Greetings!
I'm very new to circuitry and am trying to create a LED flasher for my motorcycle helmet.
Custom printed circuit boards are not that expensive anymore, so I am hoping/planning on going that route, perhaps with a 555 chip. What I don't know is a good method of increasing the 3.7v batt voltage to the 5v the LED strips need, as well as how (which resistors, capacitors) to use with the 555 to make the LEDs flash twice at the start of every second (a 'flash-flash . . . flash-flash . . . flash-flash' kind of thing, one double-flash per second).
If this is even possible with the 555. Is there another, better-suited chip?
I have 5v LED strips that I can affix to my lid, and some 3.7v batteries. I have some parts from SparkFun that can almost do what I want (a 5v boost converter, connectors, etc.), but not quite. My research/circuit simulator/calculator efforts have been less than optimal. Any assistance would be greatly appreciated.
