ESP8266 Keeps Tabs on the Kid’s Tablets

Posted on by

Assuming you have a child and it’s no longer womb-bound, there’s a fairly high chance they’ve already had some experience with the glowing beauty that is the LCD display; babies of only a few months old are often given a tablet or smartphone to keep them occupied.

[Richard Garsthagen] is one such parent. He wanted a way to monitor and control how much time his children were …read more

Ask Hackaday: What Is The Future Of Implanted Electronics?

Posted on by

Biohacking is the new frontier. In just a few years, millions of people will have implanted RFID chips under the skin between their thumb and index finger. Already, thousands of people in Sweden have chipped themselves to make their daily lives easier. With a tiny electronic implant, Swedish rail passengers can pay their train ticket, and it goes without saying how convenient opening an RFID lock is without having to pull out your wallet.

That said, embedding RFID chips under the skin has been around for decades; my thirteen-year-old cat has had a chip since he was a kitten. Despite …read more

I’m attempting to build a mechanism to prevent frauds and provide traceability of physical resources in a distributed system. The idea is straightforward: the resource travels hop-by-hop on a network and each hop is held by a… Continue reading How to secure unique identification of physical resources in a distributed system?→

Basically you get locked into a room with a couple other people and have to solve various problems and puzzles until you’ve finally made enough progress that they let you out. Which actually sounds a lot like the working conditions here at Hackaday HQ, except they occasionally slip some pizza rolls under the door for us which is nice.

Whichever side you find yourself on in one of these lighthearted …read more
