My PIC-based TV-B-Gone (design attached)

I built a TV-B-Gone based off Ada's design. She's given permission to share the design and construction details; she's even encouraged it.

I used a PIC. It's one of the newer XLP (eXtremely-Low-Power) chips they make and has more pins than the original AVR. How is it different? Well...

Code: Select all: PROS: * Has both start and stop buttons * More energy efficient Uses 80% less power in (deep) sleep mode Stop button saves running power CONS: * PIC footprint is larger * Less community support for PICs

Why: because I had access to a PIC programmer and I enjoyed making my own design. The addition of the (optional) stop button allows you to stop the sequence once you've successfully turned off the TV in question. This not only stop the blinking (optional) LED, but it saves power.

Looks good... But, I wouldn't want to get caught using one of those in Public! I had a buddy, back in the 90's. When the TV Remotes with the Auto Search for Code Function first came out. He brought one to a Restaurant that had TV's in it one time. It only took a few minutes for him to find the Code for the TV at the Bar. We were setting at a table close by... He had such fun changing the channels and turning the TV off... right when something interesting happened!:O People began looking around and wondering what the Heck was going on. We would have been heavily out numbered, if he would have been caught!:O Luckily for us. Not to many people even knew that this was possible, at the time!;)
