The Harlequin Project

December 11, 2009 by Caleb Kraft 15 Comments

This impressive little mod is quite fantastic really. [pakkei] has constructed the Harlequin, a home-made version of the Microsoft courier. This was a stock Dell mini9. Now, coupled with a display link touch screen monitor that happens to be identical in size and resolution to the original, it has become a new device. He has loaded Windows7 and is currently working on a case that can hold all the bits a little more organized than what you see above. We can’t wait to see this finished.

Creating Wooden Enclosures

December 8, 2009 by Mike Szczys 19 Comments

[Matthias] built a wooden enclosure for his keyboard. He’s used to using a Commodore 64 keyboard and decided he didn’t need the num pad found on modern keyboards.

It’s not the finished product that interests us, but the methods he used to create such a nice looking enclosure. From the wooden binary adder he produced we know he’s a talented woodworker. He takes us step-by-step through the use of a scroll saw, table saw, and router tabled to turn out this one-of-a-kind. You may not own these tools but someone you know does. Follow his example and turn out your own wooden wonders.

[Thanks Harald]

Pranav Mistry’s Cool Input Devices

This new video about [Pranav Mistry’s] SixthSense project doesn’t bring us much that we haven’t seen before. At least, not on that project. What really caught our eye was the device he shows off at the beginning of the video. Using two old ball mice, he constructed a grip style input device. It is simple and elegant and we can definitely see using this in future hacks. Not only is it cheap and apparently effective, it seems as though it could be constructed in a very short amount of time. all you need are the wheels that spin when the ball moves, 4 springs and some string. Why didn’t we think of that?

Tiny Keyboard/touchpad Has “hack” Written All Over It

November 26, 2009 by Phil Burgess 27 Comments

Yes, we know, this is not a hack, yet it just has the vibe of something we’ll likely be seeing in many small form-factor systems and wearable hacks in the future.

The USB Wireless Handheld Keyboard is a diminutive keyboard and mouse replacement with a passing resemblance to a BlackBerry PDA — where the screen has been replaced with a laptop-style trackpad sensor. This seems a shoo-in for home theater PC use; it’s unobtrusive and won’t look out of place on the coffee table alongside the universal remote. But any tiny system requiring only occasional input could likely benefit.

The keyboard layout is funky as heck, though likely adequate for its intended use of couch web-surfing and interactive messaging (or whatever wild applications our readers will surely come up with). A USB wireless receiver and a charging cable are included in the $62 package. Video after the break…

USB Accelerometer Controller

As you can see above, there is no wiimote in that accessory steering wheel. There is, instead, a home-made accelerometer controller that connects to the pc via USB. Based around a PIC 18F2550 and a 2 axis accelerometer, this device is detected by windows as a standard controller. The schematic and source code are available on his website. He says it can also be used as a “motion mouse”. You can see a video of that after the break.

When we first saw the video, we thought it might be the same person as the accelerometer controlled maze project, due to the wiimote steering wheel casing.

Server Not As Think As You Drunk It Is

November 3, 2009 by Mike Szczys 11 Comments

server-in-whiskey-bottle

[Janos] pulled off a unique case mod by fitting a computer system inside of a whiskey bottle. Inside you’ll find a 733MHz processor, 256MB of ram, a 40GB hard drive, and a 60 watt power supply. The specs seem a little light but since this mod is from 2006 we certainly understand. Using the right server software this will still keep up with today’s demands.

It sounds like the hardest part was putting holes in the bottle. After a few failed attempts, [Janos] found a professional glass grinder to cut the openings for him.

The whole thing was running a little hot and instead of filling the bottle with oil (oh, how we wish he had) he added a second fan in the bottle’s neck and drilled some air intake holes. This brought the temperature under control while preserving the boozy look of this creative enclosure.

Computer Learns From Tic-tac-toe

November 2, 2009 by Mike Szczys 30 Comments

menace-tic-tac-toe-computer

MENACE, the Matchbox Educable Noughts And Crosses Engine, is a fancy name for a machine that plays Tic-Tac-Toe. The concept is a product of Professor [Donald Mitchie]’s work in the 1960’s and was featured as an example in the “A New THEORY of AWESOMENESS and MIRACLES” talk given at this year’s UK games conference.

[James Bridle] built this fascinating example of how a computational system can learn from its successes and failures. Each box corresponds to one of 304 different board layouts. The operator uses an index sheet to locate the box that corresponds to the current state, shakes the box, then looks to see which bean has randomly fallen into a partition in the box. The color/type of bean corresponds to a space that the machine has “chosen” for that move. If MENACE won the game a bead matching the move that was played would be added to each box used. If MENACE lost, a bead would be removed from each box used. This way the machine cannot make the exact same mistakes twice, and is more likely to repeat successful solutions.

[James] notes that he couldn’t find any evidence of this machine actually being built before. It is possible that this was always a theoretical device but now we’ve seen an actual build. We consider this to be a computer because it is calculating moves based on probability of success but what do you think? If you’re thirsting for more pictures there’s plenty to see in the Flickr set he’s posted.
