Yes, R9 is not represented, as it is going to be soldered directly on pins 2/13.
Ok, but you should have told me first..
Did you fix the other error OK.?
EDIT:
Looked at your last layout image, looks OK.

Thank you very much Eric!
I've had some troubles with the sensor.
When I power it, the piezo starts bipping non-stop, no matter where the leds are. In fact, even if the two leds are disconnected, it still bips.
- Both LEDs are working fine (I tested them out of the circuit with a DMM)
- D3 shows continuity on both ways - a diode shouldn't do this!
- C1 shows continuity on its leads.
- C5 shows continuity on its leads.
- C6 shows continuity on its leads.
- Not really sure about C4, but I think this one is ok.
Do you have any clues.
The buzzer I'm using is rated at 6v, although the circuit is optimized for 12v. However, I power it with 6v and it works the same way - a constant, irritating beep.
Do you have any clue on what is going on here? Can you help me out?
+Vs - 9,6v
A - 0,48v
B - 0
C - 0
D - 0
E - 0,05v
Though I have to add that these were taken without IC1 nor D1/D2 (IR Led/receiver).
I'll take note of those voltages with IC1+D1/D2 later today.
IC4 (NE555)
1 - 0v
2 - 0,05v
3 - 8,2v
4 - 9,52v
5 - 6,3v
6 - 0,05v
7 - 0,05v
8 - 9,52v
I already tried it at 12v today at school, but with no luck.
It does make a continuous, non-stop bip. Yes, I've tried with both LEDs, close together.
Isn't D3 working badly?- D3 shows continuity on both ways - a diode shouldn't do this!
- C1 shows continuity on its leads.
- C5 shows continuity on its leads.
- C6 shows continuity on its leads.
- Not really sure about C4, but I think this one is ok.
