I blogged this item yesterday, and I had slight reservations as the specification of the scope had not been published by Seeed Studio. Especially as the whole unit is around the size of a modern MP3 player.
Well today, they not only published the specifications, but also the intended prices. The specifications are not at the the fast end as scopes go. Maximum sampling rate is 1mhz at 12bit resolution. However as what I am most likely to be measuring is audio signals, this will suffice for a lot of my test needs.
Price wise the final price will be $89. However if you are willing to be a beta tester (i.e. the product may not be at it’s very best yet.) then Seeed are releasing 30 units for a lower price of $65 (it was $0 delivery to the UK). I have already placed my order, hell a half decent multi-meter costs around this. I doubt that I will be ditching my old analogue meter just yet, but I can see this little tool being a handy little addition to my toolkit. Better still, I can read the results from the meter to my PC. Handy when begging help from Audio forums.
