Rocket engine Tyche test day yesterday. We did all procedures necessary to fire (without firing) to work out the kinks in the process. Since real propellants are expensive, we substituted the combustible liquid oxygen and kerosene with relatively inert liquid nitrogen and water.

In the first picture I'm adjusting the valve actuator pressure (Muscle Pressure Manual Valve/"Muscle Man 💪"). The second picture is a head-on of our engine's injector plate. You'll notice some holes are bigger than others, that's because we did our flow math wrong (note to selves: d=2r, not 1r) and had to redrill to achieve the intended total orifice area without drastically increasing the number of holes (and as a result, adding potential failure points). Live and learn.

@redbullfuturist @sendcutsend Congratulations!

[Ari @aridor]

@redbullfuturist Absolutely delighted to hear. Welcome to the club. I'll let you know when my capstone team needs some fuel.

Consider me AI pilled. Currently using Grok Build to make a financial planner app. I'm blown away. It's 11pm. I have work tomorrow. I can't stop.

[Ari @aridor]

@redbullfuturist Wow. What was the final

[Ari @aridor]

@stefan_salaices W joke

[Ari @aridor]

@KennethCassel @stefan_salaices Please elaborate! I'm a year and a half from finishing ME undergrad. I could use guidance from someone in the field.

@SawyerMerritt Magnesium, huh. It could be that they're manufacturing this themselves and using it as a testbed for magnesium casting in prep for Optimus. Just a thought.

@TeslaZoa I saw this one in person. Looking closely there was some Garnet Red behind the mesh. Signature S.

@kchau I talked to an intern at Fremont recently. He said they get free charging at the factory and free FSD.

n=3 but this is starting to paint a picture

in all of the pillar/pole collisions we've seen the following is always true:

1. empty context / start of drive (aka fsd doesn't have memory of objects/pillars/pole entering a blindspot)

2. pillar/pole is in a camera blindspot

in all of them it appears that the objects do exit blindspots, at least momentarily, within seconds of starting, so in theory this a solvable problem without additional memory/compaction methods for these specific cases

surely, though, there are cases though where objects will not exit a blind spot and better memory mechanisms are going to be needed as long as blindspots exist

in the meantime, i'm happy to use smart summon when not parked around any pillars

All the benefits of trains with none of the additional construction

[ApoStructura @ApoStructura]

People have been hating on cars so much that they apply the same opposition to robotaxis, even though robotaxis solve a lot of the problems that transit also solves:

-no need to drive or own a car
-cheap
-no need for parking
-safe

For all but dense city cores it’s perfect.

@TSLAFanMtl They can make more of all other components than batteries, so # of cars made is no greater than # of batteries made
