We can use this small LM567 calculator tool for finding the right frequency, Rt, and Ct values for our tone decoder circuit. Now we know that this IC works on one simple relation which is, f = 1 / (1.1 × Rt × Ct) So we can see that this frequency depends only on the […]

RC Snubber Calculator for MOSFETs, Relay Contacts and Triacs
This calculator is basically finding out two things: …so that we can make a perfect RC snubber for killing high voltage spikes across: Now let us break down everything it’s calculating. RC Snubber Calculator Application Type: MOSFETTRIACRelay Contact Peak Voltage (V): Peak Current (A): Rise Time (µs): Calculate Snubber © homemade-Circuits.com Basic Snubber Formula Logic […]
Shunt Resistor Calculator for Ammeters
Ok so here we have one simple calculator which can help us to calculate the shunt resistor value that we need to connect across a normal ammeter when we want to use that ammeter to measure high current, more than its actual range. So normally, ammeter can measure only small current, like 1 amp or […]
SMPS Flyback Boost Converter Calculator
This calculator tool supports a Boost Converter Flyback setup which means now the code considers: Corrected turns ratio and primary voltage logic since the flyback works by storing energy during “ON” time and transferring to secondary during “OFF” time. Flyback boost topology where output voltage is higher than input. An accurate duty cycle formula for […]
