I am working on trying to make a set of LEDs flash. Here is what I would like to end up with:

I have a 9V DC powered set of 8 LEDs, which would be normally on, with an On/Off switch.

When the lights are tuned on, and a secondary switch is tripped, the lights will flash for X number of seconds, possibly adjustable duration, but not required,  then go back to solid On.

I have seen some of those 555 chips that seem like they might do what I need them to, I just am not electrically savvy enough to work this out myself.

Anybody got an idea on how I can accomplish this?

Thanks

Hey Dan, might be best to show this past a few other people to check... I'ts late here and I've been building valve stuff for too long, the solid state stuff is a bit rusty! 

Hey Dan,

I had a look over this with a coffee this morning, you will want to use this one, with the other one I did the momentary switch wouldn't work like you need it to.

The new circuit will allow you to push the button once to get the lights flashing for up to about 15secs, adjustable down to a couple of seconds via the pot.

Go with this one. 

Thanks!! I will see what I can do with it.

I didnt read the comments but you could run a simple flasher and bypass it with another switch

so they are always on

 

 

or do this for a flashing then solid light

 

Try Maplins.co.uk as they have lots of ready made circuits that might give you some directions as to they components used

I been trying to learn electronics all my life, but as yet havent made a successful circuit board to work.
