Sub complexes
Present series tested sub complexes. Every from these complexes is the used in practice and works.
bistabil who changes state depending upon the length of activation of entrance
watchdog complex for the microprocessor - entrance CP, exit RESET or / RESET
MOSFET version - interrupts power supply at overload
5V power supply, with histeres, dynamics of entrances is 2-80Vp
low-cost, simple for the building in, interrupts many sets of ordinary telephones (2,3,4,5,..)
12V the complete bridge driver with protection from wrong control
constant amplitude (entrance impulse 50-75Hz, exit 8Vp)
useful complex for decrease dissipation on stabilizer 5V (150mA)
simple complex ON / OFF tastera with more advantage
good principle of synchronization of work UC3842 / 43 on the external tact / oscillator
relay complex for protection from wrong connectings of poles DC power supplies
simple complex for control switching on fan - fan switches on when achieves specified temperature
pretty solution when you subsequently needs power supply 24V, and already have power supply with stabilizer 5V
low-cost sensor of water level
low-cost optic sensor
simple timer 12V
with mosfet and TL431
Low-cost measuring RMS AC converter 20Hz..20kHz
Jeftini i jednostavni mjerač / komparator / detektor pokreta
Voltage controlled oscillator
RS232 galvanically isolated towards the microcontroller
connecting 3.3V SPI memory with 5V microcontroller
