By the time, my AAT (Automatic Antenna Tracker) need some improvement/upgrade.

I have first the idea to upgrade pan gear as mine was only a timing belt which tend to jump some teeth and don't do the job for heavier antenna.

the old timing belt :



I got a set of gear from Charles at MFD, but it need some machining to put on the gear :

I made an antenna mount for UHF antenna, it should be very helpful for mutlirotors owners. The antenna can be dissembled for transport, just 1/4 turn release and perfect polarisation.

Hi,

I add a nice feature on my FPV penguin, it's a quick release canopy like on the pic below :

Rear :

For my back pack fpv hexacopter, I use the driver only and pick from it the gps coordinate, and send it to an arduino UNO board with lcd shield to display and keep the plane location

I put an old myflydream driver with an arduino UNO + shield in the same box



here is the code I use, gps tx connected on pin3 :

Quote:

#include <SoftwareSerial.h>
#include <LiquidCrystal.h>
#include <TinyGPS.h>


LiquidCrystal lcd(8, 13, 9, 4, 5, 6, 7);
TinyGPS gps;
#define RXPIN 3
#define TXPIN 2
SoftwareSerial nss(RXPIN, TXPIN);
void gpsdump(TinyGPS &gps);
bool feedgps();
void printFloat(double f, int digits = 2);
void setup()
{
Serial.begin(115200);
nss.begin(38400);
lcd.begin(16, 2);
//Print a message to the LCD.
lcd.print("Elaboration");
lcd.setCursor(0,1);
lcd.print("coordonnees GPS");
//We test the version of the library
Serial.print("Testing TinyGPS library v. ");
Serial.println(TinyGPS::library_version());
Serial.println(sizeof(TinyGPS));
Serial.println();
}
void loop()
{
bool newdata = false;
unsigned long start = millis();
while(millis() - start < 5000){
if (feedgps())
newdata = true;
}
if (newdata)
{
Serial.println("Acquisition Data");
Serial.println("-");
gpsdump(gps);
Serial.println("-");
Serial.println();
}
}


void printFloat(double

Flying in an area with a lot of interferences, I found an idea (not new and use by professionals), why not killing the parasites with a band pass cavity filter.

I found one on ebay, I modified it to suit 1010Mhz (a spectrum analyser is needed for that), it's the blue thing from REACTEL.



I made a test video, with 2 VTx emitting at the same time, on for simulating parasites (800 mW at 980 Mhz with a dipole) and one for simulating a long range plane flying away (200 mW at 1010 Mhz with a dummy load on it).

I'm very happy with it, just look at the result, first test a good Vrx (lawmate) with no cavity, second test RMRC with the cavity filter.
Cavity Filter (1 min 9 sec)


The test

Conclusion, some more professionnal than me could make filter like that for specific frequency, that would be very usefull for us. May be IBcrazy ?
