A few months ago a friend pulled this contraption out from under the bed and said I should record it since it made a few interesting sounds. At first when I looked at it, it seemed very much like a type writer. A closer inspection revealed that the device did not have any space for paper to be inserted into it. It also did not have the “carriage return lever” that is such a prominent part of a typewriter. This device, I was told, was a calculator!!! Here are some of the “operational sounds” I’ve recorded.
The sound the calculator generated during the addition operation (Low Number Rotation – Addition), I thought, was quite similar to that of an old second world war dynamo based radio set (If you’ve watched some of Ben Burtt’s videos on how sounds for Wall-E were created, you’ll recollect that the dynamo based radio set was used to create the sound of Wall-E’s tracks).
Overall, I thought the calculator generated an interesting set of sounds – from sharp, heavy sounding “typewriter keys” to the ubiquitous “ka – ching!” of a cash register. If you want to add a few or all of the calculator sounds I’ve recorded to your library, let me know and I’ll send them to you.
Here’s a small video of the calculator being used.
