AA batteries. Or you could take a bigger battery (as discussed earlier) that outputs 6V.
About focusing, I think it is critical enough to focus right. Haven't done a real job with it yet, however, but this is from my tests. |

Yes, it is. I have done so with many projects now and it is tack-sharp. I love it.

A bit of DIY electronics work could do a simple job here. Convert 12v to 5v/6v using a few parts on a small pcb, and velcro it to the 12v battery. No need to use separate supplies. Carlos |

I'd be interested in building this if someone could just point me to a schematic or a page on voltage reducers. I can't seem to find any.

http://www.rc-cam.com/dc-dc.htm Something like the LM7805 voltage regulator should work fine. As you can see it's only three parts: one regulator (for the voltage you want) and two capacitors. The regulator may need a heatsink, if the current needed is large. And a small pcb, if you want to, to make things tidier. So it's 5 parts. You will need a solder pen, some solder wire and some cable. You should watch polarities very carefully and check everything with a DMM after it's ready. Never plug your electronics until you are sure polarities are OK. There are other projects like above on the web, if you look around. Some explain things very well, so you can follow the photos. Good luck. |

I'm really interested in finding out how this solution is working out for you. Also which mayflash (there seem to be a lot of them on the website)

I bought the mayflash in this place:
