Page history last edited by PBworks 13 years, 11 months ago

Me and Colin are going to make a lie detector.

 

We are going to follow aaron cakes plans at http://www.aaroncake.net/circuits/lie.asp

 

We printed off the sheet.

 

Success with this device will be being able to find out whether somebody is lieing.

 

 

The schematics with a labeled part list below.

 

Part Total Qty. Description

R1 1 33K 1/4W Resistor

R2 1 5K Pot

R3 1 1.5K 1/4W Resistor

C1 1 1uF 16V Electrolytic Capacitor

Q1 1 2N3565 NPN Transistor

M1 1 0-1 mA Analog Meter

MISC 1 Case, Wire, Electrodes (See Nots)

We have all the information we need from the link above.

 

Documentation will be updated...

 

We decided the lie detector will be too hard so we will make a Altoids Tin Speaker.

We will follow Ken Kirkpatrick's plans to some extent. We want to amplify the sound so it will be louder. Success will be measured by whether or not it will be loud enough and work as a speaker.
