Very impressive Ikalogic, That looks like a good project. Your software programming of the VB side impressed me the most. Including all the features that you have, zoom, triggering etc all within VB is impressive.
i myself use PIC and AVR uC but they never required a PC software to make it look pretty. Good old HyperTerminal is what i use.
Are you a self taught software hobbyist? i would like to look into using a software package Vb or Visual C to make some cool apps.
Well Done
