isekii's Question of the Night~ LOL PATENT PENDING :)

[isekii]

Alright , as you all know, I post questions when I'm curious about certain things.

As you all know there are 2.5 hd converter to the traditional 3.5 eide adapter.

do you know if there are any 3.5eide ---> 2.5 adapter ?

how feasilble is to make it oneself ?

Thank you.

I prefer cheddar

Just buy it..

If I knew where I would

I have some 2.5 ----> 3.5 adapters but not the 3.5---->2.5 adapter.

I can't imagine there being much of a market for such a device for obvious reasons. Good luck.

But there is

if one can make one, you can use the laptop external enclosures that they sell on ebay for like 5 bucks.

Are you trying to squeeze a 3.5" drive into a laptop? :Q If you can pull it off, you'll be my hero. I'll bet it can't be done for a very simple reason, 3.5" drives requires an external power source, 2.5" power is integrated into IDE channel.

so does the laptop hd's when you use the converter.
all it requires is that 4 pin molex ? thingie attached to the pcb.
I just checked out the laptop hd adapter. it had 4 pin slot. but only 2 of them were being used.

No i'm not trying to put a desktop hd into a laptop but putting a desktop hd in a laptop hd external enclosure ( Modded of course )

to make one, find the pin-out of the 2.5" and 3.5" HDs, i bet they're out there somewhere on the net. then match up pins.

would i need to mount it on a pcb of some sort ?

nope, you could use pin-to-pin connectors (looks like a slender plastic pen barrel with a hook coming out of the end) or something, as far as the connections go. or something, just connect em up.

i'm assuming here that the data pins are separate from the power pins on the 2.5" pin-out diagram. that's most probably the case (kinda impossible to send a low data signal and a positive voltage on the same line, and manage the keep them separate...)

i think your problem would most probably be the power connection... maybe make a separate power source and use a ac-dc converter to supply the required voltage?

edit: i'm guessing you need something permanent as far as the pin connectors go... in that case, design a small pcb connection, not very hard at all (doesn't cost much either... several pcb makers often give you the first pcb design free as a sample). it would look something like below...

. <- from 2.5" data pin
| <- trace to conduct the electricity
. <- to 3.5" data pin

lay out the wires sideways and do that over and over again, and you have yourself a permanent solution

I think I kinda understand what you're saying, who can I contact about the PCB ?

I think I kinda understand what you're saying, who can I contact about the PCB ?

the projects we do at school, we use express PCB (http://www.expresspcb.com/ExpressPCBHtm/Costs.htm)
we use the mini-board service, which works out to $62 after shipping for 3 boards. kinda pricey... they have their software you have to use when submitting a layout to be etched.

if you have a frys or another electronics store nearby, buy a pcb board with holes punched in (cheap) and a solder pen (cheap), and do it yourself! since you're basically gonna be playing connect the dots, i don't think you'll have a problem doing it yourself. solder wires going from the 2.5" HD pins onto the board. solder wires going to the 3.5" pins one hole over. then use the solder pen to draw a line connecting the two holes. pretty easy. when you're done, just use a hacksaw or something to cut the baord to whatever size you need.

to connect wires to the HDs, they also have these little wires with a female connector on one end (forgot what they're called =/). just roam around an electronics store enough, and i'm sure you'll find them. the connectors snugly fit onto one pin and stay on unless yanked off.


OR


just buy an ATA cable and cut it in half connect appropriate wires on both side. if you don't mind something not very professional looking, buy an ATA cable to the 2.5" and 3.5" devices. cut into half, connect individual wires together and tape the connection (to prevent wires from touching each other) -> basically splice the two wired together. then tape it all together into one big-ass bundle the hard part is figuring out which wire goes to which pin, but just open up the end connectors and see which pin connects where... takes some time, but you'll figure it out.

you'll still have to figure out a way to power the HD though, like i said...
