Icarus will scan radio environment using SDR (software defined radio) and display results on map.
The end result is a mobile mapping device using RTL-SDR and WiFi on Kali Linux on Raspberry Pi.
Icarus can be controlled remotely with a cell phone.
My students Tommi, Nikita, Elmo and Aki just started project Icarus. Project ends in May 2021.

You can now write scripts in plain JavaScript. Jquery is mostly not needed for compatiblity.
In 2021, Microsoft desktop and server Windowses only support Internet Explorer 11 or later (Edge). This removes the need for most
compatibility hacks. Firefox and Chrome have followed JavaScript standards mostly from the start.

document.querySelector("h1").innerHTML = "Hello, vanilla JavaScript!"
