    Sorry for the ignorance but I'be been around electronics for some time and never seen a resistor value written like it is in the schematic. So question is what is the actual value of the resistor in Ohm's?

    3R3 means 3ohm3 so the resistor has to be 3.3 Ohm.

    Hope this is helpfull for you?

    I bought all the parts at a local distributor of electronic parts over here in Belgium.

    plus, the IC1 "78xx" means the family of 78xx regulators. For a 5v regulator, you want the 7805.
    yes, that is actually what i meant, oh well, posting at 6am after not sleeping has its disadvantages..

    Yup that's correct.
