Step 10Optional: Add Sides and Lighting
1 Red LED (1.7v 20mA)
1 Green LED (2.1v 20mA) - There were two in the box
1 Pair of LED Holders
1 Set of 68 ohm resistors
1 Set of 47 ohm resistors
1 Toggle Switch
1 Battery Holder (2 AAs)
Stuff you should already have
Soldering Iron
Solder
Thin solid wire
Electric drill
Hot glue or super glue
If you want to use different color LEDs or a different amount of LEDs you will need to use a LED calculator to figure out what resistors you will need. Here is my favorite. Here is another Helpful LED Link.
Take a leftover peice of hardboard and cut a side for your project. You should probably cut the other 3 sides while you're at it. I installed this on the left side of my queso dish near where Han's head is. Once you have your board you'll need to cut three holes in it. See the pictures below for more detail. The left-most hole will contain our circuit and lights. The middle hole will hold the on/off switch. The right-most hole will act as a 'drawer' for our battery pack so we can change them out.
I also cut out some pieces that were slightly bigger than the holes I cut. This allowed me to achieve a nice 'elevated' effect. Drill two holes in your left-most piece (one for each LED) and push the LED holders through them. Do the same for the switch on the middle (smallest) piece.
Glue all of these parts to each other and then glue those smaller sections over the holes in your side piece. Once you have this we'll start building the circuit.
