Video and Audio Streaming from A20SOM-EVB using crtmpserver

A20-SOM-EVB-2

Our A20-SOM-EVB had camera support only in Android for a long time. Now we got e-mail from Ariee Dzig who says:

I created IP Camera using your A20SOM-EVB.
Here you can find the tutorial .

 

We try this tutorial and it works great! Now we prepare new Linux images for A20-SOM-EVB which to include the hardware encoding support for the camera!

Open Fest 2014 is approaching, get ready for the Hardware Hackathon!

logo-header

This weekend is Open Fest 2014 in Sofia! We will be there with table and Hardware Hackathon. This time we will have two new boards to assembly but we will keep this as secret 🙂

Also Olimex will have lecture “Programmable Home” presenting the new boards and solutions we work on for Home Automation.

Here are some pictures of the Hardware Hackathon we did on Open Fest in 2013.

This time we will have more and different boards to choose from, and of course the Hackathon will be free (as beer, not speech 😉 ), so you can take the board you assembly with you after the Hackathon.

Looking forward to see you there!

HIWR – Open Source Robot made with A13-OLinuXino

hiwr-full

Meet Hiwr an Open Source Robot with A13-OLinuXino, A13-LCD7TS , running ROS (Robot OS). The site still have no all information about the assembly but the 3D printed components are there and the different software modules are linked to GitHub.

Good job 🙂

TuxCon 2014 Hardware and Software Hackathons 29 of June

 

Image

 

On 29.06 in Saturday from 10.00 started the Hardware Hackathon in Olimex’s training building, many people were coming and going until 16.30 oclock, about 60 FOSDEM-85 Arduino clone boards were build from kits by people who come mostly from FOSS world and have never touch soldering iron.

The results were amazing, you can see here TuxCon glasses made with FOSDEM-85 kit:

some pictures from the Hackathon are here

 

The Software Hckathon was about programming of Interractive table:

Image

The setup was: 8×8 matrix of 64 pcs RGB LEDs connected with four US-020 Ultra sonic distance sensors connected to OLIMEXINO-328 (Arduino DueMilaNove clone) then connected via USB to A10-OLinuXino-LIME with WIFI running Debian.

LIME was registered in the local WIFI and everyone could log in through SSH and to write his own code.

The project goal was to make something interesting and interactive.

Unfortunately we found bug in our Arduino code which prevented the Hackathon to complete correctly, so we decided to do as follows:

Radoslav Kolev presented his patch work to AVR dude which allow any Linux computer with GPIOs to write code to AVR processors via GPIO fs.

What we are going to do this week is to connect some of the LIME GPIOs to Arduino ICSP so Arduino could be pre-programmed by LIME.

Also we are going to setup web camera which to point to the interactive table and to open access to the LIME in the table from internet. Then we will give 1 week time to everyone who wants to develop something on this table and test his code to may do so.

We will put detailed instructions how to login, how to program the AVR and how to program the RGB/sensors, so the Hackathon will no longer be limited to local area. Anyone from anywhere in the world could participate.

To prevent problems made by the parallel login and programming we encourage the developers to enter in #olimex IRC channel and coordinate the programming and table use.

The prize for the most interesting program will be A20-OLinuXino-MICRO.

We hope the table to be ready for hacking by the end of this week!

TuxCon the FOSS Conference for Mobile and Embedded devices is less than 2 weeks away

Image

TuxCon  is a community-driven event about free and open-source software for mobile and embedded devices. The event is organized by Plovdiv’s hackerspace Hackafe and the entry is free.

Saturday, 28th of June is the day for lectures: the schedule is available at TuxCon web http://tuxcon.mobi/#schedule

During the event there are two lectures where OLinuXino Open Source Hardware Linux computers will be discussed:

Image

The first lecture is “Physical computing with Linux” in which it will be explained at a non-embedded developers level how to access all hardware resources from the Linux user space for OLinuXino like GPIOs, I2C, SPI, UARTs, the Power management – how to make your code aware of whether it runs on Battery or on Mains power supply, what is the temperature of the processor, is the battery charging or not, etc. It will also be explained how to connect sensors, how to connect steppers and servos, how to control them from Linux, how to setup a web server on OLinuXino, how to make all of the hardware resources, offered by this board, available via web interface as well as how to attach camera and do OpenCV processing, and more.

Image

The Second lecture is “Linux driver” where it will be explained how a Linux Driver is created and there will be a step-by-step explanation of how a driver for new hardware like MOD-IO board connected to OLinuXino via UEXT is created. MOD-IO boards have relays and ADCs which will be made available for use in Linux user space via the written driver.

Of course there will be other interesting lectures about Android, FirefoxOS, Tizen etc.

Do not forget that on Sunday 29th of June at the Olimex training building we will run Hardware and Software Hackathons.

Image

There will be a soldering workshop for the well-known FOSDEM Arduino clone board, where you will be trained how to solder alone your first Arduino and then program it and use it.

There will also be two Software tasks for the Hackathon:

 

Image

To make fancy web interface for controlling an interactive RGB LED table: the RGB table have 8×8 RGB Leds which are addressable individually and four proximity sensors at the four sides which detect if someone sits on this side.

 

Image

The second task is to do same for the Coctail-Mixing-Machine – it has 6 fluid pumps connected to the relays which could be opened/closed for a certain amount of time; controlling the volume of the drink in the recipe, flow sensors will give feed back if the fluid is flowing through the pipes; RGB addressable LEDs will be put under every bottle and pump which will make a LED animation while preparing the drink or will signal when the bottle is empty.

Both Hardware tasks will be performed with OLinuXino and all hardware resources will be available through User space APIs, so if you want to participate start thinking in advance and surprise us with your solution 🙂

Everyone who participates in the Hardware Hackathon will keep the Arduino board they built for themselves as a prize.

For everyone participating in the Software Hackathon there will be FOSDEM board prizes and the best solutions will win two A20-OLinuXino-MICRO.
