Introduction: The Beeper
A little device that constantly beeps.
Step 1: Explenation
If you turn the pointiometer (Variable Resistor) the beeping will go faster/slower.
Step 2: Materials
1. 555 timer chip
2. 220r resistor
3. 50k variable resistor
4. 36uf capacitor
5. 5v piezo beeper
6. breadboard
Step 3: Hook Up
Now you just build the circuit from the (messy) diagram.
Step 4: Finish
Now just power it and it should start beeping.

I got it from a chinese service called taobao.
It's also on ebay for $3.44 each

Can you orient your circuit diagram so it isn't a mirrored flip of what you made? Thanks for sharing!
