    Default well

    Then we have the problem with the idle current.... 2 resistors in serie between Vdd and Vss is going to drain the battery. I like the idea! but the idle current will be almost half of what the LED uses when it is turned on (sssuming 5V Vdd and 2V voltagedrop over the led)

    I dont have my lab stuff here.. does anyone think the idle current might be lower in the circuit i have attached.. or will smoke come out :-)

    Sure there are many ways to solve the problem by adding more things but I am still hoping this will work...

    or it will be DOOH and an other design.

    Thank you!
