Cosplaying As HAL 9000

November 23, 2014 by Brian Benchoff 11 Comments

2001: A Space Odyssey is one of the greatest films of all time, but unlike every other masterpiece of SciFi, you’re not going find many people cosplaying as characters from the movie. Going as a monolith to a con would be hilarious, but [jacqueslelezard] had an even better idea in mind: a HAL 9000 costume.

The costume itself is just bits of painted cardboard, shiny material (we’d go with aluminum tape), some black mosquito netting to see out of, and in a stroke of brilliance, a tablet that will display HAL’s unblinking eye to con attendees. If you’re extraordinarily clever, it might be possible to sample lines from the movie and play them through the tablet. This is, unfortunately, the best way to replicate the voice of HAL, at least until someone gets the money to have [Douglas Rain] sit in for some voice work.

The only drawback to the costume is the propensity for the wearer to hit their head on doorways and low thresholds. This problem could be solved simply by increasing the size of the costume, but then you’re back in monolith territory. So, what do you want to be, a murderous computer or a galactic swiss army knife?

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.

[Peter] And The Amazing Technicolor Phone Wire Bracelet

October 15, 2014 by Adam Fabio 31 Comments

When a job left him with some extra phone wire, [Peter] didn’t toss it in the scrap pile. He broke out the casting resin and made an awesome bracelet (Imgur link). [Peter] is becoming quite an accomplished jeweler! When we last checked in on him, he was making rings out of colored pencils.

Casting the wire in resin was as simple as building a square form, placing the wires, then filling the form with appropriate amounts of epoxy and hardener. Once the epoxy cured, [Peter] drilled out the center with a sharp Forstner bit. A band saw brought the corners of the block closer to a cylinder.

From there it was over to the lathe, where [Peter] used a jam chuck to hold the bracelet in place. Once he shaped the bracelet [Peter] started wet sanding. It took Lots and lots of sanding both inside and out to finish the bracelet. The result is a mirror smooth finish, with bits of insulation bright copper just popping out of the resin.

One might think that the bracelet would be rough with all that copper, but [Peter] mentions on his Reddit Thread that it feels like plastic, though the bits of copper were “very pokey” before sanding. We’d recommend tossing on a clear coating to protect the exposed copper. Worn on a wrist, all that exposed metal would start oxidizing in no time.

This hack gives us lots of ideas for casting wearable circuits. Some WS2812’s and a teensy would make for a pretty flashy setup! Got an idea for a project? Tell us about in the comments, or post it up on Hackaday.io!

THP Semifinalist: OSHWatch

September 28, 2014 by Brian Benchoff 21 Comments

No, it’s not a finely crafted wrist accessory from Cupertino, but [Jared]’s OSHWatch, but you’re actually able to build this watch thanks to an open design and reasonable, hand-solderable layout.

Built around a case found on DealExtreme that looks suspiciously similar to enclosures meant to hold an iPod Nano, [Jared]’s smartwatch includes a 128×128 RGB OLED display, magnetometer, accelerometer, Bluetooth 4.0 transceiver, and a lithium-ion charger and regulator circuit. Everything is controlled with a PIC24, which should mean this watch has enough processing power to handle anything a watch should handle.

As for the UI and what this watch actually does [Jared] is repurposing a few Android graphics for this watch. Right now, the watch can display the time (natch), upcoming appointments on his schedule, accelerometer and magnetometer data, and debug data from the CPU. It’s very, very well put together, and repurposing an existing watch enclosure is a really slick idea. Videos below.

The project featured in this post is a quarterfinalist in The Hackaday Prize.

A collection of boards that make up the LED Jacket

A Very Bright LED Jacket

September 26, 2014 by Eric Evenchick 6 Comments

Last year, [Ytai] went to Burning Man for the first time. He was a bit inexperienced, and lacked the lumens to make him visible on the Playa. This year, he made up for it by building an extra bright LED Jacket.

The jacket consists of 48 LEDs, at 150 lumens each. Each RGB LED module was placed on its own PCB, and controlled by the tiny PIC12F1571 microcontroller. This microcontroller was a great fit since it has three PWM channels (one for each color) and costs 50 cents. Firmware on the PIC allows the boards to be daisy-chained together to reduce wiring. This was done by using a protocol similar to the popular WS2811 LEDs.

Assembling 50 of the boards presented a challenge. This was addressed by using surface mount components, a solder stencil from OSH Stencils, an electric skillet, and a good amount of patience. The final cost of each module was about $3.

With 50 of the boards assembled, a two layer jacket was sewn up. The electronics were sandwiched between these two fabric layers, which gave the jacket a clean look. A wrist mounted controller allows the wearer to select different patterns.

For a full rundown of the jacket, check out the video after the break.

THP Semifinalist: B10N1C Yourself

September 25, 2014 by Brian Benchoff 46 Comments

The Hackaday Prize has had a few medical devices make the semifinalist cut, and of course wearables are on the list. How about implantables? That’s what Bionic Yourself 2.0 (or B10N1C) is doing with an implantable microcontroller, battery, and sensor system.

The hardware in B10N1C includes a electromyography sensor for measuring muscle activity, an accelerometer, a vibration motor, RFID reader/writer, temperature sensor, and – get this – a LED bar graph that will shine a light through the skin. That’s something we’ve never seen before, and if you’re becoming a cyborg, it’s a nice feature to have.

As with anything you would implant in your body, safety is a prime consideration for Bionic.the Lithium battery can be overcharged (yes, through a wireless charging setup) to 10V without a risk of fire or explosion, can be hit with a hammer, and can even be punctured. The enclosure is medical grade silicone, the contacts are medical grade stainless steel, and there’s a humidity sensor inside that will radio a message saying its time to remove the device if the moisture level in the enclosure increases.

Because the device is implanted under the skin, being able to recharge and update the code without a physical connection is the name of the game. There’s a coil for wireless charging, and a lot of work is going into over the air firmware updating. It’s an astonishing project, and while most people probably won’t opt for a cyborg implant, it will look really cool.

DEFCON Shenanigans: Hack The Hackaday Hat

August 1, 2014 by Mike Szczys 17 Comments

We don’t want to call it a challenge because we fear the regulars at DEFCON can turn our piece of hardware into a smoking pile of slag, but we are planning to bring a bit of fun along with us. I’ll be wearing this classy headgear and I invite you to hack your way into the WiFi enabled Hackaday Hat.

I’ll be wearing the hat-of-many-scrolling-colors around all weekend for DEFCON 22, August 7-10th in Las Vegas. You may also find [Brian Benchoff] sporting the accessory at times. Either way, come up and say hello. We want to see any hardware you have to show us, and we’ll shower you with a bit of swag.

Don’t let it end there. Whip out your favorite pen-testing distro and hack into the hat’s access point. From there the router will serve up more information on how to hack into one of the shell accounts. Own an account and you can leave your alias for the scoreboard as well as push your own custom message to the hat’s 32×7 RGB LED marquee.

You can learn a bit more about the hat’s hardware on this project page. But as usual I’ve built this with a tight deadline and am still trying to populate all the details of the project.
