LSDj keyboard tutorial
lab :: DIY gameboy piano interface
so, making music for LSDj is fun. but after a while you start to wish you could “play" the gameboy software as a musical instrument as opposed to composing music in its tracker style interface. that's where the LSDj keyboard comes in. the idea is, the keyboard sends messages though the gameboy linkport to LSDj. the commands that can be sent vary from playing/stopping notes or chains or tables, un/muting channels, in/decreasing octaves, switching instruments, navigating screens, and more.
here's what the LSDj wiki says about the keyboard...

entertainment :: the nintendo DS homebrew revolution
the nintendo ds is an awesome portable gaming system. i have the ds lite, its thin, weights under a pound, has two super bright backlit screens, pretty sweet integrated speakers, the classic nintendo plus d-pad, four front buttons, and two shoulder buttons. the bottom screen is touch sensitive, which makes for some awesome gameplay. the touch screen is sick, but a lot of people can be put off by it. so tons of games let your switch between the touch motion and d-pad motion.

gameboy prosound mod
lab :: console modification for better sound recording
today’s mod is for the original nintendo gameboy. if you want to get serious about chip tunes, whether your using lsdj or nanoloop, the sound quality of your instrument is a priority. the stock nintendo gameboy is equipped with a single headphone jack. and if you have ever tried recording anything from that, it sounds pretty bad. thus the prosound modification was invented to add a line out jack to the gameboy.

lab :: DIY portable RF jammer
i just got clued in on a new project from one of the members of the cDc (cult of the dead cow), a notorious hacker group from way back in the l0pht days. the wave bubble is a self-tuning, wide-bandwidth portable RF jammer. an internal lithium-ion battery provides up to 2 hours of jamming (two bands, such as cell) or 4 hours (single band, such as cordless phone, GPS, WiFi, bluetooth, etc). the battery is rechargeable via a mini-USB connector or 4mm DC jack (a common size). alternately, 3 AAA batteries may also be used. self-tuning is provided via dual PLL, therefore, no spectrum analyzer is necessary to build this jammer and a single wave bubble can jam many different frequency bands...

dont take the "blue pill"
lab :: new rootkit exploit
so i bet you haven’t heard about "the blue pill" exploit yet... so here's the basics. circa 2005, amd and intel started adding virtual machine functionality to the instruction set of the processors. the idea was having a virtual machine running natively on the processor, not an emulated one, which would cause an increase in speed. the virtual processor then switches to what's called “ring1 mode” which is like a basic user with limited privileges. In this mode, it can't touch any of the memory of the standard os, which is running in “ring0 mode”. this switch only happens when weird instructions go in that need to take advantage of the full cpu.

the magic number
entertainment :: HD DVD processing key leaked

everyone is going crazy over this. in case you’re a n00b and don’t know, this is the 'processing key' for all HD-DVDs out currently. this means that linux will now have the ability to decode and play HD movies, as well as facilitate the creation of HD-DVD backup warez. this number cannot be copywritten, so feel free to share!
lab :: my first DIY pc
today was a little too interesting not to write about. I woke up and checked to see if the paint was dry on my new computer. I made 3 camouflage stencils that I used on the entire box (including cd/dvd drives, sound blaster audigy, power buttons, EVERYTHING!). I also cut out a toxic symbol as the case window on the door. after putting all the components in, and a brief battle with some jumper settings, it finally turned on and recognized all the devices.
