Drone #11: It's been a while

Dammit! It's been such a long time since I've worked on the drone! :( I've once again taken on too many projects. I will finish this drone I just need to somehow make more time. (See next post :))…

Drone #10: Closer to liftoff

It's been a while since I got any work done on the drone. But this weekend has been good (except for the terror attacks in Copenhagen obviously - fortunately, the police shot the suspect. Hope they got the right guy). Anyway, last weekend I added female Deans connectors to the…

Drone #9: The first parts

So it took a while, but now all parts have arrived (except some bullet connectors that the postal service PostDanmark apparently decided to give to somebody else - I'm pretty happy that it was only 40 DKK worth of connectors and not my 5.5K DSLR I got a week…

Drone #8: Flying experience

I bought a Hubsan X4 just to learn to control a quadcopter before trying out my own. This is what I learned: 1: Difficult to calibrate The controller was difficult to program. Almost no feedback shown if what you did to calibrate was correct or not. With my quadcopter I'll…

Drone #7: Examining components

I took a look at the components I just received yesterday and realized a couple of things. Here's a picture of the complete power system with the components of one "wing": Power system To the left we have the battery which supplies power to the ESC (Engine Speed…

Drone #5: Shopping list

And here's the shopping list (a few parts have been changed since I took that picture though). In the coming days I will order the parts and tools and in the mean time try to figure out how to make the frame. Update [later]: Just ordered everything via a variety…

Drone #4: Power System

Ok. Now I think I understand how the power system should work. Here's a drawing (lines with arrows on them indicates how power flows). So the size and capacity of the battery is dictated by the motors. And in turn the thrust that the motors can supply (which varies with…

Drone #3: The simple physics

So I determined for sure that I'm going to build a multicopter, most likely a quadcopter. A simple model of the physics of the quadcopter is surprisingly simple. Contrary to an ordinary airplane there's only two forces working on the quadcopter: Thrust and weight. Weight is unsurprisingly always pointing towards…

Drone #2

Let's start by asking a bunch of questions: What type should I build? A bit of research seems to hint that a quadcopter is probably the easiest to build as aerodynamics doesn't seem to be as important. And clearly the part I'm most worried about here is the design and…
