Hello everyone, I am thrilled to announce that we have just completed a major milestone: our measurement and analysis tools are now live, fully documented, and ready for you to use.
Over the past weeks, we rebuilt our Waveform Analyzer and Phi Calculator from the ground up. These are not toy applications — they are precision instruments designed to reveal the hidden frequency structure in any electrical signal. And today, they are yours to explore.
What can these tools do?
They take raw oscilloscope data and show you what is actually happening inside your signal. Most people see a complex waveform and think it is random noise. But our tools separate that waveform into its individual frequency components, reveal harmonic structure, measure signal quality, and show you the fractal dimension of your measurement.
I have attached four screenshots below that show you exactly what becomes visible when you use these tools on a real signal.
- Screenshot one shows the raw waveform as it appears from the oscilloscope — complex, at first glance overwhelming.
2.Screenshot two decomposes that same signal into its individual frequency peaks by using the FFT algorithm to decompose the signal and show the frequency peaks.
What looked chaotic is revealed as perfect mathematical order — a precise harmonic series.
3. Screenshot three shows the power spectral density — the energy distribution across all scales. Notice how the signal organizes itself the same way at multiple frequencies simultaneously. This is fractal character.
4.Screenshot four is the harmonic analysis table, showing you the tone character of your signal in detail — which harmonics are present, which are absent, and what that tells you about your device.
Taken together, these four views show one physical phenomenon from four different angles. This is what precision measurement looks like.
How do you use these tools?
We have created a complete FFT Beginner's Guide PDF that walks you through everything from absolute zero. If you have an oscilloscope and want to measure your prototype, this guide shows you exactly what to do. No prior knowledge required. The guide is free and available to download immediately.
The tools themselves are also completely free. You load your oscilloscope data into the tool, and you get professional-grade analysis in seconds.
Open Source and Community:
I want to be very clear about something important: these tools are released under the GPLv3 open-source license. This means anyone can use them, study them, and improve them. But if you improve them, you must share those improvements with the community under the same license. Our work belongs to everyone. It will never be privatized or commercialized. This is a commitment to science, to collaboration, and to the principle that knowledge should be free.
What happens next?
You now have everything you need to start measuring. Download the PDF guide from here of from the FFT tool page. Access the tools. Explore your own signals. Learn at your own pace.
On Saturday and Sunday, I am available to do a live demonstration showing these tools in action, if you would like a guided introduction.
But you do not need to wait for a video — everything you need to get started is available right now!
I am grateful for this community and excited to see what you discover.
The tools are live. The knowledge is open. Let's measure together.
