A Robotic Wheatley Replica created by Evie Bee

Robotic Wheatley From Portal 2

November 30, 2015 by Eric Evenchick 7 Comments

It’s been over 4 years since Portal 2 launched, but Wheatley, the AI character with a British accent, remains a captivating character. [Evie Bee] built a Wheatley replica complete with sound, movement, and one glowing eye.

The body of Wheatley is made out of blue insulation foam, also called XPS foam, laminated together with UHU Polyurethane glue. This formed a sphere, which was then cut into a detailed body. Papier mache clay was used to strengthen the thin foam.

The electronics for this build provide light, motion, and sound. The eye is moved by a total of 3 Arduino controlled servos: two for the movement of the eye, and one to allow it to open and close. Movement is controlled by two joysticks. Sound is provided by the Adafruit Sound Board, which connects to a speaker and a Velleman Sound to Light Kit. This kit controls the LEDs that light the eye, making it react to the voice of Wheatley.

You can watch this Wheatley rant at you after the break. Of course if you’re going to have a Wheatley you need a GLaDOS potato as well.

Development Tools Of The Prop-Making World

November 9, 2015 by Sonya Vasquez 13 Comments

We’ve seen them before. The pixel-perfect Portal 2 replica, the Iron Man Arc Reactor, the Jedi Lightsaber. With the rise of shared knowledge via the internet, we can finally take a peek into a world hidden behind garage doors, basements, and commandeered coffee tables strewn with nuts, bolts, and other scraps. That world is prop-making. As fab equipment like 3D printers and laser cutters start to spill into the hands of more people, fellow DIY enthusiasts have developed effective workflows and corresponding software tools to lighten their loads. I figured I’d take a brief look at a few software tools that can open the possibilities for folks at home to don the respirator and goggles and start churning out props.

Unplayable Holophonor Replica Is Unplayable

holophonor

You won’t find all that many props or homemade replica builds here at Hackaday, but [Harrison Krix’s] work is second to none, and his Futurama Holophonor replica is worth drooling over. [Harrison] sourced an old (and apparently grimy) clarinet from a local thrift store, which he strips clean of its keys and attachments. The body itself receives some subtle modifications from the lathe and epoxy to plug some holes. Custom-spun plastic pieces complete the rest of the body, including the meticulously crafted bell which houses 54 LEDs.

[Harrison] also whips up a breakout board for a mini Arduino Pro with 4 fading and 4 blinking channels, and some custom power supply options for the Holophonor’s base: a scratch-built fiberglass AAA battery holder and optional AC adapter jack. As an added bonus, he’s fitted the Holophonor’s stand with a set of Robot Devil hands that hold it in place. The only video is an illumination test, but it sure is pretty. You can see it below! It looks perfect, but alas is unplayable which actually makes it even more authentic.

The Holophonor is the latest in a slew of work from Volpin Props. You probably remember [Harrison’s] first Daft Punk helmet from a few years back, or the second one that followed shortly after.

How To Build A Vacuum Form Table That Gets It Right Every Time

August 31, 2011 by Mike Nathan 27 Comments

[James] builds all sorts of robots and superhero costume replicas at home, so he is always searching for a better way to get consistent results when using his vacuum table. A lot of people use their oven or exposed heating coils from electric frying pans to warm the plastic sheets, but [James] wasn’t really interested in going down that route. He cites that he would rather not heat plastic in the oven where he cooks his food, nor is he really keen on the idea of exposed heating elements.

Instead, he opted for a slightly pricier, though completely reasonable setup that produces consistent results every time. Most of the forming table was built using MDF sheeting, as you can see in the video below. His heating apparatus was the most expensive part of the rig, since it’s an off the shelf quartz-based room heater. He lays the heater on its back side, and directs the heat up through an MDF frame using aluminum foil as a reflector. The plastic sheeting mounted at the top heats evenly, and in no time, he has a perfectly vacuum formed prop that is ready to be painted.

Sure, it might cost a bit more than some other vacuum formers we’ve looked at before, but spending a bit more up front to get consistent results is well worth it if you ask us.
