It’s Friday again and time for our Guess What is this Quiz

We just finished the routing of this new board, so the question is Guess what is it?

It uses Quectel EG21-G module which works anywhere in the world covering all GSM standards and frequencies. It also has GNSS build-in.

It also can connect to any network 2G-3G-4G whichever is available (sorry no 5G yet 😉 ).

Once the prototypes are ready and check we are preparing Crowd Supply campaign for it! Hint Fits perfect to LoRa-GATEWAY and allow connection where no wires and optics like mountain hubs, remote areas etc.

You can post here or retweet/share/boost on Twitter/Facebook/Mastodon/Diaspora and in Monday we will let Random.org to decide who will win one of our new eduArdu educational board.

Have a nice weekend!

UODATE 22-04-2019: Random.org selected @netsigi as winner!

 

Open Source Hardware ESP32-POE-ISO is now in stock and we are very proud with the result

ESP32-POE-ISO-2

We are very proud of our new ESP32-POE-ISO and delighted to announce it’s already in stock ready for order!

What we did with this improved version of the low cost ESP32-POE power over ethernet solution for IoT?

  1. As many requested we add 3000VDC galvanic insulation. Now you can program / debug while connected to PoE switch or router;
  2. Many asked for more GPIOs so we set SD-card in 1 bit mode and this way released 3 GPIO pins for other use;
  3. We got hints that new Espressif SDK allow ultra deep sleep modes for ESP32 and we re-designed the power supply part that now the ESP32-POE-ISO has consumption down to 200 uA (130uA of which are taken from ESP32-WROOM-32D module). The rest board without the module consumes just 70uA;
  4. As per your request now battery level has option to be monitored with the ESP32 ADC;
  5. There is External power detection option, so your software will be aware when run sole on battery and when have plenty of power.
  6. The Isolated DCDC we use is 2W and provides 400mA @5V, 100mA are reserved for the battery charge (available if no battery is connected) and 100mA are provided for ESP32, which leaves up to 200mA @5V for your additional circuit.

We love to listen to our customers and we did our the best to complete most of the requests we got with this new version.

openSUSE leap 15 on the TERES-I

images

Torsten Duwe send us note that he is working on openSUSE Leap 15 image for TERES-I which is at same state like the Armbian image.

For these who are interested they can follow the progress here.

TERES-I Open Source Hardware Laptop has new experimental Armbian Mainline Linux image for download

TERES

We uploaded few days ago Armbian experimental mainline linux image for TERES-I on our ftp.

There are still few known issues which we work on, but we wanted to upload this experimental image so other people can start playing with.

What is new?

  • eMMC now run x3 times faster which improves the overall user experience.
  • OpenGL with LIMA

Known issues:

  • Automatically turns on upon applying power via the PWR_JACK, we need time to patch mainline uboot
  • No sleep or suspend, WIP.
  • Bluetooth not working out-of-the-box – fixed in Olimex release if you install the package
    ftp://staging.olimex.com/Allwinner_Images/A64-Teres/linux/armbian_experimental/teres-bluetooth_0.2-1_arm64_armbian.deb
    with command:

    dpkg -i teres-bluetooth_0.2-1_arm64_armbian.deb

  • Keyboard LEDs not working – fixed in Olimex release – install the package

    ftp://staging.olimex.com/Allwinner_Images/A64-Teres/linux/armbian_experimental/teres1-ledctrl_0.1-1_armbian_arm64.deb

    with command:

    dpkg -i teres1-ledctrl_0.1-1_armbian_arm64.deb

  • The LCD brightness is low by default (20%) – fixed in Olimex release – to increase it type in the console

    echo 9 > /sys/class/backlight/backlight/brightness

  • no video player acceleration, to be fixed in the next release planned for 22.02.2019

 

FOSDEM slides and video

DyUvHPPXcAADnIH

FOSDEM is always impressive, even for people like me who go there for 7th time. It’s great place where you can see developers for almost every FOSS big project and talk face to face.

It’s really pleasure to see that last years there is Hardware related dev rooms too.

KiCad as always attracted lot of attention

DyeknEdW0AUyjbH

but CAD and OSHW devroom was pretty small, so people are waiting on long tails to get in and just few lucky ones succeed:

For security reason the organizers didn’t allow people to stay standing or sitting on the floor, but this didn’t stop all. Next day I spoke to lot of friends and they said – I knew there will be no space for all who want to enter, so I just stay at the cafeteria and watched the stream.

It was same situation at the Andre Przywara talk One image to rule them all. There was no space in the room to accommodate all people who wanted to attend it.

There were three talks from Plovdiv at FOSDEM this year 🙂 Our friend Leon Anavi had two talks Making Open Source Hardware for Retrogaming on Raspberry Pi and The Software Developer’s Guide to Open Source Hardware. It’s cool as his full time job is as software engineer but as you can see he does OSHW in his free time and obviously like to talk more about his hobby than his daily work 🙂

I talked about some new OSHW boards we are working on last few months.

The idea is to build LoRaWAN infrastructire and install some free Smart City solutions in Plovdiv which to set example and to put all our work on GitHub so if other cities want to follow to be able to replicate and scale what we did and hopefully people to get aware more about the power of the open source hardware and software solutions.

Here are my slides and here is my attempt to speak English at FOSDEM. Sorry subtitles are not available 🙂

It was incredible pleasant surprise to see OLinuXino-LIME2 mentioned in Danny Haidar‘s lighting talk Creating a Computing Revolution: from Personal Computers to Personal Servers.

First Steps with Snap4Arduino and eduArdu tutorial in Bulgarian and video is GitHub

Screenshot from 2018-12-20 14-22-20

Our Bulgarian customers often blame us that we post and make documents in English, but we really think that if one decided to work in IT industry and deal with programming and electronics should learn English and supporting documentation in two languages just double the burden for us.

eduArdu is educational board targeting kids so it’s a different story. This is why we made small tutorial how to use eduArdu with Snap4Arduino in Bulgarian language and uploaded it to GutHub in PDF and ODT format.

On Youtube we uploaded video for the same with English text.

So we hope now both English and Bulgarian customers will be pleased 🙂

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.
