Hi Nooby,
A little bit of homework for you:
EDIT: I fixed its spelling and grammar errors.

10 ohms is brown, black, black. The 3rd color of black shows that you don't add zeros after the 10. :lol:
EDIT: Corrected.
 
i would need :
10 ohms=black/brown/black
1k=1,000 ohms=brown/black/black/black
22k=22,000 ohms=?????
220 ohms=red/red/brown/brown/black????
 
Sorry that I got 10 ohms wrong before, I've corrected it.

Almost correct. One LED is supposed to be a diode.
Your 220uF and 470uF caps look like little 220pF and 470pF ones.
