Keebin’ With Kristina: The One With The Copycat Keyboard

This is Crater75, an almost completely from-scratch row-staggered wireless split board that [United_Parfait_6383] has been working on for a few months. Everything but the keycaps and switches is DIY.

As cool as a keyboard full of screens might seem, can you imagine what it would be like to type at speed on a sea of slick surfaces? Not very nice, I’m thinking. But having them solely on the Function row seems like the perfect compromise. Here, the Function row keys interact with foreground applications, and change with whatever has focus. For the curious, those are 0.42″ OLEDs from Ali with a resolution of 72×40.

I’m not sure what’s going on internally, but the two sides connect with magnets, and either side’s USB-C can be used to charge the board. Both sides have a 2100 mAh Li-Po battery, and the average current of the OLED displays is low enough that the board can run for months on a single charge.

The switches are Gateron low-profiles and are wearing keycaps recycled from a Keychron, which add to the professional finish. Speaking of, the enclosures were manufactured by JLC3DP using the Nylon Multi-Jet Fusion process, but [United_Parfait_6383] says the left side feels too light, so the next revision will likely be CNC’d aluminium. Be sure to check out this short video of Crater75 in action.

Keebin’ With Kristina: The One With The Breadboard Macropad

For their first custom, hand-wired keyboard, [terryorchard] aka [70rch] didn’t want to mess with making a total split, and we don’t really blame them. However, as you can see, they ended up with a monoblock split, which aside from being our own personal preference, looks fantastic, and also happened to be what fit on the print bed.

What you’re looking at is a 40% remix of the Alice layout with a columnar stagger. It’s also a bit 6×3 Corne-inspired on the ergonomic front. Brain-wise, it’s got an exposed Elite Pi driving a matrix of Kailh Choc pinks and an EC11 encoder. The encoder scrolls by default, and then becomes a volume knob on the numbers and symbols layer. One super cool thing about this keyboard is the secret third layer, which is unlocked by pressing the rotary encoder. This leads to some home row mods and disables the outside columns, culminating in a test 3×5 with two layers.
