Kids certainly know how to play with computers and gadgets, but few know they can build their own.
Eben Upton from the Raspberry Pi Foundation in Cambridge told the BBC: "It has been six years in the making; the number of things that had to go right for this to happen is enormous. I couldn't be more pleased."
A no frills, cheap as chips computer sold without a keyboard, monitor or casing, the Raspberry Pi will help kids learn programming skills, reversing what's deemed as a decline in tech skills being taught in schools.
The super cheap computers are so popular Raspberry Pi's website crashed. On the first day of sales, Raspberry Pi has limited quantities to one per customer. Schools will soon be able to buy in batches.
The first batch of Raspberry Pi is called Model B and features an Ethernet port and 2 USB ports.
Model A includes 256MB of RAM, but not the Ethernet or USB ports, and will go into production immediately.
