The EE Times Community Debates the Feasibility of Wearable Instruments

Conversations That Matter on EE Times

SAN FRANCISCO, Nov. 19, 2013 /PRNewswire/ -- Pocket-sized instruments, particularly multimeters and oscilloscopes have been around for a while – but none so small that you can actually wear them. EE Times' Martin Rowe, Senior Technical Editor brings to bear a Kickstarter project by inventor, Gabriel Anzziani, who was seeking $60,000 in funding to jump start a wrist-sized oscilloscope [he met his goal]. Rowe debates the pros and cons of actually wearing your test instrument in the article, Wearable Instruments: A Safety Hazard? Join the community debate as they discuss the good, the bad and the ugly of wearing your testing device, for example, on your wrist.

"I own one of his X-Proto lab tiny scopes, which I like very much. From the video, the "watch" scope looks to share the same command set and functionality… On the one hand, I agree with some of the concerns about having your project essentially tethered to your wrist. Just because you can build something, doesn't mean you should…On the other hand, The little scope doesn't really replace a conventional desktop scope, but it's incredibly handy to have around. Also, it reminds me of the calculator watches I used to wear - but much cooler. I'm leaning toward thinking it's positive attributes outweigh the negatives."

"For me, the issue of being wired up and then moving is kind of moot. I would more likely do what the video shows 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."
