The quest to measure tiny and enormous values of common physics variables continues; here, the Zeeman effect and NMR techniques are used to create a sub-picotesla magnetometer at a nitrogen-vacancy defect site in a diamond lattice.
If you think open source means unrestricted use, you need to take another look at licensing.
Designers of embedded systems need to test and troubleshoot designs by looking at both digital and analog signals, and the analog representations of digital signals. ESC Boston is the place to see mixed-signal oscilloscopes in action.
A home that generates more power than it uses sounds like a winning prospect -- but without the big grid behind it as backup, it may just be an expensive exercise in presumed virtue.
With much legacy equipment existing with older protocols and requiring diverse real-time needs, the Industrial IoT will not soon, if ever, use a single data-connectivity standard.
