The downside

I am feeling very down today. At the final stage, the circuit developed problems. It was working so well during the prototype stage. And now, I don't know what to do.

I can go to the guys at Pasar Road because they have an Engineer on Saturdays. But for the rest of the week, I am wasting time. The problem started when I was burning-in the circuit for a few more days before I discovered the problem. Seemed like one set of LEDs are very dim and they flash as well as the other set for LEDs. It should not be happening. The problems started once I add in the RED and GREEN leds. The two sets of LEDs robbed the power so much that the White LEDs looked as if they were about to die off. And worse of all, when the other LEDs flash, they followed too. This is a disaster.

And it worked fine during prototype stage.....

With so many boards, it would be a waste. I am in
panic mode now and my savings are gone. Haih.
