Lamps Led
I'm designing an LED lamp and need to convert 120v to 12v for my circuit. What is the simplest/safest way?
I know I can use an AC adaptor but I want to create the transformer myself. Most LED designs seem to run off batteries but I want my lamp to plug into the wall/mains. I'm new to wiring but have done basic soldering and could handle a design using basic resistors/capacitators/whatever else I may need.
The simplest adapter uses a linear regulator. Switching adapters are much more complex. The attached reference shows the steps involved in constructing a typical linear power supply. It's a good place to start.

Do touch lamps use more electricity than other lamps?
there was a recent spike in my electricity bill. There is nothing different about my household from the previous month other than a recently purchased touch lamp. This leads me to believe that it may be the cause for the jump in my electricity bill. I know that touch lamps work by sensing the extra current in my body to flip the switch. I wonder if the lamp constantly detecting how much current is running through it uses extra power than a normal lamp. i have no idea, and it sounds kind of dumb, but i was curious if anything had heard something of this effect.
touch lamps do not use that much power the eletric co here just incressed the raye they charge i bet your's did too.
