Working on a (C64) handheld probe oscilloscope

Last Updated or created 2025-11-14

These will be available in my shop.

Probably a webpage with measured examples are usefull.

There is a cover for the pogo pin which holds the ground clamp

Handheld device to measure voltages and make screenshots using an application.

Control over serial

  • Select USB device to connect
  • Start a capture to screen
  • Clear (redraw probe screen)
  • Rotate screen for left/right-handed people and easy reading
  • Sample time speed in microseconds
  • 5V reading but 15 volt tolerant, due to the SID pins
  • ??? love to hear ideas

I’m currently working on streaming output.

Below, an example of screenshotting.
