Step 1: Ingredients:
This is our first Instructable so we decided to keep it simple. These are the parts you will need in order of importance. Feel free to substitute any of these items for what you have available to you of course why even bother making it if you’re going to be like that.
1. A Holy Relic: We chose a fine paraffin candle from our local pharmacy. While obviously a reproduction it will still bestow luck and fortune to your device.
2. A Project Box: It’s like an Altoids tin for someone who wants what they are working on to look good and not smell like a curiously strong piece of crap.
3. A Battery: We chose a 9-volt in case this device functioned properly and we were attacked by a roommate or loved one. The added weight of the battery will make the Headache machine more lethal if thrown in the vicinity of a person’s face or groin.
4. A Battery Harness: You could just solder the leads directly to the battery. You could also cut your own hand off if you really wanted to but just because you can do something doesn’t mean you should do it.
5. A Switch: We chose a 12VDC Toggle Switch with Safety Cover. While you can purchase these at your local electronics retail store we recommend springing for the “real deal” and getting one out of a Soviet era Mig fighter. It’s really worth the extra effort.
6. A Piezo Buzzer: This is also known as a Piezo Speaker. We chose a 76dB 6-18VDC buzzer. This guy is a nice balance of price, size, and obnoxious noise. You could mount two or more buzzers or batteries to influence frequency and output. We were going to hook this device up to a scope to get more information but instead we ate birthday cake.
