In for one (again!)

I really love it. I heard a lot of concerns about the electrical safety and checked mine thoroughly, but it was fine. It heats up a bit slow and is quite loud, but I usually do not have it on all the time, so this does not bother me. It is quite powerful and heats up even thick ground plates quite ...

...or maybe the 32MHz clock could just be running at 3.3v in the first place, by transplanting the crystal?

Run it through a spare lane on your level shifters.

A little overkill, but maybe this guy...

I think you could coerce some of the IDT fanouts to work as well.

... Though I guess the IDT stuff may be easier to solder as they (IIRC) are larger packages.

Yup, I solder them by hand fairly easily.

Looks nice! Do need some heat shrink on the terminals inside tho. Yeah, shrink would definitely be better. I should've made the box a little bit longer for that to be practical. What you can't see is that I put some glue blobs on both sides of the pcb to keep it in place. So I'm not worried that it...

OK, what chip did you use ?

Have you guys looked at the IDT QuickSwitch devices?

"Probably won't work edition" has landed in Ohio. =D

Probably the normal way is to just use a regulated 12V power supply, and use a internal 5V regulator.. I don't know much about external drives, but you may not even need 12V.. Only the really old drives generally need that voltage... I've always run my external drives just from a normal 5V brick PS...
