DIY Soldering station [Part 3]

Power supply: This soldering station need to be efficient. I will choose switch mode power supply. The circuit will have 2 power inputs: from 24V AC though a rectifier or 19.5VDC from a spare laptop power supply. I prefer the laptop power supply since it will be safer to use and output voltage will be… Continue reading DIY Soldering station [Part 3]

DIY Soldering station [Part 2]

Design requirements: Power supply: It could be used with many sources of power supply: 24VAC, 24VDC or below. Power control of the heater: using MOSFET to switch on and off supply current through the heater with PWM signal from Microcontroller to modulate the MOSFET. Display: Using a 4x7-segment LEDs. Actually, I will use the 5461BS… Continue reading DIY Soldering station [Part 2]
