Hey! Got some updates for you! They were all too small, so I decided to wait till now to tell you. First, model railroad fans rejoice! I finally updated the model railroad stuff. Scroll down to the end of this post if you’re interested in only that. But I hope you’ll read on…

 First fabbed PCB boards!

Circuit Boards!

Yes, I finally have created and gotten my first fabbed circuit boards! I’ve worked with electronics for a good while now, and always avoided getting a ‘pro’ looking board, due to the high costs. But, I finally found this awesome place called smart-prototyping.com. For only $30, I got ten of the circuit boards (including shipping) as you can see above! The service is decent, and was able to get the very thin traces I made. I’ve assembled it, as show below: Read the rest of this entry »

Welcome back! So, if you’ve read the title, you may notice that the last idea was a success! Well, sort-of. Lost on what I’m talking about? Catch up on the Building Quadcopter series with these links:

[ Part 1 –Theory and Controls ]

[ Part 2 – The Body of the Quadcopter ]

[ Part 3 – Bring the Pain ]

[ Part 4 – On Standby ]

[ Part 5 – PID problems ]

So when we left off last time, the main problem at hand was PID control. Through some testing, I found that the PID controls were working ( although, DA’ QCB controller was experiencing some windup ) With the PID controls verified, what could be the problem? The frame, motor, and/or propellers? This is where I was stuck until I tried my final idea to the problem:

There’s snow and ice where I live, and I live in the south. South + snow + ice = everything shuts down. In the meantime, this was perfect for finally getting to scrapping my semi-old Dell printer, as I got a new one, that uses easier to find ink (and cheaper).

Its mostly a photo-style blog today, so enjoy:

The Dell printer to be scrapped today!

Quadcopter Problems, circuit boards, and where to go from here? That is the topic for today’s post.

First off, hello again after the long break! To get down to business though, this quadcopter project has been holding me back on many project things. For the model railroad enthusiasts, I’ve worked more on the layout, and have two buildings so far. I’ll get to them soon as I can in the coming weeks.

So the title is, PID problems. This has been the focus of the problems from the quadcopter, for the last few months. It isn’t the only cause, but seemingly is the only thing keeping the quad from leaving the ground.

What is PID? Well, to put it simply, it means Proportional-Integral-Derivative. This is used in many control systems for electrical circuits. You’re A/C controller on the wall probably has a PID controller. Your fridge/freezer has a PID controller. Same goes for your car and other various electronics. In short, a PID takes an error and compares it to a set point (i.e., your thermostat is set at 70 degrees F). If the error is too low or too high, it adjusts the output of the controller to bring the error to zero.

If you missed it, the quadcopter project is on hold.

Nevertheless, I have been working on a few other projects. Before I get to those projects in the coming days, just a small update on the blog:

Check the Model Railroading page! Big update has been made! Model Railroading

MiddleWood and SPbrown Layouts have been added to the Model Railroading page. SPbrown is the current layout and is still being worked on. Who knows, maybe I might have a post on it soon? (hint, hint…)

Eastern FireTail

Hey there! Well it seems the post “bring the pain” still hasn’t ended for building the quadcopter! Today, its “ON STANDBY” But before I go into that, if your just tuning in, make sure to check the previous post on the Quadcopter first:

Part One - "Theory and Controls" ]

Part Two - "The Body of the Quadcopter" ]

Part Three - "Bring the Pain!" ]


The Problematic ESC

This is my build log post on the quadcopter. Today is the introduction of almost flying the craft, but held-up with just a small problem: Stabilization.

If your just joining in, make sure to catch-up on the previous two parts of the Build Log:

Part One - "Theory and Controls" ]

Part Two - "The Body of the Quadcopter" ]

Ok, continuing on, if you haven’t caught the name of the quadcopter yet, it’s name is: Black Dragon. Due to how evil the stabilization tests have been, and for the fact that the color of the craft is black.

If you haven’t caught the video, here’s me trying to fly the quadcopter without any stabilization. This is why I need to build a test platform:
