Temperature controllers

• Thermostat - uses a thermistor for the temperature sensor and controls a relay    Rate this link
• Thermo-Fan To Keep Your Amp Cool - fan controller which controls fan based on temperature    Rate this link
• Temperature programmer uses digital control - digitally controllable circuit useful for precise, repetitive temperature control of small-volume objects, generates no RFI and controls mains load    Rate this link
• Temperature Monitor - a heat activated sensor    Rate this link
• Temperature controller keeps IR detector at 8??K    Rate this link
• Temperature controller drives Peltier cooler    Rate this link
• Proportional thermoregulator synchronizes to line    Rate this link
• Hautomakone vanhasta hellasta - temperature controller based on PC, text in Finnish    Rate this link
• Enhanced temperature controller is both fast and precise - Today's industrial applications demand both speed and precision in temperature control. An improved temperature controller meets those demands by adding features you don't find in traditional PID controllers.    Rate this link
• Electronic Thermostat and Relay Circuit    Rate this link
• Controlling the temperature of fiber-optic lasers - Thermoelectric-cooler-based temperature controllers have some unusual requirements. They account for circuit- and thermal-design characteristics to provide climatic pampering for temperamental lasers.    Rate this link
• Controller provides closed-loop temperature regulation    Rate this link
• Constant Temperature Circuit - This circuit is great for stabilizing VFOs and other sensitive electronic circuits    Rate this link
• Amplifier Thermal Protection and Shutdown Circuit    Rate this link

Timer circuits

• Time Delay Relay - when activated by pressing a button, this time delay relay will activate a load after a specified amount of time    Rate this link

Switching circuits

• Modular Relay System - simple transistorised relay into which can be plugged 'personality modules' to turn the base unit into a timer (pulse, delay on energise or delay on de-energise) or a latching relay or whatever is required Other circuits    Rate this link
• Load Sensing Automatic Switch - apply power to the entire audio system by turning on one item, simple circuit    Rate this link
• Impulse changeover switches - electronic switch which changes state each time it gets an impulse    Rate this link
• Current sensing relay driver - contacts relay when current flows on sense wire    Rate this link

Other circuits

• Short dc power-line pulses afford remote control - If you face the challenge of adding a second, independently controlled light source to an existing ceiling lamp controlled by a wall switch, you may find that stringing a second power line is impossible. This design uses remotely controlled control circuit located at the lamps' site.    Rate this link
