Hi everyone been following this thread quite a lot, so I decided to get one of these devices and of course modify it. I decided to run the clock from a Tektronix function generator, all works as expected at 12 MHz. Although I have not modified the power supply yet I notice at any rate about 12 MHz the green led starts staying on longer than the short blip. If I go to 13 MHz it stays on a little longer and at 14 longer still. While it is hashing it seem to be faster but the delay after it gets done acts like it limits it back to the stock freq. I don't know this for sure yet. I also attempted to remove the regulator IC and feed power directly form the lab supply, while the voltage was correct I could not get it to work at all, green LED went off but cgminer said no devices found, put the IC back in and went back to work, I just pulled the chip and fed where the inductor was. It did draw 1.4A at 1.05V not sure why it didn't work unless there is some kind of power sequence thing. I hope to play with it more tomorrow so we'll see if I make any head way.
