Solder Station Plus
temperature control and DVM in one unit
Published in issue 395, November 2009
This article describes a low-cost energy controller for a standard 12 V 30 W soldering iron. A PIC18F4520 delivers a controlled pulsewidth modulated energy supply to the soldering iron. In addition the unit functions as a two-input digital voltmeter.
Main Features Suitable for use with 12 V / 30 W (max.) soldering irons. Temperature control using PWM. Power supplied from a low-cost 12 V /3.33 A mains adapter. Two DC voltage measurement inputs. Measurement ranges: 0 to 10 V (channel 1), 0 to 40 V (channel 2) Displays supply voltage. Microcontroller PIC18F4520 with flash memory LC display 2 lines of 24 characters (with HD44780 controller) Software calibration of measurement channels.
