Dan, what is the worst that could happen? You would get few views and you would have been able to verbally explain to the ether your project, knowledge and thought process. You would have learned the entire process of creating a video, editing for time or content and uploading and processing using YTs system. Do you have to have many views in order to accomplish your goal? If your goal is to do as stated above, would 1 single view accomplish it?, 100?, 1000? 10,000?
When I started my YT channel, my goal was mixed, but I wanted to commit my thoughts and knowledge to posterity so that I could gather my thoughts and experiences in one single place, one single thought or action at a time. My videos are eclectic because I have done so many different things. I have very few views, however, I have not promoted my channel in any way, shape or form. I have not even submitted my channel name here to the YT Channel list on EEVBlog. Not because I don't want my channel to grow, but because I don't need it to grow in order to accomplish my goals. The thoughts and actions that I want are there, I am not done making videos yet and am content that what I create is what I intended.
Also, you do not need much of a camera to create videos. A nice cell phone camera will work just fine as long as you light and frame your work properly and have good audio. Take a look at how different successful YTers frame their videos. For instance, the full body and face view that Dave uses, because quite honestly, he converses a lot and his body language is a crucial part of his content. Also, look at the fully opposite and stark style of Big Clive, where he simply points his camera down at his desk or workbench and talks in the background, rarely making a facial showing. Concise information is all that is needed for a show and tell type video that you are talking about. If you want to throw a little bit of the light side of your personality, let it be natural and un-forced. Otherwise, stick to the subject at hand. Use a conversational voice rather than drone on in monotones.
If, at the end of the day you are unhappy with your product, erase all your video from channel, shut it down and either re-think your approach or abandon the idea altogether, no harm, no foul. If you take the approach that I mention above, you will have very little monetary investment, only time, well spent in my case, because I learned something by making the effort, so far anyways.
As a tip, you will need some video editing software, which Vegas 15 is available for a very small amount, search recent posts on EEVBlog for the link, I think it was $25 US, which is a nice bargain.
