Special thanks to Klaus who helped me a lot throughout the DIY work. It' had been painful to figure out the bug that I carelessly made by misreading the resistance of 22.1ohms and 33.2ohms as 221ohms and 332ohms respectively. He simply gave me a hand that took me out of serious troubles.

Duck-Twacy,
Thank you very much.
The PCBs are bought from KK in Croatia.

You can place an order whenever you like, as this is not a group buy.

Thank you
I think I've invested more on the caps instead of resistors.
Actually the attenuator is bought from Taiwan. It costs me around $40USD.
This is a good price
Are the resistors 0.1% dales? I paid more than 0.5$ for one!

Out of curiosity, what is the voltage across the blue LED? I've never used one, but I found some in rather, er, minimal packaging at a local electronics shop. Other than stating that it would produce 10 mcd illumination at 20 mA bias, there was zero information about it.
