We used a Kniwwelino and a Arctic F14 PWM fan. The cool thing about the Artic PWM fans is that you don't need any power transistor to change the fan speed. You just have to add a PWM signal to the forth pin of the cable and you are done. To have 12V for the fan I use a step-up converter that comes with a handy micro-USB connector. text/html 2018-06-28T09:41:34+00:00 Anonymous (anonymous@undisclosed.example.com) https://doku.kniwwelino.lu/en/communityprojects/pomodorotimer?rev=1530171694&do=diff Pomodoro Timer A timer with a duration of 25 min to be used as part of the Pomodoro Technique.
