Rocket Avionics - Building Lumineer

I work in biomedical research. “I know more than you” is such an easy trap to step into.
Humility is hard. It stays hard.
Hubris is so appealing and easy.

I feel bad watching Joe desperately trying to hold on to his last remaining marbles while getting Lumineer ready to fly.

You might consider looking into microsd extender cables. They let you plug one end of the cable into the microsd slot, while the microsd card itself goes into the other end in a different location. Compatibility is definitely on a device by device basis, but the advantage is you could build a more secure environment for just the microsd cards, rather than having to protect the entire camera or whatever else you put the microsd card into.

Oh hey! someone else follows the same engineering process as me!

Perhaps, on a future flight, a painting with dotted lines with the words: "cut here" will be interesting.

Also you could Yeet reaction wheel “leaves” out of the body before saturation. Toss them out all 4 cardinal directions from the body. Good excuse to use frangible joints with explosives too

You should remove the 5v line going from AVA to the ESC. The 5v line is there for the ESC to provide power to an RC radio receiver (e.g., the BEC). Since AVA is already getting power from elsewhere, this isn't needed. You only need to send PWM and ground to the ESC in order to control it.

This also helps you avoid an issue where two voltage regulators fight each other on the same supply line - it's common for drones and multi-engined RC planes to remove the 5v line from all but one ESC for this reason.

If there's one team on the entire Youtube that absolutely deserves some admiration and much more followers, it's your's.

Not only because you're highly technically skilled, or that you build rockets. But because of your fantastic skill to share your learnings and your experiences in this positive and educational way. This stuff deserves to be shared with as many people as possible, especially up and coming flight engineers and rocket enthusiasts. If we all would share and learn from each others, we help the human race evolve and hopefully prosper in both the near and far future.

To not shy away from sharing your miscalculations and errors is the most important thing to help others.

Thank you to the entire team for letting us follow you and learning together.

Buzz: "Fuses, Fuses everywhere!" - Though this might have killed the PWM pin on the MCu anyway. For protection you should definitely implement some IO saving passives on AVA, if you haven't already.

I really loved the candid video parts of the prep. The excitement and suspense and drama are all completely organic and totally thrilling. And it's fun watching professionals tear their hair out and work the problem as a deadline approaches.

Besides recovering data from busted computers, you're also getting very good at explaining your mistakes in a very clear and educational manner, ripe with the humility which hindsight brings... 😉 thanks for sharing, I'm very much looking forward to your more successful launches in the future. You'll get there.

The amount you're learning (and sharing) is incredible. Honestly, this is what it's about. Thank you so much for putting in the extra effort to share all this with us.

[edisonhswaterpolo]

I’ve been waiting for something like this. Thank you for your hard work for giving us content. This is an amazing series.

I’ve recovered data from several SD cards, full size, mini and micro. Depending on if the die is damaged. SD is easier because of the serial interface. Send me some photos of the cards

I wish I was like 5-10 years younger hanging out with this dude. I love watching him work though problems.

[freddysanders]

the dramatic tension in these lumineer videos is just amazing

For rotational stabilization I would recommend to look at rollerons. They are also based on conservation of angular momentum, but produce aerodynamic forces and are much simpler. They are also proven to work sub-, trans- and supersonic. They are for example used on the AIM-9 Sidewinder air to air missile.

"From the botom of my heart: My Bad!" You are so wonderful :D

[sjowners]

You guys are clever, a joy to watch you fix these issues together and work as a team.

One thing I like about this channel is he shows his failures which is often a better learning tool then success.
