Over the past 2 years we’ve been trying to improve on our iodine clock design. We are constantly thinking of ways to improve the reliability as well as ease of use. Our first design v1.0 was wacky, our chemistry was off and the glassware was inconsistent. In v2.0, we balanced our reactions properly and rebuilt the clock to achieve ~3s accuracy. Minor design flaws in v3.0 were fixed in v3.1 which was continuously stirred and used in our last car Plastic Metals. The timing of v3.1 was ~1s, without accounting for degradation of chemicals during the day. The current clock was designed to keep some of the functions of v3.1 to the last clock but with better ease of use. Small edits were made between v4.0 and v4.1 to fix minor sizing flaws. Also it’s magenta – 3D printing is fun…
