Weather-aware Shoe Rack Helps You Get Ready For The Day

August 27, 2016 by Dan Maloney 8 Comments

If you’re anything like us, your complete shoe collection consists of a pair of work boots and a pair of ratty sneakers that need to wait until the next household haz-mat day to be retired. But some people have a thing for shoes, and knowing which pair is suitable for the weather on any given day is such a bother. And that’s the rationale behind this Raspberry Pi-driven weather-enabled shoe rack.

The rack itself is [zealen]’s first woodworking project, and for a serious shoeaholic it’s probably too small by an order of magnitude. But for proof of principle it does just fine. The rack holds six pairs, each with an LED to light it up. A PIR sensor on the top triggers the Raspberry Pi to light up a particular pair based on the weather, which we assume is scraped off the web somehow. [zealen] admits that the fit and finish leave a bit to be desired, but for a first Rasp Pi project, it’s pretty accomplished. There’s plenty of room for improvement, of course – RFID tags in the shoes to allow them to be placed anywhere in the rack springs to mind.

Hackaday Prize Entry: DIY Foot Orthotics

July 1, 2016 by Gerrit Coetzee 7 Comments

What does your gait look like to your foot? During which part of your gait is the ball of your feet experiencing the most pressure? Is there something wrong with it? Can you fix it by adding or removing material from a custom insole? All these answers can be had with an expensive system and a visit to a podiatrist, but if [Charles Fried] succeeds you can build a similar system at home.

The device works by having an array of pressure sensors on a flat insole inside of a shoe. When the patient walks, the device streams the data to a computer which logs it. The computer then produces a heat map of the person’s step. The computer also produces a very useful visualization called a gait line. This enables the orthotist to specify or make the correct orthotic.

[Charles]’s version of this has another advantage over the professional versions. His will be able to stream wirelessly to a data logger. This means you can wear the sensor around for a while and get a much more realistic picture of your gait. Like flossing right before the dentist, many people consciously think about their gait while at the foot doctor; this affects the result.

He currently has a prototype working. He’s not sure how long his pressure sensors will last in the current construction, and he’s put wireless logging on hold for now. However, the project is interesting and we can’t wait to see if [Charles] can meet all his design goals.

Heated Slippers Keep Your Feet Warm, Also Your House As It Burns To The Ground.

March 23, 2015 by Rich Bremer 20 Comments

Winter may be coming to a close but that doesn’t mean that feet are free from being cold. Sure, socks or slippers may help a little, or you can even turn up the heat in your home but none of those options are as fun or as dangerous as [Colin Furze’s] solution. He has come up with some crazy DIY heated slippers.

Sure, there’s battery powered heated slippers or even ones you can microwave to heat up but those are wicked boring. These puppies are actually gas powered and more resemble a small portable camping stove than any sort of footwear. Under each slipper is a custom-made burning chamber inside which is a small burner. Each slipper is supplied a constant flow of fuel from its own on-board gas can. Warming your feet couldn’t be easier, just turn on the gas and light the burner with a match.

It goes without saying but we should reiterate… Don’t try this at home! What you can try is watching the video of these slippers after the break.

[Colin Furze] is not new to having his projects on Hackaday. For more of his flame-based projects, check out his Pyro Gloves. And of course, who could forget these amazing retractable Wolverine Claws.

Nikes With Power Laces, Just In Time For Next Year

October 29, 2014 by Brian Benchoff 21 Comments

With the world’s first hoverboard being shown a few days ago, we’re on the verge of the fabulous world of tomorrow from Back to the Future. Hoverboards are cool, but there’s a wealth of other cool technology from the far-off year of 2015: Mr. Fusions, inflatable pizza, Dustbusters, and of course, Nikes with power laces. [Hunter] just built them, and with the right shoes, to boot.

[Hunter] is using the BttF-inspired Nike Air Mag shoes for this build, along with a few bits of electronics – an Arduino pro mini, a force sensing resistor, and a motor. The build began by carving out a notch in the back of the shoe for the electronics. A small bit of fishing line goes around the shoe, providing the power behind the power laces.

A force sensitive resistor under the heel of the insole tells the microcontroller when a foot is inside the shoe, and a rotary encoder on the motor shaft makes sure all the power lace cycles are the same. It’s not quite the same as the shoe seen on screen – the lower laces can’t be replicated and it’s certainly not as fast as the BttF shoes, but it does work, and as far as shoelaces are concerned, they work well.

Videos below.

Lighted Shoe Ruffles — He’ll Never Step On Your Toes Again

August 9, 2011 by Mike Szczys 11 Comments

Whether for fashion, emergency lighting, or just to make a statement, these lighted shoe clips make for a unique footwear accessory. [Becky Stern], who we’ve seen before hacking automatic knitting machines, tackles this quick lighted project.

The electronics are simple, two LEDs connected in parallel to a button battery by some conductive thread. The circuit is the same as an LED throwie, but she’s using a sewable battery holder. The ruffle is made by cutting out and folding several circles of fabric. We’re not too used to working with this building material and were glad to hear her tip on fusing the cut edges with a lighter. She’s also got a good tip about bending one LED lead in a square shape and the other in a round shape to keep track of the polarity. After sewing everything together and completing the circuit with the conductive thread [Becky] adds a paper clamp making this easy to use with any shoe. In fact, the guy’s don’t have to miss out on the fun as this could easily double as a boutineer.

Don’t miss [Becky’s] complete walk through video embedded after the break.

Haptic GPS Sneakers For The Visually Impaired

April 13, 2011 by Mike Nathan 9 Comments

gps_haptic_shoe

The world can be a pretty difficult place to navigate when you lack the ability to see it. There are many visually impaired people across the globe, with some figures claiming up to 40 million individuals affected. While walking canes and seeing-eye dogs can be a huge help, [Anirudh] of Multimodal Interactions Group, HP Labs India, and some students at the College of Engineering in Pune, India (COEP) have been hard at work constructing a haptic navigation system for the blind.

[Anirudh Sharma and Dushyant Mehta] debuted their haptic feedback shoe design during an MIT Media Lab Workshop hosted at COEP. In its current form, Google Maps and GPS data is sourced from an Android device, which is fed to an Arduino via Bluetooth. The Arduino then activates one of four LEDs mounted on a shoe insert that are used to indicate which direction the individual should travel in order to safely reach their destination. While the current iteration uses LEDs, they will be swapped out for small vibrating motors in the final build.

We’re always fans of assistive technology hacks, and we think this one is great. The concept works well, as we have seen before, so it’s just a matter of getting this project refined and in the ~~hands~~ shoes of those who need it.

Stick around for a quick video about the project filmed at the MIT/COEP event.

Cell Phone Shoe

February 11, 2009 by Caleb Kraft 59 Comments

Sometimes you absolutely need to keep your phone a secret. You know, like when you’re on spy missions. The goons at the door will always frisk you, but they never check under your shoe, right? [mikeyberman] shows us how to make our own Maxwell Smart style shoe phone. All you need is to dig a giant hole in your shoe sole and cram a cell phone in there. Will it get ruined by water? Probably. Will you look like a goon trying to talk on it? Definitely. Can you make it through airport security? Try it and let us know.
