Collection[edit | edit source]

Slide Rules[edit | edit source]

My most expansive collection. Slide rules are easy to store, repair, and use regularly.

Slide Rule Formatting[edit | edit source]

When describing layouts of slide rules, the following standard is used:

  • scales are ordered from the top to bottom of the rule, separated by spaces
  • parentheses "()" denote scales on the slide.
  • scales placed back-to-back or on the same line are separated by a forward slash "/."
  • scales are named as written on the rule, subscripts may be used to differentiate scales for clarity.
  • ascending scales are written in black, descending scales are written in red (with the exception of Versalog cosine scales, to match the form on the rules).

None. Apr. 28, 2022 A Ukranian circular rule, the front and back scales process in opposite directions, acting as inverted scales of each other. The face of the front moves along with a needle, while the back only has the associated needle, the face being static.

Mechanical Calculators[edit | edit source]

My original obsession. Mechanical calculators take more space and effort, so I have comparatively few.

Abacus Unknown Soroban (Japanese) Dec. 25, 2018 Has a mechanical clearing mechanism, using a scissor arm to push beads back into place.

Electronic Calculators[edit | edit source]

Newer collection, I am much less comfortable repairing and interacting with them.
