30 Second Led Timer

[kermit911]

Hello everyone, I am trying to build a small led strobe for an old fashioned photographer flash. The old flash they used to use with gun powder back in the day, it is going into a Christmas Village. I am using white led strips with an inverter and a power supply that plugs into the wall, but I can't find a speed controller for the timing of the flash. All I need is for the LED's to flash for a split second every 30 seconds. Any ideas?

Thanks
Kermit

Sorry I forgot to mention that it is 12V 300mA LED's

This will do the job with slight modification:-

If you click on the link to the technical data sheet, you will eventually see the circuit diagram. If you change the value of R1 from 1K ohm to 220 ohm, it should give you the timings you require.

Bear in mind that this is a kit that need building with soldering etc.
