Hi, first post.
I have built some cycle lights, they work well using the new Cree R2 emitters. I run these from an external battery through a constant current driver (Buckpuck) the driver has a "control" pin 0-10v and I have wired this into a potentiometer.
It all works great and the light will dim from 100% to zero.
My question is, can I use a IC-Timer instead of the potentiometer?. I mainly want this as I have read that the pot resisting the flow from the battery is power wasteful and far less efficient than an equvalent IC would be.
I have watched the utube vids on 555 timers and it seems ppl are using them in conjuction with a pot to strobe the output, how does this overcome the pot's inneficiencies, I'm confused.
Thanks
Dave
