Ya, how's it happening.? By this, we can do touch sensor I think...
you might need some other circuits if u want build a touch sensor because the output will turn off when you take your finger off it.

hi,
Try this very simple layout, as I said earlier the 555 maybe faulty.!
eric, i built the circuit you drew,but why is the LED keep staying ON? i mean it blinks but it keep staying and turns off for a second and on again.., i thought it would stay off and turn on after a limited time(as capacitor value).. U got what i meant?

I think I got answer for Ziddik, Here is the calculation, The output's High and Low in second can be calculated from here..

Am I right Eric?
