If you have ever wondered what’s the best method to see a scorpion at night. John Bokma has the answer! An array of UV LEDs lights them up magically. John has put together a page with full instructions on building your own.
“Some time after reading “A Powerful New Light Source for Ultraviolet Detection of Scorpions in the Field” I decided to build my own scorpion detection device instead of buying an uv flashlight. Since so far I have found 4 scorpions on my roof, I decided that I simplified the design by using an universal adapter with an extension cable instead of batteries for power. I have plans to make a portable uv flashlight later on.”

I’m very glad I don’t live in an area where this is needed. Cool idea though.
Dangerous critters indeed!
