Green Eggs

Someone doesn't like green switches

Something to appease your coworkers who hate clicky switches.

This was originally supposed to look like a doughnut. But it makes a better egg, a green egg.

8 switches connected to a Pro Micro.

Runs a simple Arduino sketch. Gerber files on git.

Monster POS

5x5x9 Macropad with POS keycaps

225 key macropad covered with POS keycaps. Most are DSA some are DCS. 2x1, 2x2 and 3x1 keycaps.

 Mostly DSA profile. The "Yes" keycap is DCS.

All POS keycaps.

Showing the base of the keyboard and the PCB and plate layers. The Maple Mini sticks out the top.

Half n Half

Another split keyboard

I made this a while ago. It's sort of a wider Gherkin with dedicated thumb switches.

Construction is the same as a 25 or foobar. It is a single PCB design that can be assembled flipped, either left hand or right hand side up.

Gerber files on git. Firmware on git.

Blank XDA keycaps. XDA has many smaller space bars. Since the space bar is isolated you can use whatever size you want.

Both halves connected with a TRRS cable.

A second PCB is used as a base. 3M rubber bumpons.

M2 spacers and screws. Pro Micros and TRRS jacks.

Too many pens

EasyEDA/JLCPCB have been sending a pen with each order. The collapsible "Pill" pen is from Flashquark.

JLCPCB stopped including a pen in the last few orders I've received. They must have run out.

Tall and Short

Two 4x4 macropads

A 4x4 with a SA keycaps and a Chocopad from

Fat and thin. The two extremes available in current mechanical switches and keycaps.

Both are powered by a Pro Micro.This is a Rev 1.0 Chocopad. The ones is selling now are black and have a nice bottom PCB.

1.5 inches tall vs 0.875.

Kolea Case

Top and bottom plates for the Kolea

I broke one of the switches on my Kolea when I dropped it. The switches are very exposed. I made these plates to make the Kolea much sturdier. It will also make it possible to use plate mount switches as well as PCB mount ones.

Gerber files on git.

The switches are held much more securely with the top plate.

I scuffed up the PCB to take off the shine. There is a hole in the bottom plate to access the reset button the Teensy LC.

The plates are held together with M2 spacers and screws.
