    They have a C44K in the component or something like that its not at all visible.

    You need to adjust the lighting and, with a magnifier, read all the markings on each part in order to identify what you have. Even then, sometimes that won't help.

    Actually, you need to use indirect lighting. A flash is almost exactly what you don't want to use.

    Take a photo outside in the shade of a tree on a sunny day (or with similar lighting)

    I can actually read most of them though

    The 811B may be a DS1811-10 (5V +/-10% reset)

    The K44 could be a 2SK 20-44 (fet) or a BAS40-04 (schottky diode).

    That's all I can find, sorry.
