Hello,
I am a student with an interest in physics but sadly little understanding in electricity. I have some concerns about this little project i have in mind.
Given time I will gladly read through the education part of this webside, but i just made an account to get some experienced opinions.
A friend of mine told me she'd like to have a little night light, one of those who project stars onto the ceiling. So I'd love to make one for her.
My idea (of which i will attach an outline) was that i take a piece of wood (got some ash lying around) to make the frame of. In which I will cut an big hole for the top part of a flashlight for the light and another one one on the bottom where i thought i'd store the battery.
For the stars i'd go to a copy shop and let them print me some colorful tranperent foils to lay on top of the flashlight. I have some good ideas for that part.
Now for my question.
My biggest concern is if it is safe to store a battery (i'd use a 9v block or AAs) in a piece of wood. I'd really hate to burn down her house.
Would i need a resistor for this?
Some other thoughts where that i'd like to use a led flashlight (because of the white light and the low power consumption) but i don't know if they have a board in them and whether this would be located in the top part that you can take of when changing the battery, where the leds themselves are. If not then it wouldn't work when i just bring some cables to the parts where the power usualy connects. Am i right?
I have little to none experience dealing with projects like this, so I kept it as easy as I could.
Thanks to all of you in advance,
Alex
