I'm 8 years late but hey...

I have one in the making. Still waiting for the parts to arrive. This one is 100% analog. No microcontrollers or programming needed like the ones I've seen on the net.

Build your own RTA!

You can save a bit as you do not need a full wave rectifier. The filter leaves pretty much a sine wave so there is virtually no difference in positive or negative peaks.

I already had the boards made. It's arriving next week. There is an extra op amp so I made it full wave rather than leave it unconnected.

Very nice Quan. Would be nice if you could make these of others

I would be in for one even if it was just a kit. Whats the $$ look like for just parts?

parts alone (incl PCB's) is in the $330 range. I had some of the parts in stock though so I spent less. I'll be posting more pics once the chassis is completed.

I don't think I want to go through a project like this again. once is enough

RTA is finished.

I just have to add window tint to the display for contrast.

Here's the finished product after adding the window tint to the display...
