I having few problems with this.
So i have messed around a bit with compiling parallel port programs trying to set ports to 1 and 0. But not quite sure if its working.
1. I put multimeter on one of the top pins and on one of the groud pins and 5.5v are coming out of it. Should this be the...
Ok so i plugged my multi meeter into the well and it seams to have bowen the fuse to my house.
2 questions:
1. Why did this happen
2. how do i stop this happening again.
Thanks
Yes sweet found this
**broken link removed**
Type Case VCEO VCBO VEBO IC PTOT hFE FT
BC547c TO92a 45 50 6 100 500 520 300
And what should i use to step down from 5v to 3.5vs?
Yes exactly what i want to do there.
Can you help me with this?
I know i need some transisters (but not sure what type) and need resisters to step down from 5v to 3.5v
Thanks for that info
And now another questions how do figure out what transistor i need for the following?
Also if the parallel port gives out 5 volts and my control at the moment when circuit when closed passes 3.5 volts.
What are the numbers that i should be looking for?
Hey i am looking for some info.
Am working on connecting parallel port to a remote control.
I have figured out that its a transistor that i need to use for this.
But when i went to buy some transistors there are so so many times

Change power head
i ended up just striping back the head because solder would not attach to the pins. and just attched the solver to the outside and the white cable to the center pin.
I have this but want to change the head.
From this
**broken link removed**
to this but not sure where to connect the silver cable or where the white cable goes? and what side of it.
**broken link removed**
+ syblem on the side there one is fatter than the other
Can anyone help?
Thanks
