Kevin Core has created a Batmobile Case Mod using an AMD Sempron 2800+ and 1/6 scale Batmobile R/C that he bought at Wal-Mart.
There are a total of 7 HD activity LEDs on the Batmobile PC – (3) red in the jet exhaust, (2) blue-1 on each side and (2) red in front. This was accomplished using an opto-isolator.
