Idea: Make persistence of vision yoyo.

This week: prototype circuit

Charlieplexe’d persistence of vision display (using attiny45):

Same code as last week (derived from asm found online).

3d print half of a yoyo, with max dimension for final circuit (thanks Tom!)

In other news this week, hall thanksgiving feast. Nyancake makes its appearance. Trickier than I thought. Sprinkles did not turn out at all (too fine featured), cake should not be too moist (add flour). Bake at ~325F for ~1.5hrs, then (when brown on “top”) pull out and invert. Let cool for ten or twenty minutes, then gently shake out. Make sure to use cooking spray as mold release!
