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!




All the lecture videos will be uploaded soon at

    The lecture was very good, you made a very good summary of the advantages and disadvantages of LoRa and LoRaWAN. I am also awaiting the release of the OSHW devices you mentioned.

    I learned how to solder at Olimex soldering workshop during FOSDEM a few years ago. Back then Tsvetan and Mitko Gamishev taught me with Olimex FOSDEM-85 soldering kit. It was awesome that this year at OpenFest my friends and I were able to pass the soldering knowledge, passion and fun to others 🙂
