/diy/ - Do It Yourself

My dog ate part of a remote gate opener, this is what i was able to rescue.
I guess the best choice now is to send it to repair or to buy a new one but sadly that is quite expensive in the place where i live.

So here are my questions:
>Are the orange circled things mini resistors?
>Are the blue circled things fuses?
>What is the red circled thing?
>Do you think i could repair it using 'normal' sized resistors and/or other components if i have the original design of the circuit?
