[Gili Yankovitch] has always wanted some kind of macro keypad for all those boss-slaying combos he keeps up the sleeve of his wizard robe while playing WoW. Seventeen years later, he finally threw down the gauntlet and built one. But really, this is an understatement, because Paws is kind of the customizable macropad to end all customizable macropads.

This thing is completely bespoke, and yet cookie cutter at the same time — but we mean that in the best possible way. Paws can be made in any shape or form, and quite easily. How is this even possible, you ask? Well, every single key has its own microcontroller.

Yep, each key has an ATtiny85 and a cute little ribbon cable, and these form a token ring network that talks to an Arduino, which provides the keyboard interface to the computer. To make things even easier, [Gili] built a simple programming UI that automatically recognizes the configuration and number of keys, and lets the user choose the most important bit of all — the color of the LED.

[Gili] wanted to combine all the skills he’s learned since the worst timeline started in early 2020 — embedded software, CAD, electronics, and PCB design. We’d like to add networking to that list, especially since he figured out a nice workaround for the slowness of I²C and the limitations of communication between the ‘tiny85s and the Arduino. Though [Gili] may have started out with a tall order, he definitely filled it. Want to get your paws on the design files? Just claw your way over to GitHub.

Maybe we’re biased, but we think everyone has a use for a macropad. It’s just a matter of time before a highly personalized set of speed controls starts to sound like a great time-saving device to have around.

Trouble is, macropads are usually kind of expensive to buy outright, and not everyone feels comfortable building keyboards. Okay, so what if you didn’t even have to solder anything? That’s the idea behind [Jan Lunge]’s hand-wired macropad.

You will still want to open a window for ventilation if you build this one, because this macropad requires a lot of 3D printing. What it doesn’t require is glue or screws, because everything snaps together.

Of course, the star of this build is [Jan]’s hot swap socket design. We especially love the little clip that holds the column wires in place while also providing a spacer between those and the row wires. Everything is connected up to a Pro Micro with non-insulated wire and held in place with bends at the ends and the magic of tension. Be sure to check out the build video after the break.

Thirsty for more than a six pack of switches? This design is easy to scale up until you run out of microcontroller inputs. At that point, you might want to add screens to keep track of all your macros.

Thanks for the tip, [BaldPower]!
