Darn that kills the whole project. Any model rocket needs to hit 5g to have enough velocity off the rod. I do not want to code a Kalman filter from scratch. I have a 10 DOF Adafruit IMU board that I was thinking of using but the same argument applies. Also they're out of production which makes...

I just ran into this on Adafruit. BNO055 + BMP280 https://www.adafruit.com/product/5937 Instant Altimeter. I just ordered mine so now I dare post this. It's damn small and saves one board on a typical make your own altimeter. Won't save any money making your own. But for those who want to code...

Try a few Art Applewhite saucers or qbits all you'll risk is some card stock.

Long story short. I had a forward closure failure and fire that toasted the body tube in front of the motor mount. In the rebuild I corrected the mistake of not epoxying the shock cord retaining bolt.

And I'm half through an upscale Estes Bandit to 2.5 inch PS 2 size.

Happy dance time!! Downloading the .jar file does it. It opens and runs and on a pi 5 It's even snappy. I haven't had time to explore yet as I've got something else to do but will try it out fully later and report back. Install the Java runtime environment as per the instructions on the...

This is on a Pi 5 with 8 gb memory (Broadcom BCM2712 quad-core Arm Cortex A76 processor @ 2.4GHz) so it should have enough umph to run. Permissions issue? Wrong java version?

Ok I've installed Java 17 downloaded the latest open rocket package and tried to run the installer. I get this. I'm running the latest raspberry pi OS (debian 12 bookworm)

Any hope of running open rocket on an raspberry pi? I have tried Ubuntu on a pi 5 and the SW is not in the app store. I have it on a 2011 emachine running Ubuntu but it crawls not runs.

How much nose weight are you using?

How about the Bandit but up scaled to 24 or 29 mm motor mount. I think PS 11 size should be about right.

That is pure evil!!!!

Ah yes the Jan/Feb 1972 issue. I built one and caught the streamer on the wing on my first and only launch. Boost gliders hate me. My giant pip squeak was and is another matter all together.

Get extra igniters. The older Estes igniters with the white tips are notorious for not lighting the motors. Estes has some nice bulk packs of rockets. For a little more skilled students. BMS has a School Rocket for $5.95 per unit.

http://papermodelingman.com/ Has large paper rockets not designed for flight. You will need to add motor mounts and double thickness to stiffen them enough for flight. Nose weight etc also

Turning the camera off will wipe the pictures / videos. There is no flash memory in this camera the pictures are stored in RAM. Also you may need to be running Win XP to run the software.The instructions are available on Estes's web site.
