LilyGo vs CYD Cheap Yellow Display for Hacking

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.

Here is my preliminary schematic design to connect the CYD to several modules.  Some IR devies require 5 Volts, so this may be to much of a simplified schematic.

Raspberry Pi Wireless Internet router and Filter with RaspAP

I have built a Raspberry Pi Wireless Internet router and Filter with RaspAP.  I tried a Raspberry Pi model 3 but out of three tries it only worked once. 

But with the Raspberry Pi model 4 came right up and ran.  All you need to connect is power and a ethernet cable for it to work!

In terminal type: curl -sL https://install.raspap.com | bash

Then I answered the many questions as follows:

Create Dir - Y

Complete - Y

Cookies - Y

Control - Y

Congestion - Y

AD Block - Y

Open VPN - N

RestAPI - N

Wireguard - N

VPN Client - N

Reset - Y

Once it is up and running, set the DNS server to 1.0.0.3 and 1.1.1.3 to block the porn sites.

This does a great job of blocking porn, but it also blocks the Ad blocker!  I have not found a solution to this issue yet.  It cannot update but it also delets the database when it cannot update!

Another issue is the built in antenna only has a 20 foot range.  I will be adding an external antenna and will see how that increases the range.

This is a signal strength comparison not netgear router at -34 and the Raspberry pi at -51 dB.
