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.

In recent years, Cosplay as a hobby has seen improvement in the props department by leaps and bounds. Thanks in part due to the rise of the Maker culture and the easy availability of design and manufacturing tools and processes. Case in point is this awesome set of Animatronic Wings that programmer [Nelson Stoldt] built for his daughter who wanted to be Nightmare Moon.
[Nelson] had no idea what he’d gotten himself in to when he answered “Sure, I can do that”. Making motorized cosplay wings that open up to 8 feet wide and close again at the flick of a switch without weighing a ton is not a trivial project. The final rig did end up tipping the scales at just over 9 kgs, but we guess that’s a load that Cosplayers are used to hauling around.
Using a nifty program called Linkage, he played around with a few different design approaches until he found a mechanism that worked well. If you ever want to build one of [Theo Jansen]’s Strandbeest, give this program a spin. Armed with this information, and a spreadsheet to help determine the exact length of each linkage element, he modelled the project in Sketchup. The wings are operated by a scissor mechanism that is driven by a motorized screw operated sliding carriage. Wing position is measured by a potentiometer coupled to one of the wing elements. Basically, he just built a huge, powerful servo.

Today Pebble has announced that it will cease all hardware production. Their outstanding Kickstarter deliveries will not be fulfilled but refunds will be issued. Warranties on all existing hardware will no longer be honored. However, the existing smartwatch service will continue… for now.
This isn’t unexpected, we ran an article yesterday about the all-but-certain rumors FitBit had acquired Pebble (and what led to that). Today’s news has turned speculation about Pebble 2 and Pebble Core Kickstarter campaigns into reality. You won’t get your hands on that fancy new hardware, but at least backers will have the money returned.
Perhaps the most interesting part of today’s blog post from the founder of Pebble, Eric Migicovsky, is about how this impacts more than a million watches already in the wild. Service will continue but (wait for it) “Pebble functionality or service quality may be reduced in the future.”
It’s not like this is a unique problem. Devices purchased by consumers that are dependent on phoning home to a server to function is a mounting issue. Earlier this year [Elliot Williams] coined this issue “Obsolescence as a Service” which is quite fitting. Anyone who still has a functional first generation iPad has enjoyed reduced quality of service; without available upgrades, you are unable to install most apps. It’s zombie hardware; electrons still flow but there’s no brain activity.
One of the perks associated with FitBit acquiring Pebble is that they have decided to keep those servers running for watches in the field. A cynic might look at the acquisition as FitBit reducing competition in the market — they wouldn’t have let hardware production cease if they were interested in acquiring the user base. At some point, those servers will stop working and the watches won’t be so smart after all. FitBit owns the IP which means they could open source everything needed for the community to build their own server infrastructure. When service quality “reduced in the future” that’s exactly what we want to see happen.
At the 2016 Hackaday Superconference, Amanda Brief and Jacob McEntire gave a talk on what they’ve been working on for the past few years. It’s My.Flow, the world’s first tampon monitor capable of tracking saturation, and eliminating anxiety, leakage, and infection. It’s better than a traditional tampon, and it’s one of the rare Internet of Things things that actually makes sense.
There’s a long history of technological innovation to deal with menstruation. What began with simply sending women out of the village for a week turned into a ‘sanitary belt’ after a few thousand years. This astonishing technological advance of treating women as people led to the pad, the cup, and eventually, the disposable tampon. Now My.Flow is applying modern electrochemical technology to move the state of the art forward.

Despite owning five, including the original Pebble, I’ve always been somewhat skeptical about smart watches. Even so, the leaked news that Fitbit is buying Pebble for “a small amount” has me sort of depressed about the state of the wearables market. Because Pebble could have been a contender, although perhaps not for the reason you might guess.
Pebble is a pioneer of the wearables market, and launched its first smartwatch back in 2012, two years before the Apple Watch was announced. But after turning down an offer of $740 million by Citizen back in 2015, and despite cash injections from financing rounds and a recent $12.8 million Kickstarter, the company has struggled financially.
An offer of just $70 million earlier this year by Intel reflected Pebble’s reduced prospects, and the rumoured $30 to $40 million price being paid by Fitbit must be a disappointing outcome for a company that was riding high such a short time ago.

Smartwatches are pretty great. In theory, you’ll never miss a notification or a phone call. Plus, they can do all kinds of bio-metric tracking since they’re strapped to one of your body’s pulse points. But there are downsides. One of the major ones is that you end up needing two hands to do things that are easily one-handed on a phone. Now, you could use the tip of your nose like I do in the winter when I have mittens on, but that’s not good for your eyes. It seems that the future of smartwatch input is not in available appendages, but in gesture detection.
Enter WristWhirl, the brain-child of Dartmouth and University of Manitoba students [Jun Gong], [Xing-Dong Yang], and [Pourang Irani]. They have built a prototype smartwatch that uses continuous wrist movements detected by IR proximity sensors to control popular off-the-shelf applications. Twelve pairs of dirt-cheap IR sensors connected to an Arduino Due detect any of eight simple gestures made by the wearer to do tasks like opening the calendar, controlling a music player, panning and zooming a map, and playing games like Tetris and Fruit Ninja. In order to save battery, a piezo senses pinch between the user’s thumb and forefinger and uses this input to decide when to start and stop gesture detection.
According to their paper (PDF warning), the gesture detection is 93.8% accurate. To get this data, the team had their test subjects perform each of the eight gestures under different conditions such as walking vs. standing and doing either with the wrist in watch-viewing position or hanging down at their side. Why not gesture your way past the break to watch a demo?
If you’re stuck on the idea of playing Tetris with gestures, there are other ways.

Your eyes are cool, but they aren’t very loud. You can remedy that with this build from [Sam Freeman]: a pair of Bluetooth speaker goggles. Combine a pair of old welders goggles with a Bluetooth receiver, a small amp and a couple of cheap speaker drivers and you’re well on your way to securing your own jet set radio future.
[Sam] found a set of speaker drivers that were the same size as the lenses of the goggles, as if they were designed for each other. They don’t do much for your vision, but they definitely look cool. [Sam] found that he could run the speakers for an hour or so from a small Lithium Ion battery that’s hidden inside the goggles, along with a large lever switch for that throwback electronics feel. The total cost of this build is a reasonably-low at $40, or less if you use bits from your junk pile.
The real trick is watching them in action and deciding if there’s any motion happening. Don’t get us wrong, they look spectacular but don’t have the visual feedback component of, say, the bass cannon. Look for yourself in the clip below. We might add a pair of googly eyes on the speakers that dance as they move, but that would get away from the more serious Robopunk look that [Sam] is going for. What would you add to build up the aesthetic of these already iconic goggles?
