I've always wanted to build a quadcopter, and I've got some free time so over the next couple months I'm going to try to build one from scratch. Sure, there are a lot of tutorials out there on how to build them, but many come with pre-packaged controls and are basically just buying the right parts and assembling them.
My main goal is to learn. I think quadcopters are a really exciting way to learn about Ardunio, Basic Circuits, Feedback Loops, Sensors, Soldering, Programming, and Flight. I don't need a helicopter that can lift a keg of beer, or one that can do crazy acrobatic stunts. I already have a nice low-cost quadcopter that has provided me hours of entertainment.
Basically i want to build a quadcopter that costs less than $100 and will fly indoors. It will be Arduino controlled. If it can do anything more, that'll be a bonus. In my $100 I'm going to include parts that are going to be attached to the quadcopter, but not tools I use along the way (including my inventor's kit used for prototyping.
I'm going to keep updating here with my steps... so I'll keep you posted!
