Halloween Project Pt. 1

Well I have been asked by my loving wife to think of a halloween costume and as with every year I find it hard to think of something that I could be and not look like a dork.  So I find out that my Nephew is going to go as Steve from Minecraft.  He also has a small box that was turned into a Creeper.  And he has it as a small box thats is just a creeper head.  So I figured I can do something like this! And decided that I am going to be going as a giant Creeper from Minecraft!

But talking to his dad I said that I was willing to make his small box Creeper’s Eye’s glow for them and so I am going to make my giant Creeper Costume eye’s glow too but this will not just be Green but also red.  I have come up with the Schematic but still have some testing and to buy some parts for it.  So now I will need to go to my local Radio Shack this week and buy a few things to get the list is below.

  1. 555 Timer
  2. 1µF Electrolyte Capacitor 16V
  3. 2x Green LED
  4. 470k Ω Resistor ¼w
  5. 2x 1k Ω ¼w
  6. On/Off Switch
  7. 2n2222 Transistor (Maybe)
  8. PCB Board
  9. 20 Gage Wire
  10. 9V battery Connector Socket

So the Timer is going to be the main part of the application because it will be what will regulate the power over the whole design of the application.  This is a small chip that is setup to send pulses of electricity out some of the pins while lowering the voltage down.  The Resisters also help lower the voltage and the wattage down so one you do not burn out the LED’s you place.  The reason for the capacitor is so we can spike the LED’s and make it look like a slow glow that we are looking for.

The reason why we need the PCB Board because we need to use the traces that will wire up the whole Circuit.  The 20 Gage wire will be used to hook up the eyes from the board to each of the eye sockets of the box and then be able to hold the device in the box out of the way of my head.  Soon as I buy the parts I will submit part 2 of this project and build.
