HOW TO Water-cool your PC
Two parts water, one part coolant, and one part guts are all it takes to water-cool your PC. It may seem a little extreme for a garden-variety desktop, but if your CPU runs hot or you’ve overclocked parts of your system, nothing beats the cooling power of classic H2O. Water conducts heat far better than air, and you don’t have to be a turbogeek to perform the conversion. Modern kits make installation little more challenging than swapping a fan or a heat sink.

It is for only a personal toy reduced its size less than one fifth compared to typical line following robots, not in formura. 
Nice hack for duping slides- I started this because I have about 2000 35mm slides and nearly that many color negatives I’d like to convert to digital images, and many of them are 30 years old or more and starting to deteriorate. My first attempt involved purchasing a slide scanner from the-store-that-must-not-be-named, but it took like 3 to 4 minutes to prescan and then scan to file, and then it usually botched the exposure or the color balance.
