Nice use of a mint tin! – “This site features projects and circuits for building stereo microphones from low-cost Panasonic electret microphone capsules. Included are Mid-Side, XY, and Blumlein microphone setups. In addition, there are interesting related circuits and links to sites with microphone information and parts sources.” Link.
Brendan writes “I’m working on a little homegrown project centred around a creative use of a wireless webcam. Key to the project is the portability of the webcam. But there in lies the snag – power. I could go the iSight – laptop route which would work, and no need for power cables but ideally I’d love to have something that wasn’t as bulky. So anyway I was thinking would it be possible to wire up some hand crank power to a wireless webcam? Even if it only gave power for a half hour or so? Have you ever seen anything like this?” You could just wire up a 9v battery with a 5v voltage regulator (or whatever voltage the wireless web cam requires). Post your suggestions in the comments!
The Goldfish Online has some really interesting LEGO logic gates – “…designed working NOT, OR, NOR, AND, and NAND gates. Using two NAND gates I have produced a NAND gate latch or Flip-FLop. The natural follow on from these is clocked logic, full-adders and ultimately a genuine “computer” device. At the moment all these gates essentially just demonstrators. They work, but because of the limitations that arise through gear slippage, the real practicable use is probably not that great.” The details of logic gates can be found here – Link.
Fanjita writes “Following on from Tetris for GTA, I’ve put together a small package of source and useful tools for developing homebrew to run with the GTA loader. This package will allow you to replace tetris.bin with your own binary, and makes it easy to deal with some of the issues in the GTA environment. I’m hoping that developers (especially v2.6 owners) will use this package to develop simple homebrew to keep v2.6 users entertained while they wait for their firmware to be fully exploited.” Link.
Incredible engineering, math and robotics – “NASA’s Stardust sample return mission returned safely to Earth when the capsule carrying cometary and interstellar particles successfully touched down at 2:10 a.m. Pacific time (3:10 a.m. Mountain time) in the desert salt flats of the U.S. Air Force Utah Test and Training Range.” [via] Link.
RFID Toys looks excellent! And it’s written by MAKE pal Amal Graafstra – “The book contains step by step guides to building various RFID based projects, and stresses the concepts involved as well as the steps themselves. RFID technologies covered include passive, low frequency 125KHz tags and readers, passive high frequency 13.56MHz, up to active, UHF 900Mhz tags and readers.” Thanks Matt! Link.
Wow, what a week for new books, here’s another I’m looking forward to (also from the folks who publish MAKE) “Only a Game takes readers on a fascinating exploration of Massively Multiplayer Online Games (MMOGs) based on the experience of gamers and authors Mark Wallace and Peter Ludlow. When Ludlow’s online persona — an investigative journalist named Urizenus Sklar — began reporting in his virtual newspaper on underage cyber-prostitutes, real-life crimes, strong-arm tactics and scams that had become rife in the popular MMOG “The Sims Online”, the game’s creators (Electronic Arts and Maxis Software) found an excuse to ban Ludlow from the game.” Link.
