This tip was submitted by [Mike], with the original information seen in this post. When I passed the story along to our writer [Mike Szczys] I didn’t send along the entire email conversation. This bot is noteworthy because it has taught itself to walk. In the build log you can learn about how it has created its gait and altered it based off of the vision. There are also some great pictures of prototypes there too. While we can all agree that it isn’t as impressive looking initially as the A-Pod, remember that it wasn’t programmed to look impressive.

The Day After Arduino

February 10, 2010 by Caleb Kraft 60 Comments

There will come a day in every budding hacker’s life that they realize that plopping an entire arduino in their project and leaving it there is a bit of a waste. [Domiflichi] realized this, and has shared his next steps with us. He takes us through the process of removing the ATMega chip and breadboarding it for final use.

For many of you, this is an obvious chain of events. However, there are also many who just haven’t ventured forward and taken this one step that will forever change how their projects are seen by the hacking world. For the anti-arduino crowd, realize that this is an opportunity not to bash a useful tool but to help nurture and lead people to the next step.

CueCat, Meet Arduino

Have you ever felt like you needed a portable barcode scanner around the house? No? Well, [Mkanoap] did, so he made one. He has hooked his CueCat up to his Arduino to capture barcode data and store it on an SD card. He is using it as an inventory tool for his personal library. Where before he had to carry a laptop around to do his scanning, or lug the books to his desk, he now just scans wherever he pleases.

You may notice some silly sounds dubbed over the video. Take note, these are the actual sounds it plays. The camera didn’t pick them up well enough, so he dubbed them in. You wouldn’t want to miss out on the entire experience would you?

Porta Touch: Portable Multitouch

We just found this great portable multitouch rig called the portatouch. Made by a user at the NUI group website named [portatouch], this system uses a stripped down LCD as the display with IR LEDs edge lighting a touch surface in front of it. A camera mounted below the LCD picks up the reflections of the LEDs and converts it to touch points. While the implementation isn’t anything new, the package is really great. If you want to learn how to set up the technical side of it all, head over to the NUI group website and you’ll find all you want. We would love to see a more detailed breakdown of his rig though. The portability and quick construction are fantastic and seem like they could be reproduced without a ton of custom work.

ExoPC Shows Off Some Guts

February 7, 2010 by Caleb Kraft 10 Comments

The folks over at Engadget have posted some pictures of the ExoPC’s insides. With the recent return of the tablet craze (remember xp tablet edition?) we’re seeing tablets everywhere. This one has some promise on the hardware side, sporting a 1.6GHz processor and 2GB of RAM. Unfortunately we’ve heard using solely a tablet interface with windows7 is somewhat cumbersome even with the built in improvements. We’re not too worried though, a customized appliance style linux interface probably won’t be too far off.

The last couple times we mentioned tablet style computing, people have emailed us about the Touchbook. It also seems pretty cool, but seems like switching applications is visibly laggy in the demo video. Then again, a slimmed down interface might reduce some of that drag.

Pipe Heating With An ATMega8

February 5, 2010 by Caleb Kraft 22 Comments

[Viktor] wanted a system to keep his pipes from freezing. The common method of using heat tape works pretty well, but can be wasteful. Many people just turn it on for the entire winter. [Viktor] wanted to automate the heat tape’s power so that it only activated during times that the pipes could actually freeze. To do this, he rigged an ATMega8 to a temp probe and is using it to control an ATX power supply. Pretty slick [Viktor].

Icosatetrapedal Robot

24, Icosatetrapeds have 24 legs. This robot, built by [Monica Anderson] back in 2005 has 24 pneumatic soft legs. The motion is fantastic, like watching some kind of sea creature walk. Though it only goes about 1 meter per minute, we just couldn’t stop watching. The compressors were scavenged from some military equipment designed for nerve gas detection, and the brain is a mac mini. The rest is just valves, solenoids, wood, and tube.
