Science Buddies: "Ask an Expert"

I followed the diagram to build the vibrational frequency detector circuit that was in your "Measuring Vibrational Frequency with Light project."
I used the second schematic diagram in it.

However, the circuit i built does not function properly.
This link has a picture of the circuit i made using the diagram https://mail.google.com/mail/u/0/?ui=2& ... sp=safe&zw

Could you send me an actual picture of how the vibrational frequency detector circuit is supposed to look like when its on a solderless breadboard.
If you do have a picture of the complete circuit send it to my email which is [MODERATOR REMOVED].
If you cant send me a picture, then send me something that can tell me how to make the circuit properly on a breadboard.
