    Building an LC Meter with a Franklin OscillatorAlthough it dates back to the early days of the Marconi Company in the 1920s, the Franklin oscillator has remained a relatively obscure circuit, its memory mostly kept alive by ham radio operators who prize its high stability at higher frequencies. At the core of the circuit is an LC tank circuit, a fact which [nobcha] used to build quite a precise LC meter.The meter is built around two parts: the Franklin oscillator, which resonates at a frequency defined by its inductance and capacitance, and an Arduino which counts the frequency of the signal. In operation, the Arduino measures the frequency of the original LC circuit, then measures again after another element (capacitor or inductor) has been added to the circuit. By measuring how much the resonant frequency changes, it’s possible to determine the value of the new element.Before operation, the meter must be calibrated with a known reference capacitor to determine the values of the base LC circuit. In one iteration of the design, this was done automatically using a relay, while in a later version a manual switch connects the reference capacitor. Because the meter measures frequency differences and not absolute values, it minimizes parasitic effects. In testing, it was capable of measuring inductances as low as 0.1 µH.We’ve seen a few homebrew LC meters here, some battery-powered and some rather professional.hackaday.com/2026/03/18/buildi…

    @bagder Very good state of the art report about LLM plagiarism. Yeah, that's a difficult problem.

    Homo sum, humani nihil a me alienum putoThis sentence is more than two thousand years old, and I believe it is more relevant today than ever.Human beings have always created tools to improve their condition. Their productivity. We have invented tools for agriculture, medicine, electronics, and more. Each of these techniques and technologies has solved a problem (often creating others, but that is part of the game).One thing I have never understood, however, is the desire to dehumanize ourselves. To remove from humans what is human. It almost seems as if the dream of many is to become machines. Productivity at all costs, even if it means crushing people, just to see numbers grow. Results achieved through shortcuts, even if that means losing something along the way.Alongside this, there is also a push toward total standardization, stripping away the unique traits that define us as individuals.To be human means having emotions, desires, dreams, thoughts. If we give up all of this, what is left of us?#Reflections #Life

    @markwyner Ubuntu/Kubuntu... are based on Debian and have a built-in package manager to install updates. It is a Repository manager like command line apt-get where you install updates and programs. So, package manager and repository manager are interchangeable. You add Flatpack to your repository manager as a new repository. If you are new to Linux you should look for a mature Distro with a LTS.
