I wana build the this emergency light with a few modifications as i'm new to electronics I need help in the modifications
here's what I want:
I need to build the emergency light as small as possible so can't use the transformer,can somebody provide me with a transformer-less solution to convert 220v ac to 9v dc 500ma ?
the battery specified is a 6v 4.5Ah battery,as the build needs to be small so can't use an sla battery because of its size are there alternatives in a small size i.e in lithium-ion ?
