Swedish Senior Rolls In Style With Hybrid Hoverboard Walker

August 19, 2016 by Dan Maloney 25 Comments

You don’t have to know a word Swedish to understand that 86-year old [Lasse Thörn] is the coolaste modernaste pensionären in Gränna. All you have to do is see him rolling on his walker-assisted hoverboard and you’ve got the whole story.

Still, not knowing any Swedish and the spotty nature of Google translations makes it hard to discern the details of this build. Did [Lasse] build the folding aluminum bracket that connects the battery-powered hoverboard to his walker himself? We guess that he did, since another story says that he built a pedal boat back in the 1950s because he thought it sounded cool. He also says that he gets a lot of attention when he’s out on his contraption, and that other seniors have asked him to build one. [Lasse] says he’s too old to start a business; we don’t think he’s giving himself enough credit, but if he’s willing to leave the field of affordable personal mobility open to the rest of us, we say go for it.

We’ve seen lots of hoverboard builds lately, and lots of hate in the comments about the use of that term. Seems like the false advertising vibe grates on folks, but face it: “rolling wheelie board” is kind of awkward, and until technology catches up with the laws of physics, it’s the best we’re going to do.

Hackaday Links: November 1, 2015

It seems almost compulsory that we start off with a dose of Star Wars. Here’s an epic AT-ST build that motorizes the iconic walker.

That two-legger isn’t going to be lonely. It bigger-slower brother, the AT-AT got a bit of motorized love as well.

What? You were expecting a BB8 build? We have one of those too. [DrYerzinia] has begun a design that hides a quadcopter inside of the BB8. The four 17″ DJI propellers fold up when not in use, extending through hatches in the outer shell when it’s time to take flight. This retains the rolling design you’ve already come to love in the BB8 and we’re going to keep our eyes on it!

Do you have a Teensy and some extra WS2812 strips hanging out on your bench? [etix] put his to use with an ambilight clone. This works really well: simple hardware which connects via USB to communicate with VLC. We applaud [etix’s] choice of Kung Fury as a demo video… a truly bizarre and entertaining short movie. +1000 for its use of VHS tape artifacts.

We just missed Halloween, but this set of wings is far too great of a build to be reserved for that one day. Alas, there is only the demo video but seeing the huge feathered structures fold and unfold is really impressive!

[Truebass] added an artistic accent to one of the walls in his home. He had several cellphone chargers from old phones in his junk bin. These were used to regulate power for some white LEDs. The finished sconces are made from chip-board covered in cherry veneer, all leftover from previous projects.

Want to drink your beer out of beer-byproducts? How about your coffee out of coffee-byproducts. It sounds strange, but 3DOM is marketing it that way, encouraging you to print your beer stein with this beer-byproduct-based 3D printer filament. They also offer coffee filament and have plans for future oddball building materials. Printer inception?

We ran a post about the secret computer of the New York subway system. There wasn’t a ton of information there, but that could change. The New York Historical Society is running a Kickstarter to expand their Computing History made in NY.

Hackaday Prize Entry: Lighting The Way For Walkers

August 20, 2015 by James Hobson 8 Comments

Chances are, you probably know someone who uses a walker to assist in their mobility. Ever wonder about how they could be made better? When [Alan McFarland] noticed his friend using his iPhone as a light to walk down a hallway — with only one hand on his walker — he realized something could easily be done to make the walker more functional. His own light bar.

Sure you could get a flashlight, zip tie it to the walker, or maybe a bike light with a dedicated mount — but [Alan] wanted it to be a bit more elegant; and functional. With this in mind, he attached an LED light strip to the lower frame of the walker to help illuminate the path ahead. A button is wired up to the handle for easy access, and he’s even using a PIC12F1501 microcontroller to give it some logic — it’ll turn off by itself, fading out, giving the person a chance to sit down before the lights go out.

The thing we like about this project is he programmed it using the PICBASIC PRO compiler — the same compiler that [Alan] himself used nearly 20 years ago programming the Borg suits and spacesuit lighting on Star Trek: First Contact — how’s that for a random trivia fact!

[Michael] just missed the deadline for the Trinket Contest but we still think his tablet is pretty cool. He says it predates the iPad and uses a custom aluminum case, a SoC he ripped from a Gecko Edubook, powered by eight NiMH batteries. Check out the front, the guts, and the sides.

Speaking of portable power sources, After doing a teardown of a 12V 6800 mAh Li-Po battery [Howard] strapped some prototyping equipment to either side of it and now he’s got a prototyping power supply that’s easy to take with him.

Blinky goodness doesn’t have to look hacked together (even if it is). This Raspberry Pi logo looks like a professional sign! It was cut from foam and plastic, primed and painted, then stuffed with addressable LED strips.

While we’re on the topic of refined RPi projects, check out this Raspberry Pi MAME cabinet. It’s a bit bigger than the Galaga cabinet we saw recently but still small enough to keep around the house without getting in the way.

If you’re a fan of automotive hacks you should check out this effort to build an Electronic Diesel Control.

We’ve been saving the gnarliest link for last. [Matthew] laments that his missed Halloween to show off this project. But we don’t think an almost-entirely wooden spider-like walker needs to be paired with a holiday. It’s very cool and somewhat operational, but still needs help working out all of the kinks. Our favorite moment in the video is when [Matthew] exclaims “It wants to live!”.

Tweaking Designs For [Theo Jansen] Walking Machines

May 23, 2013 by Mike Szczys 7 Comments

We love the look, and most especially the gait, of [Theo Jansen’s] walker designs. We don’t fully understand them or the math behind them. But that could change if we spend enough time studying [Aaron Birenboim’s] body of work. He wants to incorporate the legs in a project so he’s been trying to optimize the Jansen leg design.

The calculations are delivered in a source code package available from his site. To make heads or trails out of the numbers you need a way to visualize them. He has provided that as well in the form of a MATLAB script which shows leg piece design and can even spit out an animated .gif file of the virtual legs in motion.

If you have no idea what we’re talking about make sure to check out [Jansen’s] original creations. We’re also excited to read more about the Klann and Ghassaei linkage designs which [Aaron] talks about in his post.

Dodecapod To Offset Segway As Futuristic Transport

Who doesn’t love a 12-legged robot, especially if you can ride it around work? You can watch this one running around the patio with rider perched atop it. The machine translation is a bit crude, but it seem this is based on the wicked walking sculptures of [Theo Jansen]. The rider can shift their center of gravity to control the walker, much like a Segway. We’d bet this makes for a rough ride on anything but a smooth level surface, but we’re fine with indoor use only. After all, you’ll need to be close to a charging station as this boasts 45 minutes of juice when transporting a 165 pound operator. See it scurry after the break.

Flatpack Walker

If you’re into robotics, you’re probably already familiar with the 2 motor walker. This design, usually used in B.E.A.M. robotics is a pretty easy way to make a 4 legged walking robot. [Edwindertien] has made the design a little bit easier to build with these flatpack walker plans. He used 4mm thick birch, cut by laser to get his walker into shape, but the design would work with almost any material. His walker is Arduino powered, so it could be programmed for all kinds of behavior, especially if you add some sensors. You can see his bot in action after the break.
