i found two basic circuits that allow a computer to be controlled via the serial port and a remote control. i am simply wondering if one circuit is bettter than the other. in other words, will one function differently than the other or give me some type of advantage? if you were to build one which would you do?

thanks.

 

They are very similar. One uses a Zener diode to regulate and one a 7805 IC.

 

Probably not relevant to the question but I have been looking at both of these for netbook mods.

Both are open source,both have diy kits and compatible software control.
