Heater de-heater of skin Works with: The 8051 microcontroller A Peltier element (which can freeze below zero degrees Celsius) Further electronic equipment Demands: Within 30 seconds a surface of 9 square centimeters is warmed up till 37 degrees Celsius. Within 1 minute the surface is get cold to 5 degrees Celsius.     Upstairs     Vacuumlevel controller Works with: A Motorola pressure device Further electronic equipment Demands This equipment gets into alarm if a vacuum (not much) gets too low. From the pressure device we get very low signals. To amplify those signals a square amplifier is used which gives theoritically 50% reduce of noise. Tests has shown that this amplifier's characteristics doesn't change much of temperature changes (70 degrees Celsius) and the amplifier is very stable.
