Kirk.. I was looking your post over smart phone this morning and this was the first chance I had to really look at your links in detail... Nice job on the analysis on the gecko btw.. We've been really happy with the G540 and sort of curious on what made it tick.. So... I'm pretty sure we can figure out something to buffer the voltage and amperage signal between the beagle-bone and the gecko. That's very useful to know that the frequency isn't that big of a deal. Like I side we where getting a nice signal just hooking up to the servo thread.
Charles, I'm glad you like our vintage scope...
