I'm going to assume that you are in Canada (your flag under your username is just black).
I'm going to offer a few simple suggestions. First off, I saw the video a while back where you shocked yourself while doing a tear-down of your soldering iron. In that video, you did a few things that were quite unsafe.
Second, watching you start to test this projector, you are using metal tools (the tweaker) while working on electronics and mains voltages. Not a smart thing to do. Also, I don't know what the meter and/or test leads that you were using are rated for, but when messing around with mains voltages, you should be using decent equipment at best.
Finally, I would suggest ditching the videos until you learn electronics PROPERLY first and get some better equipment for producing videos. The couple of videos that I've watched of yours are... let me put this politely, they're not very good.
Please don't get me wrong. I understand that you are young and interested in this hobby/profession, and in fact I encourage it. However, there is the right/safe way of doing this, and there is the "amateur dangerous" way of doing it. You are on the latter side. I really don't want to see you hurt yourself and I would rather you not put dangerous stuff out on video for others to "learn" from.
That being said, I do have a cheap meter that I bought while traveling to use when I was "in a pinch". Mind you, I was using it for a low voltage hobby project that I was messing with. I didn't use it to measure mains, or anything above 5VDC and way less than 1 amp. At the time, I just needed something simple and not necessarily accurate.
This is the model that it is (I think).
If you want it, pay the shipping cost and it's yours. Save up your money and eventually buy yourself a good quality meter. In the meantime, this should be enough for you to use for LEARNING.
If you don't want it, no big deal. Mostly what I use are my bench meters, and I only pull this one out well.... never.
