I've been wanting to make this project for a long time, and finally, here is a prototype!! I made a template of my fold-up house, which is exciting enough, but then I made an LED light to go in it! These are still in their developmental stages but I couldn't not share the progress with you.
My dad helped me to know what I'd be looking for if I went to Radio Shack. Indeed, I bought almost all the right stuff. I only needed a 2-battery holder, and the switch needs to be a bit bigger (the customer service guy at Radio Shack was completely useless). But now I have a clue about what I'm doing and what I need.
The light is only a few components put together: a battery pack for 2 AAA batteries, some wire, a switch, and an LED "bulb." Isn't it fun?
