Step 2Parts List
To build this amazing time machine you'll need:
1. An old, broken transistor radio. This Instructable is for a side-dial thumb wheel model, but you can build one with a center-dial unit too by getting creative with the switch and LED placement.
2. A sound card that records and plays back audio. For this project, I used a dual-sample circuit board from Electronics 1-2-3 that costs $7.55, here's a link: http://tinyurl.com/cpbtyk .
3. Two LED tea lights that flicker with an amber glow.
4. Solder and solder remover or wire braid.
5. An eight inch length of 9-conductor ribbon cable or equivalent. Easily removed from any broken computer. I like the rainbow colors for easy wiring and a pretty look if someone opens the case.
6. Two 3-Volt CR-2035 dime batteries and holder. You can sometimes re-use the batteries that came inside the tea lights, as well as the battery holders if you want to trim them down and connect them together in series for 6 volts. Otherwise, good prices on eBay. You could also go with the original 9-volt battery instead and put in a voltage regulator circuit to bring it down to 6 volts. I chose to keep things simple as the current draw is minimal.
7. One 3/4 inch nylon bushing or two washers glued together for greater thickness.
8. Goop or Shoe Goo brand adhesive with applicator tip cut to smallest opening.
9. Electrical tape.
10. Masking tape.

why not recreate the radio box then put in a real working transistor radio? it would be hard for other diyers to find the same radio as you're using
