Powering an IDEFile inside a 2/5

(1/2) > >>

compu_85:
I have 2 of Patrick's excellent IDEFiles, would like to mount one in the empty space of my 2/5.

Question: Does the +12v supply on the Twiggy cable have enough umph to safely power a Conner 3.5 disk? It looks like the running draw is about 7w. 

Thanks!

patrick:
A Twiggy Drive draws up to 1.6 A on the 12 V rail and up to 0.4 A at 5 V. So I assume this will be enough for the Conner Drive.

To be sure you could start with a CF card or DOM module, and if everything works properly switch to the spinning rust with its authentic sound :-)

compu_85:
I soldered on to the Lite adapter for a completely reversible mod.

It's working great!

Thanks,

-J

BTW, on the 2/5 wiring harness there is an unused 3 pin connector with +5V, +12V, and Ground available to use for powering drives as well.

You are right concerning +12 V (white-orange) and Gnd (black).

But (at least on my 2/5 harnesses) white-green goes to pin Y of the power supply connector. For the later PSUs this pin provides a power-fail signal that is used inside the 2/10 to reset the Widget. For ealier PSUs (1.2 A single line voltage model) according to schematic 050-4011-J Pin Y+21 are not connected.
