We change from day to day in intensity and fervor. We change from month to month and year to year in understanding, comprehension and opinion. One day we are a brick in the outer wall of the church, high up in the steeple where no one sees us closely yet we are closer to God in spirit than those who lie directly on the foundation of the building. A month later we have migrated to the doorway where we greet newcomers with outstretched hands. Those bricks on the outside face the world daily and serve in capacities of service and volunteerism. Inside the building the walls are composed of great formal worshipers who communicate in the Spirit with fire and passion, having more in common with Mary than Martha.
To look at the building is to see something alive – the walls vibrant and undulating – growing larger in times of war, shrinking in eras of peace – built on the unmovable foundation of the the only man to walk on a sea. It lives and breathes and changes its face yet never sways or collapses like structures in the city it occupies.
I am a brick today in the outer most part of the wall – hidden from view, supported by a buttress and away from the fine choruses and ministerial podiums. Alone, yet unalone, I serve simply to stand as a moral example, or spread a trifle charity, or shoulder a crying student with words of a biblical nature. Perhaps to just say, “God please help this person – and me.” Once I served as part of the podium but with little effect. God moved my brick to where it suited Him. I have little honor or recognition yet I am content. My responsibilities are few and simple – to love in action and shine just a little more light in a dingy world. I bring news of a man who defies natural law and death and promises us that we too will do the same. Some have never heard this message and it is my elementary task. I am the brick of the peasant today – perhaps spreading a single seed. Thank you Father for laying this brick so well.
Put couple of LED one meter strings on my wing. Wow, very bright at night and dawn (totally ruins night sight). Much better than EL wire. My LED strings were 3 volt which posed a problem as I had to power them separately from my ESC battery but I had two small 1s lipos that are light and power the strings just fine. I tried using the 6 volts off the receiver but it almost killed my ESC – drew too many amps. I suppose 6 volt LEDs might work but could still draw too many amps. Other alternative is to use 12 volt LEDS and use ESC battery – probably the lightest solution and better if having more than 2 meters of LEDs.
I put the leds face down on the EPP so that they light up the wing more. Need to tape down the wires I guess for less drag. Very little weight added to the wing.
I bought my LED one meter strings (3528) for 11 rmb each (about 2 bucks) which is a whole lot cheaper than US prices that I have seen. Was worth the try. Guess I will keep them on the wing for a while and do some dawn flights since I go out running on the football field at that time anyway before the students start arriving for their runs.
Have a strange problem in that when I solder connectors to the strings and plug in the battery, only the green lights work. The red and yellow just blink on briefly and then go out. Guess the plug causes a touch too much resistance for the current my batteries are supplying (450mah). Not s
ure how I will get around this problem except with larger current batteries. Would be nice to have some other colors on the wing.
This is kind of a mashup of different projects: an arduino to control a servo that controls a homemade Morse code key that controls a simple 4 to 7 component cw transmitter. I will just show some pictures of the various parts and a few comments about each. Please note that operating a cw transmitter generally requires a ham radio license unless you terminate the transmitter with a dummy load resistor to keep from propagating a signal outside of your house. A license is a pretty easy prospect these days since proficiency with Morse code is no longer required.
Why do this project?
1. It is entertaining to watch the arduino control the key with a servo.
2. It is a good practice oscillator for listening to Morse code.
3. It can operate your key and transmitter while you go outside the house and check reception.

I created an Instructable that shows you how to easily convert the Bible (or parts of it) into MP3 Morse Code files. The software is free and so is the copy(s) of the the Bible text files. The benefits of converting the Bible (or any text file) is that you can choose the speed and side-tone frequency.

This is a simple but functional key and code practice oscillator for learning Morse Code made from a steak-knife and multi-tester. Few components and only takes half hour to construct. And when you are finished practicing Morse code you can put the knife back in the kitchen drawer.
block of wood
2 inch binder clip
4 small magnets
multi-tester or volt-meter that has resistance tester (ohm-meter) with sound
I basically got the idea to use a steak-knife from K4IBZ’s Beef Eater Special here: http://oldsite.w4aaz.org/attachments/BEEF_EATER_SP…
There are many homemade keys out there on the web. Even one made from just paper clips.
Here are a bunch of very innovative homemade keys: https://uk.pinterest.com/sverreholm/homemade-singl…
Ok, this is not an original motor design – it has many names, Robert Adams Motor, Bedini Motor, a version of a Mendocino Motor, levitating electromagnetic pulse motor, and there are probably more. But I like my name for my particular version. So.
The electrical magnetic kicker circuit design came from here: trainelectronics.com/…endulum/article.htm
and is easy to build with a small parts count and can be used for other projects. I use mine to swing a pendulum – sometimes for weeks on a set of batteries – just for entertainment.
I tried using an Arduino for a kicker circuit but it can either kick but not sense or sense but not kick without going through some gyrations and then you have to have two power sources – one for the coil and one for the Arduino. No thanks. The dedicated circuit works great.
Here is the schematic of the kicker circuit:
I took these photos about 2010. Don’t know if they are still there or not. Don’t know any details about the aircraft. Just recognize the Chinese trainer. There is another large air museum north of Beijing that is hard to get to but quite interesting and worth the trip.
