Digital Micro Devices (FPV & UAV | Wireless | Displays | Defensa) HXT Simple Lipoly Monitor 2S~3S. A must have for all lipo users! Excellent item, barely weighs 3 grams with leads to battery. I have found that if you remove the SMC resistor connected to the red LED, the LED is ALLOT more brighter. Before I removed the resistor it was a dull red when the voltage drops below 3.3V/per cell, now it can't be missed, either during day or night flight. I also found out that my charger was not balancing my cells properly and one cell would drain faster then the others, this item indicated that one cell was drained compared against the other cells. Save me from completely destroying my Lipo packs :-). One down side to this item is that it does not provide a way to determine voltage between 3.7-3.3V/per cell. Still great tool to have on board.
Quadcopter Frame V1 Yes, this is a great frame to start experimenting quadcopters with. I've build mine with 100pcnt HobbyKing parts, except the control board (= FY90Q) * 4x CF 28-22 brushless 1200kv* 4x Turnigy Plush 18A* 4x GWS HD8040 3-blade (cw & ccw)* OrangeRx Spektrum DSM2 6ch satelite* Zippy 3cell 2200mah 20C* F022 heli landing skid (more solid)* XT60, 16AWG wiring, black M3 Hex bolds & locknuts, etc* Total weight : 850 gram The pre-cut ply wood made the assembly go very quickly and needed just a little tweeking. The CF 28-22 motors are great (you need to dril new holes in the arm) and in comination with the GWS HD8040 3-blade it give loads of thrust. Had 6 flights so far with /- 4 minutes and will try 4000mah later. 1 hard landing but the ply wood frame construction can handle it easily. Will post a vid later :-)
Forum - AeroQuad - The Open Source Multicopter The AeroQuad is an open source hardware and software project dedicated to the construction of remote controlled four-rotor helicopters, also known as quadcopters or quadrocopters. The latest software also support additional multicopter configurations! Buy AeroQuad Parts HereDownload the AeroQuad Software AeroQuad hardware typically consists of the fully-featured STM32-based AeroQuad32 flight controller board or an Arduino microcontroller (Mega 2560 or Uno) as the flight controller board, and an AeroQuad shield with various sensors, such as an accelerometer, gyroscope, magnetometer (heading), barometer (altitude hold) ultrasonic sensors and GPS. Below you'll find an overview of the features AeroQuad offers you: Multiple flight configurations are supported: Development: For information on the development of AeroQuad, see the AeroQuad GitHub Repository, the AeroQuad Developers Guide and our Wiki.

DIY ARDUINO FLIGHT CONTROLLER To Tell you the truth this is not the hard part of this build its actually easy as long as you follow the steps. Prepare the following Print out the PDF in HIGH Quality Prepare the baby OIL Prepare pre synthesized PCB 6x6cm Prepare a container filled with ferric Chloride Prepare a container with developer powder ... 3 tsp developer 1cup tap water (agitate until the powder dissolved) Prepare 10 Florescent lamps Lets start! 1.Cut out the PCB layout and apply a small amount of baby oil and gently spread the fluid around the paper.next gently remove any excess baby oil by wiping it with any cloth 2.Get your pre synthesized PCB 6x6cm, Remove the film and place the print side of the paper facing the green side of the PCB "that is important". 3.Get your florescent lamp and Elevate by at least 3 inch 4.Get your Phone-> clock and then Timer... 5. 6. 7. 8. 9. 10.
Build an Arduino shield for Quadcopter - Arduino Adapter I have been searching for ideas of making a Quadcopter Arduino flight controller Adapter to sit my Arduino nano board and the GY80, also have some header pins for motors and receiver to make the cabling tidy. There are a lot of Arduino shields people have designed for the Quadcopter. I didn’t follow any of the designs. Here is my own build. This design has a few disadvantages, and there are some quick fixes I applied. BEC voltage input The ESC BEC voltage input should have been all disconnected except one of them. I should actually utilize these BEC 5V voltage supply. Motor and Receiver header pins position motor pins should be placed on all four directions for easier access. Microcontroller Socket To implement GPS or sonar on an Arduino nano, UNO or pro mini, we need an additional Microcontroller to interface with the GPS and sonar modules, then pass the data to the flight controller board using i2c. 2 more motor pins (to run a hexacopter) Round adapter board by Warthox.
Quadcopter Dynamics and Simulation - Andrew Gibiansky A helicopter is a flying vehicle which uses rapidly spinning rotors to push air downwards, thus creating a thrust force keeping the helicopter aloft. Conventional helicopters have two rotors. These can be arranged as two coplanar rotors both providing upwards thrust, but spinning in opposite directions (in order to balance the torques exerted upon the body of the helicopter). The two rotors can also be arranged with one main rotor providing thrust and a smaller side rotor oriented laterally and counteracting the torque produced by the main rotor. However, these configurations require complicated machinery to control the direction of motion; a swashplate is used to change the angle of attack on the main rotors. A quadrotor helicopter (quadcopter) is a helicopter which has four equally spaced rotors, usually arranged at the corners of a square body. Quadcopter control is a fundamentally difficult and interesting problem. Quadcopter Body Frame and Inertial Frame Kinematics Physics Motors
AeroQuad Forums - AeroQuad - The Open Source Quadcopter 5 Best Examples of How to Build a DIY Quadcopter | Into Robotics Have you ever wanted to start building a DIY quadcopter and you didn’t know from where to start? You can start from this article and try to build a simple quadcopter. To build a DIY quadcopter you have to combine hardware and software skills, and for more inspiration you can explore all these five examples described in this article and start building your first DIY quadcopters with different features and functionality. Doing research to learn how to build a quadcopter is a time-consuming task and pretty boring. This is one of the reasons that I write this article with simple, cheap, customizable and different multicopters. A quadcopter has a unique design that can be comparable to traditional helicopters, but with improved characteristics for stabilization. Depending on budget, you can choose to start one of these projects that falling in several hundred dollars.
