Best way to remove hot glue?

It's hapenned and I'm sure it must have happened to you - some time or another.I was just finished hot gluing my 2 servos and front ping sensor- just to find i've glued them the wrong way.(Pulling hairs out of my head right now).Now my acrylic chassis is full of that white,glossy,gluely stuff i'm trying to rip off with my nails(And its not a fast way - also prone to leaving scratches on acrylic).I want it all removed- sans any marks on the acrylic.Is there a easy, fast or effective way?

Complete Newbie - College Project - audio question

Hello all,

I am completely new to robots and it seems like it's gonna be a lot of fun.  I am in a college class right now with a project of designing a robot.  Here is what I know:  We are using parallax microcontroller (I think... Board of Education Rev C), and I have gotten familar with the basic terminollogy.  My team plans on making a simple bot like the start here version, except bigger, with tracks, a nice cover, and some lights.  However, we really want to incorporate some audio clips and music...

Pololu RP5 motor

Hi there, I have recently bought a RP5 chassis from pololu, this chassis is holding 2 brushed DC motors (6V) and I have some questions: first of all; how can I control it? I mean, do i need to control it by PWM or is just 5v or 0v?

second, I built a little pcb with a L293D to protect the controller (Arduino) from reverse current, is this ok?
