Android Skips Uncanny Valley – Fills In At The Office For You

March 9, 2011 by Mike Szczys 51 Comments

For those that are unaware, Androids are often judged by where they fall on the uncanny valley curve, a graph that maps human revulsion to robots that closely resemble humans but are just a bit off (similar to how a corpse resembles a living person). This offering jumps right over that dip of the curve and takes its rightful place as a human stand-in. Well, except that you’re probably going to notice the limbless torso… but pay no attention to the man behind the curtain!

This is the result of research by Geminoid Lab at Aalborg University. It is the twin of its creator and in an effort to be as human as possible, movements are mimicked using facial recognition from a human operator. We’d bet that with some clever learning routines you can map out and index common mannerisms from the original person for later use with this body-snatcher-esque copy. Take a look at the clips after the break; we don’t think you’ll be creeped out at all.

Soda Bottle Skylights

March 8, 2011 by Mike Szczys 57 Comments

Here’s a way to brighten up enclosed spaces in an environmentally friendly way. The power of the sun is harnessed using a bottle full of water. Quite simply they’re used 2-liter soda bottles. They’ve been filled with water along with two caps worth of bleach to keep microorganisms out. The cap is then covered with a film canister to protect it from the sun. They are installed through holes in the roof, and in full sun they put out the equivalent of a 50 watt incandescent light bulb.

Our first thought is keeping the weather out but that is addressed in the video after the break. With proper weather sealing they do not leak. We might not be installing them in the house just yet, but what a great addition to that dark shed that has no electricity and seems to gobble up yard implements. Perhaps we’ll finally be able to find all of those hand trowels that have gone missing.

On-the-go Desktop

March 8, 2011 by Mike Szczys 22 Comments

Here’s a desktop you can take with you. [Rbean] built it at a hackerspace in Milwaukee, Wisconsin (go Badgers!) using very basic materials and techniques. The utilitarian construction of the wooden body reminds us of Cub Scout tool box projects. It features an open space in the top which house the keyboard and mouse during travel. The blue strap lets you sling all forty pounds over one shoulder, but we’d also love to see a thick dowel to go along with the toolbox concept we’ve got stuck in our mind.

The lower half of the case is removable, serving as the mounting area for what looks like a mini ITX motherboard, hard drive, and full-sized power supply. As you can see the LCD screen mounts to the side of the box which allows you to rest the unit on its side and protects the display if the whole thing were to be knocked over. [Rbean] mentions that he’d like to try another revision using aluminum instead of wood, but we like this version. The only thing we’d want to see added is a set of speakers mounted inside the case on either side of the monitor.

Controlling Fire With Your Mind (and Your Thumb)

March 8, 2011 by Mike Szczys 6 Comments

[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.

CAN Sniffing For Steering Wheel Button Presses

March 8, 2011 by Mike Szczys 32 Comments

You can make those buttons on your steering wheel much more functional if you have a way of monitoring them. Don’t even think of cracking open the factory finish to get to the solder points, just tap into the CAN bus and monitor the data traffic.

The small board seen above is the result of a project [Peter Shabino] calls the CAN sniffer. The connector on the left will plug into the Control Area Network system on your car, giving the chips on board something to do. There’s an MCP2551 CAN transceiver (hidden under that linear regulator) and an SPI controlled MCP2515 CAN controller which take care of the particulars of the CAN protocol. The big chip in the middle is a PIC 16F876, responsible for making sense out of the data. From there a MAX232 chip is used to provide a serial interface to connect the device to a computer.

This really isn’t tied down to one particular function. Once you have access to the bus for a microcontroller you’ll only be limited by your firmware writing skills. [Peter] has posted an archive with all of the open source files, as well as an illustrated step-by-step board assembly. We’ve embedded the schematic from that archive after the break.

Literally Turn Your Headset Into A Handset

March 7, 2011 by Mike Szczys 17 Comments

[Rachel’s] Bluetooth glove is proving that you don’t have to be missing fingers to talk to the hand. You can see in the video after the break that, like us, she wears fingerless gloves while typing to keep the cold from causing pain in her hands (it’s so cold in here it’s like we’re [Bob Cratchit]). So why not make those gloves multitaskers?

She cracked open a small Bluetooth headset to see if it would play nicely with her fuzzy purple gloves. A bit of wire and some shrink tubing allowed for the speaker and microphone to be moved a bit further from the circuit board. Once those components had been extended she pinned everything in place to make sure it fit the bill. The components were then sewn in place and a microswitch for answering calls was repositioned in the hollow of the wearer’s palm. Now you’re free to work the day away, with all of your incoming calls already at your fingertips.

14.4 Kbps Modem Makes Excuses For Everything

March 7, 2011 by Mike Szczys 14 Comments

If your boss is like [Michael Scott] you probably find yourself in constant need of plausible reasons for your action or inaction. Now you won’t have to waste away the workday coming up with those ideas yourself because this little box will always provide you with an excuse. It’s actually a 14.4 Kbps modem, which brings back memories of the early ISP days when you’ve find banks of these in the corner to service incoming calls. [Alex] altered the circuit board to map out an ICSP port for the PIC 16F690 that controls the system. Just use your key to unlock the Emergency Excuse Generator and press the button to spit out a doozy. The 8,000 word memory on the microprocessor stores all of the excuses which can be combined a number of different ways based on how the rules files is built. This rule file is by far the most interesting part of the build and worth looking over.

We think this would be a nice addition to the other office electronics you built.
