I bought a new 3D printer again this year a Creality Ender 3 V3 SE

I bought a new 3D printer again this year. It is a "refurbished" Creality Ender 3 V3 SE.  Last year I bought  Ender V2 and upgraded it with a quiet motherboard.  I had purchased a CR Touch Auto Leveling kit for it but did not install it. Now I know how important the auto leveler is!  I had also gone through three build plates on the old printer and then bought a TRONYX glass build plate. The TRONYX glass build plate is about 1/2 inch too small but worked GREAT!

This is a close up of the new printer, it looks more refined or finished than the old one.

This picture compares the old printer to the new printer.

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.  The ad blocker 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 to a Netgear router at -34 and the Raspberry pi at -51 dB.
