Re: How to reduce Signal Length if possible?


Hello I have been working on a little project just out of pure
curiosity and I have completed my project about 90%, but I have run
into a road block and I would appreciate some help if anyone is willing
to do so. Here is the link for the project I am working on, something
nifty I found on the web and I had 10 bucks and some time to spare, so
I tried it:

The fellow who wrote this article never mentioned how to remedy the
problem I have been having by the time you finish the modification.
However, instead of complicating things by explaining to you the whole
procedure I went through I will describe a scenario with a Thevenin
Equivalent Circuit.

MY PROBLEM:

I have a (V-Thevenin) DC voltage source of +3.3V and for arguments
sake, a resistance (R-Thevenin) of 10 ohms. My voltage source connects
to a switch, this is not a traditional switch that only has two
positions, it is a toggle switch. To elaborate, this switch simply
sends a signal to the circuit board of my Xbox and the Xbox will turn
on or off depending on the duration of the press (holding down the
toggle button).

If you visited the provided link above, you know that a wireless RF
controlled doorbell component is used to ground the switch remotely and
the result is the Xbox turns on, which of course is the desired result.
The duration of the chime for a single "DING" is approximately 6
seconds long. This is bad. The power switch on the Xbox, when held for
6 seconds: Turns the Xbox On, then Off, On again, Off again and finally
it stays On. This is absolutely horrendous for the circuitry for fairly
obvious reasons.

So what I have been trying to figure out is how in the heck do I reduce
the duration of that signal to a mere 0.5 to 1.0 seconds max?

I have tried using incredibly small capacitors thinking that it would
take a bit to charge and that there would be a small enough trickle
effect for it to turn on, but that idea didn't work too well. A
resistor is obviously not the right idea. And I am stuck, I do not know
of a component that I could use to reduce the signal duration. Any
ideas at all are appreciated! If you feel the urge to tell me to get up
and turn on and off my Xbox, please don't post, I am doing this out of
interest.

XBox switch doesn't work like that- you have interference with the ding transmission or something is broken.
