arduinoArticle featuring on instructables.com.

A qucik instructable on how to construct a Arduino based TV annoyer, which would turn on TV when you want to turn it on. To quote the original article:

Hey Arduino fans! Here is an ‘ible for making a device that turns TVs on when you want them off, and off then you want them on! If you hide it in something inconspicuous, it would make a great April Fools joke or gag gift.

 

Required components:

  • 1x Infrared Detector ($0.78) http://goo.gl/6sSN6
  • 1x Wide angle Infrared LED ($0.23) http://goo.gl/5PFlS
  • 1x Narrow angle Infrared LED ($0.23) http://goo.gl/67sCf
  • 1x 2N3904 PNP transistor (or equivalent) ($0.08) http://goo.gl/XD3jI
  • 1x 10 Ohm resistor (Brown, Black, Black, Gold) ($0.05) http://goo.gl/UiKDs
  • 1x 47 Ohm resistor (Yellow, Purple, Black, Gold) ($0.10) http://goo.gl/89jXQ
  • 1x Arduino Uno (or equivalent) ($25.00) http://goo.gl/p9wVs
  • Some wire (preferably solid-core, 22 gauge or so) (About $7-$8 at your local hardware/electronics store)

Required tools:

  • 1x USB A-B cable (for programming the Arduino) ($2.95) http://goo.gl/3f6rx
  • 1x Soldering Iron (Optional) (About $15-$25 at your local hardware/electronics store)
  • 1x Spool of thin solder (About $10 at your local hardware/electronics store)
  • 1x Solderless breadboard (About $5-$6 at your local electronics store)
  • 1x Computer (I would hope you know where to get one of these)
  • 1x Arduino IDE (can be downloaded here)
