With the advent of streaming companies, lots of men and women are opting to forego the selection of physical media. In flip, there are now a ton of optical drives sitting unused in components bins and outdated computer systems. If you’d like some thing helpful to do with this now-out of date engineering, you can have a try out at turning 1 into a laser microscope.
This make calls for two DVD pickups. By scanning at the time horizontally and once vertically and measuring the returning gentle from the DVD laser, an impression can be produced. For this construct, the next pickup is employed to move the object alone. The entire system is controlled by an Analog Discovery 2, whilst this theory could be ported to other microcontroller platforms. Many thanks to the very fantastic laser in a DVD and the exact movements of the motors observed in the handle machinery, the photos obtained making use of this process have the probable to be a lot more in-depth than comparable visible gentle microscopes.
Whilst this is not quite scanning electron microscope territory, it is great enough to evidently impression the inner workings of a de-capped integrated circuit. One thing like this could be indispensable for reverse-engineering ICs or troubleshooting other comparably modest electronics, with resolutions greater than can commonly be obtained with obvious light microscopes. We have even seen similar builds in the previous which create microscopes like this as devoted lab devices.
