    I had planned to make this project long back. Finally, it's time to implement it.
    Opamps are fun and have lots of applications. I plan to make an audio spectrum visualizer using active filters based…

    With one op-amp you can  make a 3rd order Pafnuty Cebyshev band-pass filter. One of my favorites...Alien 

    How is that for dropping a name?

    It is interesting that some filter books are now on-line:

    You have nothing to apologize for. The mistake was mine that I wanted to imagine that. On the board it is clear that all servos receive the same signal. If I had "read" the board carefully I wouldn't have…

    One thing I have been wanting to do for a long time is to make a number of simple circuits that use opamps and that can be used when we talk about modulations at school. Eg:

    • a high frequency oscillator (even 1 MHz would be enough) to generate the carrier signal,
    • an AM modulator;
    • an FM modulator;
    • an ASK modulator;
    • an FSK modulator;
    • a PWM modulator.

    Having these simple circuits would be great for getting a better understanding of the concept of modulation.

    I have an op-amp project in the works, actually it has been in the works for years, but it still isn't good enough for me.

    I have been designing electronic drum pads using piezo sensors. I have built several iterations of drum pad, signal conditioning circuit and software, but every time I make a system, I decide it needs to be better. Every time I sit down to design the next generation, I come up with a bunch of new ideas. Then I start collecting parts to build, then I sit down to do a more detailed design and often decide to completely change the design. I have built a few designs even though I have this never ending redesign cycle going on. One of the tricky areas for me is to capture the amplitude of the drum strike with low latency. I don't want a noticeable delay from when I strike to when the note gets played. Op-amps are used to condition the signal - get the amplitude to something appropriate for an A/D, do a sample-and-hold, and trigger an A/D sample. I have all the piezo sensors and a bunch of other stuff and it will eventually become a MIDI drum set.
