Discover Banana Pi, another Linux board for you to experiment with! Today we will introduce you to a board that replicates the approach of the Raspberry Pi but with increased functionalities, capable of running GNU / Linux and Android.
We are talking about Banana Pi microcomputer, based on the SoC Allwinner A20 produced by Lemaker, a Chinese company based in Shenzhen. The first point of interest is the name of the card itself. Just open the box and you immediately understand the reason for the naming. At first glance, it looks very much like a Raspberry Pi. In fact, Pi, at least in the initial intentions of the project Raspberry Pi, stood for the “vocation” of the board for those who want to learn Python programming. In fact, Banana Pi is equipped with a SoC Allwinner A20 processor, a very powerful processor (dual core, 1GHz each) with a “internal” management much more complex than the Raspberry Pi one, and therefore dedicated to applications much more demanding in terms of resources than those achievable with Raspberry Pi.

Whilst building lots of robots to fulfill a recent Kickstarter project, I had the need to program a thousand or so Arduinos, which would take forever if I were to program them all individually.
Situations like this are the perfect opportunity to work on those meta projects which can be just as much fun to build as the product itself. In this case I needed something that would: program a number of Arduinos in parallelwork without a screenlet me know if it had successfully programmed or notbe quick and easy to use Pogo pins are a great way of making a quick temporary electrical connection to a PCB so I decided on using those pretty quickly.
I used a little laser cut toggle to hold the Arduino in place. I connected up a USB to serial converter to each set of pogo pins and then plugged all of these into a USB hub. I wrote a simple piece of software in Node.js, which is great for this kind of parallel event-driven workload. Related. Build your own Google TV Using RaspberryPi, NodeJS and Socket.io.

When UK Prime Minister David Cameron gave a speech at CeBIT this year, what examples did he use to highlight tech innovation in Britain? Yes, ARM and Imagination were on his list, but he also referred to the tiny, Linux-based computer called Raspberry Pi, which has now sold over 2.5 million units. In a timely fashion, the Pi's makers, element 14, have just announced a new $33, Wolfson-powered audio card that should give the device a broader range of functions.
The add-on board fits right onto the Pi's P5 pins and carries a Wolfson audio processor that supports high-res audio up to 24-bit / 192KHz, which can be played via a direct connection to an amp over 3.5mm line-out or alternatively via a digital S/PDIF output. Audio recording, meanwhile, comes courtesy of two onboard MEMS mics (useful for things like voice control), a 3.5mm mic jack and a digital S/PDIF input.
