Karen has an idea for a project, with Felix's help to create a portable Raspberry Pi photo' booth, useful for weddings and other events. This isn't only a hardware project, it also needs the linux software to help ensure we're saving the files where we want them and even upload them to an online service! Felix takes this as an opportunity to give everyone a crash course in how to use linux on the Raspberry Pi and keep it up to date. After the design's put together, Karen talks us through her python logic to have the camera take pictures! How's your Python programming? What Pi Cam projects have you made? Or how would you have changed this one?
