How to Build Your Own Flight Controller // The Anatomy [Part 1]

[@logandihel]

Just putting this out there - the D+ and D- on the USB are not TX and RX. They are differential pair signaling, where instead of sending a HIGH or LOW on one trace to indicate a 1 or a 0, you send opposite signals on the D+ and D-, and the microcontroller uses the transitions to determine if a 1 or 0 was received. This practice is done because it is much less susceptible to noise and enables high speed communication.

[@raphaelho1791]

It is the most educational video I have ever watched over the last five years. I am so beyond impressed!

[@channeleverything3420]

DUDE!! BEST VIDEO ON KZbin! I HAVE ALWAYS WANTED TO DO THIS! GONNA WATCH THE REST OF THE SERIES AND THEN MOVE TO THE ESCS!!!

[@xerovolume3321]

I've never felt this anxious for a youtube video series in all of my life!

[@amphem]

LEDs are suicidal is what made me subscribe. I know totally nothing about electronics, you made me want to learn more. I wish I had a teacher like you about 20 years ago when Internet was still crawling.

[@netpro2k]

Excited for this series. Really hope you dig into the datasheets for eveyrthing in the future videos, would be really nice to see the WHY for every capacitor/resistor/etc.

[@TerryDavisMedia]

@@arloblaze9844 yup, been stroking the chicken myself since birth :)

[@brunogp8269]

A DIY F4 and F7 kit would be a great idea. I would buy!

[@WildCaptures]

Bruno GP I second that✌️

[@MrMarcosyMrsLaura]

Me too👆🏼

[@tutacat]

Well, the crystal controls the clock of the CPU, that is what tells it to advance and count up to the next instruction. If you unplug the battery, can you not use the USB input voltage then

[@dschingis3094]

The 0.1µF and 1µF caps on the VDD pin of the gyro should be in parallel to gulp up different frequencys of noise/ripple having them in series will give you a higher voltage rating but less capacitance overall. But still a great video :D

[@henrynel5197]

Knowing this is worth gold. Keep it up !

[@jaynay52]

Stumbled upon this video looking for some answers and you knocked it out of the park. Awesome video man!

[@pianojacq]

That 1 u / .1 u arrangement in series makes no sense to me, what is the datasheet that you refer that that that came from?

[@fatherofrobos3573]

very interesting, the best series i have ever seen in. keep it up

[@TopFlightAero]

Thanks!

[@ChrisLBradly]

your channel is awesome! making builders into designers and creators!

[@WildCaptures]

It is very cool to learn what each of these components control and how they work together😊👍🏻

[@mccolld11]

This is great stuff. This project provides an opportunity to create a design superior in every way (performance & components) to anything on the market because salability and profit are not part of the equation. I hope that's how the project evolves into the "ultimate" design. I'm learning more about electronics than ever before. Keep up the great work!

[@Nick-wj5gw]

One of the best Playlist I've came across in a while. Definitely will be doing this design. Thanks man!

[@mathssoso4261]

Thank you for sharing this with us. What is the LED in Pin 14 of the MCU for ? there is no third LED on the schematic. I am not sure if you mentioned where to put the GPS? The pins can be either labels or ports , are the UARTs, the SBUS, SDA/SCL pads ports or net labels ?

[@impmeister1]

Once in a while you stumble on a jewel of a video. This is one of those video gems I used many MCU's and wanted to try the stm32 ones. ordered a nucleo develepment board etc. this would be a sweet first project with stm32 mcu's thank god I googled AT7456e (osd overlay IC) and this video showed up. Subscribed an will watch the other videos, thank you my friend!

[@maelremremxyz]

Nice work ! I was making my own FC and I came on your video. I will make my based on your work but the layout will be different ! Keep up the good work !

[@atnosfpv9749]

Tiens tu est là toi :D

[@minghust9098]

Can you program the MCU using the USB port? I see your SWD lines aren't connected to any external connector so I'm curious as to the process. Thanks

[@drids_fpv]

Amazing project dronemesh! Like the idea of making a kit because many people don't have all the spare components that go on the pcb. Can't wait for the next videos of this series! I learn a lot, thank you

[@quickf0x792]

Are you interested in making a custom firmware/ forking betaflight to include gimbal support and quaternion controllers?

[@DroneMesh]

Yes

[@quickf0x792]

@@DroneMesh what code does betaflight run on.... If I were to pursue this project, how should I start, could you(or anyone who reads this) give me advice on tutorials on how to start? Also I'd love to make this compatible/tailor made with you flight controller if you were to make a 20x20 version with an osd, 5v reg and some other common features.

[@shri3141]

Well you should start by going directly to their website.Then you can find their opensource code and start learning them, there is also a bf slack group which would help you, basically bf is coded by c , in K and R indendation style, make sure you stick with it.If you propose an idea , you can start working on it by making hex files and sending them in the channel, there are a lot of testers.Good luck

[@quickf0x792]

@@shri3141 thx

[@varunahlawat9013]

I don't think that at 17:53 you really need to do explain it that way. It's just a voltage divider, so that not all the voltage is dropping across the boot pin, some is going into the ground, and how much should go into the ground(I'm assuming out of 3.3)... I'm commenting this to see whether or not I got it right.

[@LordLT13]

i was looking at your schematic and was wondering if you had put motor drivers in your schematic. I couldn't find them anywhere

[@aviralshukla5656]

Really excited to watch all the parts of this series!

[@farziverse4209]

There is no receiver on the FC either, how will it connect to my RF transmitter?

[@farziverse4209]

oh so he has given UART ports, and then I can connect my receiver to it

[@Rundik]

He explained in detail what a gyroscope is despite everyone knows what it is and all he said about the resonator is that it's important

[@zephyrflyer629]

Where would you be able to give the schematics and get it assembled with all the components as well?

[@user-bp5tg3yd3d]

did you find out?if you did can you tell me

[@KolibriFPV]

This is really great! I have been quite longing to bulid my very own flight controller and you just jumped right in. Will dive deep into your vids. Thanks!

[@hassanoukaddour9434]

What a eye opening video!! I never knew i could start knowing how this all works.... But I do now! thanks a lot bro I'm getting smarter each day

[@mahanths1353]

This is just something I wanted. It's impressive how knowledgeable you are helping out the community helping out hobbyist like me to get deeper into hobby. I'm truly thankful for that. I just had few questions about the software which is used to sketch these circuit. What are these programs called?

[@JG-nm9zk]

USB doesn't have tx and rx pins. They have D+ and D- which are a differential pair. Both are used for communication in both directions.

[@JG-nm9zk]

guess you cleared that up in the schematic talk.

[@EJ3.16]

Very good very nice video,, I have a question I have a xk x130 drone it use 1S lipo can I put 2s for more power but how can I know without fried all the system please help if you can tell me please thank you...!!!!

[@brookshank]

What is the resonator used for with the gyroscope? Is there somewhere I can read more about that interaction? I am having trouble finding out more about why I would need a resonator.

[@hmbiii9974]

QUESTION: Can we use STM32F405RGT6W MCU 32B ARM Cortex-M4 1Mb Flash 168MHz CPU ??? Didn't know if this would effect the installation.

[@MCsCreations]

Fantastic start for the playlist, dude! Thanks a lot for all the explanations! 😃

[@yehonatanbellaiche9359]

great video, maybe you can design a receiver (from a chip) and teach us how to do that. I think a flysky 2.4ghz with telemetry and diversty would be great, there isnt flysky reciver with this specification.

[@darkshadowsx5949]

where did you go to school for electronics? im in the states and always heard them called crystal oscillators never really resonators. also i have a 12v NCP1117 on one of my projects and all it does is drop the voltage by 1v. its setup as per datasheet with the 2x 10uf capacitors and im confused as to why it wont work correctly. it would be awesome to make my own FC boards once the chip shortage is over...

[@milaanpatel4997]

Really great video. I actually want to build one myself. Given that i have minimal background in electronics this video is really supportive.

[@kartikpandey5335]

How can we make a FC like pixhawk cube 2.1 for the commercial usage? they have license on each part what does that mean?

One question please, is your controller programmed with Betaflight programs, inav... If not what solution?

[@andrewtran940]

How do you know which pin to connect on the STM32F405? or we can do it as the way we want ?

[@sangarp2001]

Is there any other flight controller for bicopter and coaxial rotor heli? I am using kk.2.1.5.

[@simonginzel3143]

is there any document that specify the pin assignment of the Mikrocontroller for the beta flight software?

[@shri3141]

Icm is not a noise sensitive gyro, if wired up correctly it is a good clean gyro.This is being mistaken.Take a look at cl racing f7, its not prone to much noise eventhought they use icm.I dont think your fc have flash memory, flash memory is a component that stores codes, yeah thats a prominent component in an fc, you cant basically store all the codes in your mcu, its also kinda dangerous to do so.

[@shri3141]

@ 5:52 you have a flash memory chip above the usb(molex)

[@KrotowX]

Did you seen a MultiWii type flight controller who store firmware and settings outside microcontroller chip? That external 1-wire memory chip is intended to store Blacbox logs.

[@gamaxgbg]

hey, can you answer me a question not related to this video? i want to know if it is possible to change the motor wire gauge. I have a motor with 20 AWG and wanted to change to 18 AWG, how can i do it?

[@Bill-qo2jb]

Great video, but why did you connect capacitors C13_G and C6_G in series, and not in parallel ? Doing so, they are equivalent to only 0.09 uF, and you do not have the benefit of filtering out more frequencies in power supply voltage (by using them in parallel).

[@pianojacq]

yes... I thought the exact same thing.
