Hey team i need some simple electrical engineering advice. I am a surgery resident and I need battery powered LED that flashes at 8 times a minute. Research funding is about as easy to find as health insurance so I am trying it on my own. I thought about just taking apart a flashing light that I use when i ride my bike to work but I am not sure conceptually the mechanism for changing the rate of the flash.
Project requirements:
- small (about the size of the old school plastic rings out of the 25 cent machines)
- battery powered
- 8 flashes per minute
- duration of flashing 2 hours max
I am thinking that I'll just build the circuit on a hinge so that when the attachment site is expanded to a hemisphere it completes the circuit and the light begins to flash. Any thoughts would be great. Especially on the timing mechanism.
