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

Bike-TSL-Kit

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!

The slides from Industry 4.0 meeting in Stuttgart are online

zve-frauenhofer

Open Source / Free Software for Effective Industry 4.0 Meetup  organized by Nexedi GmbH  and hosted by Fraunhofer IAO was held on 12th of November in Stuttgart.

There were quite interesting talks mostly focused on Open Source Technologies and their possible use in Industry 4.0.

My slides are now uploaded at Slideshare.

This is FOSDEM 2018

fosdem1

Last weekend in ULB (University Libre of Bruxelles) took place the biggest Open Source event in Europe – FOSDEM.

With 678 talks, split in 55 devrooms this is something every open source enthusiast waits whole year.

It’s amazing how the organizers make such event possible, between 8 and 10 000 people all around the world come together at one place. If you want to meet some open source project, Linux kernel or Linux distribution maintainer there is great chance to meet him/her there.

FOSDEM usually is made in the weekend Saturday and Sunday, but traditionally starts with Friday evening welcome beer party at Delirium cafe. Do not be fooled by the name nobody go there to drink coffee.

Delirium usually can’t hold all people so the streets around it looks like this:

Every year this event become bigger and bigger. I was always wondering how they manage to keep their WiFi infrastructure in order with so many people attending. This year for the very first time the WiFi was impossible to connect to, so I guess we reach the infrastructure capacity 🙂

In Saturday the talks started, needless to say for me most interesting was the CAD and Open Hardware devroom.

One of the most anticipated talk there was about KiCad 5 new features.

Wayne Stambaugh the project manager started his talk with red T-shirt from Digikey and announced that Digikey made the single most significant donation to KiCad team just few days before the conference. So he said them “thank you” by presenting his talk wearing their red T-shirt.

It was very interesting to hear that Wayne got feedback from popular PCB prototype providers, that about half of PCB projects now they receive for prototyping production are made with KiCad! It’s amazing to see the progress KiCad made for the last 4 years!

I personally like more the T-shirt Wayne was wearing when he closed his talk 😉 KiCad team really like the complex boards we design with their product and this was very kind gesture.

Another interesting talk was Introduction to LibrePCB . This is the first time I hear about this project and it looks itneresting. The author is obviously capable young man and thinkered a lot about how to make component libraries more easy to use, but while I was watching the talk I was wondering (as many others) why the author just do not join KiCad, which is already well established project and leading as features and completeness. We all know that KiCad team is very small and more people joining the project will make much more sense than to re-inventing the hot water, because you do not like some feature in this popular project. Well this is the open source 🙂 and everyone is free to scratch his own itch, but I would love to see Urban Bruhin helping KiCad to become better instead to duplicate the work creating similar product alone.

Jesús Arroyo Torrens presented Icestudio – graphical way to program FPGAs. I would say this is quite entertaining and easy start for beginners with no previous knowledge about electronics.

Juan Gonzalez-Gomez (Obijuan) upgraded this talk with very entertaining presentation about what he did with Icestudio and small funny blocks he created. He is using his daughter as beta tester. I recommend you to watch this talk when the video is available.

Juan and Jesus are part of Spanish community working with FPGAs. You can see more about what they do on this site FPGAwars.

Staf Verhaegen shared his findings about is it possible today to implement ASIC design with open source tools. Very interesting topic, let’s hope the time Makers and small companies will be able to make their own chips with Open source tools is approaching.

My talk was about current TERES laptop status and the experience we got during the development with KiCad. Using FOSS tool like KiCad is great to make OSHW, but if you want to use latest features and the daily builds, they are available only via ppa repository for Ubuntu. This means if you use other distribution you have to build from sources every day. Windows daily builds are not available at all. This confuses many beginners who can’t manage to open our files when they want to study them as they use old builds (official Ubintu repository KiCad version is probably one year old, same for Windows version). My slides are now uploaded at Slideshare.

Other devroom talks I found interesting:

Exploiting modern microarchitectures Meltdown, Spectre, and other hardware attacks 

Programming UEFI for dummies 

Improving Linux Laptop Battery Life

Kodi and Embedded Linux

Linux as an SPI Slave

How to keep your embedded Linux up and running

Drive your NAND within Linux

Image capture on embedded linux systems 

New GPIO interface for linux user space 

It was nice to see three four other talks at FOSDEM by Bulgarian speakers!

Automating Your Lights with Open Source 
Turning On the Lights with Home Assistant and MQTT
Testing Red Hat Enterprise Linux the Microsoft way 

Current meta of video compression and probable futures

Overall FOSDEM is must see event for anyone who is interested in FOSS/OSHW.

Bruxelles is excellent location and offers lot to see, both Wizzair and Ryanair offer low cost flights to this destination and I don’t know where else you can drink beer from half meter glass (not half litter but half meter!) so looking forward to see you next year there!

The assembly workshop will be in OLIMEX Training Building and will start at 14.00 o’clock.

No need to have Laptop kit to participate, everyone is welcome to join us.

A20-OLinuXino-MICRO works hard inside Open Source Rover Octanis project in freezing Antarctica!

r3

One year ago we got request for sponsoring 5 pcs A20-OLinuXino-MICRO for Octanis project from group of students at EPFL, who are making an open source rover (http://octanis.org/rover) that will go to Antarctica.

Their goal was to use A20-OlinuXino-MICRO as a communications base station with LoRaWAN and to use it for onboard image processing of their stereoscopic camera images.

r1

Needless to say the magic words “open source rover project” closed the deal 🙂 We shipped the boards in December 2015 and yesterday got e-mail that the rover operates since February 2016, but he was moved to Antarctica in November and will stay there till February 2017.

You can track the rover position right now at http://octanis.org/constellation/

On GitHub you can see their 3D parts CAD files and all firmware running on the rover. You can reproduce this project with 3D printer.

 

 

 

Open Fest 2016 – Soldering of the Open Source Hardware GHOST

“A ghost is haunting Europe—the ghost of communism.” said Carl Marx in 1848

We can re-phrase “A Ghost is haunting OpenFest 2016 – the ghost of open source hardware” 😀

We created this Soldering Kit specially for Open Fest as third year in a row we do soldering workshops there:

oshw1

It’s a very simple board, specially made for novices with small PIC10F206 microcontroller which has only 512 words of Flash memory and 24 bytes of RAM, still enough to write C code like this.

In the good Olimex traditions being overwhelmed with work we totally forgot for the soldering workshop and started the project 3 weeks before OpenFest 🙂

The board was quickly routed with KiCAD and we sent to PCB manufacturer in China, who keep the promise to make the blank PCBs for 1 week and shipped on time but DHL late with the customs clearance and we got the board Friday morning! The workshop was Saturday and Sunday, right on time!

Then we had half Friday fun with Microchip’s MPLABX tools, which refused to re-program the PIC10F206 once it’s programmed.

After few hours we found that MPLABX version 3.35 can program and erase PIC10F206 just fine but MPLABX 3.45 don’t.

Still there was enough time till 20.00 o’clock and we managed to program 200 kits ready for soldering next day 🙂

The initial intention was to make LED breathe but after losing so much time with MPLABX we decided the first version to be simple 10 times blink!

Here you can see people assembling it on OpenFest:

openfest

Girls, Boys, Kids all were not afraid and took the soldering irons:

openfest2

openfest3

After OpenFest we continued to investigate why the newer MPLABX refused to program PIC10F206 more than once, the problem was trivial, to erase it the Vcc must be above 4.5V:

voltage-configuration

Still interesting why MPLABX 3.35 was erasing it even without this voltage settings 🙂

This is why working with embedded systems is such fun. You never know where you can step aside and you have to worry not just for the code but also for the hardware as source of mistakes.

Needless to say we had no any assembly instructions for the kit at OpenFest, but now proudly we put them on the web site of the kit.
