We have a lot of unspent BadAss tokens in Borderlands 2. To spend each token, we have to press the "A" button twice - once to select the token and again to allocate the token to a particular buff. SPAMming the "A" button for several hours is boring and fatigueing. A method of pressing the button repeatedly and rapidly for an extended period of time was desired.
We have a similar problem in many other games. For us, this is not a one-time occurence.
There are two videos included with this instructable. A video demonstrating the assembly of the ciruit and a video demonstrating the intended use.
There are more ways to achieve our goal than just this method. Alternative methods will show up as future instructables. I just have some video editing and text drafting to do, first. So, for now, enjoy!
