Setup OLIMEXINO-STM32 to work with Arduino IDE

arduinostm32

Arduino IDE support Cortex-M ARM architecture and although STM32 is not “officially” included stm32duino.com¬†has all the resources to add support for STM32 boards in Arduino.

This forum post explains what should be done step by step to setup and use OLIMEXINO-STM32 board with Arduino IDE.

OpenFest 2018, LoRa technology and OSHW

First OpenFest was back in 2003, so this year this open source technology event had 15 years anniversary! As always it was nice place to see and talk to interesting people.

Vasil Kolev opened with nice retrospection on how the event started, the challenges to make it (OpenFest is one of the few events which builds all infrastructure, video, networking etc by the organizers and do not use external service providers) and how it evolved in the years to become the most popular open source event in Bulgaria.

Since 2011 Olimex was making traditional soldering workshop on every OpenFest. Lot of people held soldering iron for a very first time at these workshops, many of them got interested and continued with hardware. One of these guys is Leon Anavi, who got very commited to Open Source Hardware and start releasing his own boards! This year Leon, who is also the major motor behind Tuxcon conference in Plovdiv made the Soldering Workshop at Openfest!

The biggest FOSS/OSHW event in Bulgaria – Open Fest is 3-4 of November

Our favorite Open Source event – OpenFest is approaching. Every time I go there I do wonder how small Bulgaria attracts so many people there – thousands of people meet together. Probably the answer is that IT is developing very well and lot of people in Bulgaria work in IT industry.

I’m really pleased to announce that my proposal to talk about LoRa/TTN/LoRaWAN myths, possibilities, applications and limitations is approved! I will try to compare all popular LPWAN solutions, why LoRa is leading there (hint: open source ūüėČ ) and how you can calculate your power requirements, link budged etc to make sure your application will work with years on battery.

eduArdu is new Open Source Hardware educational board targeting kid’s digital education

eduArdu

Few weeks ago we got contacted by Digital Kidz an non for profit foundation which goals are to support digital literacy and innovative education in the schools. They needed hardware board, which to be easy to use and to allow entry level programming with Scratch and Arduino for beginners. They were ready to pay for the development, but we liked the idea and decided to design one such board for free and release it as Open Source Hardware.

The result is here:

eduArdu-explained

The design is based on ATmega32U4 which is easily programmable with Arduino IDE. We named it “eduArdu” as this is educational board programmable with Arduino.

eduArdu has these features:

  • USB connector for programming and power supply
  • red LED matrix 8×8 which allow text and small image animations
  • X-Y Joystick with push button for navigation
  • Microphone for Audio sensing and interactions
  • Speaker for Audio output
  • Light sensor with LDR
  • Digital temperature sensor
  • RGB LED
  • Status LED
  • IR remote control LED and receiver to talk to other boards, TVs, Air conditioners, etc.
  • PIR motion detector up to 6 meter range
  • UltraSound distance measurement sensor
  • Two SERVO motor connectors (to build easily two wheel robot car)
  • LiPo charger so the whole board may work on LiPO power
  • 6 Makey-Makey style buttons
  • UEXT connector for additional modules

The board is shaped like Game console. The first prototypes will be ready in 2 weeks.

Target sale price is EUR 15.00
