DIY scratch controller

There’s something viscerally pleasing about simple solutions. [Kip] came up with one in the form of a scratch controller. The spindle from an optical drive is used to hold a CD in place, which acts as the LP for scratching. The sensor from an optical mouse is mounted upside down below the CD and detects the rotation of the disc. From there it’s just a matter of setting up your software to get the reading from that mouse. He’s had some trouble finding disc surfaces that the mouse sensor will read reliably.  We’d recommend trying some of those stick-on inkjet CD labels.

This is similar to a scratch controller we saw in 2008. That one was actually repurposing the IR encoding from inside of a mouse. We’re not sure which method would work better, but either controller will make a nice addition to a Flexi Knob setup.

Update: Nintendo DS camera control

All of the juicy details needed to control a camera from your Nintendo DS are now available at the Open Camera Control project. This is the descendant of [Steve Chapman's] setup from a few years ago. The system has been polished up and has seen many feature additions. It’s been used in movie production and works with a wide range of cameras.

Start by building your own interface cable using an AVR microcontroller running the Arduino bootloader. Finish up by loading some open source software onto the DS to add a cornucopia of shot options.

Hardware jailbreak eases reboot pains

This device can jailbreak an iPhone. It doesn’t require a computer and it can either reboot a phone that was one-time-boot jailbroken using the blackra1n exploit, or jailbreak a factory fresh unit. We wouldn’t say this solves the tethering problem caused by blackra1n (needing to return to a computer to reboot the phone), but it certainly does ease the pain. We saw some info about the board layout but no parts list or firmware. See the demo after the break and leave a comment if you have more information on the parts or code.
