LMR on an oscilloscope.
I used Chris Meighan's ScopeShapes program to drive my oscilloscope from my PC sound card.
The program was loaded with a DXF file created by Armin Müller's eleFont program.
This was a fun day!
I just realized how easy it is to make that object "spin" around its "vertical axis". All you do is turn the X-axis amplitude way up, then down again, then inverse it, then back to zero and way up again, and again.
And again. sigh. kiss
I'm surprised I didn't say that that's not how I did it. The animation was all contained inteh DXF file. This was completely hands-off!
Is my credibility at stake, here?
