Highly unlike to have any relay buzz then. Just keep your 150n until you test.

Sorry, I just fixed it.
Should I use the 100uf near the bc517 (I do have a few spares). |

The 100 microfarad between the 2 BC transistors and the 47K resistor is absolutely essential for the time delay to work. Quality=irrelevant.

Nice progress, nothing untoward. The 100uF in the delay bay is missing. Is your solder ROHS?

I sure hope so, I forget where I bought it. Maybe partsconnexion.
I know the 100uf is missing there. I thought the 150nf was supposed to go beside the dc517. I'll put the 100uf in there then. |
