Android stick mutates into a home server


Kiss that energy hungry PC you’ve been using as a home server goodbye. [Vince Loschiavo] shows us how he squeezed a remarkable amount of functionality out of an inexpensive Android stick which manages his home’s digital empire.

He started off just wanting some network attached storage. For this he grabbed an MK802 Android Stick which you can get for a song if you find the right deal. To bend it to his will he said goodbye to the Android OS, installing Ubuntu for ARM instead. The stick (which is missing its case in the image above) connects to a USB hub in host mode, but does actually draw all of its power from the hub itself. This made it possible to attach a USB to Ethernet adapter to boost the speed which would have been limited by the WiFi connection. There’s a 320 gig USB hard drive for the storage. With that much space on hand it makes sense to add streaming media service as well which is simple since it’s running Linux. The last part of his work actually turns it into an Asterisk server by way of Google Voice and a SIP phone. An impressive outcome at a bargain price to be sure!

Robot can barely move with so much hardware strapped to it


We think that [Andrej Škraba] needs to start looking for a beefier motor platform. This little robot has so much hardware strapped to it the motors can barely keep up. But with a little help it can make its way around the house, and it takes a whole lot of connectivity and computing power along for the ride.

The white stick on the top is a single-board computer. The MK802 Mini sports an A10 processor and up to a gig of ram. Just below that is a USB hub which is sitting on top of a USB battery pack. This powers the computer and gives him the ability to plug in more than one USB device. The robot chassis is from Pololu. It uses an Arduino and a motor shield for locomotion, with commands pushed to it via USB.

This setup makes programming very easy. Here [Andrej] has a keyboard and HDMI monitor plugged in to do a little work. When not coding it can be disconnected and driven over the network. He makes this happen using an Apache server on the MK802 and node.js. See a demo of the system in the clip after the break.
