The fact that anyone has the power to make a coin is amazing having huge variety and potential but the community is so dumb its so unpredictable what coin will get traction. For example there’s one coin that’s so funny it will have you in tears laughing and another one thats a tweet saying a semi popular person on X just revealed they have a dog… Guess which one hits 20k market cap in 20 minutes. submitted by /u/Illustrious-Buddy383 [link] [Kommentare]

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. submitted by /u/bount_ [link] [Kommentare]
