Something interesting about squishy tacts

[Mario]

They have a resistance of ~100 ohms when pressed lightly and ~30 ohms when pressed hard.

Just keep an eye out for that. It's plenty fine for a game controller, but other projects may not work with it.
I was trying to test some last night, so I had my multimeter in continuity mode (where it beeps when there's a short). It didn't detect any of the buttons being pressed because the resistance is too high.

Just keep that in mind for projects.

just to verify one thing they work with. They make fine replacements for the reset button on the genesis2.

That might actually be useful. Slightly analog buttons, anyone?

I suspect original button pads are the same way. I tested one and it read no continuity.

In the end, I doubt a few ohms is gonna make that huge of a difference, depending on the project, I suppose. Usually you're measuring resistances on terms of kOhms, or even MOhms. I'm sure a logic system will still be able to read it as a high rather than a low.

A game called Okami for the PS2 uses analog buttons. When you press the jump button (X) lightly, Ammy jumps a small distance. Firmly pressing the button makes Ammy jump high and grab wall surfaces.

This would be an interesting replacement for PS2 buttons, but I do not know how much is the resistance of my PS2 buttons. (Darn analog multimeter. )

Ammy.

ps3 replacement buttons? I love zooming in slightly and messing around during cutscenes in mgs4.

Squishy tacts are just membrane pad things in a tact switch like structure. i dismantled one the other day

Mario, did I happen to put you onto this when I messured the Volts comming off these things when attached to a motor?

They will work fine for that.

I don't remember that. I found out when I was testing some on my Sprocket64.

I also noticed this a while ago with a LED flashlight i made. used squishy tact as dim button and regular for full brightness

That's actually pretty cool...
