Converts online MathML coded string to/from plain text string.
WinDipoles is a free passive filter simulator that enables the design, analysis, optimization, and visualization of circuits through an intuitive graphical interface. Graphs are updated instantly as component values change, providing real-time feedback. Multiple networks can be compared by overlaying their responses on a single plot.
Runs current macro in all Word documents located in the same folder.
This is my classic Polynomials And Scientific Calculator. It can perform a wide range of operations, including polynomial arithmetic (+, -, *, /), root finding, as well as logarithmic, trigonometric, and exponential functions. You can also define custom functions and work within the realm of real or complex numbers. The calculator includes built-in constants like 'π' and 'e', and supports binary, octal, and hexadecimal inputs by using the prefixes &b, &o, and &h, respectively.
Additional features include calculus operations such as derivatives, integrals, and Lagrange interpolation, as well as matrix operations or solving of systems of equations and differential equations. For guidance, you can refer to examples or view intermediate steps when available.
The Like operator in VB.NET is widely used for pattern matching in strings.
However, it has some inconsistencies, especially when handling diacritics and string expansion. LikeOperatorB, a revised version of the LikeString operator, is optimized for better performance and improved string comparison accuracy.

Thank you to all, for your confidence and support.
The official tinySA firmware executes .CMD scripts asynchronously. This means that sequences such as 'start sweep → wait → save image' may not always work reliably. The TEST7.2 XJ firmware below is an experimental build that provides fully synchronous .CMD execution, including the ability to save .CMD files directly on the tinySA. It also supports transferring files between the tinySA and the PC via USB. This is not an official tinySA firmware and is provided without any guarantee.
Windows desktop application for the SYSJOINT SV4401A and compatible USB Vector Network Analyzers (tested with nanoVNA-H).
Other VNAs using the same USB serial-command protocol may also work, although they have not been fully tested.
As of now, WinVNA has been downloaded 330 times.
Thank you for your confidence and support.
Android tablet application for nanoVNA and compatible USB Vector Network Analyzers (tested with nanoVNA-H and tinySA models).
Target platform: Android tablets with USB host support (OTG).
Note: Your tablet must be USB OTG-capable (host mode). To connect the analyzer, you'll typically need an OTG USB cable/adapter so the tablet acts as the USB host.
As of now, VnaSaViewer has been downloaded 80 times.
