Congratulations to   for Arduino MKR GSM and SemTech LoRa Example: LoRa Message to SMS ,  for NFC Data Exfiltrator: QRSS on the NXP EXPLORE-NFC feat. Raspberry Pi,  for Star WarsRegistered R2D2 Uses the Force with XBee RF Virtual Wires  and   for PDTect_RF Partial Discharge Detector !  You are the runners up and you win free swag!

 

Congratulations to 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 , , and .  As well as a couple of really great projects from who did some great projects involving LoRaWAN.  Also, 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 Grand Prize

 

Xmas Audiovisual Show by

 

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

"Lots of experiments with the aim of seeing how different antennas for Ham radio can perform. Nice to see the practical approach even in winter outside!" - Community Member Judge

 

 

"Mike's project aligned exactly with what I thought this RF Project14 would involve. He blogs several times over the period, each time building and taking us further on a journey of learning - I didn't even have to stepoutside as Mike did into the cold weather!" - Community Member Judge

"Excellent experiments with a VNA, his project shows that anyone can start exploring antennas on a budget." - Community Member Judge

 

 

"This project blog taught me a great deal about RF measurements and also showed me the availability of some low-cost but effective test equipment. Fabio's series of blogs ofver the competition period were a real joy to see and read." - Community Member Judge

"Nicely documented and educational series using hobbyist accessible equipment"  - Community Member Judge

"Nice exploration of how NFC can transmit unexpected distances." - Community Member Judge

 

 

"This was first on my reading list but the quality of Gough's video and the information he got across in this project kept this project high on my list to choose at the end. One of my scoring criteria was 'would I like to replicate this project' and for that I gave Gough 3/3 points." - Community Member Judge

"Very interesting and educational submission full of things I didn't know.  I went back and read it twice.  Great video." - 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?

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.

  • Project to design RF friendly Switching Converters by  :

    "A nice start into exploration of RF from DC-DC power supplies. Looking forward to seeing it develop." - Community Member Judges

    Ah, the judges did seem to like my idea.

    The next step is to finish a few details of the PCB design, send off for PCBs and parts, and then tinker with the values to see what produces the least EMI or disruption to say FM radio.

     

    However, without the Spectrum Analyzer, nor an Oscilloscope or even a parts budget, it's impossible for me to go much further.

    It's unrealistic for the community to contribute nothing towards my project, but still expect me to continue with it.

     

    I can't in good faith produce something I plan to sell, without any way to confirm that it actually does what it claims.
