It's a circular slide rule for the playdate
Can do math! 2.32 * 2.82 = 6.54:
Accessible! Has large fonts for anyone old enough to use slide rules:
Highly configurable! Choose axes as well as fonts:
- 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
Actually, I have something else in mind, and this is a precursor. Figured I'd do this first, release the code to anyone curious, and worry about the next thing next.
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
Because slide rules are awesome. And the playdate's crank is clearly designed for controlling a circular slide rule
