but not as impressive as this..... http://www.youtube.com/watch?v=s1eNjUgaB-g And you don't even need to build hardware - just plug your soundcard into the scope....

Neat. Could one make the 4th "unused" voltage level something out of range of the display, so that the extra lines are not visible? Mark

Our expensive scopes already have time-of-day clocks. John

Some guys actually did some similar using a PC soundcard. They made a 'demo' similar to the ones often found for home computers like Commodore 64, Amiga, MSX and so on. http://www.makezine.com/blog/archive/2007/08/youscope_oscilloscope_dem.html -- Reply to nico@nctdevpuntnl (punt=.)

Can't you just tie a long rope on the oscilloscope and make a pendulum out of it? -- Many thanks, Don Lancaster voice phone: (928)428-4073 Synergetics 3860 West First Street Box 809 Thatcher, AZ 85552 rss: http://www.tinaja.com/whtnu.xml email: don@tinaja.com Please visit my GURU's LAIR web site at http://www.tinaja.com

No need for that, it orbits the sun once a year, all by itself.

Maybe I can get it to sweep exactly once per day. John

Good idea. That requires a display module, and a sensor to detect the passage of the scope. You also need some sort of power to overcome the frictional etc. losses in the pendulum. I suspect the PIC coding will be more complex. It will probably also need an accurate oscillator to detect heat, atmospheric etc. influence on the pendulum and to apply corrections. -- Chuck F (cbfalconer at maineline dot net) <http://cbfalconer.home.att.net> Try the download section. -- Posted via a free Usenet account from http://www.teranews.com

For you next project, build a device that will accept a string of characters and convert them to a voltage function of time, as in the logo for the Plessey Company: http://en.wikipedia.org/wiki/Plessey -- Joe
