RC Tips: Adding any LED to your model.
Where to place Ferrite Choke Rings on FPV kit? There seems to be some confusion about peoples answers, definitely near the receiver, near the servo.
Perhaps a bit of understanding will help, a wire will naturally act as an antenna picking up various RF signals or as we see it interference (RFI), likewise a wire near a magnetic field will induce an electrical current. A Ferrite choke is designed to breakup the RFI that is collected on a wire and wait, wait, wait, CHOKES the RFI from continuing along the wire. Thus the placement of a FC depends on what interference you're trying to solve. If you have servo twitching, placing a FC near the RX would be useless, since the interference would come from the servo line into the servo and never get choked. Let’s Do the Twist. June 1, 2004 for QuietFlyer Magazine In an electric model, the possibility of the electric power system interfering with the radio control system has been greatly reduced by improvements in receiver technology in the last decade.
However, interference can still happen, especially if care is not taken in installing both systems. Electricity and Magnetism Both the power system (motor battery, speed control, and motor), and the radio system (receiver battery, receiver, and servos) use electricity and magnetism to do their work. Glitch Free Installatiions - FPV Wiring Best Practices to Reduce Interference. Electromagnetic Interference Reduction. May 1, 2000 for Sailplane & Electric Modeler Magazine Electric model aircraft are generally very quiet, so it’s somewhat ironic that one of the biggest problems in electric flight is noise.
However, we aren’t talking about the noise that you, I, or our flying field’s neighbors hear. Instead, it is electrical noise, which is only heard by the electronic equipment in our planes, which is the source of potential problems. Just like audible noise is any unwanted excessively loud sound, electrical noise is unwanted excessively strong electromagnetic radiation.
Electricity basics for RC fliers. ESCs. Electronics 101 - What is electricity? How to Power the FPV Camera and Transmitter - RC Groups. Sure, you can power off the main flight pack, I have been doing that ever since I started this hobby.
You need to realize though that an ESC generates quite a bit of noise on the supply rail and if you don't get rid of that it will be visible in your videos. A simple linear voltage regulator usually works well if you need to power a 5V camera off of a 3S (11.1V) pack. It simply converts the excess voltage into heat and thus usually requires a bit of additional cooling. The added advantage is that in essence they act as an RC (resistor, capacitor) network (the voltage regulator can be seen as a variable resistor), significantly (up to 60dB) attenuating any noise on the supply rail. What does the ring on ESC do? - The Ferrite Ring - Oscar Liang. Occasionally ESC signal wire is wrapped around a little doughnut ring, for example on the Hobbyking 30A ESC.
So What does the ring do and is it necessary? Published on 14/02/2014, last edited on 04/05/2016. This mysterious ring is called ferrite ring or ferrite bead. It is used on ESC to reduce noise caused by the long signal lead. ESC signal leads can behave like an antenna and picks up all sorts of noise, the longer the worse it gets. Ferrite Rings on ESC's: What Do They Do and How Can You Use Them? - RC Heli Nation.
A quick note to clarify the need for and use of ferrite rings… The ferrite ring acts as a common-mode, inductive filter of the high-frequency noise produced by the switching of the MOSFET’s inside of the ESC.
Basically, it prevents the AC current fluctuations inherent in MOSFET switching from progressing beyond the ring itself (it actually looks like a big resistor to high-frequency currents and doesn’t affect DC signals at all), thus eliminating the potential for making your ESC signal wire an antenna that radiates at the frequency of the common-mode noise. It also prevents that noise from getting into your receiver or servo signal wires. Wait a minute…that first paragraph was filled with a lot of crazy science words, so what the hell does all that mean?!
You can think of your ESC as a big valve that supplies electrical current to your motor. Filtered power source... - RC Groups. How to Power the FPV Camera and Transmitter - RC Groups. RC Battery Connectors - Radio Control Info. RC Battery Connectors In the application of electric motors and batteries, connectors play a large role in transfering the battery power to the motor and through the ESC.

Look at all those exposed wires and connectors! Choosing an RC connector - TJinTech. In the old days There used to only be a few RC connectors to choose from.
Some may remember Tamiya plugs, I know I do, and others may remember some other odd connector that seemed proprietary to some brand. Others will remember Power Poles, as they have been around for a long time but were, and are still, not designed for hobby use, even though they work well enough. In short there just wasn't a huge need for RC specific connectors, so generic electronic connectors seemed to be what everyone used. Sometime in the 1990s, I think, W.S. How to Prototype Without Using Printed Circuit Boards: 8 Steps. In addition to the perfboard and a soldering iron, you'll need some fairly common tools and supplies: Kynar wire: This is an insulated 30-gauge single strand wire.
It's a rather thin wire which is useful for low current and low voltage digital circuit connections. I use three colors: Blue for Ground, Red for +, and Orange or Yellow for all the other connections. RCTimer/Turnigy/Hobbywing ESC DIY Firmware Flashing. Thanks to the help of timecop (yes he can be nice as long as he is interested ) I managed to flash my RCTimer 10A and 30A ESC. The procedure should be the exact same for the 18A and 20A versions. IMPORTANT: BEC on ESC and Avoiding high current system ground loops. If there ever was an FPV NOTAM, this is it.
This has to be shared asap. I've seen one too many burnt current sensors and potentially damaged OSD. The reason? Ground loops sharing high ESC current. How to power wireless video camera systems with best results. Dimension Engineering Switching Voltage Regulator Application Note How to power wireless video camera systems with best results Overview This article will show you how to use a DE-SW050 voltage regulator to power a wireless video camera system in your R/C plane or car.
This way, you can run a system with only one battery pack - you will not need to carry around a separate battery to power your video system. We will use a DE-SW050 because it can take a higher battery voltage and regulate it down to the 5 Volts that is needed by most wireless camera systems, such as ones offered by Black Widow A/V or Range Video. Some camera systems require 9V or 12V, and in this case you should use a different voltage regulator, such as the DE-SWADJ or AnyVolt Mini.
