Step 1: Materials
- The shirt was made from a graphic I "found" online. It was re sized so that the LED's would be proportional to the car. I had it printed through an online t-shirt printing store like CafePress.com. Sorry, I can't share--copyright issues and all that.
- The sound recorder is not very loud but adds a nice touch. It came from Radio Shack. http://www.radioshack.com/product/index.jsp?productId=2102855
- Wire and two 9 volt battery connectors
- Gorilla/Duct tape
- Plastic card
- Hot glue
Step 2: Assembly
Carefully cut the LED scanner section out the shirt out.
Cut out the same area of a plastic card or other ridged mounting material you want to use.
Hot glue or fabric glue the mounting card to the shirt and trim as necessary.
Cut and rewire the 9 volt battery wires from the scanner and sound recorder down to your pocket or other battery holder.
I thought the LED's were too bright. To tone them down I painted them with red model paint.
Download the Knight Rider or KITT sound track of your choice and record it on the sound recorder per instructions.
Duct tape the scanner and recorder to the plastic card any way you can. Mine is not pretty but it works. You can't permanently connect them because you will eventually have to wash the shirt. Seriously. Wash your clothes. Girls can get over the Knight Rider obsession, but not the stink.
