ascii :: the roots of ansi/ascii art

acid underword bbs circa 2018

i've been a long time fan of text mode art. i got my first glimpse into that world back in the nineteen hundred and nineties, with groups like ACiD and remorse. back in pre-modern internet days we had to dial up a BBS (bulletin board system) to chat or download files. over time, these systems became either mail/chat hubs or w4r3z distros. because of the questionable legality of some of these releases a login system was added to all BBS' (though many supported a "guest" login"). some had open registration while others were invite only.

LSDj keyboard tutorial

h4x :: DIY gameboy piano interface

LSDj keyboard

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.

games :: the nintendo DS homebrew revolution

R4-DS the 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.

h4x :: console modification for better sound recording

nintendo gameboy prosound mod

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.

h4x :: DIY portable RF jammer

NYC cityscape

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...
