The Stanford paper microscopes are the cheap, analog alternative that use just a glass bead. For electronics, it makes sense to eliminate lenses and use physics to get a simpler microscope.

Also, stop dining out for the most part: such food is heavy in calories (ie unhealthy oils and cream), salt, sugar and carbs.
Fix your own food from sources you trust, eliminating many problems.
The low-end printers don't usually have repair parts and their operating costs are higher because their toner cartridges are small and relatively expensive.
This in contrast to the very large and initially-expensive laser printers: plenty of repair parts, fewer failures and cost per page is lower.
If you want the lowest TCO printer, the safest bet is a mid-high end model. For personal use, buy a used flagship laser printer 2-3 generations old.
People buy inkjet printers because their initial acquisition costs are low but they don't think about amortized cost per page.
Add some motherfucking positivity! :)
