Video: #^Fitting 3D Printed Electronics Bay in Panda
Image/photo

This is a test fitting of the interior bay prototype 3D Print for the experimental designed High Powered Rocket named Panda.

I'll make some minor modifications to conduits, battery containment, and backup circuitboard plane before final print.

Updated to include almost all conduits for wiring and cording.
Added vent slats for phone to dissipate heat.
Added circuitboard risers for backup electronics controller (side facing away from camera).
Reduced size of flat section for backup electronics controller to better match circuitboard (side facing away from camera).
Slightly increased diameter of entire object.
Printing a prototype now, the test print has everything but the vent slats.

Build volume is nice Freddy, enough to print that storm trooper helmet I made :-)

Part fits snug and ideal! I'll try to post a video when less tired.

I'll test all my wiring to make sure everything fits, make minor adjustments to the model, and then hopefully one more print for final.

I'm fairly certain this is the final revision and will be rigged and installed in the rocket.
Changes:

Battery containment moved down slightly(for switches) and widened at top (for battery connectors).
In space above battery containment, I created blocks for two heavy duty switches that will engage the flight computers.
Additional conduits created to support the switches.
Rotated and increased vertical space for backup flight computer 90 degrees as there simply wasn't enough room to fit inside enclosure the way I had it.
Adjusted angle of conduits below battery containment area due to less space.

I just won Horizon Forbidden West. I like that they added more function like swimming and flying. The game play is long, it felt longer than Horizon Zero Dawn.

Being excited about the release of Forbidden West, I replayed Zero Dawn prior, so I have both games fresh in my mind.

I will have to say that Zero Dawn has an unbeatable story line, it is just excellent. With them upgrading the graphics for the PS5, it maintains itself as a masterpiece.

Forbidden West has significantly weaker plot line. I believe they actually have much more voice over, acting, and conversation in general in Forbidden West. Also, they redesigned the entire way that skill tree progression works. I felt it cumbersome and battle never felt as clean as the first (although still insanely good).

All that said, I enjoyed Horizon Forbidden West quite a bit, good game. At some point I'll probably replay.

@Jason Cook
I just finished Dishonored 2. I love the steampunk meets magic world of those games. I also enjoy that it allows you to either kill your way to the finish line, or be completely non-lethal. I tried to not kill anyone whenever possible, so I could get the "good" ending, and it ended up being close to a 30 hour playthrough.

I just reinstalled Witcher 3. I only got into the second "zone" of the game on my first run. Going to see if I get sucked into it this time, or if it gets put back on the shelf for another day.

Jason Cook

jason@hub.inktada.com

Witcher 3 was tough for me to get into, I'd say it took me what felt like HALF the game before I started really liking it. I'd say the defining moment was the whole story with the baron unfolded.

After that, between all the new abilities and the story line with ciri, it was enjoyable enough to play again. I honestly couldn't stand his "default" girlfriend's personality - so the first play through I ended up with no one at the end (other than ciri as daughter.) The second game I ended up with Triss, and I looked up the right choice in the quest line to do so, because it was much more puppy dog love chasing than I would have done, lol (had to make one illogical choice in the quest line).

While I did read guides to assist with quest progression, I did not read the guides for "good" endings. I made the right choices at the right times I suppose. When I looked up the proper choices, I feel I was almost lucky, so I'd definitely save and backup.

I'll have to look into dishonored 2, I like the idea of non-lethal!

Did the balloon expand to bursting at the top or was a release triggered by other means?

The balloon expands larger and larger with the lack of pressure around it (98,100 is ~1% of sea level air pressure). Eventually, it expands so much that it burst.

In rare cases, it will not burst and that is called a "floater." This usually occurs when there is not enough helium so it doesn't get to high enough altitude.

That is a HUGE problem and varies depending on the time of year (especially for Florida surrounded on 3 sides with water). We had to wait for ideal conditions and ran many predictions for better insurance that we could recover.

Was there anything in the box besides the phone? I suppose maybe a main parachute? Was that a drogue chute below the balloon? What was the round thing lower on the line? A radar reflector?

Sat, 12 Feb 2022 18:24:02 -0500

Jason Cook

jason@hub.inktada.com

We had two or three cameras in there, the phone, & a GRMS radio relaying analog the GPS location from the voice in the phone. Everything was insulated to help fight the cold, but I believe at least one instrument fogged up due to the cold, which we will combat next time.

There's a single parachute attached between the balloon and the electronics box, which with the balloon pulling up, is collapsed vertically. Once popped, at high altitude your descent rate is high simply because there is not much air even though the chute fills with air.

So in this case, the drift while going fairly slowly up outweighs the drift of not having a drogue chute - so there's no point in a drogue. In addition, the lack of (much) air at these altitudes makes the descent rate fairly high until it gets to the altitude planes fly at.

Yes, the bottom round thing is a radar reflector. We also called the local airport tower filing a NOTAM #^https://en.wikipedia.org/wiki/NOTAM

Was there a sonic boom that I couldn't make out because of the wind noise?

How much of a difference does the lower starting air resistance make? That is, had this been launched from sea level, would there have been a significant reduction in final altitude above ground level?

Sun, 13 Feb 2022 12:04:12 -0500

Jason Cook

jason@hub.inktada.com

You can't hear the sonic boom because we are inside to cone. Had we been further away from the rocket as it was going up, we would have heard the boom.

Had the motor had more punch at the beginning, we would have been inside the cone and heard the boom.

Yes, if it would have launched at sea level, it would have gone about 3k less altitude. That said, there was a fair amount of wind, so it could have easily gone to over 30k had there been less wind.

It was an awesome launch.

I'm planning a two stage launch to hopefully 100+k, but I don't think it will happen this year, just too much going on now.

Marshall Sutherland

dwatney@hub.farthinghalearms.com

I had to go look up sonic booms to better understand what you mean.

A sonic boom doesn't occur the moment an object crosses the sound barrier; and neither is it heard in all directions emanating from the supersonic object. Rather the boom is a continuous effect that occurs while the object is travelling at supersonic speeds. But it affects only observers that are positioned at a point that intersects a region in the shape of a geometrical cone behind the object. As the object moves, this conical region also moves behind it and when the cone passes over the observer, they will briefly experience the boom.

I've misunderstood them all my life. It is rather counter-intuitive to the way we typically experience sound. As I'm thinking about it, it seems easier to imagine if I think about a hollow cone of light passing by me. Now I have to alter the memories of all the times I've been woken up by Space Shuttle booms to mean something different.

It's bizarre for sure, I'm not sure even with all the reading that I fully grasp it.

I only know from experience of actually hearing the boom on a launch (rapid acceleration rocket where Mach occurs very close to the ground), vs a slower take off, and not hearing the boom.

How does the output from this process compare to that of extruded plastic (and I know that is a HUGE range of materials)? Maybe a better question is, given that you now have a choice, what sort of things would you choose to print with this process?

Jason Cook

jason@hub.inktada.com

I'm still learning. There are definitely less options with resin. I've just ordered the "ABS like" resin which is no where near as strong as real ABS on a extruded printer. It's supposed to be one of the stronger+flexible resins.

With resin, it takes a long time to print because the resolution is so high, at least currently. So I see me printing detail parts with resin and printing large/strong/super strong/rubber like flexible/foodgrade/etc parts with extrusion.

My immediate need for resin will be things like high detail parts like a lens screw on cap for a camera - but in my case, not a camera but a rocket component.

Even with a high resolution nozzle on an extrusion printer, it couldn't come close to doing this. I love this printer for trickets and small stuff, that's for sure.

I'll come back and answer your question better after I have had more time and more resins.
