6 pin mini-din power adapter (for external harddisks)

hi so i planned on buying a new HDD dock since i fried my old one while taking messurement with my multimeter (THANK GOD i had the hard drive unplugged)
but the cheap one i want i have read a lot about the power supply failing after 3 day or being defective at ariveal so i mixed this together.

happy building

READ THIS TOO!!!
this will not be the best powersupply but it will do the job

DISCLAIMER. (yes i have to say this)!!!!!!

Step 1: Getting the parts

you will need

*some sort of wall-plug (230V AC in EU or 120V AC in US) to 12V AC or DC power supply.
you can get one out of the kind of lamp in the picture
*a USB cable that you dont min cutting

*a 6 pin mini-din power plug

[all og the following items will only be needed if you use an 12V AC transformer like the ones in the lamps]
*some diodes rated for 3 amps at 20 volts.
*a big capacitor to even out the very unstable DC

Not all disk drives with a mini-din power connector have the same pinout. A spent a lot of time (and eventually a call/email) to Customer Support trying to power a WD disk drive with a LaCie power supply, or vis versa :-( (Fortunatey, the disk survived the experience.)

I'd be more inclined to attach to the internal power supply of my computer, where I have some faith that the 12V wire actually has 12V on it, though the fusing issues (lack thereof) might be a worry...

i agree.

this is a VERY raw version of a power supply. got it working though.

(had to throw a few diodes on to take some voltage on the 12v supply)
