Cheap wireless for microcontrollers

hr_RF_circuit

Everybody loves microcontrollers, including the Arduino, allowing you to create whatever you imagine. That is unless you want to hack together something wireless. Originally you had to rely on the expensive XBee protocol or other wireless options, but no longer. Hobby Robotics found an extremely cheap transmitter and receiver and wrote a quick guide for wiring them up to an Arduino. Now your wireless projects can come to life, as long as you are within 500 feet and don’t mind 2400bps; minor trade offs compared to the gains of wireless freedom. Final note: You aren’t limited to Arduino, we would love to see someone modify this to work with a PIC or other microcontroller.

The Linux4nano project has been working to port the Linux kernel onto the iPod Nano along with other iPods in general. Although the iPodLinux project has had luck with some older iPods, newer models protect firmware updates with encryption. One of the ways they plan on running code on the device is through a vulnerability in the notes program; it causes the processor to jump to a specific instruction and execute arbitrary code. To take advantage of this, they first need to figure out where their injected code ends up in the memory. Currently, they are testing every memory location by painstakingly loading in a bogus note and recording its effect. Each note takes about a minute to test and they have tens of thousands of addresses to check over several devices.

Your music in Rock Band 2

[Peter Kirn] over at Create Digital Music takes an in depth look at the process of adding your own music to Rock Band 2. This involves using REAPER audio production software, uploading your work via the XNA Creators’ Club, and then playing the fresh track on an Xbox 360. Both REAPER and the XNA Club cost money, and the total price comes out somewhere between $100-$160. The process is now in closed beta but a wider beta is expected in September followed by a full release in October.
