# The Noisy Cricket (Mini Gaming Keyboard)
|
|
|
|
A minimal keyboard with just the basic keys for gaming on the go. Mostly targeted at FPS games with a focus on `W` `A` `S` `D`.
|
|
|
|
The layout can be customimzed via the QMK firware. The default layout looks like this:
|
|
|
|
```
|
|
╔═══╤═══╤═══╤═══╤═══╤═══╤═══╗
|
|
║Esc│ 1 │ 2 │ 3 │ 4 │ 5 │Del║
|
|
╟───┴─┬─┴─┬─┴─┬─┴─┬─┴─┬─┴───╢
|
|
║ Tab │ Q │ W │ E │ R │Enter║
|
|
╟─────┴┬──┴┬──┴┬──┴┬──┴┐ ║
|
|
║Shift │ A │ S │ D │ F │ ║
|
|
╟───┬──┴┬──┴┬──┴┬──┴───┴┬───╢
|
|
║Ctl│Fn │ C │ V │ Space │Mut║
|
|
╚═══╧═══╧═══╧═══╧═══════╧═══╝
|
|
```
|
|
The `Mute` key is a rotary encoder that also controlles volume.

When shopping for key caps, you need the following:
|
|
|
|
- 7x R4 1u (`Esc`, `1`, `2`, `3`, `4`, `5`, `Delete`)
|
|
- 1x R3 1.5u (`Tab`)
|
|
- 4x R3 1u (`Q`, `W`, `E`, `R`)
|
|
- 1x ISO Enter
|
|
- 1x R2 1.75u (`Shift`)
|
|
- 4x R2 1u (`A`, `S`, `D`, `F`)
|
|
- 4x R1 1u (`Ctrl`, `Fn`, `C`, `V`)
|
|
- 1x R1 2u (`Space`)
|
|
|
|
Obviously you can ignore the rows when shopping for uniform key caps. 😉

## 2. Solder PCB
|
|
|
|
Solder the Microcontroller first with a heat gun or heat plate. Then solder crystal next to it. You'll need t firmly press the crystal down so it makes a good connection. Then solder everything else by hand.
|
|
|
|
## 3. Software
|
|
|
|
Flash QMK firmware from firmware repo: https://gitlab.com/noisy_cricket/qmk-firmware/
|
|
|
|
```shell
|
|
git clone https://gitlab.com/noisy_cricket/qmk-firmware/
|
|
cd qmk-firmware
|
|
git checkout noisy_cricket
|
|
```
|
|
|
|
Connect the board and execute this:
|
|
|
|
```shell
|
|
make noisy_cricket:default:flash
|
|
# or with the QMK tool: qmk flash -kb noisy_cricket -km default
|
|
```
|
|
|
|
## 4. Case
|
|
|
|
- Get 3D printable case files from https://gitlab.com/noisy_cricket/cad
|
|
- Run `make 3mf` to generate printable files
|
|
- Print `upper_case.3mf`
|
|
- Print `lower_case.3mf`
|
|
- Print `plate.3mf` or run `make dxf` and CNC cut `plate.dxf` out of aluminium or brass
|
|
- Optionally: CNC `weight.dxf` to further increase the weight of the case
|
|
- Optionally: CNC the lower and upper case from wood with the included STEP files
|
|
|
|
