![]() ![]() Unfortunately, winding your own Tesla coil is kind of a hassle. ![]() Sound effects not withstanding, it’s Tesla coil all the way, no question. Even then, it’s kind of unfair advantage because you know people only want a Jacob’s Ladder for that awesome sound it makes. There’s also a review video from Elektor about the board in the video, below.Ĭontinue reading “RF Shield Turns Arduino (And PC) Into Shortwave Radio” → Posted in Arduino Hacks, Radio Hacks Tagged elektor, sdr, shield, software-defined radioĪ Tesla coil easily makes it to the top spot on our list of “Mad Scientist” equipment we want for the lab, second only to maybe a Jacob’s Ladder. 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. 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. ![]()
