Jo0ngle is showing the cheapest way of making your own laser show with good results. Most of the materials probably are laying around your haouse or garage so why not make one right now? The result are much better than some more expensive ones and none will believe you when you tell them the cost. Feeding it from a function generator may give better patterns but i dont think it get worse with music.
camerons started out with the goal of building a standard mp3 player with a remote as a class project for Stanford's EE47.
He didn't only made it but he managed to do it with a tricky way to. The result is a player with full remote capabilities and in a neat case also. And remeber, don't get fooled by the apple. ;)
Code, details, more videos and complete documentation you can find here.
Yifeng Huang describes his project as "a handheld personal music performance device. You can upload songs, then use the built-in accelerometer to change the play speed, scratch, and more".
Apart from these functions allready implemented in the device the maker plans some more such as, song announcement, automatic download software and reverse play support.
To watch the full details and progress of the project along with schematics and code check here.
Alain V. made a simple project with an RFID reader attached to an arduino microcontroller which sends the commands to a pc and enables him by selecting different cards or tokens to start play a playlist or stop it. Nice, simple and does the job with a hi-tech touch. You can find all the info you need here.
Geoffroy Tremblay built a prototype of an audio mixer with and Arduino Board ~ connecting to processing, on a machine running puredyne os. The fact that arduino sends serial signals over USB which isnít understood by audio software emerged the need for a midi usb device, this device came on a kit to end needede electronics. The project needs a box but except this is fully operational. The whole story can be found here.
THEtechknight builded a transmitter that broadcasts on FM band from parts found here and there. The result is a very sharp tuning transmitter working like charm. You can watch the other 2 videos explaining the construction here.
truebassB demonstrates his DIY audio crossover, simply made with a 8.2uf Capacitor for the Tweeter and a 0.39mH Inductor for the Low Cut so the Crossover point will be about at 3200hz. The result is good even on YouTube sound, nice simple and it works. More pics can be found here.
yofranchino found a crazy way of change his auduino synth manipulation, he let ants do it! Having some IR gates in the paths ants created on his antfarm the ant community movement is responisible for sound change. Lets hope ants dont ask for copyrights. :)
Guys at EasternVoltageResearch made a tesla coil kit that was specifically designed to reproduce high quality audio through plasma modulation. In otherwords, the high voltage arcs from the Tesla coil are modulated so that they create audio sou...
