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.


The following picture shows the main pcb

The Blue Led act as constant voltage source as part of the power regulator...

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.
