depends on how much porn you have...
personally id been 5 terabytes...
I win because I have the most fun in life...

satelite images... I will already have about half of it filled before I get the computer.

I know I am 13 days late, have you filled up the 2 terabytes yet? :->

No, purchasing is slow.... while my project leader is itching to get my old system, only the CASE has been received!!

does anyone know a way to control more than 8 leds or whatever with the output ports??

Yes. Use shifting (Flip-Flops). You will need to add an external power-supply, though, but that should not be much of a problem. I believe there actually is an article on that topic just here on CP.
Otherwise, search for "Blinkenlights" and explore from there. Blinkenlights is a light matrix display controlled by a PC. There are some implementations using LEDs instead of the floodlights, so you might even find a working solution for your project. I assume its about creating a marquee of some sort

A simpler solution would be to utilize the control port as well as the data port.
|

is it possible?? please rbuchana, tell me how??!!
|

Well how are you writing the parallel port? Either using Inpout32.dll or _inp/_outp depending on your operating system. Either way your writing to an address (maybe 0x378). The control port is 0x02 more than the parallel port address.
So if your parallel port address is 0x378 then...
status address: 0x379,
control address: 0x37A.
Utilizing the control port will give you 4 extra output ports.
FYI some of the control ports are hardware inverted.
If you need more than 12 outputs, you may need to do like previously suggested and add some extra external logic.

thank you rbuchana , u're gr8

thanx Sebastian!i'll look for that "Blinkenlights". actually it's not a marquee that im doing, it's about creating a digital counter on a 7-segment display that i cant light more than one full digit "8".

hello guys, does anyone know where to get an affordable volumetric 3D projector that can display floating holograms in the air??
check this cool sample
ps. u need google video player to view the sample.

Hi ¤ Muammar ¤,
I'd bet if you Googled, one of the sponsored links would be selling what you're after.

hi everyone, i have two relays that read as:
(RadioShack)
Coil rating of 5VDC
90 mA
55 ohms
SPDT 1A at 125VAC
(FANGKE)
10A/28VDC
5A/220VAC
DC 5V
please advice why cant i trigger them using the 5v from the LPT port
thanx in advance.

Have you used a multimeter to confirm you're providing the amount of current and voltage that the relay requires to switch over? IIRC the LPT port is a relatively low power interface, it might not be able to provide sufficient power to work the relay.

Rules of thumb should not be taken for the whole hand.

|

you're right dan! i thought LPT is always providing 5v. here's what i got
3.34 DCV
46 mA
i just found this relay on radio shack, do you think it will work with the amount of current i have??
Maximum switching power of 10 (Watt/VA)
Maximum switching voltage of 60 VDC, 120VAC
Maximum switching current of 0.5 A
Maximum initial contact resistance of 150m ohms
thank you dan!

The LPT port can't produce 90mA at 5V. The
spec[^] requires only 14mA drive capacity at 2.4V. You must add a driver circuit between the relay coil and the printer port.

thank you mark, but that was so sophisticated for me to understand cuz i've nothing to do with electronics and i just wanted to trigger a relay using the power from LPT port, can you please suggest another relay that will trigger directly without making any circuit??
thank you mark!

The LPT port isn't rated to deliver that much current, you will need a driver circuit plus the voltage from the LPT port under higher current isn't 5 volts.

Hi,
Does anyone know if there are any adapters available to install a PCI-X 64bit (133MHz) card on a PCIex8 slot which runs at x4 bus speed?? I know that there are interchangeable adapters available to install boards of PCIe (x1,x2,x4,x8,x16). But since a PCI-X 64bit 133MHz runs at the same speed as PCIex4 speed, I wonder if there are any adapters of this kind...
