Been awhile since I have played with a 555, but I seem to remember something about different types.
What are the numbers on you 555s?

I swapped to a different breadboard and its starting to look a little better. The metranome circuit worked. Ive put it back how i had it to start with and it seems to be oscillating but not properly.
The circuit ive been copying is the Infrared Emitter 555 Schematic.
The chips i have are NE555N. Aparently the ones that start with NE are good for driving LEDs etc directly

Mold...Mold on the bread board.
You may be picking up some stray capacitance someplace.

I think its just got a few bad connections on it.
The circuit still isnt working. Ive had a look at the output on my picoscope and its not a 50% duty cycle. I dont really know how to read the results properly but im pretty sure its the wrong frequency too.
Im gonna go sleep on it. My head hurt a little after reading that link you posted. I think ill go back to the metranome and mess with some values tomorrow.
