Discharges 100uf Cap through LED at 300 mA Peak Pulse Takes 40mA peak from the supply LED is 3.2 volt 280 mA the resistor on pin 5 set the width of tOn
PNP charges C when pin 3 is low tOff set by 3 k timing resistor
NPN discharges C through LED when pin 3 is high tOn
Yellow Trace Supply Current
Blue Trace LED Current
You do this a lot simpler then this just using 555 no transistors but keep getting can't find solution error after 4 flashes
