one thing to note is that i have more solder than needed because i found that the motor wire is too thin and if i don't solder part of the plastic with it, it moves slightly and eventfully break off.

There also to discuss here but generally, everything is global. i know that's a bad idea structurally and i plan to change that at some point. the part where pretty much everything happens is the adjust() method. it does the reading of the gyro, the pid and the motors write. so after we read a...

Hello everyone. long story short, im trying to create my own flight controller for a project and testing has been a pain. im wondering, is there a simulation out there that i can give Arduino code and quad copter specification to see how the quad would generally behave? it would really be a...

i removed it, minimal change. ill note that current battery is 7.4 2S lipo with 250 mAh 20C . switching to a 450 mAh 80C reduced the motors speed quite noticeably but they still turn off at the same microseconds write. this must mean something but i don't what. anyway, ill document...

ill get right on that but before i do, would adding a switch be an issue? i never really thought about it much but for the longest time, my quad had a switch just because i thought it was convenient. i haven't thought about it when i add it at the beginning. could that be part of the issue?

thank you. im still having the same issue with these motors. now they make weird sounds. sounds like static. they also spike every now and then. it almost feels like they jump to a higher speed randomly and then dip back down to their intended speed. no change in writeup. im confused as all...

ill try that, thank you :D . you know i asked that before but i haven't got an answer, i just wondering if you happen to know. How do i drive 4 DC motors that are brushed through the arduino? i wanted to try building a really tiny quad but im not sure how to do the PDB's work for these motors...

should i do this only one time? or every start up?

i switched to a 250 mAh and 20C battery which is suppose to be weaker and the motors feel faster but they still turn off at some point. to be more exact, they turn off at around 1250 Microseconds write up.

meh, ill just get another battery with more mAh. its cheap. thank you for your help. i just want to say you guys are much more helpful an chill than other forums. i appreciate it, thank you. stay rad! :D

ok i found some people talking about C-rating and Amps and honestly, i have no clue what they are talking about. hardware is a weakness of mine and i followed a few guides to get to this build so i thought i was good to go :S. would getting a battery with higher mAh help ?

i dont know how to calibrate the ESC. when i was testing them, they seem to be syncing up on their own. not sure about that anymore. here is the schematic.

but how do i fix that? Motors ask for 2S 7.4v. it seems strange that the battery that the motors asks for is too heavy to carry. right now, they turn off before getting to that point where they can take off. also, i remember that the issue was recent. im sure that at one point in my testing a...

they are rated for 7.4 volts 2S. i would be glad to give them a 3V battery since its lighter but thats not what the specification says. oh by the way, i switched the PDB with one that has a Led on it and when i reach that point where the motors shut off, the led of the PDB starts to dim. im...

I have been having a problem with my motors. when i try to turn them on, i can increase all quad motors to about 30% or so and some of the motors would turn off. im using arduino nano. this is the battery...

thank you but it seems that i found the ultimate Board for what i need. A Nano BTE 33. Bluetooth + IMU (all three, Acc,Magn and Gyro) And as fast as the teensy. Seems like a fantastic deal. Thank you regardless :D...

too late, i already replaced it but i got a new problem for ya :)! im trying to replace the arduino with Teensy which has higher clock speed. Problem is, teensy cant take the 7.2 that the ESC is producing that the nano can handle. How do i reduce the power so that i dont burn the teesny? it...

long story short, my 4 in 1 esc burned the moment i plugged it in my 2s battery. im guessing that i connected it backwards the first time or something. either way, it seems that only the one part that seems to stop working is the ground and V that goes out for the controller. since im using...

ah i see. Im using a MPU6050 if im not mistaken. The creators of the chip provided the code to access the gyroscope/ Acc but not directly. It is suppose to spit out an accurate Angle readings of Yaw,Pitch and Roll. Not sure how to check if its accurate though. i looked into filtering...
