Camera

To make use of the Digital D43 software, you will need a webcam and a mount to hold it on your oscilloscope.

I recommend making a light tight, enclosed tube with the camera mounted at the end. Making it light tight allows you to get clearer images - no reflections from lights and objects in the room around you.

My version first used a piece of plastic sewer pipe that fit over the circular bezel of my Telequipment D43 oscilloscope. The second (current) version I had printed with a 3D printer. It works much better.

If by some freak chance you also own a D43, you can use the drawings and 3D model included in the download to print your own camera mount.

More likely, you will have to make your own to fit whatever oscilloscope you have. That's a project you will have to manage on your own.

I have written about how I made the cameras on my blog (designing a camera mount and how I made the new camera mount. You'll find all I know about making an oscilloscope camera mount in those pages.

The blog pages also mention the webcam. The Logitech C270 was a surprisingly good choice. You can adjust the focus on it once you get it out of its housing. Proper focus lets you use a shorter tube on the camera mount. If you use a camera with a fixed focus, then your tube must be as long as the shortest distance the camera can "see." That can be 30cm (12 inches) or more on a typical webcam.

This picture shows the new camera and mount on my oscilloscope. The old camera is standing there beside the oscilloscope:
