Fashion leads to mind-controlled skirt-lifting contraption

This must be an example of when worlds collide. Who would have thought the geekery of Mindflex and Arduino could make its way into high fashion? But sure enough, this dress transforms based on the mental concentration of the model (must resist urge to crack joke here).

Details are a bit sparse, but you can get a look at the prototype in the video after the break. There’s no nudity; a larger skirt covers a more plain version. That over-skirt is connected to some type of motor system which is driven by an Arduino. When the EEG sensor in the hat detects a certain level of brain wave activity, the outer skirt is lifted and pulled to the back of the outfit, exposing the tighter version beneath.

[Lorenzo] wrote in to share the link to this garment hack. He mentions that a Lilypad and Mindflex are at work here. Looking more into the artist’s website we find this isn’t the only tech-wear produced. There’s a maternity outfit which can sense the baby’s beating heart, and harvest other data about both mother and baby, as well as a few others.

We can’t think this has much future as an everyday outfit, but more utilitarian versions are out there so we think the sky’s the limit on wearable tech.

Control a playlist with your mind

Because switching apps to change a song is such a taxing ordeal, [Oscar Celma] and [Ching-Wei Chen] decided to use their collective brainpower to change Last.FM playlists with their minds. They call their project Buddhafy, and it works by taking off-the-shelf EEG hardware and tying it into music streaming APIs.

For the build, the guys used a NeuroSky MindWave to read alpha waves inside [Oscar]’s head. The data from the MindWave was passed into a Python script that sends requests to the Last.FM and Spotify APIs. High alpha waves in brain wave patterns correspond with concentration or a deep meditative state. If [Oscar] concentrates very hard, he’ll be rewarded with calm and relaxing tunes. If [Oscar] loses focus, the music changes to the best song ever written.

The guys put up the slides from the presentation they gave at MusicHackDay in San Fransisco this last week. There’s also a video of their build in action; you can check that out after the break.

MindFlex watches as you judge others by sight alone

mindflex_headset

[Paul] really wanted to know what his brain was thinking.

No, really. He is aware of all the thoughts that come and go, but he wanted to know what was going on in his brain below his conscious thought stream. Armed with a MindFlex headset and a Teensy, he set out to decode what really was going on inside his head.

He spent a month crawling 35 million Google profiles, downloading each user’s pictures into a MySQL database. The Teensy was attached to the MindFlex sensor board, and collects all of the headset’s output over a serial connection.

His experiment consisted of flashing each of the profile pictures on his monitor for one second, recording 2 of the 11 available brainwave channels from the MindFlex. These values were then plotted out so that he could visualize the “Attention” and “Meditation” values captured by the headset. At the end of the day he discovered, interestingly enough, that looking at dogs relaxed him the most!

We would love to see what correlations could be drawn from his collected data, and what sorts of “hidden” thoughts are coursing through others’ brains. It could certainly end up being a double-edged sword, uncovering subconscious biases and other such things, but it’s an incredibly intriguing experiment to say the least.

Be sure to check out the video below of the experiment in progress.

Controlling fire with your mind (and your thumb)

 

[TechB] is using his mind to control fire. Well, what he’s really doing is using a Mindflex to control a lighter.

Many will remember the Mindflex from this shockingly awesome hack. But [TechB’s] approach follows in the footsteps of this Arduino interface for the device. He’s using the Arduino Brain Library to read data from the head-mounted EEG and sending commands to his own fire control system. Said system is composed of a cigarette lighter and a servo motor. The motor connects to the gas regulator on the lighter, opening it up when you concentrate and closing it when your mind wanders. The result is a higher flame to show more organized brain function. The only problem with the prototype is the burns you’ll get on your thumb from depressing the lighter’s valve while trying to get your thoughts in order.

Check out the video after the break to see this in action. [TechB] is looking a bit like the Borg at the beginning of the clip, making us wonder what other Mindflex hacks he’s already performed.

Brain wave skimming on the go

Mentok: The Mind Taker

Master EEG hackers [MOG] and [Tim] over at the Makers Local 256 have been working on creating a Bluetooth EEG listener made from a Mattel Mindflex. This build is based on an earlier build of a group called [Frontier Nerds] (thanks for the heads up [Nathan]!), but this version ditches the Arduino in favor of a basic serial to bluetooth adapter for the sake of power efficiency (as well as not having to keep an Arduino strapped to you head). We have covered a few Mindflex hacks before, but this seems to be the most useful in a practical sense. They have included the code for a Bluetooth serial data logger, and the earlier build shows a good example of captured data visualization.

Mind controlled TV

Finally, a good use for those EEG headsets. [Andrew] has set up a system that will turn his TV on and off if he focuses hard enough. He’s got the software set to trigger an IR LED when the “strength” gets high enough.  When the action starts, around 4:30 in the video, you can see that when he raises his arm the meter on the screen begins to raise and the TV turns on. Though not immediately useful, we can’t help but get a little excited seeing him literally turn his TV on with a thought.

Hacking the MindFlex, more!

Reader [Eric] sent us a powerfully informative, yet super simple hack for the MindFlex toy. Don’t worry, it’s not another worthless shock ‘game’, And it’s using an actual interface instead of the built-in LEDs.

With two wires for the serial protocol, and an Arduino, you’ll be able to view “signal strength, attention, meditation, delta, theta, low alpha, high alpha, low beta, high beta, low gamma, high gamma” brainwaves. While it’s not medical grade, it’s a lot more intuitive than previous interfaces.

The original intent was for a system called MentalBlock, but we’re wondering what would you do with brainwave data?
