Actually it requires replacing a resistor, if you read post #38 I describe what does what.
The problem is I think your time measurements are way off. I thought the original YouTube video was to your specs, 3 flashes per second with 1 second between the flashes 3 seconds). The second was to the cop lights I have seen 8 flashes per second with 2.1 seconds rate (this works out to around .78 seconds gap per side).
There really isn't room for a pot, if I had laid it out that way it could have been done. I put a pot for the number of flashes because tolerance drift would have been a PITA.
Original
...... Your specs ................... My board
3 flashes/.5 seconds...........3 flashes/.5 seconds, each flash is 0.083 seconds.
.5 seconds gap..................1 second gap
Revised
...... Your specs ................... My board
3 flashes/.25 seconds ........3 flashes/.31 seconds, each flash is 0.0625 seconds.
.5 seconds gap ..................75 seconds gap
OK, I misread the specs a bit.
I'll drop the .75 seconds gap down to .5 seconds, but this is the last change. I've got a full day today, if you want to change the numbers a bit you have a little time. I'll do it tomorrow morning.
