    Default How to etch a driver board?

    I saw that Bengal had a driver board that looked home-made. Just wondering how this was done.

    Hi CTR...

    Welcome aboard

    I believe it was this circuit he used .. Courtesy of Sam's LaserFAQ

    If he ever comes back and visits us , He can tell you for sure how he etched it..

    I imagine he used double-clad PC board material and drew the circuit traces on with a black "Sharpie"
    then used etchant solution (Ferric Cloride) to develope the board (eat away the unused copper).
    Hope that helps...
