This is a hack in the finest sense of the term. It not only allows you to capture data from an analog oscilloscope for later analysis, but provides you with a great tool if you’re posting on the Internet about your projects. [J8g8j] used an empty cashew container to add a camera mount to the front of his scope. This is possible because the bezel around the display has a groove in it. A bit of careful measuring helped him make an opening that was just right.
You can see that the red cap for the jar holds the camera and gave him a bit of trouble in the original prototype. This version has a tray where camera sits, which replaces the Velcro with didn’t hold the camera level the first time around. He’s also painted the inside of the clear plastic to reduce glare on the oscilloscope readout. Black and white images seem to come out the clearest, but it can be difficult to make out the grid lines. The addition of LEDs to help them stand out is one of the improvements we might see in the future.
