If your favorite tool is a hammer, every problem will look like a nail. Abraham Maslow Given how often I tinker with the LM555 and LMC555 analog timers, Maslow might have written that famous aphorism specifically for me. And it. Well, here I go ...
In process industries, field contacts from pressure, temperature, flow switches, limit switches, push buttons, etc., are read by programmable logic controllers and/or distributed control systems (PLC/DCS) through digital input modules. They are ...
At its invention roughly four decades ago, STM (scanning tunneling microscopy) created a sensation because it was the first technology to make atomic-scale-resolution imaging a routine procedure. An essential requirement for the practical ...
I was surprised recently when a (nearly) two-decade-old design idea of mine for take-back-half temperature control ( Ref. 1 ) got a question from reader John Louis Waugaman. John says he needs a way to control the temperature of batches of rising ...
There are many circuits of soldering station controllers, but absolutely all close the temperature feedback loop using the soldering iron heater thermistor. The performances of the soldering station can be improved and the circuit can be made ...
Piezoelectric actuators (benders, stacks, chips, etc.) are excellent fast and precise means for generation and control of micro, nano, and even atomic scale movement on millisecond and faster timescales. Unfortunately, they are also excellent ...
In recent EDN design ideas, we’ve seen thermostat designs that meld the functions of sensor and heater into a single device: FET, BJT, or even a simple length of fine gauge copper wire. A virtue inherent in thermostat designs that use a ...
Conventional thermostats are based on separate temperature sensor and heater devices with means for feedback between them. But in some recent EDN design ideas (DIs) we’ve seen thermostat designs that meld the functions of sensor and heater ...
The solar panels are operating at optimal parameters when they are at the perfect right angle to the sun. Unfortunately this is accomplished only if solar panels are rotated by the sun. This is the purpose of this diy solar tracker system or if you ...
“The unfortunate relationship between servo systems and oscillators is very apparent in thermal-control systems,” said Linear Technology's Jim Williams ( Reference 1 ). Although high-performance temperature control looks simple in ...
