Hi guys.
I have a 445nm build using a single 18650, the current is set to 1A , the microboost gets very hot very quickly...and after 30 seconds, starts pulsing...any ideas why? do i need to limit current going IN to the microboost?
TIA
How do you have it wired?
What is the brand and mAh rating of the battery?
That pulsing is usually a power supply problem
Peace,
dave
Its inside one of jayrobs 18650 hosts.. the battery im not sure about, it came out of a laptop battery pack, but that same battery performs flawlessley in my 290mw 532 for as long as i ask it too. And tbh, i think the pulsing is the mmicroboost overheating and shutting down.
The pulsing is usually caused by the battery voltage dropping below the input threshold. It can also be caused by voltage drops across all of the small resistancs in the circuit such as metal-to-metal contacts. The biggest culprit I've found is those cheap clicky switches. Use an accurate Ohmmeter and measure across all these points - when you find the culprit, it will be obvious. Try the clicky switch first. Bet you that's the problem.Hi guys.
