this project is pretty easy I did it in a total of 2.5 hours (including etching) the list of things needed is
a neon for pc or a car light
about 1.5' of pvc
plexi glass
12v adapter
the tools needed are:
dremel
hot glue gun
radial arm saw
stationary sander
and a computer
Step 1Designs
go on the internet and look up designs relatively easy design such as steal your face, the mortal kombat logo, thundercats logo,and the instructables robot. I stole mine and changed it to black and white using photoshop 15 or adobe. make sure the design is backwards. after that print it out and tap it on one side of the plexi glass make sure you see the picture IT HAS TO BE BACKWARDS!!! after thats set start up your dremel and etch away. if you need tips on etching search it on this website you'll probably find something.
