Notes

I just built The Cuttle so time for a quick test.

I thought I'd borrow an idea from the XYplotter project and get The Cuttle to write its name on an oscilloscope.

The Python script make_data.py is used to interpolate plotting points over the fundamental text structure. It generates the data.h used by the ScopeTag.ino sketch:

python make_data.py > data.h

When running on The Cuttle, it produces the image below. I'm using a Hantek MSO5074FG oscilloscope, and the image was captured with the following settings:

  • XY plot mode
  • 0.2s persistence
  • display as vectors
  • average over 4 samples
  • CH1/X offset by -4V
  • CH2/Y offset by 40mV
  • 570mV per grid

scope_text

The time-domain plot for the generated output is like this:
