Wristwatch Oscilloscope Kickstarter Project
watches stopped being a sign of nerd chic a long time ago. If your wrist
has been crying out for a device that declares to the world, "I am a
hopeless technophile... and proud of it!," then this wearable o-scope-in-a-watch
might be just the fashion statement revolution you have been waiting
for. For a $99 pledge, you can receive one of the first prototype as
part of Gabriel Anzziani's
Kickstarter project (hurry - only one left as of this writing).
Per the website, "The Oscilloscope Watch has all the features of a modern
watch (time, calendar, alarm, etc...) combined with all the features
of the popular
Xprotolab (Oscilloscope, Waveform Generator, Logic Analyzer, Protocol
Sniffer, Frequency Counter). The Xprotolab has been featured in several
other online magazines, such as
Hack a Day. and
Elektor." The $60k goal has been met and exceeded.
source code allows users to customize the device for personal needs.
Attention to power consumption means about 12 hours of continuous use
per charge, or 30 days acting as an actual time-keeping device and occasional
bragging demonstrations. "The oscilloscope can't be truly wearable/portable
if not accompanied by the probes. There are a few solutions for this
problem: 1) Carry small probes in a keychain. 2) Make a wristband made
out of the probe cables. 3) Use the probes as the watch straps... A
special BNC adapter will also be designed that will plug in the 9 pin
header, this will allow [use of] standard probes." A true devotee might
consider having a storage sac surgically implanted in his/her forearm.

Here are the Oscilloscope Watch's specifications:
The Oscilloscope Watch design is based on the Xprotolab, so the
specifications will be similar. The Oscilloscope Watch User's manual
will also be similar to the Xprotolab manual, with the additional documentation
related to the watch functions.
