What are all the materials you used to make the one in the video.
I used a old crutch leg for the lever. You will need a drill and a drill set to make a hole in the lever where an end hook of the return spring can be put.
This extension spring is used to return the lever back to its first position. You can use any extension spring that is long enough (at least a inch 1/2) but you want to make sure it strong enough to.
You will also need a propane torch and some sort of pliers to heat and then bend the end hooks on the spring.
If you use a smaller gauge spring and or springs, you shouldn't need a torch to bend the end hooks but you may need to use two of them to get the same force as the bigger gauge spring.
This spring is called "CSC Extension Spring (SP 9617)" it's what I use.

I grabbed some 1/4inch hardware nuts, bolts, washers, and lock washers to bolt the structure down. Also a 3/8 inch bolt, nut, and washer for the pivot of the e-brake. You don't have to do this in standard you can use metric to for anyone that's wondering
For the structure of the e brake I used Zinc Galvanized Plated Slotted Angle iron.

Then you will need a zip tie and some elastic bands, or hair elastics to connect the lever to the analog stick. I may make a video soon on how to make this e-brake what do you guys think?
edit: @ funkthehype you should try this one in the video man, very easy to make and avoids opening up the wheel and voiding your warranty. It also works the same as a G25/27 wired up for a e-brake because your still getting a on/off signal. Me and my dad made one for his G27 it works great!
