    Help to measure 10K sub amplifier voltage output with 20:1 voltage divider and envelope follower circuit fed into an arduino

    I've made some robots with arduino, I'm not all that electronics savy. Learning as I go. From my Google searching and seeing what others have done, I am seeing if there is an easy circuit to measure the output power of a car stereo amplifier. I know i will need a circuit to find...

    Help to measure 10K sub amplifier voltage output with 20:1 voltage divider and envelope follower circuit fed into an arduino

    This is out of falstad. On the first opamp used as a regulator, there is some weird ripple (yellow) diode feedback? and the voltage follower circuit is not dropping fast enough. I'm not sure how to calculate the RC network for faster drop when I want the circuit to function for 20Hz-120Hz.

    Help to measure 10K sub amplifier voltage output with 20:1 voltage divider and envelope follower circuit fed into an arduino

    This is what I put together so far. I can't figure out how to get the model to work in the circuit lab.

    Help to measure 10K sub amplifier voltage output with 20:1 voltage divider and envelope follower circuit fed into an arduino

    Subwoofers usually run 20Hz-120Hz and the minimum voltage voltage can be in the 2-5 volt range. 5 volts feeding a 1 ohm load would be only 25 watts. I have one amplifier that outputs max at 45VAC (2000 watts at 1ohm) and another that outputs max at 100VAC (10000 watts at 1 ohm)

    Help to measure 10K sub amplifier voltage output with 20:1 voltage divider and envelope follower circuit fed into an arduino

    Bass Head garage came out with a audio watt meter that is capable of measuring up to 20K watt output from a car stereo monoblock subwoofer amplifier. I believe they are just using a diode to protect the arduino and a voltage divider circuit with some monkey business in the code to filter out an...
