I found a bunch of ultraviolet LEDs at a surplus place and
bought them for a buck a piece; they seemed like a good buy at
the time. But I realized later that I really didn't have a
good practical purpose for them.
Does anyone have a suggestion for using UV LEDs?
Thanks
Make floater lights for your bike, rollerblades, kid's tricycle, the dog or
cat, and your mailbox.
Walk around house with an LED, resistor, and battery held together by your
fingers and Scotch tape, pointing it at various things and saying "Hmm, not
fluorescent" until someone else goes crazy.
Try to make a UV circuit-board lightbox until you realize that not only is
the wavelength too low, but milliwatts of power don't mean a very fast
exposure.
Try different highlighter markers until you find one that glows, scrawl your
name on a piece of paper and prop it up at work with a UV LED pointing at
it.
Get neon cables for your computer, gash a huge window in the side and light
it up. No reason necessary or possible.
Resell them on eBay with a four-page-long rant extolling their virtues in
large-sized multicolor fonts.
Set up an admission booth to your house and require all entering to have the
invisible UV stamp on their hand.
Use the LEDs to create a line-following robot that follows a UV ink line
invisible in normal light. Whoa...I think that was actually a serious
suggestion. Maybe now I have something to do with my OWN stock of UV LEDs
bought on impulse?
