Ok, new member, first post. This is my existing gate. I do not want to spend the money for a Mighty Mule gate opener. I have several electric motors I can use. The one thing I imagine I will have to purchase is some type of solar power device(unless I can build that also?). I may have to re-design the gate altogether (don't want to do that, but I can). You may notice the gate itself is from an old awning. Soooooo, ideas????????????
