Open Fest is this weekend! Welcome to the TuxCon-Kitty SMT assembly and programming workshop in Saturday!

OpenFest

Open Fest conference is this weekend 4-5 of November! This is the biggest Bulgarian FOSS event.

Here is the program.

We will run the traditional soldering workshop in Saturday and will solder TuxCon-Kitt boards then learn how to program them. The workshop is free (as in Beer) to participate 😉 i.e. no money will be involved just your enthusiasm and motivation to learn new stuff.

TERES I assembly workshop this Saturday!

workshop

This Saturday 21st of October we will have TERES I assembly workshop!

Customers from Bulgaria who placed orders for TERES I DIY Open Source laptop will have their laptop kits ready and are invited to come and we assembly them together!

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.

Beware of Pseudo Open Source Hardware EKG/EMG fakes of our shields by Duinopeak company

KZB_0039-EKG-EMG-SHIELD-kit-1-500x500

We got support question for Arduino EKG/EMG shields which do not work correctly.

We did the initial questions to make sure they use correct drivers and software, and it seems the customer did everything correctly but couldn’t get correct signals but only noise. Then we asked him to send us picture of how he is connecting the boards.

To our surprise we got picture with blue mask boards. All our EKG/EMG boards are with red mask, so we found these guys easily. All their contribution back was to remove Olimex from the silkscreen and to put their name on the boards, although they keep the OSHW logo they didn’t put their CAD files available for download, which is not great loss as they didn’t contribute at all except to change text on the boards.

On top of this probably they didn’t even test the boards as the one in this particular customers didn’t work.

What is most annoying is that they link all our files to their web page, so mislead people that they buy our boards.

What happens with Arduino project?

Arduino is always pointed as example for successful Open Source Software and Hardware project.

With thousands of contributors and millions of users this project is bespoken leader among microcontroller development.

No one remembers the tools used before Arduino.

There were few attempts to fork it for other platforms like Maple for STM32, Energia for MSP430, MPIDE for PIC32 but they never managed to make enough critical mass outside the main Arduino project and then simply were absorbed in Ardino IDE when it got possibility to merge different processor platforms. That was the end of all forks.

All this amazing progress would not be possible without Arduino being Open Source and the help of the thousands contributors.

With the success came the money and as always they were subject to disputes and all we know for the battles inside the Arduino team in the court.

Last year the problems have seemed to be resolved and Arduino Foundation was created and this was announcement as “new beginning”, but meantime some bothersome things were noticed by Open Source community.

All hardware projects listed on arduino.org are announced to be open source hardware, but none of them comply with OSHW definition. The sources are with status “coming soon” years after their release, or where these sources are available there are hidden black boxes which actually spoil the whole idea to allow other people to study, modify, improve and reproduce the design.

Makezine has published article this month with some bothersome facts about Federico Musto who seems to own major shares in the new formed Arduino foundation.

Wired also published article on this issue https://www.wired.com/2017/04/arduinos-new-ceo-federico-musto-may-fabricated-academic-record/

Meantime Philip Torone from Adafruit posted message on OSHW mailing list with list of boards on Arduino.org with problems in OSHW compliance

So many people now ask themselves the question: Is Arduino project hijacked and turn in to Closed Source Project and how this will affect the Arduino community in future?

iCE40HX8K-EVB OSHW FPGA board is in stock

iCE40HX8K-EVB-1

iCE40HX8K-EVB is upgrade of our iCE40HX1K-EVB with more logic cells FPGA so bigger Verilog projects could be synthesized.

GPIO1 34 pin bus is same as iCE40HX1K-EVB and all DAC, ADC, IO, etc modules are compatible, on top of this there are plenty of additional GPIOs on 4 40 pin 0.05″ step connectors.

512KB fast SRAM is on board, with iCE40-IO board you  can connect VGA monitor and PS2 keyboard, so you can make your own custom CPU (for instance RISC-V) computer with monitor and keyboard.

Sunday June 4th we start at 11:00 in Olimex train building at 2 Pravda St.

We will have brief presentation about how to solder and basic knowledge for the electronic components, then we will solder the specially made for TuxCon Kitty badge and learn how to program it with Arduino IDE. 100 badges are ready as kits and will be given away free of charge, but we have limited number of soldering irons, so if you have one bring it to the event 🙂
Members of the local Radio club will install huge antenna at our backyard and have fun like last year.

TuxCon is totally free event made by volunteers in partnership with Technical University in Plovdiv. No need for registration, no entry fees.
Looking forward to see you this weekend in Plovdiv 🙂
