We enjoy access to cheap stuff because of the mass market for things like mice, keyboards, and cell phones. But if you need a device that doesn’t have mass appeal, you will have to pay a lot more if you can find it at all. However, with modern techniques like 3D printing and Arduino-like microcontrollers being cheap and simple to use, you now have the option to build that special one-of-a-kind device. Case in point: [Davy’s] mouse for people who have brain or nervous system disorders. This particular device is helping a 6-year-old who can’t manipulate a normal mouse.

The device uses an Arduino Pro and an MPU-6050 accelerometer and gyroscope. The original design uses machined aluminum, but 3D printing should work, too. There’s something wrong with the link to the design files in the post, but it is easy to find the correct link.

If you do 3D print a similar enclosure, you might consider using heat-set threaded inserts instead of tapping the holes. They work great, are easy to install, and seem to be a bit more robust than trying to thread plastic. Then again, threaded plastic isn’t as bad as you might think.

There are, of course, many ways you could make this work, and besides, every special user will be a little different. But what a great feeling to help someone be able to do what most people take for granted.

If you are lucky, you’ve never experienced the heartbreak of watching a loved one lose their ability to do simple tasks. However, as hackers, we have the ability to customize solutions to make everyday tasks more accessible. That’s what [omerrv] did by creating a very specific function remote control. The idea is to provide an easy-to-use interface for the most common remote functions.

This is one of those projects where the technology puzzle is now pretty easy to solve: IR remotes are well-understood and there are plenty of libraries for recording and playing back signals. The real work is to understand the user’s challenges and come up with a workable compromise between something useful and something too complex for the user to deal with.

Fortunately, with all the prototyping tools readily available now, it is easy to experiment with different setups to see what would work best. Larger keys? Color coding? A different arrangement of buttons? All of those things are easy to experiment with and, of course, what works for one person might not work for another. Even given time, it is possible that different configurations will work better or worse for the same person.

It isn’t likely that you’d duplicate [omerrv’s] remote directly. It may not work for your purpose. But it is a good inspiration on how we can use our ability to create customized hardware to improve the quality of life for those who need help.

We’ve seen similar projects — each one is a bit different. We wonder if old-fashioned remotes with their natural limitations would be a bit easier for people to handle?

For some people, mowing the lawn is a dreaded chore that leads to thoughts of pouring a concrete slab over the yard and painting it green. Others see it as the perfect occasion to spend a sunny afternoon outside. And then there are those without the luxury of having a preference on the subject in the first place. [elliotmade] for example has a friend who’s sitting in a wheelchair, and would normally have to rely on others to maintain his lawn and form an opinion on the enjoyability of the task. So to retain his friend’s independence, he decided to build him a remote-controlled lawn mower.

After putting together an initial proof of concept that’s been successfully in use for a few years now, [elliotmade] saw some room for improvement and thought it was time for an upgrade. Liberating the drive section of an electric wheelchair, he welded a frame around it to house the battery and the mower itself, and added an alternator to charge the battery directly from the mower’s engine. An RC receiver that connects to the motor driver is controlled by an Arduino, as well as a pair of relays to switch both the ignition and an electric starter that eliminates the need for cord pulling. Topping it off with a camera, the garden chores are now comfortably tackled from a distance, without any issues of depth perception.

Remote-controlling a sharp-bladed machine most certainly requires a few additional safety considerations, and it seems that [elliotmade] thought this out pretty well, so failure on any of the involved parts won’t have fatal consequences. However, judging from the demo video embedded after break, the garden in question might not be the best environment to turn this into a GPS-assisted, autonomous mower in the future. But then again, RC vehicles are fun as they are, regardless of their shape or size.
