Securely tailor your TV viewing with BBC Box and Raspberry Pi

Thanks to BBC Box, you might be able to enjoy personalised services without giving up all your data. Sean McManus reports:

One day, you could watch TV shows that are tailored to your interests, thanks to BBC Box. It pulls together personal data from different sources in a household device, and gives you control over which apps may access it.

“If we were to create a device like BBC Box and put it out there, it would allow us to create personalised services without holding personal data,” says Max Leonard.

TV shows could be edited on the device to match the user’s interests, without those interests being disclosed to the BBC. One user might see more tech news and less sport news, for example.

BBC Box was partly inspired by a change in the law that gives us all the right to reuse data that companies hold on us. “You can pull out data dumps, but it’s difficult to do anything with them unless you’re a data scientist,” explains Max. “We’re trying to create technologies to enable people to do interesting things with their data, and allow organisations to create services based on that data on your behalf.”

Building the box

BBC Box is based on Raspberry Pi 3B+, the most powerful model available when this project began. “Raspberry Pi is an amazing prototyping platform,” says Max. “Relatively powerful, inexpensive, with GPIO, and able to run a proper OS. Most importantly, it can fit inside a small box!”

That prototype box is a thing of beauty, a hexagonal tube made of cedar wood. “We created a set of principles for experience and interaction with BBC Box and themes of strength, protection, and ownership came out very strongly,” says Jasmine Cox. “We looked at shapes in nature and architecture that were evocative of these themes (beehives, castles, triangles) and played with how they could be a housing for Raspberry Pi.”

The core software for collating and managing access to data is called Databox. Alpine Linux was chosen because it’s “lightweight, speedy but most importantly secure”, in Max’s words. To get around problems making GPIO access work on Alpine Linux, an Arduino Nano is used to control the LEDs. Storage is a 64GB microSD card, and apps run inside Docker containers, which helps to isolate them from each other.

Combining data securely

The BBC has piloted two apps based on BBC Box. One collects your preferred type of TV programme from BBC iPlayer and your preferred music genre from Spotify. That unique combination of data can be used to recommend events you might like from Skiddle’s database.

Another application helps two users to plan a holiday together. It takes their individual preferences and shows them the destinations they both want to visit, with information about them brought in from government and commercial sources. The app protects user privacy, because neither user has to reveal places they’d rather not visit to the other user, or the reason why.

The team is now testing these concepts with users and exploring future technology options for BBC Box.

Every jack-o’-lantern needs a pair of animatronic eyes

If you’d like your jack-o’-lantern to stand out, a pair of animatronic eyes should do the trick. While there are numerous ways that you can go about this, few (if any) look as good as the set made by Will Cogley in the first video below.

The incredibly realistic 3D-printed eyeballs are installed into the hollowed out pumpkin using skewers as supports, and glance in all directions, along with orange eyelids that open and close for an even more human(ish) appearance. 

The second clip delves deeper into the eyeballs themselves, which come in several forms. Control is via a Wii Nunchuk-esque joystick interface, with the help of an Arduino.

Bugs Begone: Chameleon Tongue Inspires Fast-Acting Robots With Flash-Like Reflexes #Biomimicry

Extra large 1572384547 cover image 1

Via iflscience

A team of researchers from Purdue University is taking cues from nature to inspire fast-acting robotics with chameleon-like reflexes capable of grabbing and maneuvering items with astonishing speed. With stretchable polymers, they say these soft robots could inform efficiency in future robot manufacturing.

High-powered and high-speed, the robots get their power from their elastic energy, or capability to expand to various degrees in order to move quickly. Internal pneumatic channels expand with pressure to snap and grab, yet are able to release their hold on an object by contracting. It all comes from biomimicry: the hyper-elastic tendons in woodpeckers, the snapping speed of Venus flytraps, and of course the quick-firing tongues of chameleons. One of the robots is capable of expanding up to five times its own length and can catch and retrieve a live flying beetle in just 120 milliseconds. (Tell that to the fruit flies haunting your kitchen.)

Surf Window is an interactive beach diorama that displays surf conditions

While some of us live directly beside the beach, others—the vast majority, in fact—reside inland where we can’t see the waves on a day-to-day basis. As a solution to this issue, surfer-maker Luke Clifford came up with his own “Surf Window,” an interactive diorama that shows real-time surf conditions at a glance.

The Arduino Mega-controlled device pulls beach info from the Magicseaweed API, then adjusts the laser-cut wooden stage to match. Indicators include starfish that light up depending on how good the surf conditions are overall, a physical wave model that moves up and down to represent height, a rotating seagull to reveal wind direction, and more. 

Whether you’re a landlocked surfer, or just someone who wants to know more about the environment, this looks like a really interesting gadget. The build is currently wrapping up a Kickstarter campaign if you’d like to have your own!
