Ultrasound levitation soldering kits will be present at OpenFest for soldering workshop

Sound travels approximately at 343 meters per second. When two speakers are placed opposite one another and they generate sound with same phases, then acoustic standing sound waves are formed.

These sound waves have enough power to keep small objects in the air.

The wave length is calculated by dividing the speed of sound by the sound frequency. Our speakers are 40Khz ultrasound transmitters and the sound wave length is 8.5 mm long.

Ultra-Sound-Levitation soldering kit contains everything needed to build such a standing sound wave generator.

On 14th October is the 20th issue of Open Fest – the biggest Open Source event in Bulgaria.

Olimex will have its traditional soldering workshop there from 10.00 to 18.00 o’clock.

Participation in both OpenFest and the soldering workshop is completely free of charge.

Everyone who wants to test his/her soldering skills is welcome. Olimex employees will help you with the soldering and guide you at the workshop.

For these who can’t participate in the workshop, the Ultra-Sound-Levitation soldering kit is available on Olimex web site for sale and can build one at home.

FOSDEM 2020 Bruxelles 1-2 of February OSHW room and soldering workshops

FOSDEM is this weekend and we will be very busy the two days!

Saturday 01.02.2020 at 10.30 will be my talk in “Open Source Computer Aided Modeling and Design devroom” “Designing and Producing Open Source Hardware with FOSS/OSHW tools”

Sunday 02.02.2020 at 13.00 will be my talk in “Hardware Enablement devroom” “Open Source Hardware for Industrial use”

The great news is that this year FOSDEM organizers let us have whole OSHW room UB4.228 where we will have two days Soldering workshops:

Saturday we will solder PTH components with special board we made for FOSDEM – FOSDEM-MUSIC-BOX

Sunday we will proceed with more advanced SMT soldering workshop of Binary-Watch

The soldering workshop participation is free as in beer and everyone is welcome.

We will bring with us limited number of 100 pcs FREE FOSDEM-MUSIC-BOX soldering kits for Saturday and 100 pcs FREE Binary-Watch soldering kits for Sunday.

We also will take with us soldering tools to equip 10 soldering seats. If you want to join and already have soldering iron, twizzers, magnify glass, wire cutters please take them with you and spare time on waiting on tail to get free soldering seat.

Also if you want to assembly some of our other soldering kits listed here (or any other boards) you can send us email at info@olimex.com with the boards/kits list you want to purchase and we will deliver to FOSDEM so you save shipping fee.

Lastly there will be plenty of space in the OSHW room, so if you have interesting project to show off or just want to chat about OSHW topic you are welcome, let’s make this room meeting point for Open Source hardware enthusiasts at FOSDEM.

FOSDEM 2020 – the must see EU biggest Open Source Technology event is approaching

If you work with Free Open Source Software and Hardware and you never have been on FOSDEM you don’t know what you are missing!

This is huge and every year becomes bigger. Join 8000+ hackers all around the world and watch your favorite talks – you can always find something interesting among the 480+ talks which will run during FOSDEM weekend 1-2 of February.

There you can meet lot of leading Linux and FOSS developers face to face.

I have two talks there:

• Saturday in Open Source Computer Aided Modeling and Design devroom
• Sunday in Hardware Enablement devroom

We are also promised dedicated Open Source Hardware room UB4.228 yay!

We are preparing special PCB and will run Soldering Workshop there

It’s music box, programmable with Arduino IDE, specially designed to be easy to solder by beginners.

As always the soldering workshop will be completely free (as in beer) to participate 🙂

In this room will be plenty of space and everyone who have interested in Open Source Hardware and want to come to show off something or just to chat is welcome.

So clear your agenda for February 1st and 2nd and book your flight to Bruxelles!

Looking forward to meet you there!

OSHW Audi style Bike Turn Signal LED Lights soldering kit is ready for Open Fest Workshop

Bike-TSL-Kit now is ready and we are looking forward to see you at Open Fest Workshop.

As always the workshop will be free to participate.

Do not forget to book kit by e-mail to info@olimex.com for Open Fest Workshop, as we will have just 100 kits for the workshop.

If you have soldering iron, twizzers and cutters take them with you as we will provide 6 sets, but previous workshops proven there will be long tail of people wanting to participate/solder and having soldering tools will spare you the waiting.

Here is small video clip how Bike-TSL-Kit works when assembled:

We are looking forward to see you there and have fun together!

Come to Open Source Hardware Day on October 19th in Plovdiv and learn about how Open Source Hardware is made.

The Open Source Hardware Association OSHWA.org choose October 2019 to be month of the OSHW. The idea is to have events all around the world which to popularize Open Source Hardware.

Here you can see the full list of registered OSHW events you may find interesting event in your country.

On October 19th in Plovdiv is the Open Source Day. It will be held at SiteGround and starts 11.00.

Come to learn about:

• What is Open Source Hardware;
• How to design electronic boards with KiCad;
• How to prepare your files for PCB production;
• Where to source your components from EU/USA/China;
• How to assembly your boards;
• How to certify your project as OSHW;
• How to organize crowdfunding for your OSHW project production;

As all other events organized by TuxCon, SiteGround and Olimex  this will be free to participate.

Open Fest 2019 is approaching,the traditional Olimex Soldering Workshop this year will be: Pimp your bike with OSHW Audi type turn signal lights

Open Fest is the biggest and most anticipated Open Source Technology event in Bulgaria!

This year it will be held in Sofia Tech Park November 2nd and 3rd.

The site already has CFP link where you can submit your proposal for talk.

Olimex submitted proposal for the traditional Soldering Workshop.

This year we prepared very interesting Open Source Hardware kit: “Pimp your bike with Audi like turn signal lights”, here is teaser. We use x5 pcs 10mm round LEDs on bothe sides, total PCB length is around 20 cm.

and back side:

it comes with pair of switches which allow you to activate left and right side lights.

This design is made purely analog, no processors, no programming. The design files will be uploaded on our GitHub account so anyone who has no chance to come can do his own version. Also we will have the kits on our web for sale after OpenFest.

On the workshop we will explain how it works, so you will learn what resistor divider is, what analog comparator is and how we achieve the Audi effect with the LEDs.

As we are preparing only 100 kits and there may be lot of people who want to participate, we solicit you to pre-register at info@olimex.com to have kit reserved.

As always our number of soldering irons are limited, so if you have your own, bring it to the workshop with you to speed up the process 🙂

Looking forward to see you at Open Fest!

 

TuxCon 2019 soldering workshop kits are now on our web for sale

The soldering workshop this year was for Open Source Hardware Universal Remote Control board using SMT components.

All files for this kit are at GitHub including hardware, software sources and Assembly instructions. For these who didn’t manage to participate, now the kit is on our web for sale: URC

This year we had massive participation of kids from 4 to 12 years old.

As the SMT components are bit odd to solder we prepared for them FOSDEM-85 kits with PTH components.

We were a bit concerned if they will not get burned by the soldering irons, but they surprised us as they were so precise and careful that all boards they soldered worked 100% from the very first time.

Just for comparison when we do soldering workshops with adults from 20 up to 70 years old about 10% of the soldered boards do not start due to problems with misplaced components or bad soldering and we have to help them to fix. So it appears kids do solder better than adults 🙂

The Minibot kits from TuxCon 2018 soldering workshop are also on the web now.

It was wonderful weekend with lot of fun.
