Surely if you have seen or read the works of JK Rowling you will be familiar with the Daily Prophet, a traditional version of the classic newspaper but with magical touches. Like all objects in the world of Harry Potter, the Prophet has also had his aftershocks.
Some disastrous and others a success like the recent one created by the user Piet Rullens Jr. This functional copy of the Prophet simulates a framed newspaper where one of the news has a 7-inch LCD screen on which it displays images.
All the project is supported by a Raspberry Pi that controls both the emission of the video and the data processed by the motion sensor that it also has. The operation is simple. The Prophet's box has a motion sensor that activates the Raspberry Pi when someone approaches.
The Prophet with Hardware Libre It activates when we get close to it
Once activated, the Raspberry Pi runs a python script that activates the SBC board and plays a 5 minute video looping. Then when no one is near the frame, the video and the Raspberry Pi will turn off so that the power consumption is not as high as other devices.
The idea of this newspaper The Prophet is really good, even if it only has one page on which to display that content. In addition, the idea of using sensors is quite attractive and interesting that It can not only work with Harry Potter gadgets but also with other projects or devices in which we need to save energy or that they do certain things when we approach the device.
The Prophet was not one of my favorite gadgets in the Harry Potter saga, but without a doubt this replica built with Hardware Libre yes it is quite interesting Do not you think?
