How to put together an eerily glowing neo-retropostmodern ultraviolet indicator lamp.
This shows the construction of the first two that I made as a way to evaluate the PCB etching process outlined in another Instructable. My idea is to use these as indicator lamps in some other projects.
My son insisted that I enter it into the LED contest because he wants a TV-B-Gone kit, so be sure to vote it up if you like it. (Click the + icon at the top of this page)
You should open this pre-requisite Instructable in a new tab or window: https://www.instructables.com/id/Stop-using-Ferric-Chloride-etchant!--A-better-etc/
It is the method used to do the etching in this instructable and has the added bonus of giving the PCB's a nice green tint.
Eventually I will make stained wood and brushed aluminum enclosures for these. I also plan to make use of these as indicators on some projects. (They are actually quite significantly brighter than they appear in the pictures)
