Back in 2020 someone told me the covid19 tests were radioactive. I pulled out my Geiger counter and proved that was not true. Now I am hearing the Covid19 vax gives people a Bluetooth/RFID/MAC address. So I decided to venture into hacking to find out if that is true.
Right away I had a second use for these devices. I am setting up a Raspberry Pi RaspAP filtered router. I need to compare signal strength between the RaspAP and Netgear router. The objective is to add an antenna to the RaspAP and see how the two compare in signal strength.
I bought a LilyGo and a CYD to compare the two. The CYD lacks many sensors and the LilyGo has a screen so small that you need a magnifying glass to read it.
So I decided to buy and add the additional sensors to the CYD device. Now there is a guy who has added several modules to a CYD using around 12 switches to select between the modules. I am hoping to simplify the design with less modules, three position switches, and 3D print a case for it.
