Yup. My point in providing the drawing is to help those people looking to jump into this hobby but are a little new or unsure how to construct devices such as this. I've seen a few people post on the site who expressed a desire to delve into the more technical aspects of the hobby but lacked the technical training or know-how when it comes to these sorts of things. Hopefully this will help one (or more than one) person along the trail and encourage them to "peel back the curtain" so to speak. We live in a physical world in which systems and devices work for very specific reasons; when we can get to the root of WHY and HOW they work, that's when the real fun begins.
