#ELEKTOR SDR SHIELD PROFESSIONAL#
The audio hardware, motor, and four digit LED display module in the front are all connected to an Arduino with a custom PCB shield, giving the inside of the clock a very clean and professional appearance.Īround the back side has two small push buttons to set the hour and minutes, and a large toggle to control the music and movement. Inspired by the now iconic opening sequence from the HBO series, elements of the 3D printed model spin around while the theme song is played courtesy of a DFPlayer Mini MP3 player module and small 2 watt speaker. Fans have no choice but to entertain themselves while waiting for further tales of adventure from Westeros, which is how we get things like this motorized clock from. Martin will actually get around to writing the final books in the series. The show has ended its run on HBO (not without a certain level of controversy), the planned prequel is still years away, and who knows when George R. However, if you want to graduate to something more practical, try our series on GNU Radio.įor Game of Thrones fans, it’s an awkward time. If you want to learn more about how SDR works, try starting with spreadsheets. Then again, having a programmable signal source on the Arduino isn’t a bad thing and compared to the older version of the board, the new board offers easier breakout for the oscillator signals. That could have led to some interesting possibilities.
#ELEKTOR SDR SHIELD PLUS#
Plus there are many capable CPU and FPGA boards that have Arduino shield-compatible layouts. That’s a shame because some of the 32-bit Arduinos might be able to do some interesting things with the right hardware. The IQ signals appear on the PC’s soundcard via a microphone or line-in jack, and don’t really route to the Arduino. We peeked at the schematic and the shield is more for letting the Arduino control the radio by changing the oscillator frequency rather than performing the SDR functions. There’s also a review video from Elektor about the board in the video, below. There’s also a series of Elektor articles about it.
The board is available alone or as part of a kit that includes a book.
#ELEKTOR SDR SHIELD PC#
The Si5351-based board uses that oscillator IC to shift RF signals down to audio frequencies and then makes it available to the PC to do more processing. If you want an introduction to SDR, Elektor now has an inexpensive RF shield for the Arduino. Software-defined radio or SDR means you get the RF signal to digital as soon as possible and do everything else in software. We always thought RF electronics would be immune to that, but the last decade or two has proven us wrong. Music synthesizers? RC controllers? Most likely, all microcontroller-based now. A project you might once have done with a 555 now probably has a cheap microcontroller in it. Microcontrollers tend to consume other kinds of electronics.
