3D Print Files.zip

An upload of the 3D print STL file for the first waterfall diagram generated that had interesting results. This also contains an excel file with the raw data.

Final Post Selection for Upload.zip

This contains a 3 minute RAW .WAV audio recording along with the "interesting" high-pass filtered "sound" of the grid that is featured up the top in the youtube video. Also included are the results (jpg) from the matlab run. Basically, this is the last set of results obtained before I finished this project. I'd just upload everything, but there is a 50MB limit per file upload...

Hottest Day on Record.zip

This contains the images from my project log on the hottest day ever in Adelaide. Unfortunately, it's only the images as the data is way beyond the 50MB size limit. Still, it's always nice to have them collected here and not lost in the endless log list.

WaterFall Era Pics Selection.zip

Selection of some JPGs of MATLAB plots, along with two actual plots in the MATLAB figure format. I'd like to just upload everything, but the waterfall plots are making these figures huge and that's just not possible any more. From now on it'll just by JPGs.

MATLAB Scripts.zip

The MATLAB code used to acquire data. Configuration is made in "main" and "sample grabber". Realistically, don't expect it to work with different sample rates, etc. without modification. Or just don't expect it to work at all. Run everything from "main". Written in MATLAB R2017a.

Results Images.zip

This is a collection of PNGs/JPGs of results and some other things - Check these out before the other results if you just want a feel for things.

Good Result.zip

Part 3/3: This is a "good" 16 hour results grab (no weird transients). This contains both a MATLAB figure (MATLAB 2017a) and a JPG image.

Results Set 1.zip

Part 2/3: More MATLAB figures of results (MATLAB 2017a). This is more of a results dump than anything cohesive.

Grid-2-Audio.pdf

A 3D PDF of the Grid-2-Audio PCB. Start here if you want a good look at the 3D model/layout. You'll need to download this and open it with Adobe outside of your web browser (probably). - This is the only 3D model uploaded that contains the additional "CF" capacitor across the final op-amp's feedback path.

Render Collection Upload.rar

A collection of my best renders from Fusion 360, along with the Fusion 360 file itself should anyone else care to indulge. The selection is somewhat limited due to the 50MB file limit.

GerbersV3.rar

Gerber files for the design. Note that this rar can be directly uploaded to gerber viewers and previewed/manufactured. The top/bottom paste layers are not included (can be generated from the Altium files though). - Contains "CF" op-amp filter (i.e. latest).
