At the Maker Faire in New York, I had the pleasure to meet electrical engineer Gabriel Anzziani. His company, Gabotronics, is dedicated to making super-small tools for makers and engineers at a reasonable price. He told me he has spent the past four years developing his products: a line of miniture and portable oscilloscopes which he dubs “the world’s smallest”. A number of these covered the entire surface of his table at the Faire, for the most part little screens with little white squiggles. What’s fascinating about these squiggles is that they can represent a live electrical signal at a very reasonable accuracy.
The Xprotolab pictured above could possibly be the smallest oscilloscope. With the additional features of a waveform generator and protocol sniffer, not to mention its $49 price tag, it makes for an enticing package for anyone looking to get there hands on some signal analysis for their small AVR projects.
