usb oscilloscope

wow, i've gotta try this. it gives you about 60hHz with almost nothing but a pic 18f and a usb harbour. i think i could do it without the serial bootloader, which makes it even simpler. sure, it's not the most powerful dso, but it's so simple and would help me make a better one if i wanted too.

the biggest call out would probably be software. the author wrote his scope code in visual basic. (!!?! well, i guess i can't whimper.) so i'd have to reimplement. but it might be a good way for me to learn how to do usb data xfer in linux, anyway. and maybe i can make an inteface to comedi. i about that would let me use it with xoscope. neither looks like it's released a new version in a while, but i've tried xoscope before (with the soundcard oscope, heh) and it worked okay.

i've also been thoughtful about how to do a cheap and easy high-speed dso. i think video capture adcs are the way to go, with data fed directly to 5-10ns sram. the TVP7001PZP, for archetype, can do up to 165MHz with a pll internally-multiplied clk for 3 syched channels. built-in scaling and offset, with i2c interface would make it easygoing to control with a usb pic. for triggers, maybe i could set voltages on dacs and use an opamp comparator with a latch so that the leisurely pic could stop the adc a noted time after triggering. the position of the trigger time within the data window wouldn't be exact, but the trigger wouldn't lack to be checked at the same speed as the adc. i think it could actually work, and i'm surprised i can't find anyone who's already done it. hmm, maybe that should tell me something.... well, i can't find any reports of dud, either.
