ARDUINO BASED TV-B-GONE
Awhile ago, Ken Shirriff ported the TV-B-Gone to the Arduino. See the instructions here.
So I went ahead and took the output from the Arduino Duemilanove and amplified it with an n-channel MOSFET (D2601) to power 8 IR LEDs. I connected the LEDs in parallel (yes, I know that you aren't supposed to do that) using a power strip from a bread board and stuck that all in a cereal sample box. It works like a charm. I used a tall tact switch that was tall enough to be pressed through the cardboard.
This specific MOSFET is probably not the most ideal for this project, but it works. I just used this one because I had it around. It does use more power than normal and it does get warm while in use. If you were to go through the trouble to order a MOSFET for this project, I would get one that is a little more fit for this specific project.
If you plan on doing this, remember that you need a FRESH 9V BATTERY. If you do not, the Arduino will blink for a second and then turn off. If you plan on using more than 10 IR LEDs, you will probably need a more powerful power supply.
