  • to run drug tests you need six figure range machine (when new), maybe 5 euro worth of plastic (spe column, eppendorfs, pipette tips), couple ml of acetonitrile and maybe 5-7 min of machine time on average. it can run 24/7 and if you find anything you can do more detailed analysis. bro’s not earning shit, he’s paying down the machines (and maintenance)

    e: no way i’m nerd-sniped this easily. you can get hplc-ms for 90ish grand, add milliq water purification system, solvent recycling system, lots of fridges, a couple of laptops and company server and various other equipment and we’re probably in 200k range, excluding lab building itself. then you’ll need, say, $5 of consumables per sample ($2 per spe cartridge), so we’re talking about $40 revenue minus material costs. wages: you’ll need something about four people to run this thing at full tilt, two lab workers, one (?) clerk, half time driver and half time it guy, if you pay everyone 15k/mo then you need to go through 100ish samples just to pay wages not counting rent utilities and debts. but you can probably run 200 per day per machine, 300 if pushing it, so the main constraint will be logistics. because most of lab is in place then adding another hplc/ms will be only 90k. 300 samples per day print 9k per day, if you can get these samples. that’s probably why he’s expanding


















  • i was thinking more like, thin external plastic shell and empty cells inside, perhaps with another thin plastic shell on inside, and internal metal shell (on plastic support?) fitting in snugly, for mechanical stability, idk 3dprinting

    keeping leads short and nonmagnetic (dramatic reduction in skin layer depth) would be a good thing because of losses, but the longest object in capacitor would be just capacitor plates, and either way in wavelength terms it’s rather small. more precisely you can model it as open transmission line stub with some weird and low impedance, but it’s so small that you don’t have to. you can also make capacitor shorter and wider, or even add more layers like how vacuum variables are made. in nesting design you can get taper effect just by making inner layers longer
