MATLAB 2-byte Data Capture from Tektronix MSO64 Oscilloscope
In this post I present a 2-byte data capture script using MATLAB along with the Instrument Control Toolbox.
Short-time Fourier Transform
The STFFT technique is best suited for situations where the Fourier transform over the entire signal includes too many frequency artifacts from nonstationarities (statistical changes over time). Yet the technique also has its problems too. The 3-dimensional plot generated by STFFT is strongly affected by the windowing size used in the algorithm for example. The…

How to Use a Chip Vendor Op-Amp Model in LTSpice
I introduce an Instructable that demonstrates how to go beyond the component library supplied with LTspice by incorporating an LMV321 op-amp model from three different chip vendors to create a simple amplifier schematic as shown in the drawing. Each of these models highlight different methods available within LTspice for use with the wide variety of…
Lemon Tree Infestation and How to Cure
Ron and Shehan find fruit fly larvae and citrus spider mites on a lemon tree. Stunning video using an Amscope SM-4NTPX stereo microscope in our biophysics lab leads us to find a treatment to cure the infested lemon tree using two insecticides containing safe natural ingredients: Monterey Garden Insect Spray (active ingredient Spinosad) and Green…
Image and Logic: My Lab
Welcome to my lab website: BiophysicsLab.com. I was wondering how to start my blog here. Reading through the book by Dr. Peter Galison, “Image & Logic: A Material Culture of Microphysics,” 1997, University of Chicago Press – I found a good beginning. The author explores the changing culture of experimental microphysics as complexity of equipment…
Test PDF.js Loading Behavior
Open a PDF in Media Library Using PDF.js Shortcode Block I solved the “viewing PDF problem” by clearing history in Chrome, Safari, and Firefox on Mac and Windows when a PDF fails to load! But now with the new version 3.0.4, the browser page cache/history clearing issue may be less of a problem – Thank…
