's not needed, you won't change battery often anyway, you can solder the wires and have only a power switch. For example you can take a look on nijuni https://github.com/krikun98/nijuni. If you like nijuni, it would be easier to replace switch footprints to chocs than modifying corne. I can also humble brag about my own design with switch and jst - but note that it's not assembled/tested yet https://github.com/zzeneg/pica40.
