Making Crampons Out Of Scrap

April 17, 2019 by 17 Comments

If you’re living somewhere that gets icy in the wintertime, you know the sidewalk can be perilous. Slipping on ice hurts like hell if you’re lucky, and can cause serious injuries if you’re not. Naturally, if you’re trying to get down to the hackerspace when it’s cold out, you’ll look for solutions. [masterbuilder] wanted to be surefooted in the coming season, and decided to build a set of crampons.

Scrap inner tubes are the key here, providing a source of hardy rubber for the build. The tubes are cut into a series of bands which are woven together in a hexagonal pattern. Steel nuts are included at various points to help grip the ice in inclement conditions. A larger strip of rubber is then used to form a band which secures the entire assembly to the wearer’s shoes.

It’s a design that’s intended for ease of use over outright performance. The crampons can be quickly attached and removed, and using nuts instead of spikes reduces the chance of damaging the floor if you forget to take them off immediately when returning home. If you’ve got any handy winter hacks of your own, you know where to send ’em.

Only 90s Kids Want Heelys Made From Pallet Wood

April 14, 2019 by 7 Comments

The kids are simply cooler than you. While you’re walking around using your feet like an animal, kids have shoes with wheels in their heels. These are called Heelys, and here’s how you make wooden clogs, with wheels in the heels, out of pallet wood. If you have to ask why, you’ll never know.

This build started off with a fairly large maple log, which would be the traditional way to build clogs. After taking this log to the bandsaw and looking inside, [Jackman] found a bit of spalting, or arguably aesthetically pleasing fungal growth. Whether the spalting would look good or not is a matter for debate, but either way [Jackman] decided to change plans and moved over to creating pallet wood clogs. A word of warning about pallet wood: you shouldn’t make anything out of wood from discarded pallets unless you know what you’re doing, and even if you do know what you’re doing there will be someone in the comments telling you that you shouldn’t use wood from discarded pallets. You can check out the comments to this article to verify this fact.

The construction of the clogs started with a few pieces of one inch stock glued up into a gigantic block, then several pieces of half inch stock resawn into quarter inch stock and laminated onto the sole of the clog. This was then shaped using a variety of tools from Arbortech; of note, we have the Turbo Plane, a wood shaping tool for a grinder that sounds more dangerous than it is, the Turbo Shaft, a plunge router or mortiser-sort-of-thing for a grinder that’s much cooler than it sounds, and the Power Chisel, something we can’t even believe exists and hold on here’s all our money.

These tools couldn’t get all the way into the toe of the clog, which meant [Jackman] had to saw down the middle and hollow everything out that way, but this did give him a nice flat surface on the inside to install the Heely wheels. This turns the clogs into something nine-year-olds simultaneously desire and don’t appreciate, because they’re kids.

3D Printed Sneakers Are Now A Thing

October 5, 2018 by 20 Comments

Shoes may seem simple at face value, but are actually rather complex. To create a comfortable shoe that can handle a full day of wear without causing blisters, as well as deal with the stresses of running and jumping and so on, is quite difficult. Is it possible to create a shoe that can handle all that, using a 3D printer?

[RCLifeOn] discovered these sneakers by [Recreus] on Thingiverse, and decided to have a go printing them at home. While [Recreus] recommend printing the shoes in their Filaflex material, for this build, one shoe was printed in thermoplastic polyurethane, the other in Ninjaflex. As two filaments that are both commonly known to be pliable and flexible, the difference in the final parts is actually quite significant. The Ninjaflex shoe is significantly more flexible and cushions the foot better, while the rigidity of the TPU shoe is better for ankle support.

Our host then takes the shoes on a long run through the woods, battling dirt, mud, and other undesirables. Both shoes hold up against the abuse, although [RCLifeOn] notes that the Ninjaflex shoe is much more comfortable and forgiving for longer duration wear.

We’ve seen other 3D printed shoe hacks before, too – like these nifty shoelace locks.

Hackaday Prize Entry: Open Bike Shoe

November 2, 2017 by 24 Comments

Shoes are some of the most complex pieces of equipment you can buy. There’s multiple materials ranging from foam to weird polyesters in a simple sneaker, and if you dig into shoes for biking, you’ll find some carbon fiber. All these layers are glued together, stitched, and assembled into a functional piece of exercise equipment, with multiple SKUs for each size. It’s really amazing.

Accordingly, [marcs] created N+ Open Bike Shoe Platform, the purpose of which is to create open source,  customizable, and repairable shoe platform based on 3D printing, though with other techniques like rubber molding and sewing fabric uppers are included as well.

The project breaks down its signature shoe into all its various parts: heel, toe tread, insole, upper, and so on. With each part individually customizable, the shoe can be tailored to suit each individual, all while part of a cradle-to-grave lifecycle that allows shoe parts to be replaced, repaired, or recycled.

Shoelace Locks Keep Your Fancy Footwear Firmly Attached

April 9, 2017 by 25 Comments

Remember the 1980s, when velcro sneakers were the hip new thing? (Incidentally, VELCRO® is a registered trademark for VELCRO® brank hook-and-loop fasteners but we use it here as a general term for the fastening technology). Only the coolest kids in school had a fresh pair of Zips. Velcro left a bit to be desired though. The hooks and loops would wear out, and the sneakers always seemed to pop apart at the worst possible moments — like when running or jumping. These days, velcro seems to be relegated to the elderly, which gives it the stigma of “old people shoes”.

So what is an aspiring hacker to do, just tie their shoelaces like a simple plebe? [Pentland_Designs] has the answer with his shoelace locks. The design is his take on the classic plastic clip found on backpacks and jackets. [Pentland_Designs] has added a twist though — a “button” which flexes a plastic ring, releasing the main body of the clip. This means the user doesn’t have to bend down when taking off their shoes. This isn’t just good for folks with disabilities. Anyone with back problems will tell you that avoiding a couple of deep bends at the end of the day helps a lot.

Check out the video of [Pentland_Designs] Shoelace locks after the break. For more shoe-tech, check out these LEGO self-lacing shoes, or this teardown of Nike’s self-lacing offering.

Scissor Lift Shoes May Be OSHA Compliant

January 7, 2017 by 30 Comments

It’s been said that necessity is the mother of all invention. This was probably the fundamental principle behind the show “Inspector Gadget”, a story about a police agent who has literally any technology at his grasp whenever he needs it. Although the Inspector’s gadgets get him into trouble more often than not (his niece Penny usually solves the actual crimes), the Inspector-inspired shoes that [Make it Extreme] built are a little bit more useful than whatever the Inspector happens to have up his sleeve (or pant leg, as the case may be).

If a fabrication tour de force, [Make it Extreme] built their own “Go Go Gadget Legs”, a set of pneumatically controlled stilts that allow the wearer to increase their height significantly at the push of a button. We often see drywall contractors wearing stilts of a similar height, but haven’t seen any that are able to raise and lower the wearer at will. The team built the legs from scratch, machining almost every component (including the air pistons) from stock metal. After some controls were added and some testing was done, the team found that raising one foot at a time was the safer route, although both can be raised for a more impressive-looking demonstration that is likely to throw the wearer off balance.

The quality of this build and the polish of the final product are incredibly high. If you have your own machine shop at home this sort of project might be within your reach (pun intended). If all you have on hand is a welder, though, you might be able to put together one of [Make it Extreme]’s other famous builds: a beer gun.

The E-Traces Shoes

Visualizing Ballet Movements With E-Traces

November 15, 2015 by 5 Comments

When we think of wearable technologies, ballet shoes aren’t the first devices that come to mind. In fact, the E-Traces pointé shoes by [Lesia Trubat] may be the first ever “connected ballet shoe.” This project captures the movement and pressure of the dancer’s feet and provides this data to a phone over Bluetooth.

The shoes are based on the Lilypad Arduino clone, which is designed for sewing into wearables. It appears that 3 force sensitive resistors are used as analog pressure sensors, measuring the force applied on the ground by the dancer’s feet. A Lilypad Accelerometer measures the acceleration of the feet.

This data is combined in an app running on an iPhone, which allows the dancer to “draw” patterns based on their dance movements. This creates a video of the motion based on the dance performed, and also collects data that can be used to analyze the dance movements after the fact.

While these shoes are focused on ballet, [Lesia] points out that the same technique could be extended to other forms of dance for both training and visualization purposes.
