USB Infrared Toy / Re: What the hell happened?

April 08, 2010, 10:26:44 pm

My IR toy also has the same problem as s3c .What is the point of ordering a "professionally assembled" board if it is defective anyway and needs to be fixed by hand.The components are bent out of position and are crooked - Soldered that way not bent during shipping.Looks like someone was in a hurry and also hand soldered the components

I forgot to add current and voltage annotations
Clock voltage is green
Diode current is blue

After simulation with LTSpice i found that the circuit sinks about 600ma assuming a 5v source and 4.7v zener in the inverse clock cycle.

Im not very clued up with the analog side of digital circuits but it can be any of the following.

Stability / Filter issue with eeprom clock due to power circuit sinking current in opposite cycle -Excess current resulting in timing lag
Some kind of security check/feature on host side to see if someone is "leeching" on line
