New Hardware project from the father of the Passkey, heres an excerpt:
I was busy the past couple of month, so this is the first post after a long while.
To get back to hardware development, I decided to do a quick IDE to GBAMP hack. I also took a few pictures for the few people interested in doing this (at their own risk)
You might not know it, but CompactFlash memory cards use IDE interface; and hence it’s possible to map each IDE pin to a corresponding CF pin. Unfortunately, DS delivers only 3.3V to GBA slot and so an external 5V power supply is required. I used a 11.1V li-poly battery and a DC-DC converter to bring the voltage down to 5V.
