  1. Your sequencing is pretty good for the first year and you did a lot with only 16 channels. One thing that I found out over the years is that people don't like to set through long songs. Get and learn the program AUDACITY and edit your song down to 2 minutes or less. This will keep their attention longer with them watching more of your great show. Earle

  3. And turn your living room into your prop building studio... lights, wires, and props all over the place. All year round.... Did I mention... all year round?
  4. Wait until you get real lights up and the first time you play the show. You will be HOOKED!
  5. Dragging a chase through a lot of visible channels over a several minute sequence is very quick in S4. Seems very sluggish and time consuming in S5.
  6. I’m with Tom. Only gfci popping issues from using vampires and spt are when the connection is setting in a puddle, not once from snow. Worst part about vampires is that with some brands the plastic pieces are cut a hair too tight. So during take down I need a flathead screwdriver to separate the male and females. BE SURE POWER IS OFF!
  7. Here is just another thought as where I work we store wood trim in them and they are very durable. you can get them in many lengths and diameters. The product is Sono tube (that is what it called here in Ontario) it is the form for pouring round cement posts. For end caps we just cut a round piece of plywood and screw it inside at the end. It is available here in Ontario at any Big box hardware store.
  8. I use this to repair and modify my LED strings. Not sure if it will help but will post it for the FYI factor. This is part of a pdf that I found years back on modifying LED strings but the forum here won't let me post the pdf. LED Calculations 1. Peek Voltage - Peek voltage out of the full wave rectifier from 120VAC RMS equals 170V minus the voltage dropped by the diodes. This would result in about 167V. a. Rounded voltages, 120VAC *1.414 = 170V. b. 170V - 2.8V = 167V 2. LED Voltage and Current a. Voltage varies by manufacturer and color for LEDs. The most common current is near 20mA. You must look up the specifications for your LED string. b. In my examples below, I’ll be using: Red = 2.0V, 17mA or 0.017A 3. Resistor Calculation (Example using a shortened string of 26 Red LEDs.) a. Calculate voltage drop of LEDs i. 2.0V x 26 = 52V b. Calculate peak voltage minus voltage dropped by the LEDs i. 167V – 52V = 115V c. Calculate Resistor(s) needed to drop remaining voltage i. Ohms - 115V / 0.017A = 6.764KOhm (Use next higher standard value, for example, 8.2KOhm) ii. Watts - 115V * 0.017A = 1.955Watt (Use a minimum of 2 watt resistor) 4. Rectification – You will need 4 diodes per string to make the full wave rectifiers. a. I use 600V/1A diodes. Mouser part number 821-1N4005 5. Here is a link to a handy online calculator which I use: http://www.horrorseek.com/home/halloween/wolfstone/Lighting/litlec_LEDCalc.html Limitations: This example does not utilize any voltage doubling circuits. You are limited to using the number of LEDs that add up to or just below 167V. For example, I could build a string using a maximum of 83 Red LEDs which drop 2.0V each. This would utilize 166V of the available 167V. Other LED colors drop higher voltages. For long strings, you must divide the string in half and build full wave rectifiers for each section. Tip: When purchasing resistors, you can use one or more. Rather than just using the one 8.2KOhm resistor, you could use two resistors, one on each end that adds up to at least 6.8KOhms or just over that value. I’d also recommend purchasing resistors in bulk where you can. I calculated the resistor sizes needed for each of my strings based on the number of LEDs and voltage differences based on color. I then purchased resistors with a value common to all of my strings but within the closest range of my requirements. This allows me to use the same resistors for most strings, and I commonly only use two different resistor sizes. For example, I have purchased both 3.6KOhm/2watt and 2.7KOhm/2watt resistors for all of my strings. I may use one, two, or a combination of these values depending on my needs.
