List of DIY Electronics Engineering Projects


We can blink two incandescent bulbs alternatively in 230v by using starter bulb
called "STARTER".

Connect 2 bulbs serially (serial connection) using proper graded insulated cables,
then connect the starter bulb parellaly to the second bulb (otherwise starter will burst out) and check out the starter must be in middle of two bulbs.
Always use 100watt bulb as second one and 40watt bulb as first. finally connect two terminals
to power supply (230v single phase 50hz).
By covering the bulb with colour paper we can use this to decorate christmas trees.

Please refer circuit diagram for more info.

If it didnt works please interchange the bulbs1&2.
