The Elevator Music Box

The Elevator Music Box

ElevatorGreat (old) project from Rocketboom’s Andrew – “This project was designed to create an isolated box which can be placed inside of an elevator to play dramatic sound designs based on the direction and altitude of an elevator. A microprocessor chip is stamped with conditionals to determine the location of the elevator based on barometric pressure and then pulses are sent to trigger an mp3 player which, when amplified, plays out from a complex set of musical relationships to create a dramatic and playful experience for the unassuming passengers.” Link.

Laser beam detection with a serial port…

BeamGreat how to on detecting a laser pointer “break” using a serial port – Chard writes “Ever wanted to make your own laser beam security system. You know the kind they have in the movies, with dozens of lasers and the thief has to limbo through them. Well, I just made a simple laser beam break detector. My computer can now tell when the beam is broken. The parts I used are: 5.6k resistor, photo diode, Digikey part #PDB-V107-ND, serial port from my PC…” Link.

HOW TO – recreate trips with Google Earth, and a GPS

HOW TO – recreate trips with Google Earth, and a GPS

75956812 8633E0207CCMPalmer writes “This may be old hat to most, but I’ve posted an example of using GPS tracklogs and Google Earth to virtually recreate vacation trips. I uploaded the GPS tracks into Google Earth so I could visualize them. One of the coolest tricks that Google Earth does is to let you “fly” along the tracks at any speed and altitude that you wish, so I can virtually recreate each drive over 3D scenery overlayed with satellite photos. This would have been great to do real time while I was there, because I was extremely frustrated to find that I had missed wonderful things that I drove right by or were just a few blocks away from.” Link.

Apple and Makers modding minis…

AppleminiOne of my predictions for 2006 was going to be that Apple embraces the Mac mini modder community in an interesting way, and now they crossed that one off my list before the new year! – check out their new section showcasing many of the cool mini projects (we’ve featured some of these on MAKE, but it’s awesome to see them on Apple). “Mac mini packs so much power and versatility into its tiny case that it’s no wonder people all over the world are finding fun new ways to use it. Here we highlight some of our favorites.” Link.

Schrier writes – “It can correctly calculate the dates of Hannukah for at least the next few thousand years (or any historical date back to 2 B.C.E.). As well as “lighting” the candles based on when the sunsets (I set the default geography for San Francisco/Berkeley, but you can enter any latitude/longitude and (assuming you don’t live too close to the arctic circle) it will be correct to within a few minutes. Furthermore, the shamas (candle you use to light the other candles) can blink out any morse-code message you want It will convert the words to morse code for you!” Link.
