One of my first “proper” projects after a myriad of boxes, kerf guides and other bits… An edge-lit LED lamp made from an old Soviet astronomical map - which I forgot to mirror before engraving. Colour change happens with an Arduino, the colour knob adjusts hue, saturation and value.
For future projects: Does anybody have a source of pre-made edge lit light bases?
There’s another thread somewhere with links to bases on Amazon – I’ll have to leave the searching to you, since I’m making myself late for work as is! I think the cheapest ones were around $10.
I get mine off of eBay. I search on LED Menu and there are usually a bunch. They come with a plastic sandwich board where you’re supposed to slip in a menu insert but it’s crap plastic and I throw it out.
They come in a variety of fixed or changeable colors and run from $5-7 or so delivered. They’re battery powered and ship from China so it does take a couple of weeks but I keep some on hand and just reorder when I’m getting low.
The ones I’ve gotten have a slot that’s a bit thicker than 1/8" acrylic but thinner than 1/4" so I use the thicker acrylic with an engrave on the bottom to let it fit snugly.
Great design brought to life! My first couple I did, I also forgot to invert the image as well. Nobody I showed them to noticed that they were supposed to be the other way around
