Given the tremendous interest around the Raspberry Pi, it is surprising how few people speak about the Rikomagic MK802. Similarly to the Raspberry Pi, the MK802 is a small and cheap computer based on an ARM processor. At first sight, the MK802 seems to be a bit more expensive (around 80$, instead of 30$ for the Raspberry Pi). But this price includes a tiny enclosure, a power supply, wireless networking and required cables and adapters. So, beyond the price, what can you do with it?
In most of the examples of use for our modules which are published in this blog, a USB connection with a computer is required. It's logical for USB modules, but it's constraining. Laptops, even if they are small, take up some space. And it's difficult to devote a computer for each do-it-yourself idea that goes through our heads. Let's have a look at alternatives that exist or could exist...
This week, we are making two gauges which are going to display CPU and disk usage of a machine under Linux, but we are going to make them the Yoctopuce way: two physical gauges controlled by two servomotors! As many customers have been asking whether we support ARM architectures, we are going to create this project on a "computer" which uses this architecture.
