[One
To Three volts, Applies To Amber And Red, Check for Voltage On other colors.]
Variable Rated OHM RESISTORS
Length of 18 or 20 gauge STRANDED WIRE ONLY in Black and Red
Take
a two inch piece of plywood edge cap. Measure and find center on length and
width. Mark. Measure half inch on each side of centre mark. Drill appropriate
size holes in centre and on each side of center and push LED LIGHT through it.
There should be resistance pushing LED LIGHTS through holes. Led Lights have
two wires coming out of them. Long one is POSITIVE, and SHORT ONE NEGATIVE.
Tie all short ones together and all long ones together. If using one to three
volts lights you have nine volts now. You need a standard 1/4 watt 300 OHM
RESISTOR to lower the voltage to nine volts. You SAY put four three volts and
it comes to 12 volts so no need of resistor? OK, TRY IT. DID YOU BURN OUT YOUR
LIGHTS? SORRY ABOUT THAT. Never equal twelve volts. Solder your resistor to
the POSITIVE side of your lights. Also solder all connections.
Your
resistor can be soldered to your positive side of Led by either lead coming
out of it. Try putting a set together just loosely on the work bench to see
how it works before putting them in the case. LIGHT them up. If you burn one
so who cares as you can put other one in. Cut all leads to stay in the case.
Attach 18 to 20 gage wire [Black, Ground, RED, live] and attach to ground and
live side. Solder them. Test before soldering output leads on. Push negative
leads to one side and positive lead to the other side in the plastic case. Use
hot glue to hold everything in place so they do not short out. Test again. If
everything OK, Fill cavity over the leads with HOT GLUE. This will seal
against moisture.
This
will give you a three LIGHT cluster. If you want a six LIGHT Cluster cut a
four inch piece of plastic plywood edge cap and do it the same way. Use two
resisters for each set of three in the four inch cluster. If you want a five
LIGHT cluster, do a three and a separate set of two using a 1/4 watt 430 OHM
RESISTOR for the second gang of two LIGHTs. On the six and five cluster you
can tie the live wires together after the resistors. The ground may all be
tied together.
The
lower the voltage the more LED LIGHTS you can use for the same RESISTOR VALUE.
Try to find TWELVE VOLT LED LIGHTS AND YOU CAN CONNECT AS MANY TOGETHER
WITHOUT USING RESISTORS. They are much more expensive. I pay twelve cents
apiece for LED LIGHTS and three cents apiece for resistors, edge cap molding
cost me one dollar and fifty cents. Approximately cost for LED LIGHTS IS ABOUT
2 or 3 dollars.
