Keebin’ With Kristina: The One With The Holey And Wholly Expensive Keyboard

An Ultimate Hacking Keyboard (UHK) with DIY rainbow keycaps.

The Ultimate Hacking Keyboard (UHK) line is, as the name suggests, a great choice for a lot of people. They’re each a toe-dip into the ergonomic waters with their split-ability and those beginner thumb clusters.

However, [jwr] was not completely satisfied and decided to make a custom set of keycaps. The idea was to create ‘caps without the “annoyingly abrasive texture of PBT”, that are larger than average for larger-than-average fingers. Finally, [jwr] wanted the Function row to tower over the number row a little, so these have a taller profile.

So, what are they made of? The look kind rubbery, don’t they? They are cast of pigmented polyurethane resin. First, [jwr] designed five molds in Fusion360, one for each row. Then it was time to machine master molds via CNC in foam tooling board. These were filled with silicone along with 3D-printed inserts, which produced silicone molds for casting keycaps four at a time in resin.

Mods Make A Stock Keyboard Your Own

Trust me, you don’t have to build your own keyboard from the deskpad up to be happy or feel like one of the cool kids. Sure, it doesn’t hurt, but not everyone is able to or even wants to start from next to nothing. Take [Roger] for example. [Roger] started with a stock mechanical keeb — the Ultimate Hacking Keyboard (UHK) — which can be outfitted with magnetic add-on modules such as a thumb key cluster, trackball, trackpoint, and touch pad, and made it his own.

While the stock board that you choose may not be so option-laden, there are plenty of other things one can do to customize things, and [Roger] did basically all of them. The Kailh browns that the UHK came with were too loud, so [Roger] swapped them out for Zilent V2 Silent tactiles and dampened the case with plenty of neoprene foam.

[Roger] frequently switches between two keyboard layouts, which got confusing at times. But instead of boring blank keycaps, he scrounged around until he found a cool set. (We do like the way they look with the wood wrist rests.) Speaking of those wrist rests, the right one is carved out and hiding a 10,000 mAh power bank, because [Roger] also made the UHK wireless using one of those often-out-of-stock BT-500 Bluetooth adapters. This allows him to switch between two PCs with a keyboard shortcut.

Think you want to go split, but not sure about key wells and column stagger and all that jazz? Something like the UHK is a good place to start, because it takes the familiar brick wall layout and breaks it into two pieces. No idea what you want? Check out the split keyboard finder.
