So the next thing could be an Chip-8 emulator runinng on a medium sized Atmega. CHIP-8 is an interpreted programming language, developed by the late Joseph Weisbecker. It was initially used on the COSMAC VIP and Telmac 1800 8-bit microcomputers in the mid-1970s. CHIP-8 programs are run on a CHIP-8 virtual machine. It was made [...]

Wrote a quick & dirty python wrapper for the bluez-utils bccmd command to set a the btaddr of an bluetooth hci device. The native bccmd syntax is awkward, so that i found it handy to have a script which accepts normal formated btaddr as an argument and does some error checking and status infomation. Usage: [...]
Since the 23c3 every interested researcher knew that is easy to compromise bluetooth sessions using the BTcrack tool.Thierry Zoller showed how it’s possible to retrieve link keys, The only problem was to get hands on a bluetooth sniffer device to get the raw bluetooth packets. Such devices are not available at consumer prices. But somehow [...]
A new Kbtsco release is available. Did some small tweaks. Added Channel Forcing via Configure Menu. Some people reported having problems with the channel auto dedection, so that it’s now possible to asign the channel manually. Added Cancel Menu item to interrupt the connect process, in case somebody hits the Connect button when no headset [...]
The Alsa-Bluetooth project project provides a way to use a bluetooth headset with Linux.They do this currently by making an alsa kernel driver which uses bluez to reach the headset. I Wrote a KDE based user space daemon wich works as drop in replacement for the btsco daemon from the Alsa-Bluetooth package. The Programm is [...]
I wrote an extension to the BlueMp3 firmware. Now you can use an loudness filter on the mp3-player. After reading the VS1001 specs, the BlueMp3 mp3-decoder, i noticed that it’s possbile to upload code to the dsp.This code can manipulate the current mp3 stream, so perfect for a loundness filter. I worked through the VS1001 [...]
After reading the CT article about the BlueMp3 player, i knew i need this piece of hardware. It’s an bluetooth mp3 player based on the Atmel Mega128 cpu. The firmware source is available and the client is linux based. So what do i need more to play around? I ordered the pcb and parts at [...]
