Pro \u0159\u00edzen\u00ed varny jsem ji\u017e postavil a pou\u017eil n\u011bkolik elektronick\u00fdch syst\u00e9m\u016f a softwar\u016f, nap\u0159. Brauanlage, BrewControl4Kreuzer, Ardbir i Raspberry Pi3 & Craftbeerpi. Ka\u017ed\u00fd syst\u00e9m \u0161lo nakonec pou\u017e\u00edt, ale v\u017edy pro mou pot\u0159ebu vy\u017eadoval n\u011bjak\u00e9 \u00fapravy. Nedopadlo to ani s nad\u011bjnou Malinou a Craftbeerpi. Autor se tv\u00e1\u0159il a prezentoval st\u00e1l\u00fd v\u00fdvoj, ale asi p\u0159ev\u00e1\u017eily komer\u010dn\u00ed z\u00e1jmy a v\u00fdvoj p\u0159estal publikovat. <\/p>\n\n\n\n

\u0158\u00edzen\u00ed je postaveno na obvodu ESP 8266<\/strong>. Tento obvod obsahuje WiFi a je \u0159\u00edzen z programu na PC. Zad\u00e1vaj\u00ed se jednotliv\u00e9 rmutovac\u00ed kroky, teplota a d\u00e9lka prodlevy, lze zadat n\u011bkolik korekc\u00ed i kontinu\u00e1ln\u00ed oh\u0159ev. Pr\u016fb\u011bh va\u0159en\u00ed lze graficky zn\u00e1zornit. Jednotliv\u00e9 recepty lze ukl\u00e1dat a i b\u011bhem va\u0159en\u00ed modifikovat.<\/p>\n\n\n\n
