How about using the BotBall Handyboard instead? It has PWM outputs, plus the advantage of many more inputs/outputs. It can drive any of the lego motors / sensors. My guess is you won't need any kind of signal amplification. I'm not sure you will be able to drive a speed controller with the Mindstorms motor outputs.

: A local school is having fun with their lego league team here in Kokomo... but they want to drum up more interest and support.

: They have made various cool robots from the Mindstorms kit, and they've done alot of presentations, trying to get more students involved. Whenever they present one of their creations, they are having a hard time getting people to take them seriously and look at the robots for more than just toys.

: So, the team wants to be a little dramatic and really show the crowd something drastic during a presentation. They want to run their Lego Mindstorms robot, stop it, manually remove the RCX controller, insert the RCX controller into a big robot (a FIRST robot), and then have the big robot operate just like the Lego robot.

: The Lego team would like to do this... but we're not sure how. I would imagine that we would need some amplification of the signals from the RCX, and somehow link it to the Innovation FIRST controller. We have not investigated anything yet. Has anyone else done this? If so, do you have any suggestions?

: TIA,
