How many decades would it take to recreate a PMS152E alone from absolute scratch

Obviously the PMS doesn’t have to be the ultra small size it can be made in today. Photolithography would GENUINELY be nearly impossible while doing it without would only be slightly impossible.

As for absolute scratch, I mean NOTHING. Similar to The Toaster Project where I mine everything, create every single machine necessary for every single step of the way, create my own shelter, etc. Just the silicone purification process will take a few years by itself, not to mention literally everything else.

I have a few decades to spare yk lookin for some options

Just for a thought experiment. Or is it?

Will this linear actuator design work? I’ve never used them before

So I want to perform a material characterization study on a material where I need to put it under pressure. I’m in high school and don’t have a mentor or time to ask for access to university labs so I want to make something that can help me get data for cheap.

I’m trying to make a linear actuator design and physically build all the parts myself (except for the motor and leadscrew system obviously) but I don’t extensively know how these types of things work. If I was to build something like this (pictures) would there be any significant issues?

The cylinder (of which I don’t know what material to make out of) protruding out from the side would be directly connected to the sliding block part of my linear actuator so it pushes that down onto my material. I’m going to be pushing with 50lbs ish max so I’m making the majority of this out of wood.

Any tips on making sure it doesn’t get worn out by some slight imperfection over the thousands of trials I’m going to need it for? And also any tips to make it work if something is seriously wrong 😭 And lastly any other tips about doing research studies like this without lab access or a significant mentor would be greatly appreciated.

Which score to send??

I’m an engineering student and don’t know which score to send for top engineering universities (or if I should retake to improve scored more). My SAT was a 1500 (790 Math and 710 Reading) and my ACT was a 33 (36 Math, 35 Science, 34 English, 30 Reading). Do they care that much about my english sections??

So I have my list of colleges that I want to apply to. There’s 25… I maxed out the 20 on Common App and the other 5 are on different portals. I really want to go to a prestigious school but my application is somewhat weak (for reaches, as I’m an exceptional student relative to my school but average for prestigious colleges and my ECs are lacking, which I’m working on). I think this might just be cope. I would attend any of these schools if I had to. Reaches are my top priority though obviously.

Electrical engineering major. This is the list, of 4 safeties, 5 low targets, 5 high targets, and 11 reaches in order.
ASU, OSU (Ohio), UCinci, CSULB

Purdue, UCF, Virginia Tech, SJSU, SDSU

Georgia Tech, UT Austin, UFlorida, UIUC, Cal Poly SLO

Caltech, HMudd, Princeton, Rice, Stanford, UPenn, USC, Vanderbilt, UMich, MIT, Cornell
