Hi, I made the Etch-A-SDR. Found this thread after seeing the stars on the Github project jump (Thanks HN!). The hardware used is: - Acrylic sheet - Odroid C1 (There are more powerful Odroids now, either the C2 [0] or XU4 [1]) - RTL-SDR - GY-521 6DOF - Teensy 3.1 - Rotary Encoders (adafruit) - Push buttons (adafruit) - 10.1" TFT screen with speakers (adafruit) - Ethernet / USB bulkheads (adafruit) - MCX to SMA bulkhead (ebay) - misc parts ( screws, stand-offs, etc from home depot) - Knobs from a real Etch-a-Sketch I presented this at the monthly Cyberspectrum SDR Meetup [2] in San Francisco, the slides, which include pictures of inside the Etch-A-SDR, and an overview of the hardware/software can be seen here [3], and a live stream recording here [4]. If you're just getting started with SDR, I would suggest setting it up on regular computer vs starting with running it on an ARM type board, SDR is very resource hungry, and runs better on a normal machine. There is a big community over at the r/rtlsdr [5] subreddit. SDR is a lot of fun, and opens up the huge world of RF, and it is very inexpensive to get started.
