turn your expensive oscilloscope into a $5 clock

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

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=.)

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
