I’m looking to mod one of my GC controllers to help me get better at short hopping in Brawl/project M. What I think I need is when the button is pressed it triggers and then stops after 5 or less frames, about .3 seconds I think, regardless of whether I’m still holding the button or not. My initial idea is to have a 555 circuit hooked up to a button like z, so the circuit completes, triggering the timer and the timer will start to cycle after ~.3 seconds breaking the circuit thus registering as me letting go of the button, maybe add an external potentiometer to adjusting for characters with longer or shorter jumps.

Am I over thinking this? This is just the first idea I thought up. Basic smash rules ban short hop modded controllers so it must have been a problem at some point. but I have never seen or heard of anyone actually having one so I can’t find much documentation on the matter.

thanks for any input anyone has to offer.

If you’re planning to get competitive at Smash, bear in mind that it is illegal to do any internal mods to your GC controller:

I’m absolutely aware of that, it would be a teaching aid like as I said.

Oh, okay, so long as you were aware of that.

I tried looking through smashboards and came up dry, but I’m sure the mad scientists here will have an answer.

I also managed to gloss over where you said you were aware of all this. My fail.

Yeah the only mods I seen get a pass on Gamecube controllers are those that increase accessibility to the disabled.
Even then some tourneys will still complain.

I’d say your initial design is fine, but I think just grinding out the execution would be better for you, otherwise you won’t actually learn it properly.
