Today I was working on a model using whegs, inspired by the thread about it. Great, you say.

Good for you... (Weird kid)
When, out of the blue, RCX stops working. It had been working just fine earlier today. It's not the batteries, although they had been low. It now refuses to even blink the LCD screen briefly, even with new batteries.
Anyone had this happen before? Is there a way to fix it? Have to ask; I don't want to spend $120 or $200 for a new one...
