hello everyone,
U must have checked these chinese made decoration lights they have abt 50 LED's connected in series and a small controller with a volume adjust button. Wat i want to ask is tht how does the electronics within the controller manage to run on 230V AC,50Hz. Out of curiosity i opened one and found no transformer no rectifier just one Chip controlling pattern of LED's glowing and also theres coming from the speaker.
The size of the controller is abt say 7cmX5cm. Magic of electronics it seems to me
Post in if u hav any idea abt it.
thnx
Dilu
