After many attempts at creating a robust and inexpensive H-Bridge I finally caved and bought this lovely high current motor controller.  I've heard good things about it.. but is it ready for the Red Beast !?!?!?

Probably the most expensive (non-computer) hardware I have ever purchased.

Its so amazing it comes in its own personal engraved case - wilth luxurious foam padding.  Well, it's time to pull it out of its case and start testing !

Open any Linux executable binary up in a text editor - and the little guys have written ELF at the beginning of EVERY FILE !!!  (They started the rumor that this means "Executable and Linking Format" .. but we know better !
