Great sketch Amerinah! I couldn't agree with you more about all the help folks on this site provide. All you folks, you ARE the best, amazingly willing to share your knowledge, experience and expertise! Sincerely, thank you.
Now to the sketch. I am not an engineer, but I work with them every day. Interesting people, you engineers. Most every thing you sketch or draw looks awesome on paper. The real test is how it works in the field, under actual conditions that can't always be replicated in the office or on paper. Any argument with that, just think about the last time you tried to work under the hood of your car. For many, many years I was one of the guys who tried to build or implement what the engineers had designed. Sometimes it worked, many times......well! I agree with a lot of the comments here, start out simple and work your way up, otherwise you will be trying to straighten out some messes even a NASA scientist couldn't figure out. I really like the sketch though. Honest. And I love your enthusiasm even more. After your field testing please keep us posted as to what worked and what didn't.
I used to tell engineers all the time- "You can draw an ****, but I have to make it s**t".
