Chapter 1 - Ohm's Law

Confused? Don't be. This past weekend, I had the great experience of attending EAA's SportAir Workshop - "Electrical Systems, Wiring & Avionics". On top of that, the workshop was held at Flabob Airport (RIR), home of EAA Chapter 1!

Ahh, Brings Back Memories - LOL!

There were a number of workshops held at the same time during this weekend. In addition, there was a "What's Involved In Kit Building" session held Saturday evening with a pizza dinner. Quite a bit of information was given out regarding all aspects of planning, selecting, building, completion, flight testing, operating and references for your own amateur-built aircraft. One big thing I took away is that when you're interested in building your own aircraft, you should seriously consider ordering the $13 (for members) "Amateur Built Certification Kit" from EAA. The kit includes everything you need to register and certificate a new experimental amateur-built aircraft. I'll have my check in the mail very soon for this little gem. It'll save a lot of time and headache!

The Electrical Systems workshop was a lot of fun, very educational and quite informative. Our instructor was EAA's Kas Osterbuhr. He's a very knowledgeable guy with a lot of wiring experience. I've seen a number of his "Hints for the Homebuilder" videos on the EAA website. I highly recommend all of the Hombuilder videos as they are chock full of information. Check 'em out!

Our Instructor, Kas Osterbuhr

There was a huge amount of information covered. There are a lot of things to consider when designing the electrical system on your plane. You need to think of how everything will be connected and how things will work without having any problems or issues and something that will last for the life of your plane. Are you going to build for VFR day or night? IFR day or night? What kind of panel will you have and how will it all be connected? I learned you should take some butcher paper and layout your design. Take your time when laying things out. Well, that's a given in ALL aspects of your build. A good layout will help you a great deal and save you a lot of time down the road. Kas also reconstructs aviation accidents. Some of his information from accident reconstruction makes you stop and think more carefully of how NOT to put yourself in a situation that could go bad. Be smart!  Document and diagram all of your build very meticulously. It will be of great importance should you ever need to go back to something for a fix, repair or change later down the road.

I've never really learned much about electricity or its theories. Kas mentioned, and I agree that this course should be divided into two courses, a beginners and an advanced course. That said, I was able to muddle through and learned about electricity from the "physical" perspective, volts, amps, ohms, watts, capacitors, switches, diodes and what they all are and how to work with them, hence, Ohm's Law (Volts = Amps * Ohms (V=IR)).

I won't go into details here because I'm still trying to wrap my head around a lot if it. Good thing I received some valuable reference material to get me started! I plan to get a "Dummies" book to have on hand to fill in the blanks (wow are there are a lot blanks right now...).

We learned soldering, wire termination, installing various types of connectors and understanding when and where to install the right types of connectors. In addition, we received a ton (well, a bunch anyway) of reference material and all the tools you can expect to need/use when it comes time to start electrical installation. Oh Boy! Here is some of my handiwork:

First Major Project - Intercom Wiring
with a D-Sub Connector

Wire Stripping by HAND! Satisfying When Done Right :D

The Same Antenna Cable From Above Terminated with a BNC Connector

And the Final Project - A Panel With 2 Lights, One Dimmable.
The Instructors Model Shown on Bottom, Mine on Top. It Worked!

 After constructing the "Instrument Panel", you need to go through measuring various information such as dissipation with various power settings, voltage, resistance with various settings, how much current draw, etc. There is a lot of information to consider when building your own panel and plane.

Well, I can't wait to get started! Turns out that the person interested in my '72 bug declined to make the purchase. That said, it looks like my empennage purchase may be a bit delayed. No worries! All in time. I was merely looking to save a few bucks before Van's pricing goes up next year. I've heard that prices go up early in the year but not sure. If anyone can confirm that, it would be very appreciated.

Well, that's my story for now and I'm sticking with it! Take care and Thanks For Reading!

Status, Workshop, Patience

Hi Gang! First, status. I've been chomping at the bit to get the empennage kit ordered. I've also been over anxious to get my tool kit ordered. The emp kit is currently pending as I'm waiting to get my VW Bug sold. I'm driving it in to work this Wednesday for a potential buyer to take a look. When it's sold, cha-ching! It'll go to the purchase of the tail kit. As far as the tool kit goes, I was very tempted to put it on a credit card last weekend. I slammed the brakes on that  decision as I don't want to have any major debt starting to pile up on this build. That said, I've made the decision that if I can't purchase with cash, I'll wait, hence the Patience. So, saving up is the right thing to do and peace of mind at the same time. It's not a race, no rush, take my time, etc. After all, I'm still young... right? Right! 

Now, EAA Workshop. I've signed up for the "Electrical Systems and Avionics" workshop that will be held in Riverside, CA., 11/19-20. In addition, there will be a "What's Involved in Kit Building" session Saturday evening. I don't think I got all I really expected at the Van's Assembly workshop I recently attended and this presentation promises to deliver all the information that I missed. "The goal of this seminar is to take you through the entire building process, discuss the relevant FAA rules (in plain English) and to dispel some of the common misconceptions involved in building your own aircraft. This seminar is invaluable for anyone desiring to build an airplane, either kit or plans-built". Other things that will be discussed are insurance, regulations, the build process, timeframe, and other things one should know before embarking on such a huge project. I work with a friend that owns her own RV-6 and is very interested in going to the 2-day seminar so she can become more familiar with electrical systems and avionics of her airplane for the benefit of inspection, repair and possibly replacing components. If she does sign up, I may fly down with her which ought to be fun. Maybe I can even get some stick time in an RV which I've yet to experience.

Patience is a virtue. At least that's what my Mom has been telling me for years! Some people have it, others wish they possessed it. I'm a little of both. I have patience but it sometimes takes me a while to pause and reflect then go out and make the right decision. It's taken most of my 48 years to learn this but I think getting better at it. You'd have to ask my family and my wife about that! Creative Financing is also something I've been learning for a long time. I believe I've come up with a plan that will help get more of my project launched sooner than I had expected so we'll see how things go.

That's about it for now so thanks for tuning in and Thanks for Reading!
