You know me, I like to get my feet involved when I use my computer, which happens pretty much all day every day at this point. My cache of pedal inputs keeps growing like mushrooms in the darkness under my desk: every upper case letter in this post and dozens more have been capitalized with a shift pedal!
Naturally, I’ve thought about what it might be like to mouse with my toes. The more time I can spend with both hands on the keyboard, the better. I started sniffing around for foot-sized trackball candidates, thinking maybe I could just build one with regular mouse guts. Then I found a 15-year-old Golden Tee home edition console at a thrift store. It has a large ball and four buttons, so it seemed ripe for turning into a mouse as-is, or just stealing the ball to build my own. So far, that hasn’t happened, though I did solder a bunch of wires for testing out the controls. Continue reading “Inputs Of Interest: BIGtrack Mouse Might Make You Squeal”→
Some of us are suckers for new hardware. There’s absolutely nothing shameful about a drawer overflowing with gamepads, roll-up keyboards, and those funny-shaped ergonomic mice. MyTeleTouch won’t sate your itch for new hardware because [Dimitar Danailov] didn’t design hardware you hold, because it uses your phone as a catch-all Human Interface Device, HID. A dongle plugs into a standard USB port, and your Android phone can emulate a USB keyboard, mouse, or gamepad over Bluetooth.
Chances are high that you already set up your primary computer with your favorite hardware, but we think we’ve found a practical slant for a minimalist accessory. Remember the last time you booted an obsolete Windows desktop and dug out an old mouse with a questionable USB plug? How long have you poked around the bottom of a moving box trying to find a proprietary wireless keyboard dongle, when you just wanted to type a password on your smart TV? What about RetroPi and a game controller? MyTeleTouch isn’t going to transform your daily experience, but it’ll be there when you don’t want to carry a full-size keyboard down three flights of stairs to press {ENTER} on a machine that spontaneously forgot it has a touch screen. If you don’t have opportunities to play the hero very often, you can choose to play the villain. Hide this in a coworker’s USB port, and while they think you’re sending a text message, you could be fiddling with their cursor.
We enjoy a good prank that everyone can laugh off, and we love little keyboards and this one raises the (space) bar.
The feedback effect is run by an Arduino, which receives serial data from a Python program running on the host computer. When the mouse is clicked, the Python program notifies the Arduino, which then fires a bank of four solenoids repeatedly back-and-forth to generate the feedback effect. The solenoids are triggered by a relay, which is an easy way to switch such a load, though we suspect it may not hold up well over time due to the rapid fire rate and the likelihood of spark damage over time from high inrush current to the solenoids.
It’s a simple build that nonetheless adds a great haptic feedback effect to the otherwise humble computer mouse. While we don’t expect to see pros using the device anytime soon, it’s a great concept that does add to the shooter experience. Similar hardware could likely be put to great use in a VR context, too. The state of the art of haptic technology continues to move at a rapid pace, and we can’t wait to see what comes next. Video after the break.
Cats are nature’s born hunters. Whether its rodents, insects, or lasers, they’ll pounce and attack with ruthless efficiency. Built to challenge a cat, or perhaps merely to tease it, Sourino is a robotic mouse built with common off-the-shelf parts.
A test subject appears unamused.
So named for the combination of Souris (French for “mouse”) and Arduino, the project is driven by an Arduino Nano. Hooked up to three sets of ultrasonic transducers, this gives the robot mouse much improved obstacle avoidance abilities compared to using just a single transducer front-and-centre. The ‘bot can navigate basic mazes or household floors with ease. A pair of geared motors are used for drive, using simple skid-steering to turn corners. It’s all packed in a 3D printed enclosure, which mounts the various components and exposes the ultrasonic sensors. There’s even an IR remote enabling mode selection or full manual control.
While the ‘bot lacks the speed and agility of common house mice, it’s nevertheless a project that teaches plenty of valuable lessons. We’re sure [Electrocat01] picked up plenty of skills in robotic navigation, mechanical design and 3D printing along the way. Creating robot mice is actually a competitive field, as we’ve seen before. Video after the break.
At a time when practical graphical user interfaces were only just becoming a reality on desktop computers, Apple took a leap of faith and released one of the first commercially available mice back in 1983. It was criticized as being little more than a toy back then, but we all know how that particular story ends.
While the Apple G5431 isn’t that first mouse, it’s not too far removed. So much so that [Stephen Arsenault] believed it was worthy of historic preservation. Whether you want to print out a new case to replace a damaged original or try your hand at updating the classic design with modern electronics, his CAD model of this early computer peripheral is available under the Creative Commons license for anyone who wants it.
The model is exceptionally well detailed.
[Stephen] tells us that he was inspired to take on this project after he saw new manufactured cases for the G5431 popping up online, including a variant made out of translucent plastic. Realizing that a product from 1986 is old enough that Apple (probably) isn’t worried about people cloning it, he set out to produce this definitive digital version of the original case components for community use.
William English, one of the creators of the mouse back in the 60s, passed away last week. And that got me thinking of how amazing it would have been to be in the place that was inventing what would become modern computing interfaces. What a special time! Of course, they probably had no idea.
From here, it looks like the mouse changed everything, but you have to realize that they were working in a world with light-pens, where you could actually draw on the screen. In contrast, the mouse seems positively non-futuristic. They must have known they’d come up with an improvement over the status quo, but did they know they’d created a revolution?
So where has the revolutionary spirit in DIY human interface devices gone? I’d claim it’s still alive and kicking. Indeed our own Kristina Panos has a series called “Inputs of Interest” and we’ve seen a ton of DIY keyboards of late. Then there are many varieties of dial inputs. I used to have a dedicated scroll wheel made out of a hard-drive platter, and when I was reading lots of PDFs on-screen, I have to say it earned its desk-space. Heck, we’ve even seen people make their own mouse.
But what I love about the story of the development of the mouse is that they asked the question “what is the best way to locate a point on a screen” and tried to answer it. Half of their success is probably in simply asking the right question, and the other half in prototyping something half-workable. My gut says that we don’t have inputs figured out 100% on mobile yet. This sounds like a job for Hackaday. What’s the next big human-interface design need? And have you got any crazy ideas to solve it?
Hackaday Remoticon
And this week, we announced the Hackaday Remoticon, our shelter-in-place version of the Supercon. It’s going to take place in November as usual, but online instead of IRL.
The good news? It’s going to be chock full of workshops, all streamed online and recorded for posterity. And for that we need your proposals. If you’d like to teach a group of distributed hackers learning your favorite techniques and tricks, this is your chance!
The bad news is of course that we won’t get to see you all in person. That’s going to make the 2021 Hackaday Supercon seem even more super.
This article is part of the Hackaday.com newsletter, delivered every seven days for each of the last 200+ weeks. It also includes our favorite articles from the last seven days that you can see on the web version of the newsletter.

Every piece of technology starts with a vision, a vague notion of how a thing could or should be. The computer mouse is no different. In fact, the mouse was built to be an integral part of the future of personal computing — a shift away from punch cards and mystery toward a more accessible and user-friendly system of windowed data display, hyperlinks, videoconferencing, and more. And all of it would be commanded by a dot on the screen moving in sync with the operator’s intent, using a piece of hardware controlled by the hand.
The stuff of science fiction becomes fact anytime someone has the means to make it so. Often times the means includes another human being, a intellectual complement who can conjure the same rough vision and fill in the gaps. For Douglas Engelbart’s vision of the now-ubiquitous computer mouse, that person was William English.
William English was born January 27, 1929 in Lexington, Kentucky. His father was an electrical engineer and William followed this same path after graduating from a ranch-focused boarding school in Arizona. After a stint in the Navy, he took a position at Stanford Research Institute in California, where he met Douglas Engelbart.

Engelbart showed William his notes and drawings, and he built the input device that Englebart envisioned — one that could select characters and words on the screen and revolutionize text editing. The X/Y Position Indicator, soon and ever after called the mouse: a sort of rough-yet-sleek pinewood derby car of an input device headed into the future of personal computing.
William’s mouse was utilitarian: a wooden block with two perpendicular wheels on the bottom, and a pair of potentiometers inside to interpret the wheels’ X and Y positions. The analog inputs are converted to digital and represented on the screen. The first mouse had a single button, and the cord was designed to run out the bottom, not the top.
Naturally, I’ve thought about what it might be like to mouse with my toes. The more time I can spend with both hands on the keyboard, the better. I started sniffing around for foot-sized trackball candidates, thinking maybe I could just build one with regular mouse guts. Then I found a 15-year-old Golden Tee home edition console at a thrift store.
