To appease people waiting for the iPhone 3G unlock, iphone-dev team member [MuscleNerd] did a live video demo this afternoon. The video shows him removing the AT&T SIM and putting in a T-Mobile SIM. After the switch, the phone shows no connectivity. He then runs “yellosn0w” in an SSH session with the phone. The phone then unlocks without needing to be rebooted and the signal bars appear. The final test shows the phone receiving a call.

The target for this release is New Year’s Eve and it doesn’t support the most recent baseband. Well be attending the 25C3 talk hosted by [MuscleNerd] and other team members. The VNC screen you see in the video is thanks to [saurik]’s Veency.

Lately we’ve been focusing on multitouch technologies, but that doesn’t mean there isn’t interesting research going on in other areas of human-computer interaction. [Johnny Lee] posted a roundup of some the work that [Gonzalo Ramos] and others have done with pen based input. The video embedded above shows how pressure can be used to increase control precision. Have a look at his post to see how pen gestures can be used for seamless workspace sharing and how pen rolling can give additional control.

NanoTouch, Lucid Touchscreen Navigation

The fine folks at Mitsubishi Electric Research Labs (MERL) are demoing a new touchscreen system that may make small devices easier to use. An extension of their LucidTouch technology, NanoTouch has a small screen on the front and a touchpad on the back. Their test unit features a 2.4inch screen. The screen displays where the user’s finger is on the back touchpad as if the display was transparent. The user’s finger no longer obscures the screen surface, so it’s much easier to hit small buttons. In testing, researchers showed that targets just 1.8mm across were easy to hit. That’s much smaller than the iPhone’s touchscreen keyboard. Here’s a video demonstrating the new device.

Arduino Switch Box

When you’re prototyping a new project, sometimes all you need is a switch. The folks at oomlout were tired of constantly having to rewire things, so they built a universal switch box for the Arduino. It has five potentiometers plus three switches. They’ve put together a software package that monitors the switches and can show you a live view of the knob positions. Have a look at the video below for a demo.

The writeup actually hints at what we can only assume is the next kit they’re releasing: a robot arm. Continue reading “Arduino Switch Box” →

Wiimote Finger Tracking Music Controller

The Evolution Control Committee has been doing live mashup performances for many years and recently upgraded their hardware. Inspired by [Johnny Lee]’s Wiimote whiteboard, they built a rear projection display they could use during performances. It displays a dense collection of samples in Ableton Live. On each of the performer’s hands is an IR LED mounted to a thimble. By touching the thumb to the forefinger, the LED turns on. Two Wiimotes watch for these IR flashes to trigger mouse clicks. [TradeMark G] found the Ableton display too complex to navigate quickly and accurately with a mouse; this new display make things much easier and enjoyable.
