A DIY digital camera designed to teach children about how the tech it uses works has been launched in the US.
Owners of Bigshot's device need to assemble its parts in a specific sequence to make it work. An online guide explains the science behind them.
It has been developed by a US computer science professor who used funds from Google and the US Department of Defense to develop the kit.
He aims to offer an alternative to other programming-focused projects.
"It's about getting kids' hands dirty," Bigshot's creator, Prof Shree Nayar, told the BBC. "In an age when software rules I want kids to know how to build hardware.
"We describe concepts that children would normally encounter at college, but try to make them accessible even to an 8 or 10 year old.
