ESC Boston 2015 Heads Up! Awesome Analog Meters

March 02, 2015

Max The Magnificent-March 02, 2015

Almost any information that is captured by a sensor or generated by an electronic or electro-mechanical system can be displayed in analog or digital fashion. A common example with which we are all accustomed is that of a household clock.

Other familiar examples are analog and digital versions of car speedometers and analog and digital implementations of multimeters. In the not-so-distant past, just about every form of electronic display was analog in nature. Over time, however, digital displays began to dominate the scene.

Generally speaking, digital displays are quicker and easier to read than their analog counterparts (note that this does not necessarily imply that digital displays are the more accurate -- that depends on how the value to be presented is captured, stored, and displayed). Having said this, in some cases, an analog display might actually be preferable, such as an analog meter reflecting the current status of a system -- with a brief glance the operator can quickly determine if the needle is in the green ("OK"), orange ("Warning"), or red ("Danger") zones, for example.

In many cases, systems using large numbers of analog meters were created in such a way that the needles in the center positions of their meters indicated an optimal state. This allowed the operators to quickly spot any indicators that were diverging from the norm.

Quite apart from anything else, the use of analog meters (and vacuum tubes, of course) can add a certain je ne sais quoi to an electronic hobby project, perhaps lending themselves to a Steampunk look-and-feel, an art deco motif, or some other style depending on how you deploy them.

All of which brings us to ESC Boston, which will take place May 6-7, 2015. There are of course, going to be a cornucopia of presentations in the regular technical track on embedded hardware, embedded software, prototyping, teardowns, tutorials, and so forth (check the master schedule for more details).

In addition to these traditional tracks, we also have The Fantastical Theatre of Engineering Innovation, which is open to all attendees (both Conference and Demo Hall passes), and which is where you'll find some of the wilder, wackier, and off-beat topics. For example, as you can see in this video, yours truly will be presenting a session titled Creating Systems with Awesome Analog Meters.

The thing is that there are lots of tricks when it comes to using analog meters in general, and there are even more tricks with regard to using antique versions acquired from Hamfests and electronic flea markets. If you want to determine the resistance of the meter's coil, for example, a multimeter is not the way to go, because you can end up vaporizing the little rascal (the coli, not the multimeter).

All will be explained in excruciating detail (LOL) in my presentation. Have you Registered for ESC Boston 2015 yet? If not, why not? All I can say is that I very much hope to see you there. I'll be easy to spot -- I'll be the one in the Hawaiian shirt running around in ever-decreasing circles shouting "Don’t Panic! Don’t Panic!" LOL
