Barbie’s Video Has Never Looked So Good

October 8, 2024 by Jenny List 8 Comments

For those who missed it, there’s been something of a quiet revolution in the world of analogue video over the last year, due to the arrival of inexpensive “MiniDVR” devices. These little modules are a complete video recorder including battery, recording PAL or NTSC composite video and audio to SD card. They’ve become the box of choice for camcorder enthusiasts, but that’s not where the fun ends. [Max Vega] has taken a Barbie video camera toy from 2001 and added a MiniDVR to make it into a fully self-contained novelty camcorder. But this isn’t a simple case of duct-taping the DVR to the toy, instead it’s a comprehensive upgrade resulting in a device which could almost have been a real product.

The original toy had a small transmitter which could send over a short distance to a receiver that connected to a domestic VCR, so all that circuitry had to go. The camera itself is a small enough module in the fake lens assembly, with an easily identifiable output cable with the required composite signal. The video below the break steps through the proces of making the space for the MiniDVR module, and putting in extensions for all its buttons, and the SD card. Finally it has a new power supply module with an associated USB-C input, providing juice to both DVR and camera.

The result has what we can only describe as a pleasingly retro feel, in that it’s not of high quality and the colour is, well, Never The Same. But when a smartphone can record HD video that’s not the point, instead it’s there to be a retro toy, and in that it succeeds completely.

Sushi-Snarfing Barbie Uses Solenoid To Swallow

August 7, 2018 by Kristina Panos 15 Comments

The view from America has long seen French women as synonymous with thin and/or beautiful. France is well-known for culinary skill and delights, and yet many of its female inhabitants seem to view eating heartily as passé. At a recent workshop devoted to creating DIY amusements, [Niklas Roy] and [Kati Hyyppä] built an electro-mechanical sushi-eating game starring Barbie, American icon of the feminine ideal. The goal of the game is to feed her well and inspire a happy relationship with food.

Built in just three days, J’ai faim! (translation: I’m hungry!) lets the player satiate Barbie one randomly lit piece of sushi at a time. Each piece has a companion LED mounted beneath the surface that’s connected in series to the one on the game board. Qualifying sushi are determined by a photocell strapped to the underside of Barbie’s tongue, which detects light from the hidden LED. Players must race against the clock to eat each piece, taking Barbie up the satisfaction meter from ‘starving’ to ‘well-fed’. Gobble an unlit piece, and the score goes down.

The game is controlled with a lovely pink lollipop of a joystick, which was the main inspiration for the game. Players move her head with left and right, and pull down to engage the solenoid that pushes her comically long tongue out of her button-nosed face. Barbie’s brain is an Arduino Uno, which also controls the stepper motor that moves her head.

[Niklas] and [Kati] wound up using cardboard end stops inside the box instead of trying to count the rapidly changing steps as she swivels around. The first motor they used was too weak to move her head. The second one worked, but the game’s popularity combined with the end stops did a number on the gears after a day or so. Click past the break to sink your teeth into the demo video.

Barbie can do more than teach young girls healthy eating habits. She can also teach them about cryptography.

Crypto Features: They’re Not For Girls

December 5, 2016 by Jenny List 56 Comments

If you have worked in an office that contained a typewriter, the chances are you’ve been in the workplace for several decades. Such has been the inexorable advance of workplace computing. It’s a surprise then to discover that one of the desirable toys from many decades ago, the Barbie Typewriter, is still available. Are hipster parents buying toy versions of vintage office machinery for their children to use in an ironic fashion?

Gone though are the plastic versions of mechanical typewriters that would have been the property of a 1970s child. The modern Barbie typist has an electronic typewriter at her fingertips, with a daisy-wheel printer. We’re treated to a teardown of the recent models courtesy of Crypto Museum, who reveal a hidden feature, Barbie’s typewriter can encrypt and decrypt messages.

Now the fact that a child’s toy boasts a set of simple substitution cyphers is hardly the kind of thing that will set the pulses of Hackaday readers racing, after all simple letter frequency analysis is hardly new. But of course, the Crypto Museum angle is only part of this story.

This toy is made in a suitably eye-watering shade of pink, and sold by Mattel with Barbie branding. But it didn’t start life as a Barbie product, instead it’s licensed from the Slovenian manufacturer Mehano. The original toy makes no secret of the crypto functions, but though they persist in the software on the Barbie version they are mysteriously absent from the documentation. The achievements of American women are such that they have given us high-level languages and compilers, or their software has placed men on the Moon, yet it seems when they are young a brush with elementary cryptology is beyond them in the way that it isn’t for their Slovenian sisters. This is no way to nurture a future Grace Hopper or Margaret Hamilton, though sadly if your daughter is a Lisa Simpson this is just one of many dumbed-down products she’ll be offered.

If you see a Barbie electronic typewriter in a yard sale or similar, and you can pick it up for a few dollars, buy it. It’s got a simple daisywheel printer mechanism that looks eminently hackable. Just don’t buy it for your daughter without also printing out the Crypto Museum page for her as the missing manual.

When the Martian lander running her code has touched down safely, you’ll be glad you did.

Rita’s Dolls Probably Live Better Than You Do

September 6, 2016 by Gerrit Coetzee 3 Comments

If it wasn’t for the weird Dutch-Norwegian techno you’d presumably have to listen to forever, [Gianni B.]’s doll house for his daughter, [Rita] makes living in a Barbie World seem like a worthwhile endeavor. True to modern form, it’s got LED lighting. It’s got IoT. It’s got an app and an elevator. It even has a tiny, working, miniature television.

It all started with a Christmas wish. [Rita] could no longer stand to bear the thought of her Barbie dolls living a homeless lifestyle on her floor, begging passing toys for enough monopoly money to buy a sock to sleep under. However, when [Gianni] visited the usual suspects to purchase a dollhouse he found them disappointing and expensive.

So, going with the traditional collaborating-with-Santa ruse, he and his family had the pleasure of collaborating on a dollhouse development project. Each room is lit by four ultra bright LEDs. There is an elevator that’s controlled by an H-bridge module, modified to have electronic braking. [Rita] doesn’t own a Dr. Barbie yet, so safety is paramount.

The brain of the home automation is a PIC micro with a Bluetooth module. He wrote some code for it, available here. He also went an extra step and used MIT’s scratch to make an app interface for the dollhouse. You can see it work in the video after the break. The last little hack was the TV. An old arduino, an SD Card shield, and a tiny 2.4 inch TFT combine to make what’s essentially a tiny digital picture frame.

His daughter’s are overjoyed with the elevation of their doll’s economic class and a proud father even got to show it off at a Maker Faire. Very nice!

“Hello Barbie” Not An IoT Nightmare After All

January 29, 2016 by Elliot Williams 25 Comments

Security researchers can be a grim crowd. Everything, when looked at closely enough, is insecure at some level, and this leads to a lot of pessimism in the industry. So it’s a bit of a shock to see a security report that’s filled with neither doom nor gloom.

We’d previously covered Somerset Recon’s initial teardown of “Hello Barbie” and were waiting with bated breath for the firmware dump and some real reverse engineering. Well, it happened and basically everything looks alright (PDF report). The Somerset folks desoldered the chip, dumped the flash ROM, and when the IDA-dust settled, Mattel used firmware that’s similar to what everyone else uses to run Amazon cloud service agents, but aimed at the “toytalk.com” network instead. In short, it uses a tested and basically sound firmware.

The web services that the creepy talking doll connected to were another story, and were full of holes that were being actively patched throughout Somerset’s investigation, but we were only really interested in the firmware anyway, and that looked OK. Not everything is horror stories in IoT security. Some stories do have a happy ending. Barbie can sleep well tonight.

Who’s Watching The Kids?

It wasn’t long ago that we saw the Echo bloom into existence as a standalone product from its conceptual roots as a smartphone utility. These little black columns have hardly collected their first film of dust on our coffee tables and we’re already seeing similar technology debut on the toy market, which causes me to raise an eye-brow.

There seems to be some appeal towards making toys smarter, with the intent being that they may help a child learn while they play. Fair enough. It was recently announced that a WiFi enabled, “Hello Barbie” doll will be released sometime this Fall. This new doll will not only be capable of responding to a child’s statements and questions by accessing the Internet at large, it will also log the likes and dislikes of its new BFF on a cloud database so that it can reference the information for later conversations. Neat, right? Because it’s totally safe to trust the Internet with information innocently surrendered by your child.

Similarly there is a Kickstarter going on right now for a re-skinned box-o-internet for kids in the shape of a dinosaur. The “GreenDino”, is the first in a new line called, CogniToys, from a company touted by IBM which has its supercomputer, Watson, working as a backbone to answer all of the questions a child might ask. In addition to acting as an informational steward, the GreenDino will also toss out questions, and upon receiving a correct answer, respond with praise.

Advancements in technology are stellar. Though I can see where a child version of myself would love having an infinitely smart robot dinosaur to bombard with questions, in the case of WiFi and cloud connectivity, the novelty doesn’t outweigh the potential hazards the technology is vulnerable to. Like what, you ask?

Whether on Facebook or some other platform, adults accept the unknown risks involved when we put personal information out on the Internet. Say for instance I allow some mega-corporation to store on their cloud that my favorite color is yellow. By doing so, I accept the potential outcome that I will be thrown into a demographic and advertised to… or in ten years be dragged to an internment camp by a corrupt yellow-hating government who subpoenaed information about me from the corporation I consensually surrendered it to.

The fact is that I understand those types of risks… no matter how extreme and silly they might seem. The child playing with the Barbie does not.

All worst case scenarios of personal data leakage and misuse aside, what happens when Barbie starts wanting accessories? Or says to their new BFF something like, “Wouldn’t we have so much more fun if I had a hot pink convertible?”

Don’t Blink, Ken… Or The Weeping Barbie Will Get You

July 3, 2014 by Rick Osgood 43 Comments

WeepingBarbies — That which holds the image of an Angel becomes itself an Angel. Have fun with that.

Barbie dolls have been around since 1959, but never before have they been this terrifying. [anthropolywog] decided to kick the creepy factor up a notch by modifying some poor, defenseless Barbie dolls into weeping angels.

If you aren’t familiar with the weeping angel concept, you probably don’t watch Dr. Who. The weeping angel episode, titled “Blink“, is now considered a classic Dr. Who episode. The basic premise is that some creepy, weeping stone statues can move only when no one is looking at them. Even closing your eyes for a moment to blink is enough to get them to move. It’s actually quite terrifying, but also awesome.

[anthropolywog] started by purchasing several ordinary Barbie dolls. She then cut off all of the arms at the elbow. This is because the Barbie arms do not normally bend at the elbow, and this was required to get that classic weeping angel pose. The hair was glued up into a bun, similar to the weeping angels from the show. The Barbies were then hot glued to wooden stands to make it easier to work on them.

Crinkle cotton fabric was then cut into a simple dress shape and draped over the dolls. The entire doll was then sprayed with a mixture of Elmer’s glue and water. This stiffens up the fabric and makes the whole thing look more statuesque.

The most complicated part was the wings. [anthropolywog] hand-made the wings from cardboard and craft feathers. This process took several hours of work in order to get something that would look right.

The dolls were primed for paint separately from the wings. The wings were then attached, and the whole doll was painted with “natural stone” textured spray paint. The final touch was to re-draw the faded eyes and mouths with a fine tipped permanent marker. You can see in the photo that the result turned out very well.
