A Quick and Easy Edge Lit Sign




About: I build therefore I am.

This was made from two bits of Perspex that I used my CNC to engrave Open and Closed into then used a string of LED's to edge light them. A short length of 25x15 trunking and hot glue holds it all in place.

A simple three position switch selects Open, Closed and off.

I did say it was simple :-)

    Hi there,

    I built a CNC a few years back that basically has a Dremel attached to it. The bit I used was a sort of cone shaped coarse grinding bit and at high speed on the Dremel but low speed on the CNC it does not melt the plastic.
    I also ran the program twice at two cutting depths hence the slight offset on some of the letters.

    I have done one free hand but it takes a lot longer to do and if you sneeze half way through.....
