Replacement of Potentiometers in Turnigy 9X with Hall Effect Sensors

|
+1
Due to age and/or plain poor quality, potentiometers in transmitters tend to gradually fizzle out and potentially cause your most favorite model to crash to death. You can either replace them with new ones or install hall effect sensors instead (named so after a person, not the room type))) and never have to meddle with it again. Here is a list of items we’re going to use:

1. SS495A1 Hall Effect Sensors or similar ones
2. Strong rare earth magnets (10 per package) I used circular magnets, going linear and so all the way down, then shift the magnet’s center a little off from the roll axis. That’s it.
3. A soldering iron (flux and solder alloy)
4. Servo cables (or similar ones)
5. A small cross screwdriver
6. The dexterity of hand)))))

Here is a vid just for a start

"The Hovercraft"

|

Technical title of the project: NaSRu VeSDe (Nanotechnology Supersonic Russian Very Strong Destroyer). Even looking at non-standard vehicle - it is always interesting, but to build with your own hands custom vehicle even more interesting. To this day, I have never designed the hovercrafts, this is the first time. So in this article I will tell everything. Something I managed to do the right way immediately. Something I completely failed. But on some units and mechanisms I had a lot of work. From the theory of hovercrafts I knew only one thing: the hovercraft is lifted by air pressure under the bottom. Therefore, to create maximum pressure, I chose rotor with a lot of blades. Theoretically a rotor with a lot of blades should create a sufficient pressure underneath the hovercraft.

Stand for testing of brushless motors (part 1)

|

I noticed that it is very uncomfortably to use separate devices for testing of brushless motors (servotester, wattmeter - for example). There is a problem: something constantly tries to fall down, wires are got tangled and are trying to make a short circuit. An idea has come to me: combine everything in one device.
I live in Siberia. We have a long winter so in between drinking vodka and walking with a bear... (about vodka and bear it was a joke). One winter evening I had engaged in manufacturing of this device.

Black kites - a beautiful carnivorous Siberian birds. In the summer they always accompany model aircraft in flight. The idea of the film "Black kites in flight" appeared by itself. Black kite is one of the most beautiful birds of Russia.

Hi, everybody! Yesterday I have lifted in the air new Al-609 Dominator model! It flew and flew not too bad. Further it was the period of tests and adjustments before coming to the level of normal pilotage.

I'm in the 10th grade and there are project activities in our school program. I have chosen the topic of physics and wrote about brushless motors. I would like to tell you about my project in this article.
