What am I doing wrong with this wiring?

I am playing with an animatronic toy I got from a thrift shop. Before I started trying to hack it, there was a rocker switch that when pressed in one direction, made the head turn left, and when pressed in the other direction, made the head turn right. I have hooked this up to my arduino by replacing the switch with transistors, but the head now will only turn right. Without knowing exactly how the circuit board inside the toy works, is there enough information to figure out what I'm doing wrong? [more inside]

Arduino & other electronic project kits for a 10 year old boy

More gift advice needed! For a 10-year-old science geek with advanced computer and electronics skills for his age, I am looking for cool electronics project kits. He has an Arduino starter kit and has worked with that a lot. He has some soldering skills. He's into digital audio at the moment. He also has a Mac laptop and an iPad, in case it's relevant. Looking for things in the $75-150 range.

No seriously, a large print Arduino would be great...

Back in the days of yore, my (almost) 77 year old father was quite the geek and maker, but never a programmer. Fast- forward to today and he can no longer work on big building projects and spends much of his time with his iPad and TV. We've been discussing what kinds of "doing" projects he'd like to work on, but the obvious contender of an Arduino is maybe a little difficult as I'm not in Australia to help him out with the programming side of things. What great projects have you known senior geeks to get into? [more inside]

What kind of gadget can a newbie build using the vast inventory of Akihabara?

I need an easy, yet cool-looking electronics project. In around one month, I'll be visiting Tokyo, including a day-long trip to Akihabara. Inspired by this post I think it would be really, really cool if I spent part of that day buying parts in order to create something electronic. Difficulty: I have close to zero experience with electronics. [more inside]
