TuxCon 2016 highlights – two days fun with open source hardware and software

tuxcon

TuxCon free and open source software and hardware conference was last weekend in Plovdiv.

This is local, small conference which once per year gather enthusiasts and people who love open technologies at one place.

The event started on July 9th at 11 o’clock with Trayan who spoke about Java Robotics or how do you program Lego Mindstorm in Java:

then Yassen spoke about the future of Jitsi Meet

Damyan followed with serious topic explaining how different Linux distributions deal with security updates in a quite a funny way involving such a famous Bulgarian folk singer like Mr. Milko Kalaydjiev in Linux Matter (the video will worth watching).

Roland who come from Cambridge, UK specially for TuxCon presented us his ideas about the future of the education:

Then we had lunch break with sandwitches and the famous TuxCon cookies:

After the lunch was one of the most anticipated talk this year: about the Retro Computer Puldin.

Puldin is local Plovdiv pride, the only computer designed from scratch in Bulgaria both hardware and software. On TuxCon 2015 we invited people who designed the hardware to talk, this year we invited the software developer teams. Mr. Nedialko Todorov who was director for this project talk about how the idea to make Puldin come and how it was realized.

puldin1

Puldin design started in 1988 at that time already IBM-PC was on the market with 8088 processor from Intel working at the lighting speed 4.77Mhz. The developers decided to make the new computer software compatible with IBM-PC, so files from IBM-PC disk can be read/written and cross-compiled. At that time all electronic developments should have used Bulgarian electronic components so they choose CM601 which was copy of Motorola 6800 – 8-bit processor.

They made their own BIOS, DOS, Pascal compiler, BASIC, text editor same as famous PE2 (all this written in assembler!).

orlin

Orlin Shopov who leaded the software development team at that time shared that they had to fit everything in 16KB of ROM memory and at the end they had no single byte free!

The result was that the BASIC code on Puldin (with 6800 @1Mhz) was running faster than same code written on IBM-PC (8088 @4.77Mhz).

The BASIC interpreter of Puldin was written by Todor Todorov more famous with the Eddie viruses he wrote later (a.k.a. Dark Avenger).

For this talk four members of the team come together:

Puldin computers were at TuxCon also:

people could see what is inside:

The next talk was no less interesting. Edmund come from Vienna to talk about FOSS tools used in FPGAs:

edmund

He explained why we also need open source IPs. The FPGA vendors offer IP blobs which are “free” to use, but they are huge and you actually pay them in the price of the bigger FPGAs you buy to use them. Good example was for HDMI IP which FPGA vendor give away for free but use many different modes and resolutions which you may not need but have to use. Open Source HDMI design tailored to your needs may fit in 10 times less resources.

In next lecture Lubomir talked how he is attempting to create 3D model based on 2D pictures taken with his phone, quite interesting topic and interesting results:

lubo

Then Dimitar show us how to build custom Android images:

mitko

Delian has announced to talk for OpenSCAD but instead of this he talked about his dream to move the manufacturing from China back to Bulgaria 🙂 and to do manufacture on demand with new technologies like 3D printers, DIY assembly machines.

delian

In the next talk George was talking for creating web sites with open source technology, he dedicated his talk to Ian Murdock

george

Stoyan shared in the next talk his experience with setting up corporate servers. He wanted to bet that in 90% of the public administration running Microsoft server solutions are set to default configuration with no cache enabled etc etc which effectively kills more than half of the performance potential hardware has. Anyone want to contest his statement?

The first day closed with Lighting talks and interesting Quiz.

Day 2 continued in Olimex training building. We have just 50 seats there but around 70 people come 🙂

Fortunately Dimitar Gamishev has bring 10 meter radio antenna with some Radio sniffer, so some people were there and enjoying listen to space stations communication and local police which obviously do not care to encrypt their channels 🙂

BNR (Bulgarian National Radio) posted about TuxCon today.

The conference start at 11 o’clock with Reactive Java Robotics, Jitsi Meet, Security updates in GNU/Linux distributions and Open source in Education Welearners  project.

After the lunch we will continue with Retro Computing, Open Source tools for FPGA, How to calculate 3D coordinates with 2D camera, Android customization, Open SCAD, How to use Open Source for corporate needs, MOVI voice recognition with Arduino.

Lighting talks at 18.00 will close the first day and we will move to the traditional beer party in popular Plovdiv pub with Free Beer from TuxCon sponsors (Free as Beer not as Speech 😀 ).

In Sunday three workshops will be held in Olimex training building, starting again at 11 o’clock.

Reactive Java robotics, Open Source Hardware Robotics and First steps in FPGA for absolute beginners.

Open Source Hardware Robotics – we will talk about our attempt to re-invent the popular mechanical robot hand from the past Robko, but with complete new mechanics and controlled via Internet with ESP8266 WiFi and JavaScript API. We will show the problems electronic engineers face when attempt to do mechanical projects.

FPGA for absolute beginners will introduce in popular way what FPGAs are and how they evolved with time, how they are programmed. We will emphasis on the first FOSS tool to work with FPGAs – IceStorm and we will make our first blink LED demo, then will take look at more sophisticated code of video generation and how to make small game like Flappy Bird on iCE40HX1K-EVB.

TuxCon 2016 the conference for Open Source Software and Hardware technologies in Plovdiv is approaching.

In Saturday the organizers prepare dense program with 8 lectures, Lighting talks and ending with Free (not as in speech) Beer Party thanks to the event sponsors!

Edmund Humenberger (http://icoboard.org/) is one of our confirmed speakers, he is Open Source evangelist worked as a Open Source Expert for the European Commission and do currently work on bringing an open source FPGA toolchain to the world.

Orlin Shopov is one of the software developers of Puldin computers manufactured back in 1988-1992 in Plovdiv. He accepted our invitation to come and speak and have idea to invite and bring all other people who were involved in the design and production of this unique 100% made in Bulgaria (no clone of Apple or Oric like Pravetz) retro computer. This will be celebration for all Retro Computer fans who come.

Many other talks are submitted and we wait more to come by May 15th when is the dead line.

In Sunday at Olimex building we will have two workshops:

First is for  FPGAs, with introduction which talks about how FPGAs are made, where they are used, the history around them, the different ways of programming, HD languages, with practical work – using iCE40 FPGA and Open Source tools you will be able to understand the design process flow and to write your first program in Verilog and run it on the board.

We will give away 10 boards to random people who attend this workshop, so you can challenge your luck!

The second workshop will be with Robotics topic and we will keep it surprise by now, but will include competition and will also have prizes.

TuxCon 2016 – Free Open Source Software and Hardware event in Plovdiv is 9-10 of July

TuxCon 2016 will be on 9th and 10th of July 2016 in Plovdiv 🙂

This year will be the third issue of this conference dedicated to Open Source Hardware and Software.

Many people are confused and think that Olimex is the organizer of TuxCon, which probably caused the mistake in the Hackaday article.

The real credits should be for the people who stand behind TuxCon organization and they are these 10 enthusiasts: Leon Anavi, Vladimir Dzhuvinov, Rangel Ivanov, Atanas Palavrov, Dimitar Gamishev, Stefan Saraev, Stoyan Germanov, Radoslav Kolev, Nikolay Apostolov, Tsvetomir Denchev.

We at Olimex are just helping as we love to support such even in our city.

As always the event will be free to participate, Friday 8th of July evening there will be traditional beer welcome party for the guests and lecturers.

On 10th of July in Olimex training building there will be traditional soldering Hackathon and FPGA basics course for beginners.

If you want to make talk at TuxCon send proposal to the organizers at info@tuxcon.mobi

 

TuxCon 2015 – two days of fun and hacking

tuxcon

TuxCon is gone, but it was cool event with lot of talks about Open and Free Software and Hardware, lot of ideas exchange and many peoples learned new skills and stuff.

What you see above is the Saturday (July 11th) agenda. There were lectures about FreeCAD, Firefox OS, Arch Linux, Software testing tools, Crypto telephony, JavaScript Robots, IOT Firmware and etc.

The videos are already online.

The organizers made nice T-shirts:

I tested them personally they were delicious 🙂

The Kirov hall where TuxCon lectures were present was full:

tux

Peter present news around IoT Firmware for ESP8266:

pet

there was live demo, with ESP8266-EVB connected to MOD-RGB8x8 display made by 6 bricks making 48×8 pixel display where messages from twitter were captured with hacktag #tuxconmobi and displayed in real time, making simple internet connected display. Needless to say this demo was done for 30 minutes and we forgot to put bad words filtering which was abused a little bit by someone 🙂

Twitter demo is on GitHub. Here is code snip how easy you can print on RGB display with JavaScript:

twitter.on(
 'tweet', 
 function (tweet) {
    console.log('TWEET: ['+tweet.user.name+'] '+tweet.text+'\n');
    messages.push(
       {
       // User name and tweet text
       text: tweet.user.name+': '+tweet.text,
       // Color CYAN
       color: {r: 0, g: 1, b: 1}
       }
    );
 }
);


At the end there were lighting talks, I spoke about our new Energy Efficiency module for ESP8266 and WIFI-triple power switch which allow 3 different appliances to be commanded through Internet and Javascript and module which logs on cloud your energy consumption.

At the evening there was beer party with free beer from TuxCon sponsors:

Sunday we continue with the practical part: SMT soldering workshop of binary watch:

binary

Ultimate geek watch which show date and time in binary format and you can test how good are your friends in reading binary numbers.

For many people SMT part soldering seems like something very difficult, but it’s quite opposite, you can solder SMT parts very easily.

Everyone who came at the workshop built his own binary watch.

There were three easy steps: applying solder paste, placing the components on their places, soldering with hot air gun.

To apply the solder paste you have to put the PCB between some holders:

bina

then to put stencil above and keep it in place with tape:

paste

then to apply paste with rubber raquel, then to put all components on their places watching for the components which have polarity:

diy

it’s easy, even girls can make it 🙂

grls

… actually girls usually do it better 🙂

then solder the components with hot air watching to not put on fire the wooden desk, you can see we use ceramic tile for this purpose:

binar

Some small components were lost, some plastic buttons were melted by the hot air, but otherwise everyone did good job and almost all binary watches worked!

Now looking around on the internet we got new idea how next TuxCon 2016 Tshirts should look аlike, and idea for the next workshop board with LEDs:
