12 LED Accent Light
This is a wonderful little 12 LED
Accent Light project to use wherever you like.
cupboards to light up your counter top space or on your desk to
light up your work space and save on electricity at the same time.
I noticed that Amazon has ideal
perf boards on
their website. You could load 12 LED's onto one, hard wire the
circuit and place it in some kind of enclosure. Just click on the ad

Here is the
schematic, just click on image to enlarge...
All Resistors are 1/2 Watt. Any
standard LEDs will do. I recommend using the Super Bright White LEDs
in the parts list below for more light. This circuit is drawn using
an AC to DC Power Supply incorporating a transformer and bridge
As an alternative, since most wall transformers,
(Wall-warts) are 120VAC to 12VDC, you can eliminate everything to
the left of the LEDs and just wire it straight across
with the plus side going to the resistors and the minus side going
to the cathode of the diodes, (ie: ground).
