Discuss general guidelines for self-balancing robots

I'd like to start a discussion to collect general knowledge of what to do and what not to do when building a two-wheeled self-balancing robot (SBR for short).  My hope is that this thread can become a somewhat comprehensive set of guidelines to help beginners and non-beginners build their first balancing robot or  achieve a more stable and successful subsequent design.  Things that I would like to understand include:

Printing with trimmer line

As many of the shout box regulars have found out i have my printer up and running. when i finished it i had no material to print with and a massive desire to see my monstrosity work amd remembered something i had read online.People were experimenting with trimmer line (the stuff thats used in weed wackers/weed eaters etc...) but last i had looked into it deltas and bowdens were the new and most people were running 3mm filament. well after looking around i found .065 inch line which measures out to ~1.68mm.

Soldering tutorial

Hey there

When first starting out on electronics, I found soldering really frustrating, mainly because I was missing a few good tips and tricks that make it a breeze! So I've just finished off a video tutorial, and thought I'd post it here in case anyone finds it helpful :)

Arduino and a Chinese 32 channel servo controller

I bought a Chinese USC 32 channel servo controller on ebay a month ago. Last weekend I finally found some time to try it out. But I can not get it to work with my Arduino Mega, actually I thought there was something wrong with the board, unitl I downloaded the Chinese software for it, which lets you test the board. I connected 2 servos and the sliders in the program let the servos move. So the board works when using USB.
