It's a very nice ideea, making such an oscilloscope. It seems to be very usefull to on field working persons, who debug digital circuits (more and more less power consuming). It can be further improved: a few fuses could add some protection to the carring person; also some miniatural high voltage rated reed relays could help. I think it deserves a chance to be brought to consumers use. Also it seems quite a collection piece for amateurs and hobyists. Congratulations to the inventor!
Naw, every time I lift something heavy the bulging biceps on my Schwartzaneggar-type arms would break the retention band. The wrist will do fine. I'll either use a single probe for a quick test while it is on my wrist, or unlimber it to free both my hands if I need something more sustained. Chances are, I would use something like this only for quick checks, though.
No, if I had a pocket size oscilloscope I would need to remember to keep it in my pocket, and it would probably fall out when I bent down to pick up something else I dropped. No, having it on the wrist means I have it when I need it, which is never when I expect to need it.
For me, the issue of being wired up and then moving is kind of moot. I would more likely do what the video shows elsewhere and take the watch off if I am making any kind of sustained measurement. Mostly because I will want both hands free. If I do use the scope while wearing it, I would do so only for a very quick set of tests, and probably be using a probe that is not attached to the test point but simply held there.
I imagine, however, that the problem is temporary anyway. The first accessory I would expect to see come out for this watch is a wireless probe. You plug in a radio attachment to the watch's input ports, and it receives signals from the probes. So you can leave the DUT instrumented, walk away, and come back later to make a quick check without needing to move any wires. With a 200khz analog bandwidth and 8-bit resolution on the scope, this should not be too difficult to achieve.
BTW, it has now reached its funding goal, with four days left to go.
Usually, its Rednecks that are associated with the phrase "Look what I can do." Followed by a Darwin Award-winning event. Good to see that us Geeks can get in on the act, too. :)
In the end this is a false dilemma. We don't have just two choices between not using this or zorching ourselves. One could simply use a wireless interface from the probes to the watch (display). When it comes to personal safety, isolated inputs are a good thing.
Sounds like a great add-on sales opportunity, of the "did you want tires with that?" variety.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
