The new Roku remote, purchased as an upgrade so I could listen to the television through earbuds, didn’t work as planned. Periodically, without warning, the sound left the earbuds and reverted to the TV speakers.
(That’s not a technical explanation. It’s just the best I can do.)
After several momentarily successful fixes–push this button, push that button, push the other button–David said my laptop might be causing interference and he would build a Faraday cage.
A what?
An enclosure to block electromagnetic fields, named after the inventor, English scientist Michael Faraday.
He constructed two, neither of which resembled the one in Wikipedia:
The working model looks like this:
When the sound continued to cut out, David investigated further and discovered the batteries were at 0%. He changed the batteries.
Believing there was more to the malfunction than maxed-out-batteries–after all, sometimes they worked and sometimes they didn’t–David suggested I continue to use the Faraday cage.
Better safe than soundless.

We visited the Faraday Museum in London in 2002–David’s choice. It was much easier than my choice, St. Paul’s Cathedral. At the Faraday, we didn’t have to walk up a mile of stairs, and I didn’t get a bad case of acrophobia plus a mild case of the fantods in the Whispering Gallery.
