LED Acrylic Glass Sign





Introduction: LED Acrylic Glass Sign

In this Instructable, I made a LED acrylic sign.

You will need:

For the Sign:

  • Acrylic glass

I used a 100 X 80 X 5 mm sheet

  • Mini drill with diamond burr bits.
  • Stencil knife
  • Picture/print out for the stencil

For the base:

Instamorph moldable plastic

2 LED's with a battery holder, batteries and a switch

Step 1: For the Base

I melted the Instamorph and coloured it blue.

I used "no-brand" pigment.

Step 2: For the Base

I used a wooden box as a mould.

Instamorph should not be too hot or else it will stick to the box.

When I removed it from the mould, I reheated the bottom to cut it off.

Step 3: For the Base

To make sure batteries hold in place, I added more Instamorph.

Step 4: For the Base

More Instamorph was added on top to hold acrylic glass.

Step 5: For the Base

I drilled holes for LED's and the switch.

I soldered LED's and a switch to the battery holder.

Then I glued the switch to the case and inserted LED's.

Step 6: For the Base

I covered bottom of LED's with electrical tape and inserted the batteries.

Step 7: The LED Sign

I cut out the stencil and secured it to acrylic with the scotch tape.

Step 8: The LED Sign

Then I used diamond burr bits to colour the stencil.

Now you can put your art on top of the base and watch it shine.

If you get bored, change it.

Great ible. I love your base.....I purchased this moldable plastic a couple weeks ago and haven't made anything yet but might have to after seeing this one. Nice job hand scribing the logo. That turned out great. I just did a simular project and used a dremel. Thanks for sharing.



Wery nice project. Thnx for share.

NOT A PRO TIP: you can get multicoler lights with a controler from amazon and if I make one of these I'm gonna use that

A great looking project, especially in the dark.

Some tips for those who may want to build:

A defunct monitor may provide a useful hunk of acrylic as well as Mylar for the stencil, which is used as a diffuser.

Flame polishing the acrylic edges will give a nice finish to raw saw-cut edges after sanding or scraping, as well as transmitting the light in a more even fashion. Make the surfaces as smooth as possible and practice on scrap first, there is a small learning curve but once mastered, it will be with you forever. I use a simple propane torch for my work.

Thanks for the tip.

It's very interesting.

I might give it a try.
