Use a magnifying glass in combination with your microscope for even larger magnification. After that, use PVC pipe to make a vertical stand about 0.5 inches tall, and attach it to a square piece of plywood. I actually saw these microscopes being made by Girl Guides at a recent event my 7 year old attended. If the sample is soft, a "squash slide" may be made by. thank you so much sir...your commt wil help me to make this project improve...i'm beginner here nd its my first instructable... Super , im glad I can help.. Whatever you do , dont forget , enjoy it! Awesome idea and instructable, one of my big pet peeves is contrasting data, please make your WEBCAM: Cost the same as the one you put in the writing!

She has taught science courses at the high school, college, and graduate levels.
i saw some one who just copied you! )The other part is the lens which receives the picture from the front side and the makes it very small at the other side so that it can be projected at the CMOS sensor. Acrylic sheet were used to make upper window of the light box. this is the link:https://www.instructables.com/id/HOW-TO-TURN-ANY-WEBCAM-INTO-A-HIGH-POWER-MICROSCOP/.

Ohm's law states that the Induced current through a conductor between two points is directly proportional to the Electromotive force across the two points, and is inversely proportional to the Resistance. How to Stain Slides. 1) Assuming that this is indeed USB bus powered , how many milliamps are you pulling from the bus powering the camera and the LEDs ?
