PS3 Style Buttons

oublie · 29th July 2009, 02:05 PM

Hi folks anyone know how the buttons on the ps3 work. They are sort of embedded into the case so that there are not moving parts or holes in the case. They seem to be touch sensitive or something. I'd like to try using a similar idea with a project but have no idea what they are.

Thanks.

They're probably capacitive sensors.

Thanks Star any idea where i'd purchase these for as as power on/off - im in europe.

Stores like Farnell will have them, just as long as you realise they require a microcontroller to use. Not as simple as just wiring them up.

Resistive touch switches are easier to DIY - you can make them with just a couple of NOT gates.

I've never seen a PS3 in real life. But if you want finger proximity, you could use an LED/photodiode combination beneath some dark tinted perpex.

If you want a simple solution...

Look for QT110 chip.

It's a single touch sensitive switch IC.

I think Quantum was bought by Atmel, because I can only find the QT110 on Atmel website now :S

Anyway, there is planty of information about QT110 and similar on the web.

Eg : http://www.lextronic.fr/P1776-capteu...tif-qt110.html (in French, but the schematic and picture are quite self explaining)
