    Potentiometers...Where?

    Im in the process of building this

    http://www.gideontech.com/guides/lcd/

    and Im looking for some potentiometers.

    Anyone know a good place to buy some nice ones I can put knobs on?
    I want to put some knobs on my dash to adjust the brightness/contrast as needed but am having trouble locating 2 that are similar. I dont want big ones, small ones will do as long as there is enough room for the posts to go through plastic for mounting.
    Ive went to my local Radio Shack, but they didnt have the sizes I need unfortunatley.
    Ive tried all electronics, but they only have large ones in the sizes I need. Any help would be appreciated.

    for the LCD, 2W should be suffisent. The wattage of the amp is mainly how many power it can support. If you get it too low, it will overheat, just like resistors.

    if you can get 3W or more, its not bad, just more expansive.
