Arduino music.
Notice: this article is for linux based users. see also: http://computoman.blogspot.com/2015/05/arduino-music-starter-update.html The Arduino is one of the neatest microcontrollers. For something so simple, it can do an amazing amount of projects. One such project that interested me was the Digital melody project. If you have one the the Arduinos where the Atmel chip can be removed, you can make your own project without the board once the programming is done. For this project, all you will need is the Arduino, usb cable (for programming), computer, some wires, optional 100 ohm resistor, and an old eight ohm speaker. Usually the back of speakers on the magnet have what resistance they are. So grab the old dead radio or the like that has a speaker and see what it has. Old personal computers are likely to have one too that you can borrow for a minute. Now you need to build the circuit. It is minimal and you should be able to set it up quickly. Resistor adds safety for pr...

Cutting cable the cord - additional options.
If you were lucky enough to get the free coupons for the free dtv converters, you could still use your analog TV for watching television. In fact, we use the dtv converter with a dvd player in the man-cave. ( http://www.instructables.com/id/Extra-TV-setup/ ) We get about sixty stations, but only use about twenty of them. You will get the traditional major TV networks for free. Ironically, more and more cable is coming back to over the air TV in one form or another. See your favorite Food TV chefs on "The Chew". Also cut the cord, but we went in a different direction. We use OTA (Over-the-air) HDTV. (Works best in large metropolitan areas). Actually, most television stations still transmit the old fashion way. You can not use the old fashion tv tuner, but again you can use the dtv converter with an old fashion TV antenna. You do not need to use a special HDTV antenna. Marketing hype for an existing TV antenna. You can also make your own for almost free. You can find s...
