The IKEA DRÖMSYN is a wall mounted cloud night light that’s perfect for a kid’s room. For $10 USD, it’s just begging for somebody to cram some electronics in there and make it do something cool.

We’re familiar with cell balancing and the need for protection circuitry, and we understand the intricacies of the various serial and parallel configurations. It’s still a process that can be daunting for the first-time pack-builder though, because the other thing that most of […]
Wyze are a company that produces a variety of home automation products. Their Wyze Sense package is a system of contact and PIR home security sensors, that piggy backs off their Wyze Cam product. In the interests of being able to use this hardware outside the prescribed corporate ecosystem, [Xuan Xing] got down to hacking. […]
[Benjamin Grosser] had a simple question: “What does Mark Zuckerberg think about?” The resulting art project is named ORDER OF MAGNITUDE and to create it he researched archives of every public utterance the founder and CEO of the world’s largest social media network has made, going as far back as 2004.
