I am an old tube guy, haven't played with electronics in a long time. There are a few parts I can guess but also a few I haven't a clue. In the attached picture what are the parts in the top left corner(not the SPST). An amazon link would be ideal, otherwise some words I can search. In addition, I have no idea what a '3-pin female Dupont jack' is, what it goes into, and 100% clueless what a 2.1mm chassis mount power jack with internal cutoff switch is. I assume I also need whatever plugs into that jack.

HELP!

I don't know what happened, but I did not see the video on building this project. I thought I did, but when I clicked on the in blog video I saw that I had not watched it. My apologies for wasting time. I will now study the video in depth and hopefully it will answer my questions.

Here is a 3 pin female dupont connector. These happen to be attached to a servo.

@sj_h1 OH, I was thinking the dupont connector was a lot more than just a jumper. Does that 2.1 jack have the internal cut off?  If it does, now I need to find a supplier in Canada. Thanks for the pointers. A lot has changed in 60 years, I am in massive catch up mode.

@ronalex4203 From the Q&A section of the link 

How do I wire these?

Best Answer: This is a 3-wire connector that can be used as a simple 2-conductor jack, or for more involved AC adapter/battery applications. View rear of connector with contact "triangle" pointing up. Left contact (1) is tip. Top contact (2) is ground/shell. Right contact (3) is switched.

Use 1 and 2 to deliver power from plug, i.e., AC adapter or external battery pack. Terminal 3 contacts terminal 2 internally until a plug is inserted. Can be used to disconnect an internal battery (-) terminal from ground when plug is inserted.

@jrpchef Check the YT video, and the video in the blog Then the step by step instructions in the blog should clear it up. I too am new to all this but after much assistance form a few guys here, most notably @will I now feel confident to proceed once all the parts are here.

@jrpchef Understood, me too. The circuit diagrams are in the blog, and the plan is the blog narrative. For me what is missing is the amazon links to the parts but I have about 10 trucks oin their way starting today so hopefully I can get it to work.

What helped me and might help you is to look at this project as two projects. The power box is usable by itself going forward, it has battery power and external power ability putting out either 3.3V and/or 5V at the binder posts from up to 12VDC input. Perfect for me because I live in an RV with 7.2kWh of DC. The dupont power connector is a dedicated supply for the ESP32 camera. Maybe that will help you too
