I am going to try the soldering iron idea with my own design. I plan on using chips with my device. Here is a drawing of my idea and a picture of what it will connect to. I need To know any dangers of using the iron, time to leave on, how much air does the soldering iron technique need, and any other tips you might be able to give me. Also if you see any flaws to my design please let me know. I am not a pro at drawing so I know the drawing is not to scale. The top cover's cylinder will be 4" to match my hose.
