Side project.

Today I'm just working on the side that project which is science project. Here the pictures :

Quiet boring but interesting.

Thinking. Why it's burn.

I'm wondering why my transmitter burn. I have been thinking a few days but did not get the answer. I think it is not about the overload cause I just give 5V. My supervisor also ask me the same question, how much power that I apply then I said just 5V not more not less. Then why it happened?

The part that burn.

And, I still working on it.
