There’s plenty of surprises to be had when you become a parent, and one of the first is that it’s suddenly your job to record the frequency of your infant’s various bodily functions in exacting detail. How many times did the little tyke eat, how long did they sleep, and perhaps most critically, how many […]
Have you ever thought of giving new buzz to outdated wired alarm systems or saving money while upgrading your home security? The Hornet Nest Alarm Panel, to which hacker [Patrick van Oosterwijck] contributes, does just that.

[Mattmopar] figured out how to get a white Christmas even if the weather isn’t frightful. He built a simple DIY snow making machine with a few plumbing parts, and tools you probably already have. Snowmaking machines used on the ski slopes cost tens of thousands of dollars. Even the “low-cost” home versions are $400 and […]

It’s recently been brought to our attention that the Xiaomi […]
