    Mastero, Great work. My only question is will the Sproggy relay support that much power? The highest I can find is 12A or 16A. Unless you are using a different one than those of previous version.

    Cool Parts list?

    Maestro,

    Could you post a parts list for the 4.5 PSU? I can't speak for others, but I find it very hard to make out all the parts and numbers from the pcb graphic.

    Thanks Maestro

    I don't need the kit, just the partslist. I like building the project myself. Already got the PCB making stuff and all the relevant links I'll need.
    Thank you for the great work.

    I made my own list of parts. I doublechecked it for omissions but I could have missed a part or two. It has all the chips you need to order though.

    P.S. Maestro, could I use vertical Inductors versus the horizontal ones you have in your PCB layout? I was thinking vertical might get a little more airflow.
