Collection

Slide Rules

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

Slide Rule Formatting

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).

Mechanical Calculators

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

Electronic Calculators

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