The projects keep on coming. This time is a little lighting project that I wanted to accomplish as cheaply as possible. Searching the internet I found I could order LEDs direct from China for 3.75 USD per 100. That's less than 4 cents per LED! These are warm white LEDs.
For 29 cents per 3' piece, I got 3/16" dowels. 560 ohm resistors were 25 cents a piece, and lamp shades were 43 cents a piece. The scrap wire is free. That works out to about 60 cents per working lamp post.
The be even more economical, some of my lampshades are made from plastic wheels (free), taking the cost down to 17 cents per post.
What follows are some night-time shots of my layout using this cheap lighting method. Oh, the 9v wall wart, used for the power source, was from the junk box. So no cost there, either.
Regards,
Jonathan
