Zdravim ve spolek, Zde je program na dnesek, zitrek a cast nedele, doufam, ze nektere body lidi zaujmou a pridaji se.
*** vyroba experimentalniho inkubatoru - chladice a ventilatory jiz mame, dnes chci koupit jeden ci dva peltier moduly, thermopaste a isolacni material na inkubatorovou bednu (doufejme PIR aluminium coating), dnes vecer a zitra to budem davat dohromady, zde je od kamarada design ktery chci plusminus nasledovat s vyjimkou pozice dveri, ktere jsou v jeho pripade optimalizovane pro lednicku/chlazeni, danou bednu priveze take na 30c3

Dve solid state relay nekdo nahodou nema - na spinani cca dvou 90W peltiers (pokud nekdo ma a prodal by dejte prosim vedet jak solid state relay to peltiery, usetrilo by mi to behani). Mozek a cidla davaji dohromady kluci v Holandsku a Nemecku, takze to bude predstaveno na 30c3 ci v Brmlabu pri nasi unorove navsteve
*** konstrukce pracovnich stolu - pokud se postesti, tak dnes koupime cca 200x60x2 cm omyvatelne a normalni drevotriskove desky; 4x4 a 4x2 cm sloupky a vetsi mnozstvi ocelovych profilu na spojeni materialu plus srouby a matky. Co je rozumnejsi Hornbach, OBI ci Baumax? Vsechno ma byt pospolu smerem na Ruzyn, kde bych to rad koupil abych nemusel moc jezdit. budeme v zasade replikovat toto

na obrazku je 3 m verze, tu ale do haker busu nenarvu, takze 2-2.5 m max
*** fermenty - podle toho zda se nam podari poridit cca 20-30 l plastove fermentacni kyble a nakoupit suroviny, by jsme fermentovali zaklad na zazvorovou limonadu, radi by jsme udelali par 2.5-3 l fermentu na styl Korejskeho kimchi, dle zajme by toto propuklo dnes ci zitra Nuze takovy je plan, ozvete se kdo ma zajem se pridat.

Hi all,
i dont have technical data of my peltiers. i measured 7,5a at 12v = 90w for the two together. we got a temperature difference of 20° in our 94 liter box in the negative direction. peltiers can heat much better than cool. the hexayurt material is much thicker than my BASF Styrodur 3035 CS i used. So 89 W peltier should work fine. i think a bit more or less is ok. 267 W is too much. you cannot cool the hot side with a normal cpu cooler, you need watercooling here.
your build is *much* to inefficient. try to use 2 cpu coolers with the peltier between them. one cooler inside the box, one outside. fill every hole with the insulating material. will the gap around the peltier between the coolers, too. use a larger cooler, especially on on the outside.

you can connect your electronics to the peltiers in mycooling box at thecongress and use it as an incubator prototype if you want.
