Everyone’s favorite packet sniffer has a new stable release. Wireshark 1.2.0 has a slew of new features. They’ve included a 64-bit Windows installer and improved their OSX support. A number of new protocols are recognized and filter selection autocompletes. One of the more interesting additions is the combined GeoIP and OpenStreetMap lookups. We’re excited about this new release as Wireshark has proven an indispensable tool in the past for figure out exactly what was going on on our network.
Create Digital Music has a great post on [Luca De Rosso]’s OTTO. Built as part of his masters’ thesis, it’s a unique tangible music interface. You load a sample into the software which displays it on the instrument surface. The user can then manipulate the sample using various hardware inputs while watching the LED representation. The device uses just one Arduino for the display and inputs. It works with Max/MSP and is designed to give the performer only the information they truly need. You can find more pictures of the device on Flickr and a picture of the guts on CDM. Embedded below is the ‘Getting Started’ video that shows it in use.

[Humberto] from NerdKits sends in the newest addition to their excellent collection of videos. This video goes over the basics of DC motor control with microcontrollers. They begin by showing nine experiments and observations that can be done by the average hacker with a multimeter, motor, LED, and jumperwire. Using the results from these they show how to model and calculate the properties of a motor. Lastly, it shows how to control a motor using PWM. They have supplemental text and demonstration code for an ATmega168 on their website.
Macetech’s ShiftBrite is a high-power RGB LED coupled with an Allegro A6281 backpack. The A6281 uses three 10bit pulse-width modulators to mix millions of colors using the red, green, and blue elements in the RGB LED. Multiple modules can be chained together for bigger projects, like the ShiftBrite table.
Below the break we demonstrate a ShiftBrite module using the Bus Pirate. For a limited time you can get your own Bus Pirate, fully assembled and shipped worldwide, for only $30.

[Hunter, Kyle, and Dylan] sent us some information on their Barbie Web Rover. It’s an old barbie power wheels jeep that’s been converted to a web enabled remote control car. They ripped out the old drive train and tore out the steering system. The rear tires are now independently driven for steering. It’s using an Arduino to control the motors and an Acer Aspire loaded with linux for the higher functions. It’s cool that they mention the farthest test being over 1600 miles away, but when it’s web enabled, does distance really matter?
They mention that the coolness factor is proportionate to the size and we have to agree, as long as they keep it small enough to not cause any real damage. You can build a web enabled rover with a little more effort from just a router, if you don’t want to give up your laptop.
yes, drums are tangible. We know. What this is, however, is a tangible interface that is a drum machine. The software is freely available for download, after registration. For hardware, all you need is a webcam, a computer, and a way to print out the pieces. D-Touch is cross platform which is very nice. Please note that the software will not run until you activate it by putting in your user account from their site. If you like this project, you might also get a kick out of the Go Sequencer.
