Philips PerfectDraft serves an excellent glass of beer, however, in my opinion the beer is too cold.
The unit serves beer at a fixed 3 degree Celcius. I slightly modified the device in order to be able to adjust the temperature between 3 and 10 degrees Celsius (or 37 and 50 Fahrenheit). The PCB cannot be changed easily, but it is easy to put a potentiometer combined with a switch between the temperature sensor, an NTC, and the PCB. The higher the combined resistance of the potentiometer and the NTC, the higher the resulting beer temperature. A switch is used to short the potmeter to be able to restore original settings but also to read true temperature.
Philips PerfectDraft, prima apparaat maar het bier is naar mijn smaak, zeker in het koudere seizoen te koud. Een potmeter in serie met de NTC geeft de mogelijkheid het apparaat om de tuin te leiden en de temperatuur te verhogen.
Повторяем попытку...
