DIY CIRCUITS ELECTRONICS

new project - video ATmega SolderingStation in this video im presenting a soldering station i built that takes advantage the quick heating t12 tips. it uses very cheap components that are easy to find.you may built it either using an arduino or using an atmega chip,pcb & firmware provided in the project page. schematics-firmware-pcb and info here https://easyeda.com/wagiminator/z-sol... this video is NOT sponsored by any company.i just built it and if anyone is interested can built it too since it is open source. soon im going to make a second video showing the menus and calibration procedure with more details.

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
