Over the past few years, we’ve seen [Michael]’s adventures in electronics and lucid dreaming. With commercial EEG hardware, [Michael] is able to communicate from inside his dreams with Morse code and record his rhythmic blinking for data analysis when he wakes up. His project is called Lucid Scribe, and now it’s open to just about everyone – including brain experimenters with OpenEEG hardware.
OpenEEG is a project that aims to reduce the cost of EEG hardware by providing the hardware, electrodes, software, and documentation to build your own EEG headset. It’s a great tool in the field of biofeedback, but [Michael] is going one step further; he’s busy writing an algorithm that will detect REM sleep and play an audio track while he’s in a dream state to trigger a lucid dream.
[Michael] points out that anyone with OpenEEG hardware including the DIY Olmex board can contribute to his Lucid Scribe database. You might also get some lucid dreaming time in, but then you’ll have to wake to the crushing reality of real life.
The members of Shackspace continue to put up impressive hacks based around the tiny TP-Link routers. This time around [Timm] has shoehorned a DALI controller inside the router case. This is a protocol we don’t remember hearing about before. The Digital Addressable Lighting Interface is a control network for commercial lighting. That way people responsible for taking care of large buildings can shut off all the lights at night (to name just one use). The new room at Shackspace has this style of controllers in its lights.
The two brown wires coming into the router make up the data bus for the DALI system. It connects to the add-on PCB which uses an Atmel AT90PWM316 microcontroller. The chip is specifically designed for DALI networks which made the rest of the project quite easy. It talks to the lights, the router talks to it, bob’s your uncle, and you’ve got network controlled lighting. Get this in a big enough building and you can play some Tetris.
In case you were wondering. Yes, this project has already been added to their TP-Link firmware generator.
The round-about way this iPhone garage door opener was put together borders on Rube Goldberg. But it does indeed get the job done so who are we to judge? Plus you have to consider that the Apple products aren’t quite as hacker friendly as, say, Android phones — so this may have been the easiest non-Jailbreak way.
The main components that went into it are the iPhone, a Wemo WiFi outlet, and a 110V rated mechanical relay. But wait, surely it can’t be that simple? You’re correct, just for added subterfuge [Tall-drinks] rolled IFTTT into the mix.
You may remember hearing about If This Then That from the Alert Tube project. It’s a web-based natural language scripting service. Throw everything together and it works like this: The iPhone sends a text message which IFTTT converts to a Wemo command. A power cord connects the Wemo outlet to the 110V electrodes on the relay. The normally open connection of the relay is attached to the same screw terminals of the garage door opener as the push button that operates it. When the relay closes, the garage door goes up or down.
The biggest problem we have with this is the inability to know if your garage door is open or closed.
The Advent of the Raspberry Pi has seen an explosion in the market for ARM dev boards, sometimes even with pinouts for Arduino shields. The UDOO, though, takes those boards and ramps up the processing power for some very, very interesting builds.
The UDOO comes equipped with a dual or quad-core ARM CPU running at 1GHz with 1 GB of RAM. Also on board is the Atmel SAM3X8E – the same chip in the new Arduino DUE – and has pinouts for all those Arduino shields you have lying around.
In addition to serving your next project as a souped-up Raspberry Pi, UDOO also includes 78 (!) GPIO pins, Gigabit Ethernet, a camera connector, one SATA port (on the quad-core version), and an LVDS header for attaching LCD monitors. Basically, the UDOO is the motherboard of an ARM-powered laptop with the pinouts to handle Arduino shields. It’s just like [Bunnie]’s laptop, only this time you can actually buy it.
The UDOO doesn’t come cheap, though: on the UDOO Kickstarter, the dual-core version is going for $150 while the quad-core is priced at $170. Still, if you need the power to run a pair of Kinects or want to build an awesome torrent box, you’d be hard pressed to find a more powerful board.
[Dynotronix] wrote in to share the news that he won the 2013 LayerOne badge hacking contest. In addition to the good news he included a description of his badge hack.
We got a good look at the hardware included on the badge several days ago. You may remember that it’s outfitted with footprints for 48 LEDs around the perimeter which are driven by two ICs. Looking at the image above it’s hard to miss the fact that [Dyno] didn’t populate any of that. He went right for the power of the XMEGA processor to analyze and generate signals.
But what specifically can you do with the signal this thing generates? Turns out a rather simple circuit can make it into a transmitter. [Dyno] concedes that it’s a remarkably finicky setup, but just a few components on a scrap of copper clad turned this into an FM transmitter. Check out the video where you can hear the sweeping alarm-type sounds pushed to an FM radio via his voltage controlled oscillator circuit which has a range of about fifteen feet.
