ADJUSTABLE TEMPERATURE SOLDERING STATION
this is the first test video i uploaded to my new youtube channel so please forgive the poor quality of the video. in the next videos im making i will provide a more detailed presentation and HD video of this project. if you don't wanna miss it please subscribe . ------------------------------------------------------------------------------------------------------------ this is an adjustable temperature soldering station using arduino uno or pro mini to sense the temperature and control the soldering iron. this circuit-project is used many months now in my workshop.i built 4 of them and gave one as a gift to a friend and all of them work flawlessly. the solder iron used is a cheap hakko clone which uses a type k thermocouple for temperature sensing. notice that i didnt use the L7809 regulator shown in the schematics because it was geting too warm.instead i used a buck converter for the 9 volt output for the lm358 and then a L7805 regulator to power the arduino.you can a
