Cheap Ghostbusters Toy Turned Convincing Prop

March 14, 2022 by 2 Comments

As you might expect, the release of last year’s Ghostbusters: Afterlife has not only lead to renewed interest in the old 1980s toys and tie-in merchandise, but has spawned a whole new generation of blinking plastic gadgets to delight children of all ages. Of course, for folks like us, that means more hardware to hack on.

In a recent post to the official Ghostbusters YouTube channel, professional prop maker [Ben Eadie] shows off some of the tricks of the trade when he takes a $15 USD “PKE Meter” toy from Hasbro and turns it into a screen-quality prop. Even if you’re not looking to get an early start on your Halloween costume, the techniques demonstrated in this video could be easily adapted to other projects. For those whose next ideal home improvement is a fireman’s pole and an ectoplasmic laser-confinement grid, you might want to grab a couple of these toys while they’re still cheap for eventual conversion.

Uncovering the silver makes the piece look worn down.

The biggest takeaway from the video is probably the finishing techniques, as they could be used on any sort of realistic prop build. [Ben] starts by using a cabinet scraper to smooth out the lines on the plastic toy, and any holes are filled with the familiar baking soda and cyanoacrylate glue trick. Once the surfaces have been prepped, all the principle parts are sprayed with an adhesion promoter, followed by a coat of silver, and then the final black color.

This allows him to create a convincing “chipped paint” effect by strategically sanding or scraping through the top coat. Dabbing some toothpaste where you want the device to look worn down before spraying the final coat makes the process even faster, as it will prevent the top coat from sticking to the silver in the first place.

Unfortunately [Ben] doesn’t spend a whole lot of time explaining the electronics side of things, but it doesn’t look like there’s anything too complex going on. All the original gear is stripped, and it gets replaced with a microcontroller which we believe is an Adafruit ItsyBitsy nRF52840 Express. This is connected to two strings of tiny APA102 addressable LEDs which are run down the “wings” (we especially like the 3D printed lenses used to replace the original solid pips), and one that’s used to provide the iconic sine-wave display.

While the last PKE meter build we saw did detect radiation, we have to admit that in terms of looks, this one takes the top spot. Especially when you consider how cheap the thing was. All you need now is a Proton Pack, and you’ll be ready for Halloween.

Larger-Than-Life Game Of Operation Is The Future Of Healthcare

September 21, 2019 by 13 Comments

It’s hard to beat the warm memories of Hasbro’s Operation, a game that boils down the fine art of surgery to removing farcically named plastic bones and organs. Just in case you can’t conjure up the memory, the game board looks just like this huge version of it, but normally  sits flat on the table and is no larger than… well, a board game. Players take turns using a tethered tweezer to remove butterflies from your stomach without touching the metal sides of the incision area. If the tweezers touch the metal, a buzzer goes off and the player loses a turn.

Of course, we now live in the future and robots do our difficult surgeries while the talented doctor looks on from a video console. So, [Ben] and [Jonathan] built themselves an oversized upright version of the game that includes a CNC-wielding surgery robot.

Delightfully, the controls are designed like a coin-op arcade machine and the three-axis CNC machine they’ve built is a new take on the claw machine. It has a gantry that moves left and right, a head that moves up and down along that gantry rail, and an actuator that moves in to snatch those pesky organs. Limit switches cut the power to the motors if the axis moves too far.

Pieces are foam and hang from a coat-hanger hook

In true robosurgery fashion, there’s a webcam that goes along for the ride to give the surgeon a close-up look. Just stay away from those edges! There’s a button on the tip of the actuator that sets off the alarm if you miss the hole and hit the surface of the board, thereby ending your turn. Each organ is made of foam, faced with a piece of sheet metal, and hung from a hook made of coat hanger wire. That sheet metal allows the gripper to use an electromagnet to pick each piece up.

The project is called Sergio and you can see it demonstrated in the video below. We first met these hackers last fall at Maker Faire New York when they were showing off a giant Connect Four game where you play against the computer. It’s nice to hear they’ll be exhibiting Sergio at Philadelphia Maker Faire two weeks from now.

Nerf Mods Via 3D Printing

February 22, 2019 by 2 Comments

Nerf guns are a great way to annoy parents. Simply give them as a gift to any child, and watch precious family heirlooms tumble to the ground as little Holly commando rolls behind the couch to avoid enemy combatants invading the loungeroom. Adults may find them lacking in stopping power and firing rate, but not to worry – there’s plenty to be done about that. [3D Printing Nerd] took a trip to visit the [Out of Darts] workshop, to check out some seriously hardcore blasters.

[Out of Darts] runs as a store that sells all manner of tools and components for hopping up Nerf blasters, but they also sell complete original builds as well. The video showcases all manner of hardware, from powered backpack ammunition hoppers, to drain blaster shotguns and multirocket launchers. The workshop also contains 22 Prusa i3 printers that run 24/7 producing parts, barring breakdowns. Injection moulding, eat your heart out.

Things have come a long way since the old days of swapping in big springs to Hasbro blasters and crossing fingers that nothing breaks. 3D printing allows the home maker to produce just about any part imaginable without requiring advanced machine tools or special skills beyond the use of garden variety CAD software. It’s not the first time we’ve seen 3D printed Nerf blasters, and we’re sure it won’t be the last either. As always, tip ’em if you got ’em. Video after the break.

Mission Impossible: Infiltrating Furby

November 26, 2017 by 9 Comments

Long before things “went viral” there was always a few “must have” toys each year that were in high demand. Cabbage Patch Kids, Transformers, or Teddy Ruxpin would cause virtual hysteria in parents trying to score a toy for a holiday gift. In 1998, that toy was a Furby — a sort of talking robot pet. You can still buy Furby, and as you might expect a modern one — a Furby Connect — is Internet-enabled and much smarter than previous versions. While the Furby has always been a target for good hacking, anything Internet-enabled can be a target for malicious hacking, as well. [Context Information Security] decided to see if they could take control of your kid’s robotic pet.

Thet Furby Connect’s path to the Internet is via BLE to a companion phone device. The phone, in turn, talks back to Hasbro’s (the toy’s maker) Amazon Web Service servers. The company sends out new songs, games, and dances. Because BLE is slow, the transfers occur in the background during normal toy operation.

Furbies Sing Queen At Fresher’s Faire

The University of Kent has their own hacker space, called  [Maker Society]. Every year the school holds an orientation for new students called the Fresher’s Faire. The [Maker Society] display at this year’s Fresher’s Faire included a group of partially clothed Furbies singing the classic Bohemian Rhapsody by Queen. This isn’t our first run in with Bohemian Rhapsody and hacked hardware.

The [Maker Society] started by doing some internet research and reverse engineering a first generation Furby.  The Furby itself is a marvel of cost reduction. All the doll’s functions run from a single motor and a cam system. A limit switch tells the on-board microcontroller when the cam is at the zero position. An optical encoder keeps track of the cam as it moves. The [Society] replaced Furby’s internal microcontroller with an Atmel ATMega328. This allowed them to use the Arduino programming environment.

Many classic Animatronic systems use an audio recording for motion. Typically a stereo recorder would perform double duty. The first track would contain the audio for the animation. A second track would contain audio tones corresponding to movement of each of the degrees of freedom of the doll being animated. Because the two tracks were on the same strip of magnetic tape, the audio and movement would always be in sync. Multitrack tape record and playback systems added even more flexibility to this type of system.

Devote Your Life To Replicating A Lightsaber

August 27, 2010 by 21 Comments

Life-sized Star Wars replica props, it’s one way to keep the ladies away. But if you’re going to make them, you should do it right. [Bradley W. Lewis] spent some serious time getting this [Obi-Wan Kenobi] lightsaber right. The seven-page build log provides plenty of eye-candy. We especially enjoyed the machine and coloring of he grenade-fin portion. The LED ladder that lights the blade is also quite interesting. For the icing on the cake he incorporated a high-performance speaker connected to the sound board from a Hasbro Force FX which provides that classic swashbuckling sound from a galaxy far, far away.
