PlainDAQ can be used in a wide array industrial applications, including remote data logging and control. With the help of open-source Python scripts and firmware, you can configure PlainDAQ however you like, and its Wi-Fi capability supports a variety of remote applications.
I designed PlainDAQ, in part, to help people understand complex issues in electronics. Its ability to generate and capture waveforms can help students and hobbyists learn about the circuits they are building. As an affordable piece of multi-purpose lab equipment, PlainDAQ is the perfect addition to that first electronics lab.
In particular, I’ve found that people often struggle to understand the frequency-related aspects of analog electronics: frequency response, step response, filters, etc. To address this challenge, I designed I²C-controllable low-pass and high-pass filters that can draw power directly from PlainDAQ. Their cut-off frequencies can be set individually, and they can be cascaded to form band-pass and band-stop filters. By measuring their frequency-response and changing their cut-off frequencies, you can observe their behavior and improve your understanding of these concepts.
I also have started a project page for the filter please check:
