What..!! No face shield...No googles..!! Geez I'll have to turn you into OSHA. /DesktopModules/NTForums/themes/mls/emoticons/shocked.gifOh, that's right. You're Canadian. Your workers can get away with that..../DesktopModules/NTForums/themes/mls/emoticons/tongue2.gif
That's a neat effect. How about a little explanation as to how it's done.
The guy on the box has goggles. The 'supervisor' does not. Is that a surprise? /DesktopModules/NTForums/themes/mls/emoticons/wow.gif
Get an old AM radio. Remember amplitude modulation? Too young eh? Anyway, turn it to a station with good volume and cut the wires going to the speaker. Attach the leads to a common 2mm LED (blue in this case but I have used white) and it will light at an random audio rate. This particular;ar one seemed to be polarity sensitive so I just turned it around the other way.
Once I had it working (I ran it for a few hours too see that the 'station' didn't fade away) I set the volume and tone for the best flash and put it under the layout with a new, longer pair running through a hole in the 'ground' under some pipes the guy is welding.
Piece of cake. Give it a try. IF you can find an AM radio. I picked this up as a junk shop for $2.00.
