    You can get a step-up voltage converter to convert the USA 120V to UK 220V. But you may find it's easier and/or...

    Try a Google image search for NiMH discharge curves to get an idea of what you're looking at: <a href="https://images.google.com/images?hl=en&rlz=1B3GGGL_en___...

    I agree you will need a heat sink. A 12V to 3V linear regulator system will likely get hot at any appreciable...

    Newer PICs may be better. Old ones used to drop a lot of voltage when sourcing current.

    Good posts. In my experience, PICs do better sinking current than sourcing. I would recommend connecting the LEDs so that the PIC...

    It will decrease. No battery provides a perfectly consistent voltage over time. As a general rule, rechargeable types will provide a 'flatter'...
