DIY Scanning Electron Microscope - Overview

Today, I finally produced an image with my DIY scanning electron microscope. I've spent the last few months working on this project, and am encouraged by today's success. There is still a lot of work left to do in making the image higher resolution, and eliminating sources of noise, howe

Electron Microscopy (TEM and SEM)

We've talked a lot about light microscopy, but this technique has inherent limitations in resolution and magnification. The next paradigm in microscopy that emerged in the middle of the 20th century was electron microscopy. Because electrons have much shorter wavelengths than photons, elec

An In-Depth Look at a Telequipment D52 Vacuum Tube Oscilloscope

In this episode, we take an in-depth look at a cool old oscilloscope I got my hands on – the Telequipment D52. It’s a pretty late model scope featuring dual traces, and a mixture of tubes and transistors. It’s so gorgeous inside, I couldn’t help but get a lot of beauty shots! Here’s the m
