Oscillographics 2011
YouTube Uploaded by BugBrand on Sep 16, 2011
"Back in 2007 I played around with an old circuit from Elektor Magazine called 'Oscillographics' [http://www.youtube.com/watch?v=mig4oDcu2qQ].
At that time I'd come across a couple of other circuits along similar lines, but it has taken a few years for me to actually get around to trying another one out. This time it is 'The Oscilloscope Graphic Artist' from the November 1975 issue of Practical Electronics, a project by Mitchell Waite - you can find the project and some more description online here: http://www.crowncity.net/ratcave/Electro/ScopeArt/ScopeArt.html
A master oscillator (simple LFO type circuit) provides synchronisation to three further simple oscillators. Each oscillator can be switched between Triangle and Square wave-form and then there are level controls to create different mixes to drive the XY mode 'scope. There are probably quite a lot of tweaks and developments that can be done to the circuitry - these initial tests use a faithful reproduction of the original project.
And, at the same time, you can hear the harmonic waveforms generated by the circuity.
By the way - this was a pretty exploratory play with the new circuit - just trying things out and seeing what is produced. Long and rambling? Yes!"
