oscilloscope apps?

[noystoise]

does anyone here have any experience with signalscope pro?

it looks cool, but i dont know if i want to drop $75usd for it. any input?

Depends what you wanted it for i guess. The frequency response seems to be only 100Hz-8khz which makes it pretty useless for a whole lot of stuff.

i was looking at one of these the other day

I'm not sure what to make of that either

[noystoise]

good point! how did i miss that? why couldnt they just come up with a serial port adapter for the probes?

I bought an OWON digital oscilloscope a short while ago, clearance sale, it's pretty damn cool - you can change the colour of the scope an all - that's what matters more than anything else!

You can pick these apps up for free, if you're clever and do a little bit of research

But I have to say, that portable oscilloscope from Queensland, Australia is a nice little device!

There are some make your oscilloscope kits here http://www.seeedstudio.com/depot/index.php?main_page=advanced_search_result&search_in_description=1&keyword=oscilloscope

i got one of the kits and it works fine for audio stuff a little faffy to build and use but for the price GREAT, postage was quick. Ive used them twice now with no problems  cheapist ive found

Do they give accurate readings? p.s I love Seeedstudio  best place for Arduino bits and cheap-expensive sensors like Ultrasonics

well i quess so but i havent a callibrated oscillascope to check it against. its seems to give good acuracy for frequency time and shows wave shape and signal amplitude thats all i use it for.

while iam here i haveing a problem measuring current use of a circuit ive designed i have tried using a mulitimeter inline with the positive power (iam using a 9v battery to power the circuit) iam getting a reading of about 20 microamps but the battery only lasts 30mins or so have you can any current measuring tecniques

Pico scope is pretty neat. If you have the cash. The hardware interface is a bit expensive..

Maybe check ebay ?
