Yes, it's open source. I will upload it to github and share the link

@@dhruvdroids Wow, I really appreciate your decision. Thanks a lot.

GPS accuracy is around 2m, but it's not the same for the drone. The drone is operating at 5Hz GPS rate, which is very slow for the drone position hold PID controller. As shown in the video, I could achieve a position hold of approximately 10m. But this could be improved by tunning the PID gains. I kept to low to be safe.

Please drop a mail to dhrubadroid@gmail.com

Brother please provide a proper circuit diagram and share us the code if possible😊​@@dhruvdroids

I will compile the code properly and upload to Github

@@dhruvdroids ok boss

Nop

Hi, first of all, try to run the motor directly through a simple code or RC receiver. This will help you confirm if the ESC is ok or not. If its ok then, check when does ur drone code activates the stabilization i.e., the stability code should come into action after certain throttle value, usually 1300 for F450 class drone. If it kicks in right from 0 throttle one or more motor may RPM may go high. If this is not the case, then print ESC signal values of that particular motor and see if it constant always..

Thank you 😊 brother

Brother how to perform pid tuning for ymfc al

PID tuning is pretty much same for all drone. Start with tuning P gain first, keep increasing till oscillations appear. Reduced the gain by 30 to 40 % and then start increasing D gain till oscillations appear. Decrease D gain by 30%. With this two gains you can test fly the drone. Later add a small I gain. You can start with ref PID gains from the YMFC tutorial.

Thank you brother for your help....and i figured it out....now it fly smoothly 🛫

Hi, please take a look at the video no 7 and 8. And also you need to refer Joop Brooking's STM32 gps drone

First, you start by visual inspection. Use some foam or soft rubber, silicon etc. Then increase throttle gradually. During this, you will see the sudden increase in vibration of the controller. It is preferred to have the resonance at lower throttle (below 1300 throttle). Reduce foam stiffness and rerun the test till the resonance occurs under 1300 throttle. Once you have achieved that, you can further plot the acceleration values on serial monitor and modify the foam stiffness according. For hobby related drones, I think the total acceleration should be below 0.1g

Hi Matt. Thanks for asking. Can u connect to my mail dhruvdroids@gmail.com

My drone uses 2 Arduino for the gps hold unlike Joop's STM32 drone. I could somehow manage to get gps hold. If u are following Joop's STM32 design, then my code will not help.

@@dhruvdroids can you provide the schematic and code?

@@dhruvdroids sir , can you plz give the code 🙏

Bro MPU ke lia foam nahi chahiye, mujhe lagana pada becoz mpu hil raha tha socket me. But PCB ke niche slow response foam laga hua hai aur use precisely tune kia gaya hai vibration isolation ke lia

@@dhruvdroids oh I understand 😁

In my work flow 1. I imported the track links such that they had consecutive nos i.e., part1, part2.... 2. There are some py conmands using that I looped once for contact between Track links and sprocket. Then again looped for Track links and idler and so on 3. While creating the contacts ensure that you create their names in line with the Track link nos. That way it is easy to modify contact parameters using a loop

Do send me ur mail. Will send u the commands

Please follow Joop Brookings' tutorial. It's very detailed. Circuit is also available. Uno and nano are exactly same in terms of pin connection

Its difficult to give an exact solution. But does it flip immediately on flight or randomly during flight. It's possible that you MCU is getting reset. Try powering it directly from the battery.

Also. If it flips immediately on power then ur props direction could be an issue

@@dhruvdroids i checked prop direction it's according to joop brokking video

@@dhruvdroids It flips immediately

Prop n motor direction both need to be correct. For instance diagonal motors need to have same rotation sense

Yes, it should work with the tri 6045 props

Haha yes indeed it was unwise of me to use that. But I got a fresh bat in the final build

Its reasonably good. The 5inch quad flies well. Infact I find the thrust a little uncontrollable beyond mid throttle. The motor-6045 prop combo generates higher thrust above mid throttle. I have not measured thrust but Estimate its 400-500gram

Code plz

Hi, I implemented Joops code in Arduino unlike STM32. I had to strip down the code to bare minimun to run. In Joops original code the gps is sampled at 5hz and then interpolated to achieve 50Hz sampling. In my code the 5hz is the final rate. It will be difficult to do the 50hz in an Arduino

@@dhruvdroids do you still work on this project? i manage to make it work in a teensy 4.0 but the quad sometimes stays in position and sometimes roams around 3m diameter. Can you suggest a better approach?

@huntervoid5927 I am not working on the gps project but I faced the same issue, mine was around 10m circle. It's all related to the GPS refresh rate and GPS precision. NEO7M series GPS module allows 10HZ refresh rate. That should make your drone position hold more stable. Additionally, some assistance from the accelerometer is preferred.
