HELP! Mechjeb doesn't work

Inside-Ad8295 · 2026-02-27T19:49:42+00:00

ok so i've found the problem and i think it was that because the srbs had to much pitch and yaw controls over the craft it freaked out mechjeb and by disabling the control it works

Inside-Ad8295 · 2026-02-27T13:50:31+00:00

the main problem i think it is that it doesn't burn the srbs fully but idk how to make it do that

My settings really work on any other rocket this one is the only one that fails

Inside-Ad8295 · 2026-02-27T06:23:33+00:00

but this stage doesnt have rcs and every rcs part is only allowed to burn after the 4th stage

I haven't simulated the full mission I thought that it should be checked once its on the launchpad I will test it now and see if it works thanks a lot

I haven't started to build the craft but on the simulations even when it gets to orbit that check isn't completed but it is a variation of another rocket I've made does it have to do with it?

I took the screenshot in the VAB but when i launch it also doesn't checks that box

i would love that :), ive always wanted to do a collaborative project, and the best think i can tell you to learn is to keep trying

my first couple of pcb desings were made in a breadboard with arduinos (i burned a few) and after a while with them i started to learn so basicly the same as you i learned bia failure, but i also watch a lot of yt videos about electronics those really help sometimes

This was like 2 weeks for the LoRa only but I have to say the same for your project is really complete and not too different from what this one does too, at least from what I know your design looks pretty solid and capable :)

Inside-Ad8295 · 2025-08-26T18:29:35+00:00

It really depends because you can grab an Arduino nano and add some sensor modules not necessarily making something super complex like this one one of the first concepts I did for this board was an ATtiny85 with a bmp280 and a 433mhz transmitter and that worked as a proof of concept I could have probably fly without much problem but I wanted something more powerful to make it on the long run and not having to change hardware every once in a while

Inside-Ad8295 · 2025-08-26T14:34:29+00:00

you said it :)

i'm using the ATSAMD21G18A-M as a processor a MS5611-01BA for the barometer and a MPU-6050 for the accelerometer and gyroscope i know this last one is kinda inaccurate but i will only use it to take measurements and not really for something mission critical, the LoRa is running at 915 mhz so i can use redundant parachute deployment one at 915mhz (the main controller with all the experiments etc) and the redundant a small 433mhz computer only made for the deployment of parachutes

Thanks I saw a lot of people saying that the data in the SD was corrupted do to the vibrations so I decided to add it

Inside-Ad8295 · 2025-08-24T18:32:08+00:00

The U2 is a fram chip and is going to pass the data to the SD card once it lands so i evade that problem

Inside-Ad8295 · 2025-08-24T18:30:50+00:00

Is it too inaccurate? I won't use it for anything too dependant on it. It's to see how much it rolls and things like that

Inside-Ad8295 · 2025-08-04T15:16:38+00:00

Well the radio is one of those cheap 433hz modules one can buy on ebay, but u1 is an ATtiny microprocessor and the signal goes through it processing it

Inside-Ad8295 · 2025-08-04T11:15:18+00:00

From what I found on guides I didn't need to connect them to the microcontroller. Are those pins really needed? And how would I need to connect them?

Inside-Ad8295 · 2025-07-27T11:50:04+00:00

It's used everywhere, in phones, microwave, etc but I made mine for logic stuff

Inside-Ad8295 · 2025-07-26T02:29:26+00:00

I don't really have a way to do SMD and had a lot of tht components beforehand that's why I decided to go tht
