Is "gadget" always an electronic device?

The Online Etymology Dictionary explains the origin of the word gadget as follows:

1886, gadjet (but said to date back to 1850s), sailors' slang word for any small mechanical thing or part of a ship for which they lacked, or forgot, a name; perhaps from Fr. gâchette "catchpiece of a mechanism" (15c.), dim. of gâche "staple of a lock."

This means that the word was not used for small electronic devices in the beginning. After all, it would be quite hard to find any Blackberrys, Kindles and IPods back in the 1850s...

What about the current usage of the word gadget? Is it restricted to electronic devices? Or is it still used more generically as in the original meaning of the word?

"Gadget" is not restricted to electronic devices. Many of the clever tools used for food preparation are known as "kitchen gadgets". I myself cannot live without my ice cream scoop or pineapple corer.

Google returns 3.29 million results for "kitchen gadgets" and 19.9 million results for "garden gadgets".

And of course we must pay tribute to Inspector Gadget: the cartoon icon who is "a human being with various bionic gadgets built into his body".

This chart quite curiously indicates that the word peaked around 1950 (occupying greater popularity from the 40s to the 60s), before falling out of vogue. However, more interesting is the upswing that we see after 2000.

The first high points in the chart could potentially be attributed to Kitchen and Garden gadgets, while the upswing after 2000 is perhaps more due to more widespread use of electronic gadgets.
