This Instructable WILL NOT cover the how-to's of mic element choice, mic wiring, or soldering, although you will need to know all of these things. For info about soldering, search around here, you'll find plenty of instructables on how to solder! (eg: http://www.instructables.com/id/How-to-solder/). For info on mic wiring, see this instructablehttp://www.instructables.com/id/I-Mic-Harmonica-Microphone/ . For more info on mic wiring (including videos) as well as mic element selection, check out my other harmonica microphone instructable http://www.instructables.com/id/How-to-build-your-own-harmonica-mics/.
Let's get started!
Step 1: Get the parts together.
Next: You will need the following items to complete this project:
1) A 1 and 1/2 inch diameter "slip on" PVC endcap (from the plumbing section of your local hardware). This will form one half of the mic shell.
2) A 1 and 3/8 inch diameter metal fence post cap (From the garden section of you hardware store). This will form the second half of the mic shell.
3) A package of 1 and 1/2 inch diameter rubber "cups" (for putting under you kitchen table's legs)
4) A 10 to 100 K ohm log taper potentiometer (for the voloume control, you can get these at rat shack)
5) A 1/4 inch mono panel mount guitar jack (again, rat shack)
6) A microphone element of some kind (mine comes from an old AudioTechnica ATR30 microphone I got used at Savers for $3.99. New it will cost around $30. You can use any element you like for this project)
7) Some hookup wire, acid-free solder for electronics, and some electrical tape.
8) Optionally: some cotton balls, spray paint, an old dryer cloth or other piece of cloth, a knob for the volume control.
