[DJI], everyone’s favorite — but very expensive — drone company just announced the Manifold — an extremely capable high performance embedded computer for the future of aerial platforms. And guess what? It runs Ubuntu.
The unit features a quad-core ARM Cortex A-15 processor with an NVIDIA Keplar-based GPU and runs Canonical’s Ubuntu OS with support for CUDA, OpenCV and ROS. The best part is it is compatible with third-party sensors allowing developers to really expand a drone’s toolkit. The benefit of having such a powerful computer on board means you can collect and analyze data in one shot, rather than relaying the raw output down to your control hub.
And because of the added processing power and the zippy GPU, drones using this device will have new artificial intelligence applications available, like machine-learning and computer vision — Yeah, drones are going to be able to recognize and track people; it’s only a matter of time.
We wonder what this will mean for FAA regulations…
Although it isn’t official, Ubuntu Core–the tiny Internet of Things version of Ubuntu–now runs on the Raspberry Pi 2. There are prebuilt binaries as well as instructions for how to roll your own, if you prefer. You can even access GPIO
Ubuntu Core abandons the old-style Debian packages, in favor of Snap, a new version of the Ubuntu phone’s Click package manager. Snap offers transactional updates. The idea is that all of these “things” on the IoT need to be updated to patch security holes or fix other issues.

Nowadays, you can get into ham radio on the cheap. A handheld radio can be had for less than $30, and licensing is cheap or free depending on where you live. However, like most hobbies, you tend to invest in better kit over time.
[Günther] just finished up building this portable ham station to meet his own requirements. It runs off 230 VAC, or a backup 12 V car battery for emergency purposes. The Yaesu FT897d transceiver can communicate on HF + 6m, 2m, and 70 cm bands.
This transceiver can be controlled using a
With the parts chosen, [Günther] picked up a standard 5 U 19″ rack, which is typically used for audio gear. This case has the advantage of being durable, portable, and makes it easy to add shelves and drawers. With an automotive fuse block for power distribution and some power supplies, the portable rig is a fully self-contained HAM station.
The Internet of Things is here in full force. The first step when adding to the Internet of Things is obvious, adding a web interface to your project. [Jaspreet] wrote in to tell us about his project that adds a web interface to his MSP430 based project, making it easy to add any project to the internet of things.
Creating a web interface can be a bit overwhelming if you have never done it before. This project makes it easy by using a dedicated computer running Linux to handle all of the web related tasks. The LaunchPad simply interfaces with the computer using USB and Python, and the computer hosts the webpage and updates it in real time using Node.js. The result is a very professional looking interface with an impressively responsive display that can control the on-board LEDs, read analog values from the integrated ADC, and stream accelerometer data. Be sure to see it in action after the break!
We could see this project being expanded to run on the Raspberry Pi with a multitude of sensors. What will you add a web interface to next? Home automation? A weather station? Let us know!

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!
The Raspberry Pi is great if you’re looking for a cheap yet powerful computer running Linux, but let’s not forget all the other ARM dev boards out there. [Adam] spent some time this weekend putting together an Ubuntu distro for his Beagleboard XM to give it the convenience of a GUI and a whole bunch of drivers to get a lot of stuff done.
The Beagleboard XM is another high power ARM dev board that is a little more capable than the Raspberry Pi. With an integrated USB hub, LVDS LCD displays, and a camera board, the Beagleboard already has a lot of peripherals that are now only promised for the Raspberry Pi. The only problem with the Beagleboard XM is the state of drivers and software; a problem [Adam] resolved by bringing Ubuntu to the Beagleboard.
[Adam]’s distro comes with all the goodies a relatively high-powered ARM dev board should have: Python, scipy, numpy, and a few cool extras such as GIMP and Chromium. He says it’s a bit faster than the stock Raspbian distro on the Raspberry Pi, so if you’re looking for the best ARM/Linux dev board for your next project, you may want to give [Adam]’s distro a try.
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.
