Strange Small Electronics Project: Can You Help?

Hi Friends,

For a prop, I'm looking to build a small plastic box with a belt clip. Box will have 9v powered LEDs in bezels on the front face and an external on/off switch.

Adding some sound (beeps or buzzes) would be great but is not essential.

I used to build stuff like this back in electronics class, but I have no idea where to start now.

Happy to purchase a pre-made solution if something close exists.

Thanks for your suggestions.

SR

you can make your own from scratch with a small battery, resistors, LEDs and Switch. You probably can use a smaller battery, like 2xCR2032 if you want to keep this small and light.

Look for dog collar lights, you may be able to use one of those, you may not need to make any modifications at all.

agree smiley

9v may be overkill for LEDs, not to mention the weight.

Try Jameco Electronics

steve,

Bicycle taillights and headlamps are readily available. Many have built-in clips. Most of them have several "modes". - fast flash, slow flash, steady, etc. Cover them with perforated cardboard if desired.

Also consider headlamps (for your head). They don't offer colors but water-based paints and/or fingernail paint solves that problem.



Remember how when you were little
you could just rip off your diaper and
just run around naked and everyone
thought it was so cute and funny?


Anyway, I need bail money.

now that I think about it, our local police department hands over these blinking lights to kids on July 4th before the fireworks. I probably have a dozen or so around the house.
