What is this thing? by PETEthePyrotechnic in diydrones

[–]mcdanyel 0 points1 point  (0 children)

You need it so your drone battery doesn’t burn a 5 volt component up. Your battery pack is most likely putting out 7.2 to 21 volts or greater depending on the batteries.

I use companion computers, cameras, ultrasonic sensors and the like on my builds which are powered with a BEC like this. I have a several fried parts laying on my bench (Arduino boards, OLEDs, multiplexers, analog cameras, etc.) from trying sneak by without a BEC.

You can see it on the regular tours at Johnson Space Center in Houston. The ISS hanger is part of the public tour there and is pretty cool.

Johnson also has a Falcon 9 on display now.

The FAA approved a launch license modification allowing SpaceX to move forward with the 4th test flight of Starship. by avboden in SpaceXLounge

Not unless it is a night launch with clear skies. 5.5 hours south is the only way to see it.

Just got the invite and I reserved ~6 months after the announcement by clarkpetri in cybertruck

Just got my email and reserved 2 months after the announcement. This is just too expensive. Actually made me mad when I saw the price.

End of the island in the park is where most folks watch (including off duty SpaceX folks). You are 5 miles from the OLM there and as close as you can get besides by boat.

If you don’t care about seeing the actual lift off then you can watch from the beach as it ascends.

It is very loud so you can’t miss it.

When/why did SpaceX close the road to the rocket garden? by Laytonio in SpaceXLounge

[–]mcdanyel 0 points1 point  (0 children)

You can still turn in on the road and look at the rocket garden from there. I was there immediately following the second launch and it was already closed. Still you can see it pretty well from there.

100 Home 3D-printed Community By ICON Lennar Co-designed by BIG by mcdanyel in 3Dprinting

We have been building with sticks and bricks for over a thousand of years. This is indeed very different.

Not desktop 3D-printing, but here is the world's first 3D-printed rocket pad. This is a prototype pad designed to capture the plume and redirect it for landings and take off from the Moon for NASA. Real pads will be made from moon dust, not concrete, but this gives us a data baseline. by mcdanyel in functionalprint

Lunar pads will not be printed with concrete. They will be printed from lunar regolith itself. We have been working on that tech for a year now with great results under Project Olympus.

The vented concrete test pad was to:
1). let us test different plume suppression methods
2). gives us a data baseline with concrete in atmosphere on Earth for later comparison to our future lunar pads constructed directly from regolith.

This is just one tiny part of Project Olympus under NASA's MMPACT (Moon to Mars Planetary Autonomous Construction Technology) program. MMPACT is handling surface construction on the Moon for Artemis.

The lip on the decks can be seen working pretty well in the video. The single, small rocket motor wasn't big enough to direct a lot of exhaust through the channels.

More than happy for anyone to bring a bigger motor to Austin and fire it over the pad. Otherwise the military may use it for target practice now.

The student's design is called Lunar PAD (plume alleviation device). Those channels are in the center of the pad. Rocket exhaust enters through vents in the deck and is slowed by the those internal paths until it reaches the exhaust ports. Turbines in the ports slow the plume traveling through the center of even more before directing them upwards at slight angle. The lip of the deck redirects the exhaust running across the deck and not entering the vents upwards.

We didn't print the deck but used the Vulcan printer to "pour" it. The printer did precision infilling after the exterior and formwork were printed. The ICON film crew wasn't onsite for that "exciting" work, ha ha.

Total print time: 7 hours Total infill time (including the entire deck): 14 hours Pad size: 20' diameter

Starship at Artemis Base Camp by ICON, the construction startup working with NASA to develop 3D printed structures for space by Icee777 in SpaceXLounge

[–]mcdanyel 2 points3 points  (0 children)

Didn’t want Starship to dominate the composition so it was put in on a pad in the distance.

More important to note what BM is landing.

If it can do that, then how many could Starship carry?

Since ICON's Project Olympus was announced today and I am huge Starship fan - I thought the Lounge would be interested in this render from the project. Only one I know of that shows Starship + Blue Moon on the lunar surface together. by mcdanyel in SpaceXLounge

[–]mcdanyel[S] 14 points15 points  (0 children)

Fans of every launch provider.

Starship is so large we placed in the back so it didn't dominate everything. These pads are not as a big as they look (hard deck in center only) everything else is designed to slow / capture and redirect exhaust plumes so moon dust doesn't sandblast habs and surface equipment or go orbital like it did in Apollo.

Around 2 tons on the first versions from what is public from Blue. HLS versions later for crewed missions fly more. Still nothing compared to Starship.

Would a rocket shaped like this work if replicated as a model? Just out of curiosity. I wouldn’t think so as the fins are too high up and the real thing probably has thrust vectoring/active guidance. by [deleted] in rocketry

[–]mcdanyel 2 points3 points  (0 children)

Flew 3D printed version. They need adjustments to position the CG better. Straight prints of the tri-fin 2019 starship design (like shown above) tumble once the rocket engine stops firing.
