Most of us have heard some form of the adage, “You can buy cheaper, but you’ll never pay less.” It means that cheaper products ultimately do not stand up to the needs of their superior counterparts. Hackers love to prove this aphorism wrong by applying inexpensive upgrades to inexpensive tools to fill up a feature-rich tool bag. Take [The Thought Emporium] who has upgraded an entry-level microscope into one capable of polarized and dark-field microscopy. You can also see the video after the break.
Functionally, polarized images can reveal hidden features of things like striations in crystals or stress lines in hot glue threads. Dark-field microscopy is like replacing the normally glaring white background with a black background, and we here at Hackaday approve of that décor choice. Polarizing filters sheets are not expensive and installation can be quick, depending on your scope. Adding a dark-field filter could cost as much as a dime.
Like most mods, the greatest investment will be your time. That investment will pay back immediately by familiarizing you with your tools and their workings. In the long-run, you will have a tool with greater power.
Simple mods like the light source can be valuable, but upgrades are not limited to optical scopes, an electron microscope was brought back to life with Arduino

[Pedro] had a busted laptop LCD screen on his hands, but rather than throw it out, he brainstormed what he could possibly do with what would typically be considered a worthless item. He decided to make a simple art installation using the scrapped part, so he gathered a few other supplies and got to work.
The first thing he did was pull the LCD screen from the laptop, separating the front panel from the backlight panel. He drained the liquid crystal fluid from the display, and set it inside a picture frame in place of the glass. He added spacers around the edge of the frame so that the backlight could be mounted several inches behind the LCD panel.
[Pedro] then found a few polystyrene and polycarbonate plastic items from around the house, and placed them inside the frame. As you can see in the picture above, the polarizing filter built into the LCD screen makes for some pretty cool effects.
While you could debate for hours over exactly what is art, there’s no denying that his PolFrame looks cool and is a great way to save electronics from the scrap heap. We just want to know what he did with the LC fluid he drained from the screen!
