Simple Renard Strobe Burst

Thanks Mactayl,

Just to double check: if you supply the board with a constant 5v DC to the 5v pin, and the STR pin. The strobes start flashing, correct?

Correct

Awesome, I can make that work in lots of different ways!

My other question was about using different LED's, ones that are sourced in the USA (to get faster shipping). From looking at the schematic, it looks like I would just change R1 to whatever value I needed to obtain the current required for the different LED.

If this is correct, how much current can the board handle? What if I bought 1Watt LED's? (I'm assuming that is a definite no!) But what about just doubling the LED's? Using an LED current resistor calculator I get:
Desired: 2 LED's in Parallel, 5v power supply, 20ma per LED.
Results: use a 50 ohm reisistor.

But can the Board and components handle the current?

At this point in time the components draw about 11ma and the 4017 counter's outputs can't handle 1watt LED's, I would have to re-design the board with high power transistors for something like that and I am wanting to keep it as simple and cheap as possible.
