I need to make two springs to pop open the lid of my project box when I energise a relay.
No matter how hard I tried, I cannot make a spring as shown in the diagram. The one I made is too "tall" as shown at the bottom.
What is the secret of make such spring?
Edited: Apparantly I need to use some tools(instead of just winding the wire by hand on a drill bit) in order to coil the wire. The answer is in the following webpage.
