Add-on Accessories

This page describes the optional features of the ESPcopter beyond what is necessary for flight.

Fig 1

Above shows one of four LED strips, two green (forward) and two red (aft), that will be added under each motor arm in order to increase visibility from the ground. The strip has high intensity LEDs on a printed circuit that has been waterproofed and backed with an adhesive strip. I got them here. Code has been added to the AeroQuad code base that allows for various blinking rates and patterns.

Above is a picture of a camera mount. It is based on a design that is open source, (thanks, Matt!) but modified to be cut out with a .125 bit in .125 Lexan. The opening is about 2.5 by 4 inches, easily big enough for a Go Pro, which is only 1.6 by 2.4 and 1.2 inches deep. It has stabilization servos to compensate for variations in pitch and roll (not shown above) while in flight.

This is the GoPro HD video recorder, a remarkable little device, shown with a one inch bolt for scale. Now that I see its size and weight, the camera mount above seems a bit overkill, so I may look at another. This device not only records 4 hours of 1080p video, it presents a 640x480 video signal of the same image that may be transmitted to the operator.

Fig. 4

This is a Vx/RX (video transmitter/reciever) pair operating at 5.8 GHz. The receiver is on the left. The transmiter weighs 40 grams including the wires shown. I will make a harness that plugs into the GoPro and connects to the transmitter, although I may want to put an On Screen Display device between them that superimposes HUD style flight data over the video signal. I will probably also make a power supply to go from battery voltage (about 11.4 volts fully charged) to 5v regualted with a filtered output.
