Wire Model Railroad Buildings with LED lighting

Wire Model Railroad Buildings with LED lighting

Part 1
Planning with pencil and paper

Step 1  State your Objective (your intent)

"My Intent is to have a cool lighting effect inside my building with LED lighting."

Step 2  List Specific Requirements

"LED Lighting"

Step 3  List the elements that are implied by the requirements

"a bridge rectifier and 1k resistor are necessary to LED lighting"
"an additional feature is that this method can use either AC or DC power"
"flexible wire of a gauge 26-30 AWG would be best for this porject"
"hot glue would be best for securing wires in place"

Step 4  Draw a simple diagram to show the plan

"a simple drawing on graph paper, not to any scale, but showing the approximate locations and directions of the elements"

Step 5  Gather the materials to include tools and support tools (tape, glue, rags)

Step 6  Prepare materials (such as tinning the wires and components)

Step 7  Do the construction


  1. What style of bridge rectifier do you use ?

  2. The bridge rectifier is a single phase 400VDC 1.5A glass passivated RadioShack part 2760268

    Here's a link:

    It was in stock as of March 22, 2018. It's $1.50 from RadioSchack, but $4.50 on ebay.

    Beware the prices, $1.50 is pretty good. The only cheaper are usually bags of 100.
