    Congratulations to shabaz for PlanetCatcher: Building a World-Band Radio Receiver You Helped Out Judging and Preferred Prizes Go to other Members So You are the Winner of the Heart Trophy and also win some free swag!

     

     

    The theme RF (Radio Frequency) competition involved projects that involved or explored RF including circuits, antennas, SDR (Software Defined Radio), ham radio, modulation/demodulation, RADAR (acronym for Radio Detection And Ranging), and more!  Projects involving RF are broad in scope and could include robots, data acquisition projects, data transfer, automation, remote control, wireless sensor networks, cellular IoT, health, object detection, and more!  It was great to see some outstanding project contributions from some of longtime members such as lui_gough , kmikemoo , and gecoz.  As well as a couple of really great projects from eivholt who did some great projects involving LoRaWAN.  Also, shabaz who was a strong contender for the Grand Prize with his PlanetCatcher: Building a World-Band Radio Receiver chose to submit his prize as a gift rather than an entry.  Instead he helped out with the judging and will be the first person of the new year to receive a Heart Trophy for showing heart.  The first place winners of this competition were all worthy winners as was any of the members listed as runner ups.  The three first place winners will have a chance to gift those members with a Raspberry Pi 3 Kit in a box.

    The Winners

    The Grand Prize

     

    Xmas Audiovisual Show by neuromodulator

     

    Community Member Scoring:

     

    Grand Prize: 8 Points, First Place: 1 Point, Total Points:  9 Points

     

    Xmas Audiovisual Show

     

    "Xmas Audiovisual Show was a very impressive combination of RF and FPGA and it was provided with copious documentation. I like these 'sledgehammer to crack a nut' projects where they demonstrate the underlying science in an unusual context." - Community Member Judge

    "This was a great project as it generated the RF directly from an FPGA, and that in itself is not easy, but also explained very clearly the steps involved. I really learnt a lot from the great writeup blog, photos and videos. I plan to revisit this blog to copy and try and replicate it myself." - Community Member Judge

     

    "It was great to see a transmitter project implementation in FPGA. The results were very good too!" - Community Member Judge

    "Xmas Audiovisual show - Really like the use of FPGA's here." - Community Member Judge

    What's Happening Now

     

    The end of the year is a time for stepping back and taking a look back, so you can begin looking forward to the new year. One thing we're going to do this year, that we haven't done in the past is hand out some individual awards.  Find out who the Decider, Founder, and Influencer of the year is in Project14 | The 2019 Year in Review: Decider, Founder, and Influencer of the Year! and vote for your project of the year in Project14 | The 2019 Year in Review: What Is Your Project of the Year?

     

    Year In Review
    Project14 | The 2019 Year in Review: Decider, Founder, and Influencer of the Year! Project14 | The 2019 Year in Review: What Is Your Project of the Year?

     

     

    There's always stuff going on in the community and the best ideas always come from you.  Suggest your idea in the Monthly Poll,  and vote on the themes you want to do projects on. Build projects projects that involve infrasound, audible sound, ultrasound, amplifiers, piezoelectric material, spectrum analyzers, and more in the Acoustics  competition. Your project can be anything involving sound or using a transducer for converting one form of energy into another. In an electroacoustic context, a transducer converts sound energy into electrical energy (or vice versa). Your project can involve electroacoustic transducers that convert a sound wave to some form of electric signal such as loudspeakers, microphones, particle velocity sensors, hydrophones and sonar projectors. The most widely used transduction principles are electromagnetism, electrostatics and piezoelectricity.
