The “solar dice” reference design kit (see https://goo.gl/YRPsFf) is a clever, easy and cheap way to experiment with low power sensors, converters and microcontrollers
Solar dice reference design sounds like a great teaching tool. Kit could be the basis of a design/application contest.
It’s a clever idea, but energy harvesting is unlikely to find application beyond certain niches – remote nodes not easily accessible to change batteries. This is microwatts and high noise that we’re talking about.
