I made a tutorial on how to light up etches but not how to do the actual etching itself. I will have a few tie ins on how to light it up but if you want more info on how to light it up check out my other tutorial.
Step 1: Design
get a design I used the thundercats logo. then blew it up by drawing it myself!! then taped it to the piece of plexi glass. then I hand etched it using an cordless dremel tool. when etching alway try to go down and left this will get a cleaner and deeper cut. notice in the picture the logo in backwards?! this is because I want the cut into half on the back so when flipped around the logo is the right way.
Step 2: Cleaning up
now that the etching is done time to make the plexi glass look as good as possible to do this you will need WARM not hot water, rubbing alcohol, windex, dish soap, and simple green (not needed but this stuff is awesome!!) make sure that the protective plastic coat is taken off. as mentioned before make sure the water is warm not hot, if the water is to hot you will end up warping the plexi glass. now mix all those thinks in a big bowl the quantities aren't that important. now soak the plexi glass in you concoction of cleaners. get a rag and star rubbing both sides of the plexi glass after you think you have the plexi clean do a gentle rinse down with first warm then cold water.after that take some paper towels and lay them down then on top of that more paper towels and dry it off.
Step 3: Tie in with other tutorial
read up on the other tutorial to gain a better understanding of how -to all I did was slide the plexi in the pvc and glued it then put the light in and glued it on both sides then glued the circuit board on top.
