It is a cool design. I went through the webpage and it might appeal every EE. But does it make a business case?...I don't think so. Why would I need a scope/waveform generator in a watch? Again, talking about the power it takes, "When using the oscilloscope, the battery will last about 12 hours"...does it make sense for it to be in a form of an watch? Why not a pocket oscilloscope in the size of a phone or perhaps using the phone, with better specs & a bit bigger display, with more buttons/nobs? Would it be so difficult to carry if it comes in the size of a mobile phone?
Well, you would certainly get a longer battery life with the phone sized form factor. I would assume that you aren't going to have it in scope mode all the time though so the watch should last much longer. Then again, I don't want to have to charge my watch a couple times a week.
I can't see that many uses for a handheld CRO and signal generator, HOWEVER, there are many IT and installer folk who could use a TDR, which requires almost the same hardware. TDR's are used to send a tiny blip down a wire and look for reflections caused by breaks, joins, taps and ends of wires. It's quite easy to measure to within a few centimetres where a cable join is, for example. They can also be used for optical fibre.
This is probably a larger market for the designer than the plain old oscilloscope, as extreme portability is of concern for the installers/IT folks.
Gabriel's stuff is very cool. I have one of his older boards that I am going to build into a breadboard (when I get the time....)
As per the above posters, i wonder how useful a scope watch would really be - apart from anything else it would limit the use of the hand you were wearing it on. Maybe the strap could become a stand? The limited battery life will put a lot of people off. So maybe make a hinged cover with a solar cell on it to act as a dual-purpose charger and screen protector. or build solar cells into the strap, or sell it with a stand to sit it on overnight that acts as a charger...??
But I think Gabriel could make his money on this selling them to geeks like Max and me :-)
