Building A 3D Printed Scanning Tunneling Microscope

YouTuber [MechPanda] has recreated a DIY STM hack we covered about ten years ago, updating it to be primarily 3D-printed, using modern electronics, making it much more accessible to many folks. Thi…

Low-Cost DSP For Scanning Probe Microscopy

A scanning probe microscope comes in a wide variety of flavors, they all produce a set of data points containing the measurements at each location. Usually these data points form a regular 2D grid,…

Homebrew Probe Tip Etcher Makes Amazingly Sharp Needles

There’s a simple reason why high-tech gadgets like PCs, TVs and smartphones are so cheap: they’re mass-produced. By spreading out huge engineering costs over equally huge production vol…

Characterizing Singular Atoms Using X-Ray Spectroscopy And Scanning Tunneling Microscopy

Scanning Tunneling Microscopes (STMs) are amazing tools which can manipulate singular atoms, but they cannot characterize these atoms as they act only on the outer electron shell. Meanwhile X-ray s…
