GRINCH Controller Assembly Instructions

==Board Assembly==

Assembling the GRINCH should be fairly easy for most hobbyists. The following sequence of steps is by no means the only way to do this. It is simply a suggested order of events to achieve the desired goal.

 
*Start by checking the PCB over for any production faults. Ensure that none of the tracks are shorted or open and that all holes are clear.

*Install the four 0.1uF capacitors (PN# 581-SA105E104Z). These capacitors have no polarity to worry about.

*Install the power LED (PN# 604-WP7104GC). The LED must be oriented correctly, if your LED has a flat side then match that to the overlay on the PCB. If not, then the shorter lead of the LED is the cathode and will go in the square solder pad.

*Install the power LED resistor (PN# 660-CF1/4C471J). Make sure that the resistor has a value of 470ohms (yellow/violet/brown/gold stripes). The resistor has no polarity to worry about.

*Install the power connector at J2 (PN# 538-70543-0001). The square pad signifies the +5 VDC connection.

*Install the 2 pin vertical header at J1 (PN# 538-22-03-2021).

*Install the four 24 pin IC sockets (PN# 571-3902618). The sockets must be all aligned in the same direction with pin 1 of each socket aligned with the square solder pad. Another way to verify that you installed them correctly is that the notch on the top of each socket will be toward the RJ45 IN/OUT connections.

*Install the 18 RJ45 jack sockets (PN# 571-5520251-4). Due to minor variations in manufacturing, some RJ45 sockets are a tighter fit than others. Care should be taken to ensure that the pins are aligned first before applying too much pressure to seat the locking lugs through the board.

*Install the ICs into the IC sockets. Ensure that pin 1 of the IC is aligned with pin 1 of the socket. Can be verified by noting that the notch on the IC is aligned with the notch on the socket.

Led Lighting

2010-01-09T18:02:21Z

Eroberts:

==Overview==
There are many ways everyone is looking to go green, and Christmas displays are a innovative way of doing just that. The possibilities are endless with all the
new offerings from companies on led light strings and led retrofitting to even custom built led lighting.
 
Led lighting has many advantages such as:
<UL>
<LI>Energy Efficiency
<LI>Long Life
<LI>No color fading
<LI>Bulbs are cool to the touch
<LI>Immune to shock or vibration
</UL>
 

===What does Half Wave or Full Wave Mean===
Because light emitting diodes are essentially a diode they only conduct one way and alternating current changes phase 60 Cycles per second in the United States and 50 Cycles per second in Europe and other parts of the World.
 
Store bought Led Lighting that states that's its half-wave is that the Leds only conduct(Light) on one half oc an AC Cycle> With a keen eye you might even be
able to spot this as a flicker especially if you move your eyes across the led bulbs
 
Full-Wave first uses a bridge rectifier to make dc before it goes to the Leds themselves, This creates a DC pulse of 120Hz or 100Hz depending where you are located at. this higher frequency usually is not as noticeable to the human eyes.
 
Because Leds are solid state devices they can react much faster to changes in voltage. This has always been going on with incandescent lighting but the filament cannot react to the fast changes or cycles so that is why we always see it as a steady burning light bulb.

==Led Lighting Options==
[[MR16 LED|MR-16 Led Flood Lighting]] Low Voltage Led lighting to throw color onto displays or other objects such as a wall of a house. 
[[Led Strip Flood]] Custom RGB LED wall wash (designed by Frank Kostyun) 
[[Portaflood|500w Portable Floodlight]] Low Voltage Led Modification to allow Red / Green / Blue or a mix of any color to create 16 million color probabilities. (designed by Matt Edward withpcb help from John Wilson)
