Custom Glove Guides Wearers’ Dreams

For as much advancement as humanity has made in modern medicine even in the last century alone, there’s still plenty we don’t understand about the human body. That’s particularly true of the brain, where something as common as dreams are the subject of active debate about their fundamental nature, if they serve any purpose, and where they originate. One research team is hoping to probe a little further into this mystery, and has designed a special glove to help reach a little deeper into the subconscious brain.

The glove, called Dormio, has a number of sensors and feedback mechanisms which researchers hope will help explore the connection between dreaming and creativity. Volunteers were allowed to take a nap while wearing the glove, which can detect the moment they began entering a specific stage of sleep. At that point, the device would provide an audio cue to seed an idea into the dreams, in this case specifically prompting the sleeper to think about trees. Upon awakening, all reported dreaming about trees specifically, and also demonstrated increased creativity in tests compared to control groups.

While this might not have the most obvious of implications, opening the brain up to being receptive of more creative ideas can have practical effects beyond the production of art or music. For example, the researchers are also investigating whether the glove can help individuals with post-traumatic stress disorder manage nightmares. From a technical perspective this glove isn’t much different from some other devices we’ve seen before, and replicating one to perform similar functions might be possible for most of us willing to experiment on ourselves.

Building Linux Images For ARM Architectures

Want to try your hand at building a Linux package for an embedded device? [SnowBot] decided to give it a try and set out to build Ubuntu for a GumStix. The single-board computer will cost you about $150 to get started, plus a way to connect to the device’s serial port. But once you’ve got your hands on it there is a lot of power in a tiny package.

He’s using the RootStock package to assist in the build. This is a suite of tools that generates the root file system that can be loaded onto an SD card for use with the Gumstix. It’s not quite building from the ground up, but there’s already enough hoops to jump through that this package is a welcomed shortcut.

Already rolling your own Linux packages for embedded hardware? We want to hear about it.

Lucid Dreaming

When we saw [merkz] use of an Arduino to produce lucid dreaming we were quite shocked. Unlike typical setups that just flash a light through sleep, his system monitors eye movement through electrodes and is able to send the data to a computer for graphing and analyzing.  The only problem being we couldn’t find a circuit diagram or code.

Not ones to be shot down so quickly, a Google revealed this thread on making ‘Dream Goggles’, which was really a Brain-Wave Machine based on the parallel port. Some modifications of an ECG collector’s electrodes using sound cards, and you could have your own lucid dreaming.
