Serial Cable powered flashlight

V4mpiro · 23-July-03, 04:38 PM

I am wanting to make a flashlight like the one seen here http://www.pcapex.com/modules.php?s=...ticle&artid=79 , but I dont want to use a valuable USB port so i want to make one out of a serial port cable. Is this feasable? Are there and steps that I should change or skip from the usb powered flashlight?

Serial cable, as I remember, probably won't have the power. You'll probably want to go USB.

You never see a serial optical mouse for a reason...

BLAST... well im glad that i asked befor i started butchering. So you are telling me that last night B Boy was wrong in telling me that serial cables carry 5 volts of power?

5 volts but they dont have enough amps. USB has 5 volts with tons of amps to spare. I believe its 5 volts @ 5 amps if you have a USB hub, otherwise 250mA or something like that. Serial cables only provide 5 volts @ a mere 50-250mA I beleive. A 5volt LED would run off of a serial port but thats about it. For an actual light you'd have to use a USB port.

OK....I have my Logitech MX300 optical using the serial adapter and it works just fine. I plugged it into a USB slot and it didn't make any difference. So, what difference does it make?

B-boy, you never see serial mice anymore. They just aren't needed

Unless you own an olllllllllld computer like my school does. Half the computers in my school use Serial BALL mice, they suckass and the computers are slow, but they can do word and have a laggy mouse pointer in Windows 98.

Why not try a PS/2 port? What type of amps do those provide?

yeah a ps/2 port alot of external hard drives use that for power. but if you could use the serial port for a flashlight i wouldnt have another cable comeing out of my comp to power my LCD.
