I would mock up output ckt first, LEDs, 5- 4 ohm 1/2W Rs, 10,000 uF worth of C's & 4 batteries. Charge up Cs, disconnect battery, dump Cs into paralled LEDs & Rs to see if brightness is as desired.
Buy a solderless breadboard to test out timing & flashing.
Had a few 2200 uF @ 16 V caps, only 22.2 mm long, 12.2 mm dia.
Except where noted all R's 1/4 W.
Think I would modify GopherT ckt. input to trigger on power-up.
How are you fixed for measuring instruments?
It's a start, open for review.
