After obsessing like a Lotus Eater for a week, I’ve finished my newly-invented (I hope) 25 Lotus Leaves puzzle!
The open source 3D Printer files are on Thingiverse; I’ve also written a How To sheet, with instructions and challenges. I modestly ;-) hope it’s as mathematically interesting as the famous 15 Puzzle… we’ll see!
I want to learn how to use Load Sensors to continuously weigh stuff with an Arduino, so I thought it would be fun to continuously weigh our dog, Pippa, while she sleeps in her bed each night. The project is a little like Nate Seidle’s Beehive scale, but simpler.
The idea is to turn Pippa’s bed into a scale. Pippa’s in fine shape right now, but it’s always good to keep an eye on your dog’s weight, and a custom-made scale is a great way to do it.
