Suitable for ages 7 to 11. Two young coders meet an amateur photographer who uses a helium balloon to carry a Raspberry Pi computer, webcam and radio transmitter high enough to take pictures of the curve of the Earth.

Two young coders and science presenter Minna Kane meet an amateur photographer who uses a helium balloon to carry a Raspberry Pi computer, webcam and radio transmitter high enough to take pictures of the curve of the Earth. Dave holds the world record for the highest photograph ever taken by an amateur, and shows the children how he’s programmed a tiny very basic Raspberry Pi computer to tell the webcam when to take photos, and the transmitter to send them back to Earth.
They help him pack the hardware into a box with a GPS tracker, and attach it to a helium balloon that will carry the camera above the clouds. He explains how the resolution of the pictures affects the amount of data the transmitter can send back, so he uses a lower resolution to get the pictures back quickly.
We see the looped code that tells the camera to take a photo every 30 seconds, the transmitter to send the image, and the GPS tracker to keep updating the location. The program tells Dave when the balloon has burst, and the young coders help direct him to the field where his hardware has landed, using the GPS tracker.
This clip is from the BBC series Cracking the Code. Minna Kane and her team of young coders find out all about the exciting world of computer programming in these films made for primary-age children. In Cracking the Code, they meet the visual effects artists working on Dr Who, play football with robots, test out a Formula One racing simulator and meet a man who has sent his computer into space. Back in the classroom, they learn how to write their own code and make their own games.

Teaching Computing or Computer Science?
KS2: This could be used as an illustration of designing and writing programs to accomplish specific goals. It is also a good example of working with various forms of input and output.
This clip will be relevant for teaching Computing at KS2 in England, Wales and Northern Ireland and Computing Science and ICT at Second Level in Scotland.
