In the first series of this setup, Oscar Liangbuild this DIY project using the TX5823 and 1g camera. Though the result was satisfying as its small size and light weight efficiently carried the mini quad and had a decent flight time. But the noise triggered by the motors indeeddisappointed this FPV arrangement.
Various attempts were taken to curb the noise, for instance, building of a power filter, but were not of much help.At last, the project landed up by using a separate LiPo battery to control this 5.8 GHz FPV setup. Though the battery is light-weighted but the heaviness of the FPV setup has augmented to a total 12g. The other options available are expensive but protects your anxiety from DIY.
In this latest version of the FPV combo build, a second micro FPV setup is arranged by using a much improved mini video transmitter with in-built power filter and voltage regulator. Further, a cheaper version of mini FPV camera is used to balance out the additional cost by the VTX. The result is amazing as you can securely power this FPV combo via the main battery, and it’s noiseless and the total weight of this operation is 6.5g, almost half of the earlier version.
AltitudeRC 5.8GHz 25mW Nano FPV Transmitter – FatShark Compatible is used as a main component of this project as this VTX has the built-in power filter and it certainly helps in reducing noise in the power. This VTX scores on analtered frequency band (Fatshark, ImmersionRC band) than the TX5823 which is the Boscam band.
The heatshrink is removed and the antenna is cut down as short as possible. The package noticeably displays you how long you must cut the antenna to. The next component used in this project is 600TVL 120degree Wide Angle Super Mini FPV Camera with MIC, which comes in a 170 degree wide angle lens, and it’s only 1/4 the price of the 1g camera.This camera comes with a Mic for audio. But it is removed along with the green and white wires (audio output) to reduce weight.
As the AltitudeRC video transmitter has a voltage output devoted for the camera, which is rated at 3.3V and is perfect for this project. Further the power and ground wires are also twisted to reduce noise in the power. For more details, visit the following link – :
