A Slide Rule for the Playdate

What?

It's a circular slide rule for the playdate

How do I use it?

• Use the crank to turn the hairline
• Hold A, B when turning the crank to rotate those axes instead
• Multiple Axes supported: x, x^2, x^3, 1/x, linear, sin/cos/tan

What, Again?

PlayDate is this cute little game console that's surprisingly awesome: http://play.date

Before you kids with your new fangled "phones" and "calculators", people used slide rules to do maths: https://en.wikipedia.org/wiki/Slide_rule

But ... Why?

Because slide rules are awesome. And the playdate's crank is clearly designed for controlling a circular slide rule
