About 6 years ago, I purchased a meter (Fluke size) from Radio Shack that could feed a digital out via USB (serial adapter) for $69. Given that you can now purchase a bluetooth based OBDII reader for $10 on Amazon, it seems as though it's not a stretch to expect a respectable multimeter that can connect via bluetooth for well under $100.
Inexpensive is the title and yes, they are inexpensive, but that brings to mind the old saw 'you get what you pay for.' I'm not sure an osclliscope the size of a wristwatch is useful execpt in a pinch - but maybe I'm just an old codger who likes his larger screens. A lot of these gizmos seem to be small for the sake of being small, not for the sake of functionality. As someone said, 'now that you have taught the dog to talk, what does it have to say?'
I thought it was exciting when companies started offering measurement tools that connected to the iPad, but the oscilloscope watch takes this to a whole new level.
But my question is, who among you would actually connect test leads to the watch while you're wearing it? I suppose it depends on the circuit under test, but I had this humorous vision of a guy testing a high voltage switching regulator with his oscilloscope watch...while still wearing it on his wrist :)
Roger that one; even USB (2.0) sound cards can and will pitch fits with ungodly ground noise (E-MU 0404 USB. Yes, Creative Labs, after years of getting it right, bent me, sold me their "end-of-life" crap after one-year-plus of promises; Amazoo, $185). Been there: One solution is to lift the COMPUTER ground, which EE's, myself included, would rather not; two, is put'm CLOSE and ground'm all with HEAVY braid. My 'lab' of all trades is EMI-noisy so I use both, and it works for me.
Researched it 'til i'm worth << $1/day, mainly because of the market potential. May still be a huge market there as USB 3.0 has the SAME PROBLEM (480Mb/s a problem? Imagine 5Gb/s or so...) Read Ethernet does not have said ground issues necessarily, could be Firewire either; stopped right there as I simply want to do loudspeaker T/S parameters, audio spectrum analysis, DSP galore, stuff like that.
Still looking for the audio spectrum analyzer S/W; must be the best, free is a non-issue...
AI is it, ask IBM, and life is short so somebody else please solve the above. Thank you kindly.
