You said you would like to build it. Is there a reason to not just BUY one? What you're describing is exactly provided by a string of solar LED xmas lights. I've picked up some strings for free at garage sales. You didn't mention solar recharging, so I guess you wouldn't need that extra function.I'm a newbie on electronics.I would like to build a project which light up around 30 LED(preferable white led) upon light sensor activation and powered up by batteries. Can anyone give any advice for how much complicated does it need to be done.
I think I've pointed this out before, but the reason to do it yourself is to learn. Either way it is not expensive, so why not do it yourself?You said you would like to build it. Is there a reason to not just BUY one?
btw,i'm from malaysia.
If the whole point is the learning and the satisfaction, then DIY is great fun. As only a means to an end, not so much. Especially if that same end is cheaply available already.I think I've pointed this out before, but the reason to do it yourself is to learn. Either way it is not expensive, so why not do it yourself?
I thought about using those,but don't really understand how it should be design. Still learning the basic concept of the timer itself. Also, i would like to reduce the number of led being used to 4 units with supply battery of 6 v hope it will simplify the circuit and prolonged the battery life.You could use 2 X 555 chips (or a 556). This design would be a lot more certain to work.
