New automatic parachute system, for a water rocket

Hello!

After the previous successful but heavy automatic parachute system*

*(If you didn't see the previous article please visit it here, as it has all the explanations about the electronics and way of working. All improvements are based on that one)

here we have the new version of the water rocket, with all the secrets and improvements on:

• the launchpad, to avoid pressure leakage.
• The fins for a more straight flight.
• The automatic parachute system, more reliable and lighter.
• The navigation software, for a more accurate detection of launch, apogee, and data storage in the Arduino EEPROM.

In this video we'll see this and other interesting details: Automatic parachute for a water rocket.

In previous videos we saw takes from the rocket, also other building details:
