Right now I am challenging myself to make a soft circuit project every weekend and this week’s project was a coffee sleeve with LEDs and a temperature sensor from Aniomagic. It was inspired by their tutorial on ‘smart coaster’ and translated from plastic/wired to a fleece and soft version.
Above is a pic of the finished sleeve – the LEDs turn red when my drink is too hot, and green when it is ‘just right’. More pictures at my flickr account. More on the process at my project blog: Soft Circuit Saturdays.
