    SMD DD1 Killer

    I recently became aware of the SMD DD1 Distortion Detector and found it to be lacking in functionality and a recent encounter with the contact, Steve Meade, left me with a disgusted taste in my mouth. :stupid: Needless to say, I am planning to destroy him. With science!

    In light of this, I set out to learn how the SMD was designed. An anonymous donor sent me detailed "guts" pics...and I reverse engineered it from photos. It's a very basic design that is "sorta" well made. There is a ton of markup in the $169-priced DD1 given that it is 100% analog and made with simplistic circuits. I would be surprised if it cost them more than $35 to make each one.

    I called up a friend and we, in record time, developed a DSP meter that displays third harmonic distortion (just like the DD1) in percent from 0.5% to ~33% (square wave) at ANY frequency AND volts RMS. We're looking at doing in/out of phase and calculated wattage. All in a smaller handheld enclosure with a backlit LCD display. For a prototype, this is a killer development in record time.

    Our target price is $100. Can we do it? We think we can!

    EDIT: We decided to not just pursue a slightly better meter - but one with many more features. There are plans to make a couple different models for those that need only a few functions vs. full featured suite.

    I'm not a complete idiot. Some parts are still missing.

    Are you going to do a youtube video showing the proper way to hook it up?

    Keep me updated on this, I will help you advertise locally and on forums. Anything that knocks Steve Meade down a notch and helps good people is time well spent to me.

    Will your product show the voltage at clipping?
