We’ve seen, periodically, small, colorful “Feinberger Blocks”–officially known as “jumper” blocks. We see these small engineering/circuitry devices a few times throughout Star Trek The Original Series. The first time we see them is in the episode “The Naked Time.
Folks may heard the story of how Gene Roddenberry wanted some salt shakers for “The Man Trap”–which ended up not being appropriate for use as salt shakers–so Gene asked that they be pressed into service as medical and surgical instruments for Doctor McCoy. Gene Roddenberry had this to say in the book The Making of Star Trek by Stephen E. Whitfield & Gene Roddenberry:
There is a prop we’ve seen occasionally in Star Trek The Original Series that seems to be some type of electronic device used for testing shipboard equipment. This Equipment Tester is first seen very briefly in “The Corbomite Maneuver.” Some unnamed crewmember is using it to check one of the plant-ons on one of the bulkheads in the ship’s corridors:
One prop (well, series of props) we saw from time to time throughout all three seasons of Star Trek: The Original Series was a bunch of trigger sprayers of various sizes with fluids of various “futuristic” medicinal colors. Although they seem a bit dated now, they looked fairly futuristic when trigger sprayers first came out in the early 1960s.
There is a hand tool we saw periodically starting in the second season that seems to do double-duty as both an engineering tool and a medical tool. I’m not even sure what to call this thing. It’s about the size of a wrench but its shape is something like a two-pronged fork–like a tuning fork.
One item you’ll probably instantly recognize is a small tabletop bell (and an accompanying striker/mallet) used in court martial proceedings. It is used by the officer presiding over the court to call the court to order—usually with a series of three or four double taps to the bell: (“Ding-ding!
In addition to Mister Spock’s famous “Vulcan Harp” seen a handful of times, there is another musical instrument we saw once in Star Trek:The Original Series. In the third season’s “The Way to Eden,” (episode 75)–written by Michael Richards and Arthur Heineman and directed by David Alexander–we got to see the character credited as “Girl # 1” (she was identified by name in the actual shooting script for “The Way to Eden” as “Mavig”) play some alien stringed musical instrument.
Scotty had quite a number of different tools that he would use from time to time. Often, these tools were used less as props (actually handled by actors) a
