I bought the gas detector sensor kit that Dan Checkoway indicated in this
forum

Quote:

http://www.electronic-kits-and-projects.com/4055.htm


It came with a green LED to indicate the presence of gas, but since I want
it to indicate CO in my airplane's cabin, it seems more logical to put a red
LED instead.
I will replace the LED, but my (electronic ignorant guy) question is: how
can I put a blinking red LED? Is it the type of LED or anything else I
should add to make the LED blink?

The kit also has a relay-operated contact which I plan to use as an audio
alarm. Which device shall I install to have that feature? A beeper? Anything
else? Where can I get it?

TIA
Carlos

Carlos, if you send me your postal address I can send you a
blinking red LED. I bought some from Fry's last time I
was in the US, but I'm not going to use them. They take
12v input - I hope that's what you need.
