Nice! However, be aware that a lot of external drive enclosures don't bother to connect the +12v pin, so check that if you want to use a Gotek drive in an external case.

1 x BC547 or similar bipolar transistor
1 x 1k resistor
Interesting - is the storage time of the BC547 not a problem there? (The step signal's nominally high, and goes low very briefly when the head steps.)
