Requirements:
- 10 Super Deep Red 5mm LEDs NTE30041 (2.5V 25mA)
- 10 Super Orange 5mm LEDs NTE30040 (or Amber NTE30042) (2.5V 25mA)

- 1 or 2 sheets of 1mm styrene plastic ( or you can use 4mm styrene if you can find it)
- Cyanoacrylate glue (i.e. super glue or any other kind of good modeling glue)
- Testors Clear Parts Cement/Window Glue (optional)
- Bond Glazing & Spot Putty 4.5 Oz (optional)
- Lots of 24 to 20 gauge sold wire (NOT stranded)
- Wire cutters and strippers and needle nose pliers
- Black heat shrink and a heat gun or, in a pinch, a lighter
- Solder and solder iron
- Various grades of sandpaper
- 5mm drill bit and a drill to use it in
- 1mm drill bit or smaller
- Xacto knife, scissors and a straight edge
- A set of four small clamps
- Small piece of stiff board or cardboard and a pen or pencil
- Dremel tool with a drum sanding bit (optional)
Purchase:
You can use any kind of LEDs that you want. Just make sure they are Super Brights and that you get the specifications. If you use something other than what I listed above, make sure to recalculate your resistor values using the specifications provided with the LEDs. MetkuMods has a great page for calculating the necessary resistance. Order the electronics through an online shop or if you have a good electronics store nearby you can hit them up for the parts. And get the wire and relays through them as well. Make sure the relays are 12VDC and can switch at least an amp.
For the styrene and glue, visit your local hobby shop. If they sell train sets with the fake trees, buildings and people then they should have sheets of white styrene. Look around for bottles of CA glue. I would avoid the fast setting glue as it can be a pain to work with. I recommend the Testors clear parts cement as a sealer to prevent water and dirt getting into the enclosure around the LEDs or the wire hole. |
