    Hi!
    Could enyone please tell me which photo diode i have to use ( bpw 43, bpw 34
    or sfh 203?) for detecting beam from laser pointer. ( I don't know the
    wavelength but it's simple laser I bought in market - about 4$ ).

    thanks

    Not entirely sure of the wavelength that's being
    emitted by your pointer's light source, but I'd
    venture it's 640nm. Either way, any detector cap-
    able of detecting visible light (in this case
    "red") should work...
