Help needed for drone simulator for Mac
Project help: Problem with connecting tx(avionic rcb6i) as a joystick to my Mac using aux cable! Does anyone know any suitable driver(to recieve and decode ppm signals from tx and encode and transmit ppm to tx)?

Hi @iero , Any updates?
I dropped the idea of using simulators and learn flying and to do acrobatics (Because of the trouble I got while connecting my old TX to Mac)
meanwhile, I tried flying my drone(that I build) outdoor, I know it's gonna difficult, I know it will crash for sure, but it's okay if it crashes I will build again and will fly again so I can learn from that.
but due to the academics, I didn't get much time to fly. and last time I flew, it crashed like a hell, damaged a lot of parts but I rebuilt it successfully,
Now it's ready to fly and I'm sure I will fly again
Sharing some photos of the build
As a student spending money on website hosting is really a big problem, and Thanks to GitHub pages now we can host our website for free thanks @salmanfaris for this article, looking forward to see more useful article like this
@Ggreeshma-stani Nailed the PCB in terms of the schematic. But you got it a little bad on the layout side. There are some thumb rules while designing a layout of PCB.
Always place the oscillator and it's capacitors(C1, C2) near to the IC. If you have a doubt on this try checking the Arduino boards or any other boards. you will find an SMD chip crystal alongside of the Arduino XTAL pins. If you ask the reason for this that's simple, to avoid noise creeping in. Crystals provide the clock to the entire digital logic inside the IC. So, there should not be any noise in it. If noise is there, obviously you'll have timing issues.
The bypass caps on the voltage regulator must be placed close to the regulator's input and output pins. The reason for this is also pretty simple, bypass caps will filter out noise coming from the power supply and few other reasons too. So, try placing these bypass caps as close as possible to IC.
Apart from these points, the PCB looked good. Great work. Remember that this message is not to discourage you but just to give a suggestion so that you'll improve it in the next design.

@salmanfaris the pressure range that we have to measure is between 5-10 cmH20 (ie almost 0.07 - 0.0.14 psi)
