Open Doors Day for “Computer System and Technologies” department in Technical University Plovdiv

KST

For all students whо didn’t decide yet where to continue their education the “Computer Systems and Technology” department in Technical University Plovdiv will have Open Doors Day this Friday 28/11 in Hall 2112, II building on bul. St Petersburg 63.

Open Fest 2014 and Hardware Hackathon with Adruino and Simon game

OF1

Open Fest is the biggest event for Open Source technologies in Bulgaria. This is the ultimate must visit event in the agenda of all Open Source enthusiasts in Bulgaria.

This year was our third time at Open Fest and the impression is that every next year it becomes bigger and bigger!

OpenFest is free to participate and managed by group of Open Source Enthusiasts totally on volunteer basis, instead to make money from this event they do the opposite they put their own money just to see at one place similar minded people and to make it one big fest.

You can’t imagine how friendly and spiritual is this event, celebration of the freedom in technology in software in hardware, the organizers even provide free breakfasts and coffee for everyone who come :) how cool is this?

You can judge that the event grows indirectly by the number of the sponsors who join it and every year the number of sponsors increase.

The halls now are small and can’t accomodite all the people who want to hear the lectures and next year probably some bigger space need to be found for this event as current location is already too small.

I had a talk for Programmable Home, presenting what we are working now on to make home automation easier. Two years ago at Open Fest 2012 I had lecture about Open Source Hardware and Business and when I asked who knows what OSHW is there were just couple of hards which rise, this year on the same question more than 1/3 of the hall rised their hands, it’s good to see people get more aware of Open Source Hardware.

The video is now online.

We also ran the traditional Hardware Hackathon, this time we had the Pinguino FOSDEM edition Arduino boards for assembly and the more advanced Simon game.

Soon our spot become magnet for interesting people and sweet small talks about Electronics, DIY, OSHW etc.

Time was flying so fast we couldn’t realize when it become 18.00 o’clock and the guards came to drive us out as they had to lock the building :)

Meantime there were quite of interesting lectures running like the Software Defined Radio and RTL by Harald Welte:

Or the application of Open Source Hardware and Software in the Mining Industry by Noac Engineering:

needles to say the heart inside this complicated system is OSHW A20-OLIMEXINO-MICRO :)

Svetlin Nakov lectures are always interesting, he is trying to break the obsolete education model in Bulgaria by running free and quality education in his private Software University. How he makes money out of this? Two ways: first – if you want official exam documents you pay small fee, second – the Software companies pay him well for the graduated students, so people can learn for (almost) free and then if they perform well on the exams they get good paid job. Svetlin is quite a mix of good ideas and the ability to present them well while making entertaining show. We need more people like him!

Hackidemia with Hackafe and Angel Georgiev in Plovdiv or how to sparkle the interest in Electronics in kids with Open Source Hardware

1

This weekend Angel Georgiev with the help of Hackafe volunteers made first Hackidemia in Plovdiv with Five different workshops made totally free of charge with the idea to spark the interest of kids for Electronics and Software.

First workshop was and the most advanced: OLIMEXINO-32U4 + Shield EKG-EMG + Shield EKG-EMG-PA allow you to play and analyze your muscle activities + MOD-EKG is used to read your pulse, then to display the info on ROPE-5 RGB LED rope.

The Second Workshop was for these who want to try their soldering skills and there were FOSDEM-85 Pinguinos and Simon-85 games to solder:

3 30 33 300 333 3000 30000

and here is the final result:

The Third workshop was music instrument made with OLIMEXINO-32U4 with couple of Ultrasonic sensors US-020 which change sound frequency and pitch depend on how close your hands are to the sensors.

both kids and mentors enjoyed to play with this electronic instrument:

The Fourth workshop was to build air quality measurement station with sensors for temperature, moisture SNS-DH11 and SNS-MQ135 for air polution quality, kids learned more about how to keep environment and air clean and with their own hands built station which attached to balloon and measured the air quality in the front of Hackafe office.

7 70 77 79 710 777 779 7676 7717  7878 79797 799999

 

The Fifth Workshop was made with OLIMEXINO-32U4 and SHIELD-LOL-SMT and was probably most creative for kids, they made their own animations on the LED shield and were very proud of the results :)

Here is video of spaceship animation.

 

 

 

Weekend Programmable Challenge – Week #69 – Levenstein distance

We got 7 solutions this weekend:

  • Python x2
  • C++ x2
  • Lisp x1
  • Php x1
  • C# x1

You can enjoy the solutions on GitHub as usual.

Weekend Programming Challenge – Week #69 Levenshtein Distance

74bc0fa858652701ff47bfd125c83eeb

Problem:

Levenshtein Distance  is string metrics for measuring the difference between two sequences. Make code which inputs two strings and calculate Levenshtein Distance between them.

The rules:

You can code the solution in any programming language during the weekend and have to submit it to info@olimex.com latest on Sunday November 18th.

On Monday we will upload the solutions on GitHub https://github.com/OLIMEX/WPC

You can play with your real name or with nick if you want to be anonymous, we will not disclosure your personal info if you do not want to.

 

New Set of LCDs in stock for OLinuXino now directly support LIME and LIME2 connectors

LCD-OLinuXino-15-1

We have now in stock 7 new LCDs with driver circuit which support 40 pin 0.1″ connectors like these for A13-OLinuXino, A13-OLinuXino-MICRO, A20-OLinuXino-MICRO, but also have LIME and LIME2 compatible 40 pin 0.05″ connectors.

You can see all of them here.

The 15.6″ LCDs now include Full HD 1920x1080p display.
