MOD-RFID1356MIFARE NFC / RFID reader writer for MIFARE 13.56Mhz tags

MOD-RFID1356MIFARE

MOD-RFID1356MIFARE is re-design of our popular RFID card readers. It’s based on NXP PN532 chip and can read and write in ISO/IEC 14443A/MIFARE tags.

Like with MOD-RFID125 and MOD-RFID1356 it’s extremly easy to use. It connects via USB to any computer and creates HID keyboard or CDC serial port. There is no need for any drivers and switching between the modes is very easy with one push button.

WiKi description explains how to use. Read distance is up to 15 cm for ISO cards. We will stock soon 4 different types of tags: ISO card, clamshell, keychain and adhesive sticker.

A20-CAN – new OSHW board designed with KiCAD adds CAN networking to A20-OLinuXino and A20-SOM

A20-CAN

Want to sniff your car’s CAN bus or to drive Industrial machines with CAN networking bus?

Allwinner A20 SOCs have CAN but almost no one use it. If I remember correctly it was not even included in the Allwinner documentation just two pins had CAN on their names, so many people doubt if there is or not CAN.

Fortunately some people investigated further and add proper CAN support for A20 Linux, so we decided to make small driver board which to allow A20-OLinuXino and A20-SOM to have CAN. What does this means? Now you can use A20-OLinuXino to talk to other devices with CAN like industrial equipment, automotive CAN bus etc etc.

Current Linux image we have is without CAN support, but we put instructions on our WiKi how to build one with Linux-Sunxi 3.4 Kernel and with Mainline kernel: https://www.olimex.com/wiki/A20-CAN

What you see above on the picture is our first prototype of A20-CAN it works well although we use 5V CAN driver and A20 is 3.3V device. We successfully connected AM3352-SOM-EVB to A20-OLinuXino-LIME with A20-CAN driver and exchanged some messages at the highest speed 1Mbit and it works fine.

All CAD files, Gerbers, BOM are in this Github account: https://github.com/OLIMEX/A20-CAN . The board is done with KiCAD.

The PCBs are now in production and in 2 weeks A20-CAN will be orderable on our web page . While the PCBs are made we will work to add the CAN in our official images, so you do not have to bother with Kernels configurations and re-compiling.

TuxCon 2016 schedule is now completed

TuxCon is only 49 days away! TuxCon is completely free event and every one is invited.

I got note from the organizers that the schedules for July 9th and 10th is now complete.

In Saturday the talks will be as usual in Plovdiv Fair “Kirov” hall and  starts at 11.00

Saturday July 9th:
11:00 – 11:30 Reactive Java Robotics and IoT, Trayan Iliev, Bulgaria
11:40 – 12:10 Jitsi Meet, Yassen Pramatarov, Bulgaria
12:20 – 12:50 Security updates of GNU/Linux distributions, Damian Damianov, Bulgaria
13:00 – 13:30 WELEARNERS “Make Create Learn Digital in Europe”, Roland A. Burger, Sweden
13:30 – 14:10 Lunch
14:10 – 14:40 Puldin retro computer, Orlin Shopov, Bulgaria
14:50 – 15:20 FPGA FOSS toolchain, Edmund Humenberger, Austria
15:30 – 16:00 How to calculate 3D pixel coordinates with 2D camera, Lyubomir Dinchev, Bulgaria
16:10 – 16:40 Android customization, Nikolay Dimitrov, Bulgaria
17.00 – Lighting talks:
OpenSCAD, Delyan Tsonev
Web sited with Drupal, George Atanasov

few words for the talks:

Trayan Iliev will talk about Java Robotics he will also make workshop in Sunday.

Jitsi Meet doesn’t need presentation as it’s very popular FOSS video conferencing software, Yassen Pramatarov will speak for the latest development with this platform.

Damian Damianov will speak for GNU/Linux security and what sane precautions we should take when use Linux distributions.

Roland Burger is our first guest speaker from University of Stockholm and will present his idea about the Digital Learning in Europe i.e. how to sparkle the interest for IT in kids in schools.

Orlin Shopov is one of the software developer of Puldin retro computer and he will speak about how it was born and probably we will see other members of the team who worked on it also.

Edmund Humenberger is our second guest speaker, he is from Austria and his interest is FPGAs and how to use them with free and open source toolchain.

Lyubomir Dinchev will try to introduce us to new approach for Computer vision with direct image processing trying to explain it without too much math

Nikolay Dimitrov will speak about the Android distribution for Amazon which is made in Sofia by MM Solutions.

It will be long day and it will end with Beer party at 20.30 in local pub in Plovdiv.

Sunday July 10th we will continue with three workshops at Olimex training building.

11:00 – 13:00 Workshop: Reactive Java Robotics and IoT, Trayan Iliev, Bulgaria
13:00 – 15:00 Workshop: Open source hardware robotics, Olimex
15:00 – 17:00 Workshop: Hands on FPGA, Olimex
Open Source hardware robotics workshop will be done with our recent experiments with Robot hand with ESP8266 WiFi link and controllable with JavaScript.

Hands on FPGA workshop will introduce our new iCE40 FPGA boards and surrounding modules with fast DAC, ADC, Digital IOs, VGA etc. All who participate will receive 20% discount code for ordering of these boards and modules.

Help day focus – SMT technology – Solder paste and what we should know about it

3D-Solder-paste-3

May 28th in Olimex training building we will have our Help day.

There we will discuss everything around electronics, but we want to add small twist to these meetings, so each time we make Help day we will add small focus theme with slide presentations and transfer some know how we have.

This help day focus will be around SMT technology and production and specially one of it’s very important componets – the Solder paste.

There are lot of myths and mysteries around solder pastes and we will try to remove them, so at the end of the day you know:

  • what is solder paste
  • what are solder paste most important characteristics
  • what types of solder paste exist
  • how solder paste should be handled
  • what happens after solder paste expire date
  • can we bring back to life old solder paste
  • how to trouble shoot problems related to solder paste

We will share things we learned during the last 25 years dealing with electronic design and production.

These pictures have important dimension and mount hole positions for 7 and 10 inch LCD metal frames. We uploaded this info in their corresponding web pages.

Our next Help Day is 28th of May

help-153094_960_720

What is help day?

It’s once per month event (usually at the end of the month) where you can come to our place and get help with using our boards.

Sure you can bring stuff not made by us, and we will try to help with it too, but we are most familiar with our own boards and will be of much more help with them.

If you have project using our boards and something doesn’t work as expected, bring it here and we will do our the best to help you.

Our engineers will be available and you can ask questions and get help from the developers.

Or if you plan something but hesitate how to implement it we may help you to pickup the proper boards/sensors for it.

We do not guarantee that we will solve for minutes every problem you have, but at least we will try.

No e-mails – but good old face to face communication. Unfortunately we can offer this just once per month:)

Our Help day for May is on 28th – Saturday, starting from 14.00 o’clock to not rush the people who will come from outside Plovdiv.
