"It was a bit of a shock at the end of last week when we got the latest sales figures and discovered that the 2,000,000th Raspberry Pi was sold in the last week of October," it says in a blog post. "We don't know who owns it -- if you bought one between 24 and 31 October, it might be yours. It could even be the one we gave to Prince Andrew when he visited on Halloween."
The first Pis were produced in China and arrived in the UK in February 2012. Having taken a year to sell its first million, the second million have flown off the shelves in just eight months.
Over a million of those were, at Sony's factory in south Wales, making it a genuine homegrown tech success story. The Raspberry Pi Foundation started in 2008 with a view to making it much easier for young people to learn to code.
The Pi has blossomed into a whole ecosystem of apps, custom software and accessories, with the most recent new addition to the family a Kickstarted Pi monitor.and gives you a 9-inch HD screen to watch 720p video on.
Other add-ons include a £20 camera, called NOOBS, the New Out Of Box Software, to make setting up the mini computer more simple. You can buy a Raspberry Pi with 512MB of RAM and an 8GB SD card with NOOBS preinstalled for just £33.
