[Help] 555 IC Keeps Blowing Up

i attempted to set up the 13005 based dimmer when i realized that the common collector e.g. an emitter follower setup is not good for current limiting/regulation

• you can always make sure your led-s not over loaded by choosing the proper resistors **for max Vcc
• but it's likely more reasonable to build your thing up from 2 modules
  1. a dimmer (generating proper waveform for ↓2.↓)
     
  2. a led switch (controlling the LED-s current) -- would also ensure enough brightness running from battery only**

as your next concern may turn out the LED-s not holding up
