I’m new to arduino and I’m using an arduino nano to make a flight logger for model rockets, I cannot add a parachute to the rocket (making my own fuel) and I was wondering if the arduino inside the rocket would break from blunt force on impact.
The rocket is about 20oz and I estimate it will fly to around 800ft.
Any help is greatly appreciated, if anyone has a project on an auto opening parachute that would be awesome too!
Thanks!
It depends - If I were you, I would use a 3D printed enclosure and screw mount the arduino to it (or hot glue it)
I'd say no. Not unless there are massive things near or afixxed to it, say a battery. The nano itself is light as a feather and would stand many many G of accelleration.
Hard to say without the terminal velocity. Impact surface matters too. Hopefully someone will have some first hand experience.
Why I responded was to mention that you might want to consider using a Pro Mini board. Same capability in a smaller size with a lower mass. No usb connector to break off and smaller parts used. It’s available in an 8 MHz 3 volt version that will run directly with a 2032 coin cell.
Hard mounting it only transmits impact forces so I’d wrap it in small bubble wrap or something similar to absorb some impact and it is likely to survive an impact with soft earth. A hard parking lot surface impact, not so sure.
Agree putting a layer of bubble wrap around it will help reduce likelihood a lot. Suspending everything in the tube with rubber bands would be even better.
Best would be to have your nano operate a parachute release.....
I have seen nose heavy rockets launched over 1000ft with failed eject charge plow into the ground so hard the cardboard tube compresses till what’s left of the nose touches the tail fin.
