Simple triangle-wave generators have a weakness in that the waveform of their output signal normally cannot be modified. The circuit presented here makes it possible to smoothly alter the waveform of ...

When you buy the do-it-yourself kit, it requires a little solder work, and you will get everything needed to complete the project. The packet also includes a pretty good transparent acrylic enclosure, ...

Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and ...

It’s easy to have a soft spot for “mini” yet perfectly functional versions of electronic workbench tools, like [David Johnson-Davies]’s Tiny Function Generator which uses an ATtiny85 to generate ...

When working with test equipment such as oscilloscopes and function generators, it can be useful to take a screen capture. Historically this was done with Polaroid cameras that were bolted in place, ...

Creating a mesh is the first step in a wide range of applications, including scientific computing and computer graphics. An unstructured simplex mesh requires a choice of meshpoints (vertex nodes) and ...

Anyone searching for a function generator may be interested in a new DIY Arduino project which details how you can make your very own. “A function generator is a very useful tool, especially when we ...

Some think that big innovations happen as strokes of genius: the iPod came out of the brain of Steve Jobs in a lightning bolt, gravity hit Isaac Newton on the head, a hunter gatherer in the Neolithic ...

This all-analog circuit provides three key waveforms simultaneously and at the same frequency within the audio band. It is useful for evaluating audio systems, transformers, cables, and other ...
