Hi Everyone,
I'm looking for some help designing a circuit, I've got a string of LEDs (Christmas lights) and every other wire is connected in reverse. The supply is DC 32V 0.19A (see below).
So when I connect the power one way round all the even lights come on, when I connect it the other way around all the odd lights come one.
I'm looking to make an oscillator circuit (probably with a 555 timer, 4017 and some transistors) that will flip the positive and negative supply to the LEDs with sufficient speed that they appear on contantly (60Hz?) something like the below, however much faster and instead of an LED on each step all the even steps would go to one transistor and the odd steps to another. These transistors would then deliver the 32V straight to the LEDs.
The following is not strictly accurate but is effectively the situation in terms of the final output:
I'm not certain on how to link up the transistors and what resistors and capacitors etc I need for that supply and speed so any help is much appreciated.
Thanks!
