I planned to build 'PC Based CRO'. But it can be done with DMM circuitry, due to it's sampling disadvantage, i.e it sampling rate too low, it is not suitable for CRO (by Nyquist Theorem).
I googled for "PC Based CRO", most of the projects use the sound card as the cheap ADC.It's frequency range is limited to AF band. I'm now collecting information on fast ADC's, for the project.
After learning the circuitry and working of ADC's and its practical implementation, Project will continue. I'm currently working on Arduino. So I'll try to incorporate it to my project. I'm preparing a Tutorial Series on Arduino for Robotics Beginners.
