Get a new 2mm wide chisel iron tip, use 6-/40 leaded solder and keep it clean. Those skinny conical tips are poor at conducting heat into the joint parts which leads to excessive dwell times and potential board trace failure.
What is the music you have playing at 6:46? Its like a remix version of the theme from some documentary series I remember watching in elementary school but I can't remember the name. In any case, good video. Makes me want to find the time to do something similar.

Hey, what method is used to control the servos? Do you have a tuned PID loop to angle the servos, or are you doing more complex calculations with gyro and accelerometer values to angle the servos?
@@TZeroSystems yeah I saw another comment saying you use an exponential moving average filter, is that because the IMU is imputing data faster than the PID loop is running?
Hey! I want to work as a GNC (software, mostly) engineer later on, and I don't know what Bachelor program to pick ; CS, Electrical&Electronic Eng, Mechanical Eng... ? (great videos by the way!)
I'm struggling to write software for my own flight computer. I'm just trying to get it to accurately track attitude, linear and angular acceleration, and barometric altitude for my eventual airbrake flight controller. Do you have any advice on where to start and the best approach on structuring the code, and resources ? Thank you
Rewriting the software completely? What could possibly go wrong? I had a board fail recently too (I am sure it has nothing to do with a ballistic landing) - desoldering sucks!
EMA filter so its exponential moving average. Kinda low pass for small variation but used more for financial variability but I have seen stability examples using it and decided to give it a shot!
@@TZeroSystems, yeah, chips mounted on chips. No board. One needs to locate thin die mounted on thin glass, Or, the first die mounted on thin glass substrate and the other die mounted to the top of those die.
I have a guide that is kinda like a donut and you can align the donut hole with the motor mount. Then its just a matter of moving it a few tenths of a degree at a time until things align!
Nice work, Rob! Stoked to see the next flight!
Wen flite
Software reworks are the best :)
So hecking satisfying to work on
Great work, the quality and quantity of your videos has really improved recently. gl on your next flight

Killing it dude! I need to come out and see it fly!
I need to actually fly! I'll ping you next time!
Did someone say.... SOFTWARE REWORK?!?!?!?
Great stuff man! good luck with flights :D
Wait its all software?
@@TZeroSystems always has been 😳
I find this title very relateable

What's the song for the soldering montage @ 6:56 ? I know it's some EDM remix but the core notes are pretty familiar
Eye witness remix

Hey, what method is used to control the servos? Do you have a tuned PID loop to angle the servos, or are you doing more complex calculations with gyro and accelerometer values to angle the servos?
Both kinda, the PID loops are tuned and the gyro feeds raw data to a series of filters I am using to get better orientation data
@@TZeroSystems yeah I saw another comment saying you use an exponential moving average filter, is that because the IMU is imputing data faster than the PID loop is running?
Or is it to get a better calculation by adding low weighted previous values

"flight 4 went so successfully that i decided to change absolutly everything in the flight software". Ummmmmm that makes sense right???
Make video on basics of missle how can we made it how it changes its direction
Thats illegal...ITAR will be with you shortly, please wait patiently!
@@matthewsoules7064 ITAR?
Amazing video
Can we use your TVC code for any other rocket to work without any changes?
No it has to be tuned every time
@@TZeroSystems Ohk! Thankyou for giving information 💗
Did you implement some low pass filter for imu data.
EMA filter so its exponential moving average. Kinda low pass for small variation but used more for financial variability but I have seen stability examples using it and decided to give it a shot!
I want to control the servo with IMU data but it.
Can you tell us what is the filter used and how you implemented it.
Its an exponential moving average filter
@@TZeroSystems I always hear pid and kalman filter.
Do you think they implemented exponential moving average beside them?
hey cool project bro. who can i get the arduino codes? Patreon?
Giving out stability is still a legal grey area. Hardware is on patreon but no software
Since i am so early, i want to say hi
HELLO!
Hey Siri add resin to shopping list
Teensy go BORK
Hi! I am wondering, how do I go from a teensy and breakout board sensor modules to the bare minimum microcontroller chip?
Not overnight! It has been a long process to get to something a bit more robust but the new one is going to be even more bare bones!
@@TZeroSystems, yeah, chips mounted on chips. No board. One needs to locate thin die mounted on thin glass, Or, the first die mounted on thin glass substrate and the other die mounted to the top of those die.
what did you do in the software to align the TVC mount?
I have a guide that is kinda like a donut and you can align the donut hole with the motor mount. Then its just a matter of moving it a few tenths of a degree at a time until things align!
But the Flight Software is a complete mess why not using header files ???
in my Flight Software i use them and it makes it a lot cleaner
@@pano6035 Its better but yeah I have been told that should be my next move
I can probably write that software and make it work…
But I am not for hire unless my fiancé approve the project 😂😂😂
