Model Rocketry From The Rocket’s Point Of View

When someone writes in and says, “Hey, I strapped a camera to a rocket and took videos of it launching!” it’s really hard for us to not get suckered in. Try as we might, we just couldn’t resist taking a look at the videos [Vlad] recorded of his model rocketry “exploration”.

Inspired by our 4th of July post featuring POV videos of bottle rocket launches, he bought himself an 808 keychain camera and decided to try his hand at some high flying video. He strapped the camera to his 46” Estes rocket with a few pieces of scotch tape in an effort to keep weight down, and set off to his launch pad.

He used a Estes C6-5 engine for each launch, which he estimates took the rocket up to a height of 300 feet rather than the typical 500 feet, due to the added weight. While not particularly useful, the video is still awfully fun to watch, and perhaps it will inspire others to mount cameras on even larger, more powerful rockets.

We can only hope.

Rocket Acceleration Logger

Have you ever wondered how high or how fast a model rocket goes when you launch it? [sprite_tm] did, so he decided to build a low cost, lightweight data logger that he could fit into the nose cone of his rocket. To keep the circuit small, he built it around the popular ATtiny13 microcontroller. The microcontroller collects data from a Freescale MMA7260, a 3-axis accelerometer that he extracted from a third-party Wii nunchuck controller. After the microcontroller collects the data, it’s stored in 32K of EEPROM on a 24C256. All of this is powered by a small 3.6v Li-ion battery, which is the largest part of the circuit. If this sounds like something you’d like to make, he has detailed instructions along with the software used available on his site. While we don’t launch a lot of model rockets here, we may soon start just so that we have an excuse to build this.
