Banana Split Macropad Is Dessert For Your Desk

September 18, 2022 by Kristina Panos 10 Comments

Once again, [Dan Bostian] is ahead of the curve when it comes to bringing bunches of banana puns to the table, but we think you’ll find this banana split macropad quite appealing nonetheless. Does this tasty thing look familiar? It ought to — we discovered, plucked, and uncovered the one-piece version last summer, and this time, [Dan] simply made our two-piece, wireless dreams come true.

Peel back the — oh, forget it. Inside, you’ll find a nice!nano running the show from the right-hand board using ZMK firmware, and a banana-shaped chalk outline on the left-hand silkscreen that represents how completely [Dan] killed it with this build. You can use any switches you want, as long as they’re Cherry MX-compatible in the ~~shoe~~ footprint department.

The PCBs are open source, of course, and so are the printed parts — it’s all there in the repo. As for the stickers, well, you’ll have to produce those yourself.

Pretty Pico Macropad Eases Transition Back To Office

September 3, 2022 by Kristina Panos 33 Comments

[Thomas “Mel” Maillioux] is no stranger to the custom mechanical keyboard game — and faced with having to return to the office, they decided to whip up a sweet little macropad to both commemorate the occasion and make work a bit easier.

This cotton candy-colored block of beauty was designed to pay homage to [Mel]’s favorite joystick, the TRS-80 self-centering number with the single red, square button, and it looks fantastic. They started this journey by studying the key legends on their laptop to determine which macros might serve them best, based on which legends were the most worn.

Fortunately, all the macros they wanted to use — lock the workstation, save the current, active file, minimize/restore all windows, snap windows to the right or left, and volume control — are all macro’d already within Windows, so that made things rather easy.

Hardware-wise, it doesn’t get much easier than a Raspberry Pi Pico, some mechanical switches, an old USB cable, and donor CAT5 pairs so it looks pretty inside and out. Plus, the handy rotary encoder volume knob will mute and un-mute when pressed. We think the snap-fit enclosure looks great, and it needs no supports to boot. If you want to make your own, be sure to check out the repo.

Okay, we lied: macro pad making does get easier, provided you have access to a 3D-printer.

A Customizable Macropad To Make Anyone’s Tail Wag

July 28, 2022 by Kristina Panos 4 Comments

[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.

Odd Inputs And Peculiar Peripherals: Touch This Macro Pad

June 13, 2022 by Jenny List 5 Comments

The need to provide custom controls for complex software packages has been satisfied in many ways, the most usual of which is to have a configurable keypad. It’s a challenge [Meir Michanie] has taken up in a slightly different way, by creating a custom touch-screen macro pad. Unlike the buttons, this allows entirely custom layouts with different shaped keys in any configuration.

At its heart is a versatile ESP32 touch screen development board of the type that can be found easily among the pages of your favorite online electronics mart. The Arduino IDE has been used to program the device, and configuration is as simple of providing it with a PNG of the desired layout, and a CSV file to define the buttons. The whole then connects via BLE where it’s presented to the host computer as a keyboard. The result is one of the coolest macro pads we’ve ever seen, with a limitless number of options.

With such a neat idea it’s perhaps no surprise among the numbers of macro pads that have made it to these pages there might be another take on the same idea.

Odd Inputs And Peculiar Peripherals: A MacroPad With A Handy Layout Screen

June 11, 2022 by Jenny List No comments

The idea of a macro keypad is a great one, a set of keys programmable with frequent but complex tasks. But once programmed, how can the user keep track of which key does what? To save the world from grubby, hand-written sticky labels, here’s [Andreas Känner] with the Badger 2040 keypad — a macro pad with a display to show keymap info that’s fully programmable using CircuitPython.

At its heart is a Pimoroni Badger 2040 e-ink screen and RP2040 board which sits in a 3D-printed enclosure which in turn magnetically attaches to a 3D-printed keyboard enclosure. Inside is an I/O expander board, which is hand-wired to the switches. The firmware allows for easy configuration and even extension of the keypad itself, and presents itself to the host computer through USB. It’s even possible to have multiple different layouts on the same device.

Full details can be found in a comprehensive write-up on his website, and all the files are in a GitHub repository. If this doesn’t satisfy your need for customisable input goodness, then it’s not the first macro keypad we’ve shown you.

Console Macropad Uses SD Cards For Stylin’ And Profilin’

May 26, 2022 by Kristina Panos 7 Comments

Macropads are great to have around for hotkey input, but things can get out of hand pretty quickly when you realize just how many shortcuts are in your life. To avoid ending up with another keyboard-sized keyboard, some hackers will use a handful of switches and a lot of layers to turn a few keys into many. And instead of worrying about legends, they use blank keys and leave the labels to be displayed on some kind of screen.

Among them is [QCJ3], who built this nifty little console-style macropad. Uninterested in managing microcontroller memory, [QCJ3] went the tangible route and loaded various profiles onto a micro SD card. Each text file on a given card holds a label, a color for the keyswitch LED, and of course, the keystrokes that make up the macro itself.

There are myriad ways to build a macro pad, from designing with bare chips (if you can get them) to programming a pre-built key matrix. Grab the files if you like the console look and call it a day, or build a completely new enclosure that fits your hand exactly. Whatever you build, consider entering it in our brand spankin’ new Odd Inputs and Peculiar Peripherals Contest, which runs now through July 4th. If you need more inspiration, just peep the projects under macropad tag, or peruse the much heftier keyboard tag.

CAT Is Not Your Average Meow-cropad

April 9, 2022 by Kristina Panos 3 Comments

Are you completely over the idea of the keyboard in any flattish form and looking for something completely different for inputting your data? Or do you want a mega macropad for 3D design, GIMP or Inkscape work, or to use while relaxing with a nice first-person shooter? Then this ergonomic, double-fistable keyboard/controller mashup named CAT may be what you’re looking for.

Inside each of these slinky felines is pretty much what you’d expect to find — 25 or so switches and an Arduino Pro Micro. Interestingly enough, the switches are all lever-action and not push buttons. There are two breeds of CAT available to build or buy: one has 25 buttons, and the other has a joystick or trackball on the thumb between two upper and two lower buttons. You could have one type for each hand!

More information is available on the Lynx Workshop site, which is where you’ll also find tutorials and instructions for everything from the 3D printing to the electronics to the assembly and coding. There is even a bonus 3D modeling tutorial. Don’t want to invest the time to make your own CAT? These kitties are also available for pre-order. Claw past the break to check them out in action.

Looking for something with regular keyswitches? Oh, we have plenty of those.
