Hello, this is my first post. I googled it, and searched the forums, but no luck. I want to know what I need to build a device, that can light a small light bulb. Something rather small, such as a flashlight bulb. But I need the on/off switch to be a photocell that is sensitive enough to make the bulb light, when a laser pointer hits it. If that doesn't make sense, think of it this way. I want a to make a small light bulb light up whenever the laser pointer is hitting the photocell. I assume I need a few batteries to light the bulb. Also, a photocell of some kind, but I don't know what kind. Would I need anything else? If I need to be more specific about anything let me know. Thanks in advance.
