Looks a little menacing, huh? In fact, Raybaby is quite the opposite – a proper do-gooder with its silicon heart in the right place. It’s a baby sleep monitor that tracks your little one’s breathing from afar using ultrasound-like tech that promises 98% accuracy. It’ll also send you notifications when your baby shows signs of illness, alerts you when they wake up or roll over, and serves up real-time video and audio monitoring. Its cute bobbly head helped it to smash through its Kickstarter target, and it’s shamelessly jumped over to Indiegogo for further pre-orders, from US$179.
