FOSSASIA Summit 2018 Schedule – March 22-25

FOSDEM is the “Free & Open Source Software Developers’ European Meeting” takes place the first week-end of February every year in Brussels, Belgium. It turns out there’s an event in Asia called FOSSASIA Summit that’s about to take place in Singapore on March 22-25. There are some differences however, as while FOSDEM is entirely free to attend, FOSSASIA requires to pay an entry fee to attend talks, although there are free tickets to access the exhibition hall and career fair. There are also less sessions as in FOSDEM, but still twelve different tracks with: Artificial Intelligence Blockchain Cloud, Container, DevOps Cybersecurity Database Kernel & Platform Open Data, Internet Society, Community Open Design, IoT, Hardware, Imaging Open Event Solutions Open Source in Business Science Tech Web and Mobile Since the event is spread out over four days, it should be easier to attend the specific sessions you are interested in. I’ve […]

Building a Compact Digital TV Transmitter with Raspberry Pi Zero, Pi Camera, and LimeSDR Mini USB SDR Board

There are few affordable standalone systems that allow you to transmit video over the air, and back in 2016, I had the chance to check out V-Bridge Muses-β MPEG-2/-4 encoder and DTV modular taking HDMI or composite video input. It was easy to use and worked fine, but it would still cost close to $600, and might have been a little smaller. Evariste Okcestbon has now created its own digital TV transmitter prototype, combining LimeSDR Mini USB SDR board with Raspberry Pi Zero board, and instead of supporting external input from HDMI or AV ports, he used an official Pi camera for video, and was able to transmit the video over a 1.2 GHz connection to a Raspberry Pi 2 with an RTL-SDR dongle, with the Pi 2 board also taking care of displaying the video signal. The full flow of transmission can be summarized as follows: Video from […]

GR-LoRa is a Reverse-Engineered Open Source Implementation of LoRa PHY

LPWAN standards such as LoRa or Sigfox allow you to transmit data over long distance, at ultra low power (up to 10 years on a AA battery), and for free if your use your own network (P2P or gateway), or a few dollars per years if you go through a network provider. The low cost is possible since those standards rely on 900 MHz ISM bands, meaning nobody has to pay millions of dollars to the government to obtain a license fee. Matt Knight looked at LoRa, and while Level 2 and 3 of the protocol (LoRaWan) has public documentation, Level 1 (LoRa PHY) is proprietary and the standard is proprietary. So he decided to reverse-engineer LoRa PHY using Microchip RN2903 based LoRa Technology Mote and Ettus B210 USB software defined radio, and software packages and tools such as Python and GNU Radio to successfully deliver GR-LoRa open source “GNU Radio […]
