Anything that can get the frustration out of prototyping has got to be a good idea. For a field service engineer this has to be a great tool.
For the service engineer working on something like a track signal circuit (railway), being able to confirm that the circuit wires have gone back on the correct locations would have been such a boon and saved a lot of worry.
This is good tech, I would like to see how low the cost would be for Arduino users?
I had a similar reaction till I imagined troubleshooting a circuit that I didn't quite understand. You could click on something and it would say "this is an X and it does this, test this piont for this result"
When I first saw the video I was just so-so, but then it hit me how awesome this tool would be for analyzing old circuit boards to understand the design and functions. I could easily see this type of tool as an integrated way to take a board and reconstruct the circuit schematic and generate a PCB layout to make a replacement.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
