Raspberry Pi, $35 computer, goes on sale in UK (VIDEO)

Raspberry Pi, a low-cost, basic computer designed to help teach children to code, went on general sale in the UK today, the BBC reported. Its retail price: just £22, or $35.

The product is billed as a PC the size of a credit card. It consists of a motherboard with only the bare essentials: memory chip, USB jacks, audio and video outs, an Ethernet port, HDMI connection, SD card slot and a power socket that allows it to be run off a cell phone charger.

It has taken a team of volunteer British developers six years to get the Raspberry Pi to market.

"The number of things that had to go right for this to happen is enormous," the executive director of the non-profit Raspberry Pi Foundation, Eben Upton, told the BBC. "I couldn't be more pleased."

The foundation has an even cheaper version of the computer, known as Model A, which comes without an Ethernet connection and just one USB port. It is going into production immediately and will retail for just $25.

Following the launch of Model B at 6:00 AM this morning, a massive influx of traffic caused at least one supplier's site to crash, ZDNet reported, while the foundation's site had to go static to cope with the demand.

"Raspberry Pi" became one of the top global topics on Twitter, alongside "iPad 3," and models quickly appeared on eBay – for a marked-up price.

The developers hope their first customers will help the Raspberry Pi evolve by writing software that can then be used on the device. Ultimately, the goal is to make the computer a standard tool in schools, Upton explains.

The computers are available to order in Europe, Asia and the US from British suppliers Premier Farnell and RS Components.
