Fabrícate un microscopio digital
Un divertido proyecto científico.
Your Hospital Laboratory
Digital microscopy systems can cost thousands of dollars but a very useful model can be assembled by using one decent compound microscope and consumer products that cost less than $150. Many hopitals and universities have retired micorscopes that can be adapted to this task. The plans found here show how to modify a commonly found microscope. Many of these scopes have been retired in favor of more modern and ergonomically-friendly scopes. But these scopes yield suprisingly high quality images for the price. An older monocular scope can be converted to a wonderful teaching tool so long as the objective lens gives a good image.
