now thats strange. usb cable connected on pc works ok. the camera focuses and takes a photo when i remove it.
but again when using batteries and  the handmade cable and switch, nothing happens no matter what batteries it doesnt respond. 3 or 4.5 volt checked with a powermeter.
The USB cable will actually provide 5V.  But anything over 3V should be fine.  As you sure you are checking the same pins on the USB connector and that the polarity is correct?

yes polarity is correct. but still when try pc usb trick the camera takes a picture but when i apply voltage on black and red cable nothing happens.

i found a comment on the chdk manual that might be the answer. maby not
on page 57
If you are cutting up a commercially-made USB extension cable, then wires 1 and 4 are red and black,
respectively, according to the USB standard. It seems that even cheaply made USB cables follow this
standard. Recent cameras have a combined USB and AV connector, a "splitter" type cable & connector is
required
.

sx130 has a combined usb and av connector

i found a somehow not so expected solution to the problem. i dont know if it is a solution or something that can eventually damage my camera because of short circuit the appropriate usb data connectors.

now the ''solution''.

USB 1.x/2.0 standard pinout Pin    Name    Wire color    Description
1    VBUS    Red (or Orange)    +5 V
2    Dāˆ’    White (or Gold)    Data āˆ’
3    D+    Green    Data +
4    GND    Black (or Blue)    Ground
according to usb standards the above colours/functions polarities are standards. and i thought that since the camera activates remote shutter procedure when connected to pc usb test i thought whats the difference between the test and when i manually aply voltage on red and black cable. so i though it might have to do with the two other cables 2-3 white/green.
i cut the common usb-mini usb cable and there are as common four wires red-black-green and white (in some rare cases yellow)

i bonded (short circuited) the red+green to one cable
i bonded (short circuited) black and white as well to one cable.

now we have 2 cables
the bonded red+green=+ dc polarity
the bonded black+white=- polarity

then i acted exactly like the instructions about the red and black cable and added the switch. but instead of the red cable i used the bonded red+green, same for black i used black+white.
the red/green goes to + of the battery or batteries. the black/white goes to -
the necessary voltage is 4.5V minimum. 3volt doesnt work for me.

dont know what exactly i did. but it works.
i must clarify that this solution is not official. may damage camera. maby not. untested

That update is for cameras with firmware earlier than 1.01c, read the camera's wiki page. CHDK is available for 1.01c, 1.01d, 1.01f.

I have recently installed a new version of CHDK (version 1.3 from today) and gained the ability to write the full sensor data to the DNG file.
What this means exactly (for those who are not up to date on this) is this:
A regular DNG file gives a 4000x3000 image (12.0 megapixel) for the SX130IS.
A full sensor DNG gives a 4080x3048 image *BUT* it has a black frame on all sides, which leaves you with 4032x3024 of usable resolution. (12.192768 megapixels to be exact) or a ~1.6% increase in resolution :)
Now we have access to those few pixels that were unavailable before (it says 12.1 megapixels on the front of the camera, remember). Note - .jpg images from camera are unchanged @ 4000x3000.
This will probably not mean much to most people who wont even bother with it, especially since the cropping is an extra step in your workflow. Only pixel peepers will be able to notice. However, I am not most people and welcome every single extra bit of quality out of the sensor :)
So now at all zoom settings you will have a few extra pixels on each side that are not in the jpg. If you happened to be missing the tiniest (like 16 pixels from top or 12 pixels from side) bit of your image from the frame, you might just get it back by looking in the raw.
All in all, I'm happy with it :)

Thanks for the positive post! Glad to hear you are happy - that's what this project is all about. Canon does a very nice job putting features into their P&S cameras that make 99% of amateur photographers happy. For the 1% left over, there is CHDK.

Help.
i got a SX130IS with 1.01F firmware.
i turned it off, put the 1.01F CHDK on card and turned it on via playback button.
updated firmware (1.0.1.0 -> 1.1.0.0) and CHDK says "Installed"
when i press the shutter i get into camera mode to take pictures and stuff. all fine

but when i restart the camera, its gone.  i have to reinstall it again ?!

This happens every time
