Next weekend in Sofia will be held the biggest event for Free/Open Source technologies in Bulgaria – OpenFest which is run every year since 2003.
Olimex is approved for talk and workshop yay!
The lecture is in Saturday at 17.00 o’clock and we will show what we have been working mainly this year:
“Physical computing and IoT with Open Source Software and Hardware”.
We will demonstrate how easy is to connect physical objects to Internet with our new ESP8266 boards, and our plug and play firmware which recognizes the UEXT modules connected to ESP8266 like: electricity metering, LED displays, Fingerprint sensors, door locks, relays, buttons. etc. We will shop how to display Twitter messages on LED matrix display, how to make door lock with fingerprint sensor, how to implement DO button for IFTTT directly with ESP8266 by secure connection with 2048bit encryption, and how to connect and switch loads and measure what energy they consume.
Specially for Open Fest we made our new WiFi enabled LED 8×8 badge. It contains ESP8266 and can be programmed to do lot of stuff, like to display all tweets with hashtag #openfest2015 or to display what are the lectures which run now and in which rooms by connecting to Open Fest program web page and extracting the necessary info.
Needless to say WiFi Badge is OSHW and all software project sources will be on GitHub (sorry still work on the software and can’t upload yet, we will do this early next week keeping the good developer’s traditions everything to be complete and debugged in the last minute 😉 ).
As you can see all ESP8266 GPIOs are exposed on this badge so it is good also for development board, power supply is done with single 1.5V AA battery only!
The workshop will be about SMD component soldering, we will bring some Binary Watch Kits with us and teach you how to solder your own Binary Watch. These who already have been at TuxCon do remember these watches:
Looking forward to see you there 🙂
