    My own RFC design recommendation

    Hi all I'm new here and I will make a rocket flight controller for apogee payload release. Can you suggest me an IMU for gyro, pressure sensor, gnss, rf communication module and microcontroller for my controller card. I want to get a high performance and don't want to have a problem with...

    Eggtimer Classic............issues

    Hey everyone, I bought and built an Eggtimer Classic as a backup to my telemetrum. I'm finally jumping in to the eggtimer (the telemetrum was pretty easy to setup) and I've had nothing but issues trying to get into the programing of this thing. What I can gather after about an hour of...

    Radio Questions for Telemetry Transmission

    Hello! I am in my university's Rocket Club and am trying to design our telemetry transmission system for our Avionics Team. We are building our own hybrid-engine rocket, and our first launch is expected to reach an apogee of approximately 500 meters. We want to send data from sensors...

    Question about igniting backup B.P. charges

    Hey all, I had a quick question, So I am intending to have a backup black powder charge for the drogue and main parachute deployments. I have two altimeters that I am going to use. The first question is: I was going to have the main altimeter (an RRC3) fire the main charges. Then have the...

    Roll Control Questions

    Hi all, hope you are well. Toying with the idea of building simple avionics that maintains the rocket's roll angle so that video capture does not spin like mad. Two questions: 1. Is this as simple as a single-axis gyro driving a servo? Or are there any major complications I am missing? 2...

    High Powered Rocketery Sensors

    Hey Avionics People ! What would you use as an IMU if your rocket undergoes 20g for a small amount of time? We are building a rocket to reach 8km's ( about 25 to 30k feets). BNO055 is a nice one but it's operation range is less then 16g for its accelerometer. I don't know if it brokes after...

    Will a broken TeleMega still light up?

    Hi all I recently got my hands on some used TeleMegas and EasyMegas. I've been testing and some of them are good, some I'm not entirely sure. I have a few TeleMegas (oddly haven't seen this problem with EasyMegas) that won't show up on AltOS, nor make any beeps on startup. They only light up...

    Flight Computer

    Hello, We will participate in a rocket competition. We will ascend to 5000 feet altitude. We want to use a commercial flight computer in our rocket. We need to communicate with the rocket and receive various data (altitude pressure-temperature etc.). With this system, we also need to activate...

    Need Help Choosing a GPS Module For my Avionics

    I'm trying to decide between choices of GPS modules for my rocket avionics computer. (This computer is just for dual deployment recovery.) First thing to note is that the rocket I'm preparing this computer for will experience 18G of acceleration. I know that consumer-level GPS modules can't...

    Avionics Bay/Sled Build Thread?......Sure!

    Hello All- I was beginning a new build of an electronics bay for a custom Mac-Performance kit I got with a little Christmas spending money. When I got about 20% into, it I had the idea of doing a build thread. I don't ever remember seeing build thread for an avionics bay. Often people (me...

    Supersonic Rocket Communications

    Hi, we are a rocketry team from TU Yildiz, Turkey. This year we are planning to compete in a 6km altitude rocketry competition, our rocket will reach supersonic speeds. Last year we made a subsonic rocket for 3km altitude that used HopeRF RFM98W 433MHz RF module (It worked fine.). We are aware...

    What to watch out for? (Rocket Flight Computer)

    Hello, thank you for your time. We are building a rocket for an upcoming rocketry contest. We want to prepare for every possible problem in the avionics department. If you could list some of the problems you can think of down below that would be much appreciated. If possible please leave links...

    Quectel L80

    Hello, thank you for paying attention. We are trying to switch to Quectel L80 GPS module from GY-NEO6MV2 for our rocket. The rocket will be a 1500m sounding rocket. GY-NEO GPS module has us worried because it doesnt easily connect to the satelites (At least in our experience so far.). Our...
