Damn Mine is dead
Killed my websurfer

New MessageDamn Mine is dead (modified 0 times) FoOL
ERRR!! I am a happy hardware hacker. I make things run that all my freinds and peers would give up on. I am going to give up on my WebSurfer, I killed it and I have no idea how to fix it.

Let's start with some history. I got a WSP the day they where found to be 50 bucks, took it home and dove right in. Got my isa IDE contorller from a junk box and was booting into win98 in under 20 min. I had the harddrive connected to an old power supply that was sitting next to the WSP. OK, this all was fine and dandy but I wanted the drive INSIDE the case. So the hacking starts.

Cut me a hdd power cable from an old pwr supply and shoved it into the power cable in the mobo. Easy drive spins and win98 boots. I am thinking right on the power supply can handle it. I dig around and find a 2.5 ==> 3.5 drive cable connector and a 2.5gb 2.5 drive. use the cable out the back of the connector to test. It works. Great now 2.5gb is way to small so I need to use the 10bg 3.5 I have. Since the IDE card I installed was about 1 3/4 inch wide I had the room over the mobo to mount the fullsixe drive. Off to the metal shop. Have a buddy of mine make a mount plate and I install it. Great all works fine. I run it for a few days no problems.

I get home from work last Friday night itching to do some hacking... I decide that it would be a cool thing to pull the power cables from being shoved into the mobo power connector and connect the drive to the 12v power lead next to the power supply. I test this lead by switching the fan cable to it and boot. All is good. I switch it back and hit it with a voltmeter, I am golden here, it's what I am looking for. So I grab my sodering iron and find me an old fan to cut the line off of. Soder the two together and install the cable into the mobo and the hdd. hit the power and I get nothing. I smell smoke. I see smoke. I yank the power cord from the wall.

At this point I am wondering if I am an idiot and mixed my ground and hot wires, I take a look and nope nothing wrong. So I grab my other hhd power cable and shove it back in the mobo power connector. Swap the drive power source and hit the power button. Nothing.... damn forgot to plug it back in. Plug the damn thing back in and now I get a great screen of nothing. it will not post. IT IS DEAD and I have no clue how to even start debuging this, hey all you EE types out there did I just make a cool door stop or what?

Uhhh, have you figured out which part made the smoke? If you can't see it, get your face up to the motherboard and scan the whole thing with your nose. Look for dark spots, blistered parts, black resistors, and other signs of "accelerated decay". If you can't find it, flip the m/b over and do the same.

If you're lucky, it's just the burnt part that's busted, and you can replace it and go on your way. But few hackers are so lucky... if the part fried to a short, it might have taken some neighbors with it.

I'd check the power supply first, since you were tapping a power source.

Also, you mentioned you were sharing power with a fan outlet. The fan outlet is soft-switched, so you might have fried the switching power transistor. It wasn't meant to power something as heavy as a drive -- just a fan.

Good luck!

Ya, it smoked from the 12v lead. And I was not sharing the lead from the fan, I was using the second 12v lead that was on the board

There is no second 12V lead. It's MINUS 12V !

I just tried this with mine, it works without a load. Disconnect your power supply from mobo end, make sure wire does not touch anything. Turn power switch on, measure 5V (red) +12V (yel) black is ground, blue is MINUS 12V (-12V). If you get nothing, switch power switch again, you can't tell if it is on or off. Do not short across pins!

Done? PULL THE PLUG!

I didn't have a monitor handy so I can't say if it will boot without the -12V, but I think you may have blown that. You could hook up a normal power supply from a PC to do a test to see if you blew your Surfer. You would need to change the wiring on the connector to match the surfer!

Don't give up yet!

New MessageRE:Damn Mine is dead UPDATE I FIXED IT (modified 0 times) FoOl
Hey all,

I fixed it, I found that the 12v lead on the mobo that the fan was installed in stock was only pushing 8v for some reason. I Still don't know how this happened. So I got some of those neato 3M splicer blocks and added the harddrive power inline, and moved the fan power to second 12v lead ont he mobo (close to the power supply) and all worked fine. I have no idea what I did, since the fan is now running on the same lead that smoked out, but the other one is off volts....
