Webcam Mod wiring

Just finished my mod according to this design - works great, and cheap too!

Well seen as my request for assistance fell on deaf ears I spent the last week phoning round and found someone who is capable of soldering small stuff so hopefully my cam will be back up and running next week .

sorry sailor missed your post. hopefully your all sorted

Not a problem ta, did get the work done in the end, I just wanted to keep it within SGL and pay someone here .

Is there a "proper" circuit diagram / schematic for this transistor only mod please? For some reason I can't get my head around it looking at these vero boards...

So I finally found a SPC900NC and it's in Phoenix so I just have to wait for it to be mailed to the San Francisco area. While Im waiting for it to arrive I have a few questions about the mod and I'll probably have more later on.

1.) With the dead bug method can the 4066 chip be substituted with another chip? I would like to buy everything from a local electronic store.

2.) Now with the mod that deals with a PCB board. Can the PCB be copperless and if so do the cuts need to be made?*

3.) I see all the talk of if you don't have a parallel port on you laptop you have to go with a serial mod but wouldn't a parallel USB converted work.*

Yes, there are other FET switch chips.

2.) Now with the mod that deals with a PCB board. Can the PCB be copperless and if so do the cuts need to be made?*

Yes, poke the wires through the holes and solder together on the other side. With no copper there's nothing to cut. Or use a breadboard where you just plug component wires into little sockets.

3.) I see all the talk of if you don't have a parallel port on you laptop you have to go with a serial mod but wouldn't a parallel USB converted work.*

For use with the transistor circuit, anything that will produce two data outputs will work (if you use the right drivers/software). But USB to RS232 adapters are readily available and cheap.

is this a worker? malc where are you lol

.

prob not conventional but its on a very small footprint would easily fit in the cam case

.

is there a way to wire this for parallel port?
