I wanted to give my girlfriend a unique gift for Valentines Day and the idea of putting something special inside a light bulb came to me after seeing an Instructable on how to make light bulb coat hangars. I was expecting it to be a lot more work than it was. I was actually able to complete the project in the span of just a few hours, and now you can too!
The second picture is the schematic (wiring diagram). I am aware that only using one resistor for all the LEDs is bad practice but I did not want to put resistors on the LEDs that are attached to the frames because it would have looked cluttered. Since the LEDs will not be on all the time I figured that only using one resistor is not a huge deal.
Also, no worries if you are not electrically inclined. If you do not want to add any LEDs or anything, just ignore all the steps dealing with them.
Just think of all the cheesy puns you can use when you give this to him/her!
Step 1: Parts List
For this project you may need to do a little shopping. Luckily, everything can be found around the house or bought on Ebay. The total cost for the project can easily be kept under $20.
Items I Used:
- A light bulb: It does not have to be clear because the white powder on the inside of the glass can be rinsed out.
- A few feet of 18 - 26 AWG solid wire.
- Several feet of magnet wire, no smaller than 30 AWG.
- Some LEDs, I used 11.
- A 220 ohm resistor.
- A 9-volt battery.
- A 9-volt battery clip.
- A small switch.
- A picture of yourself and your significant other.
Feel free to add additional components to your design! There are a lot of different things you can do to add your own touch. For example: using a 555 timer chip to make the LEDs fade? If you're not really handy with electricity you can even just skip out on the electronics.
You may also want to buy more than one light bulb in case you accidently break the one you are working with.
