Ploopy Bean: The Open-Source Pointing Stick Mouse That Breaks the Mold
Introduction: Rethinking Computer Input
The computer mouse market is saturated with countless designs, from ergonomic vertical mice to gaming-centric models with RGB lighting. Yet, for those seeking something truly different—like a trackball, trackpad, or a pointing stick—the options narrow considerably. Enter the Ploopy Bean, a quirky yet functional input device from a Canadian company known for its playful name and commitment to open-source hardware. This compact pointing stick mouse combines the precision of a TrackPoint-style controller with four customizable buttons and the power of QMK firmware, offering a unique blend of nostalgia and modern customization.
What Is the Ploopy Bean?
The Ploopy Bean is a pointing stick mouse—essentially a desktop version of the joystick-like nub found on many laptops (like Lenovo’s TrackPoint). Instead of moving the entire device, you push the stick to control the cursor. It features four physical buttons: left, right, middle, and a fourth button (often mapped to scroll lock or a custom action). The entire device is built around the open-source QMK firmware, meaning users can reprogram every key and behavior to suit their workflow.
Key Specifications
- Input type: Pointing stick (analog joystick)
- Buttons: 4 tactile switches
- Firmware: QMK (fully open-source, customizable)
- Connectivity: Wired USB (USB-C)
- Compatibility: Windows, macOS, Linux (via standard HID)
- Design: 3D-printed case, hand-assembled in Canada
Why a Pointing Stick Mouse?
Most users are familiar with traditional mice or trackpads, but pointing sticks offer distinct advantages:
- Minimal hand movement: Keep your hands stationary—great for productivity and reducing strain.
- Precision: Fine control without accidental clicks (common with touchpads).
- Space-efficient: No need to sweep the mouse across a desk.
However, standalone pointing sticks are rare. The Ploopy Bean fills this niche, especially for enthusiasts who miss the TrackPoint experience on desktop or want a dedicated device for keyboard-centric workflows.
Open Source and Customization
Perhaps the most compelling aspect of the Ploopy Bean is its firmware. QMK (Quantum Mechanical Keyboard) firmware, typically used for mechanical keyboards, is fully open-source and enables deep customization. Users can remap every button, adjust pointer sensitivity, and even create macros or layers. The hardware schematics and 3D-printable case files are also publicly available, encouraging tinkering and modification.
QMK Features on the Ploopy Bean
- Key mapping: Assign any keyboard shortcut or mouse action to each button.
- Pointer acceleration curves: Fine-tune how fast the cursor moves relative to stick pressure.
- Layer switching: Create multiple layers for different apps (e.g., a gaming layer with different sensitivity).
- Macros: Record and assign sequences of keystrokes or actions to a single button press.
This level of control is rarely available in off-the-shelf mice and makes the Ploopy Bean a dream for power users, programmers, and accessibility advocates.
Build Quality and Design
The Ploopy Bean is hand-assembled in Ontario, Canada, using a 3D-printed case. While the aesthetic is utilitarian (think exposed screws and a slightly rough finish), the internals use high-quality components: ALPS switches for the buttons and a genuine ALPS pointing stick module. The device feels solid and the stick returns to center reliably. The USB-C port is recessed to protect the cable.
Some users note that the pointing stick requires a brief learning curve—especially if you’re used to a mouse—but after a day or two, it becomes intuitive. The four buttons are positioned for easy thumb access, and the overall footprint is smaller than a typical mouse, making it ideal for travel.
Who Should Buy the Ploopy Bean?
- Keyboard enthusiasts who want to keep their hands on the home row.
- Programmers and editors who need precise cursor control without moving their wrists.
- DIY and open-source fans who love to mod and customize their gear.
- Anyone with repetitive strain injuries looking for an alternative to a standard mouse.
It may not replace a traditional mouse for everyone (especially gamers who need fast, broad sweeps), but as a secondary input device, the Ploopy Bean shines.
Comparison with Other Alternative Input Devices
| Device | Type | Buttons | Customization |
|---|---|---|---|
| Ploopy Bean | Pointing stick | 4 | Fully QMK |
| Trackball mice | Ball | 5+ | Often limited |
| ThinkPad TrackPoint | Pointing stick (laptop) | 3 | Software only |
| Touchpads | Capacitive | Gesture-based | Driver dependent |
Unlike most alternatives, the Ploopy Bean’s firmware is fully open-source, giving users control that even premium trackballs rarely offer.
Where to Buy and Community
The Ploopy Bean is available directly from the manufacturer’s website (ploopy.co). As an open-source project, you can also download the design files and build your own if you have access to a 3D printer and soldering equipment. The community around Ploopy is active on forums like Reddit and Discord, sharing custom keymaps and mods.
Price: As of this writing, the Ploopy Bean costs around $50–$60 USD (shipped from Canada), making it competitive with entry-level ergonomic mice but with far more customization potential.
Conclusion: A Niche but Powerful Tool
The Ploopy Bean isn’t for everyone—it requires adjusting your workflow and embracing a slightly unpolished physical design. But for those who value open-source freedom, precise point-stick control, and the ability to remap every aspect of their input device, it’s a game-changer. In a world of generic black mice, the Ploopy Bean stands out as a testament to what a small team can achieve with passion and transparency.
