Radio Spectrum Analysis in Virtual Reality with an RTL-SDR and Google Cardboard

Thank you to José Carlos Rueda for submitting his project called “a-radio: a web virtual reality radio power spectrum analyzer”. The idea behind the project is to first use an RTL-SDR together with rtl_power and to generate a heatmap image of the RF spectrum. This image is then projected into a 3D 360 degree view and hosted on a web server via José’s script for the a-frame VR web framework, allowing the heatmap to be viewed with a virtual reality (VR) smartphone headset. José’ recommends using a cheap VR headset like Google Cardboard which can be used with your Android smartphone. 

José notes that the project is just a proof of concept, but he hopes to inspire future work around the combination of RF and VR.
