Getting started with coding has never been easier. CircuitMess brings you, Spencer. It's a DIY voice assistant that talks, lights-up, connects to the internet, and understands simple voice commands. As kids work on building Spencer, they will learn about soldering, microcomputers, electronics, LED grids, sound processing, and even coding! Spencer can tell the weather forecast, throw a joke, sing a song, show animations, set the alarm, or make corny popular culture references. This kit is complete with a build guide so you and your kid can work on it even without prior knowledge.
