Harry Potter fans create a fully-functioning smart wand

In the Harry Potter series, a Muggle is a person who lacks any sort of magical ability. Growing up reading these books, one can only imagine what it would be like to cast spells using a wand. Well, wonder no more as a group of NYC Muggles decided to build their own smart wand that can ‘magically’ control devices over Wi-Fi.

The 3D-printed wand is equipped with a voice recognition module that lets users cast spells of their own with a flick of the wrist, like ordering takeout from delivery.com, turning the lights on and off, as well as playing and silencing music.

Other components include (what appears to be) a MKR1000 board, a LiPo battery, a PowerBoost, a microphone, a switch, and a vibrating motor that indicates when a command is recognized.

Those wishing to buy one are out of luck, as the creators reveal this was merely a fan-made project to celebrate the Harry Potter prequel Fantastic Beasts and Where to Find Them.”  You can read more about the Muggle Wand here! 

Harry Potter location clock spies on your smart phone

The location clock found in the Harry Potter books makes for a really fun hack. Of course there’s no magic involved, just a set of hardware to monitor your phone’s GPS and a clock face to display it.

[Alastair Barber] finished building the clock at the end of last year as a Christmas gift. The display seen above uses an old mantelpiece clock to give it a finished look. He replace the clock face with a print out of the various locations known to the system and added a servo motor to drive the single hand. His hardware choices were based on what he already had on hand and what could be acquired cheaply. The an all-in-one package combines a Raspberry Pi board with a USB broadband modem to ensure that it has a persistent network connection (we’ve seen this done using WiFi in the past). The RPi checks a cellphone’s GPS data, compares it to a list of common places, then pushes commands to the Arduino which controls the clock hand’s servo motor. It’s a roundabout way of doing things but we imagine everything will get reused when the novelty of the gift wears off.
