@stemexplor You'll get pretty darn accurate just measuring the height of the stack and dividing by nominal sheet thickness...

@SumisuBii @Robotbeat Ok, there may be some similarities there, but it also has a big gun, and is intended to operate tactically much closer to the battlefront and still be survivable.

@Obserfessor @Robotbeat According to Grok: The A-10's 16,000 lb external payload is comparable to (or slightly below) the B-17's absolute theoretical maximum with external racks, but far exceeds the B-17's practical/typical bomb loads of 6,000–8,000 lb.

This misses the point. Clearly he can optimize the fuel cell beyond what he has now. He’s showing that all the basic parts working together. The only thing he doesn’t have is the explosive tip/proximity fuse, but that’s just another add. The FEDs may have another take on this though.

as a explosives and missile expert: this is p much a larp post from a typical overly engineering focused person doing what is actually more of a on hands mat-sci-chem project cat think he shud change his focus cus on rocket guidance is much easier than the actual underlying rocket working perfect, which isnt hard, just takes time and experience kno3-sucrose mixture is a very inefficient fuel, but despite the mixture being mid tier porpellant, cus the flame temperature, even though low (in mid 1000s C) the pressure + flow rate is high enough it will definitely chew thru the 3d printed nozzle's choke point in less than a second😹 and since the choke point of the nozel is no longer perfect circle, it will provide imperfect thrust and could start pushing the whole thing toward 1 direction consistently, but thats not even the worst part the fuel chamber also looks highly imperfect, cus from the video the fuel also is made terribly, in the video its got crumbles of fuel😹 from my experience in casting, it looks like he simply mixed while hot, then dried, then put into the case - since this isnt a binder-based propellant, the standard for kno3-sucrose would be to cast the molten mixture directly into a mold crumbles suck because they burn unevenly, and he also dosnt have a way of having the fuel to stick to his pvc pipe's interior, so the whole fuel can just start breaking off and flying around or rotate while its burning, and the whole thing dosnt seem like a perfect cylinder either which means any part of the fuel over-burning or having an instable burn, will start ripping thru the PVC pipe, and its not because he had no burn rate modifier compounds in the fuel either, the casting was just horrendous, theres so much issues and small tips left in note books of propellant manufactuerers that will never be shared publicly, but he can simply trial-error for a long time so tldr, the fuel is casted horribly and in crumbles, it will burn super unstably at unknown bun rate, a burn rate that is also not controlled across the chamber, the nozzle choke will immediately no longer be a perfect circle because it is made out of plastic and the choke will experience highly pressurized high speed hot gas flow, thus the whole thing simply wont even fly straight, no matter how much aerodynamic control the fins have 😼👍

someone built a $96 3D-PRINTED MANPADS rocket that recalculates its mid-air trajectory using a $5 sensor and piano wire its called Project Canard it integrates with distributed camera nodes to triangulate airborne targets and update flight paths in real-time it proves the barrier to advanced hardware has completely collapsed, moving precision weapons from defense labs to consumer garages the entire launcher and interceptor frame is 3D printed in PLA and runs off a standard off-the-shelf ESP32 microcontroller it even spins up a local Wi-Fi network so you can monitor live telemetry and arm the system directly from your laptop

Do you think if I put you in a helicopter you could successfully takeoff and land? No instruction. You can watch as many YouTube videos as you want before we go.

@TheDeadDistrict Very good. Needs a skirt— draping, chains or wires or something like that to protect the wheels and undercarriage.

What is it with the American refusal to have restaurants and cafes directly by the beach? Why do they have to be further inland, or at minimum separated from the beach by a road and a parking lot. Just put the parking lot *behind* the restaurant, and you have a 10x experience.

Prediction: When fighting Iran gets too painful because of oil prices or polls or whatever, Trump will claim that the current state of things, whatever it happens to be, was his goal, declare victory, and retreat.

Okay, the beginnings of a 5 year plan: 1) Track and limit social media usage. 2) Buy another house with more land and sell current one (or buy land & keep house). 3) Go solar. 4) Get serious about long term health & medical. 5) Visit parents >4x/year. 6) Launch project in space.

@Robotbeat I think the big problem with it is that the pipeline is rated for 7mbpd but the tanker terminal is only rated for ~2mbpd

@mcuban It’s a valid point, Starlink service, getting overwhelmed, but local services will also grow to balance. Economics will drive that.

Will outdoor AI use cases, particularly when we get to “world view” based AI, overwhelm 5G ? Satellite uplinks ? And make many of those use cases, unusable ? Is the bottleneck going to be bandwidth ?

@JoshYods @mcuban His point is a serious one. Robotic AI tech talking to Starlink and overwhelming the network. But I think more local infrastructure will just come into place to balance it out because cost will also go up.
