Viewing the RF Spectrum in Virtual Reality + Augmented Reality EMC Probe

Thank you to Manahiyo for submitting his video which shows his software that allows the RF spectrum to be viewed in virtual reality, using a VR headset and an RTL-SDR. In his setup he currently uses a Oculus Quest 2 VR headset, but it should work with others too. The VR screen allows you to have multiple graphs set up, as well as allowing you to explore a 3D spectrograph from all angles by moving it around via the pointer, or by moving your head.

Manahiyo also has another new VR video on his channel where he uses his RF Watcher software. RF Watcher is his software that allows augmented reality and RF power measurements from an RTL-SDR to be combined. His video demonstrates him using an RTL-SDR and EMC probe, together with RF watcher. As the EMC probe is moved over an RF 'hot spot' on a PCB, red dots are drawn around it in augmented reality.

The programs don't appear to be available to the public yet, but we will follow up with Manahiyo.

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 heatmap.py 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.
