  1. I have just seen this message on twitter informing about the official launch of the Swid Premium, the Addelice immersion circulator that can heat up to 2,400W. Amazing!
  2. A switching power supply is one that converts AC to DC power. In the case of this product, it will also need to switch from 240V as well as 110V. Think of the switching power supply that sits between the power cord and the cord into your laptop computer and you get the concept. How does this tell us that the controller is in the external box? Because nomiku needs 7 cables to wire the body of the Nomiku to the "power box". You don't need 7 wires for power. Don't you? "We’ve had a few major challenges over the last few weeks. One of them has been sourcing a power cable with multiple conductors (we needed 7) to go from the body of the Nomiku to the switching power box."
  3. I am afraid Franz Wagner AND Diggindogfarm are both right. If you have a look at Nomiku's blog update http://blog.nomiku.com/post/46515241903/major-project-update-vii-ul-etl-csa-ce it is clear that the "power box" is in fact a "switching power box": "We’ve had a few major challenges over the last few weeks. One of them has been sourcing a power cable with multiple conductors (we needed 7) to go from the body of the Nomiku to the switching power box." In other words the temperature PID controller is located in this box. The function of the "body of the nomiku" (the stick) located in the pot is limited to setting the temperature, heating with the heater element and stearing the water with a motor. Therefore the critical parts (PID controller) are located out of the pot far away from the heat and steam of the waterbath (as supposed by Diggindogfarm). The design of this sous vide equipment is exactly the same offered by Freashmealssolution with its Freshmealsmagic http://freshmealssolutions.com/index.php?option=com_content&view=article&id=70&Itemid=100083 I totally agree with Franzwagner, Nomiku is just another external PID controler composed of 2 components, one immersed heating part and an one external temperature controler. You can't put the Nomiku in the class of immersion circulators. In term of communication it is obvioulsy best for Nomiku not to emphasise on the genuin design of their machine. You can call this "dolus bonus".
  4. Hi, I made a post on my blog about the Sousvide Supreme and readers made some interesting comments about it. To sum up, the first reactions was to says the Supreme is technically not better than a Sousvidemagic appliance (Fresh Meals Solutions) but just looking better and twice its price. Some people also mentioned the capacity of 8-10 liters of the pot excludes professional use but this is ok as the target of this machine is home cooks. The last comments relate to the precision of the Supreme and most of the people consider a PID controlled water bath cannot be as good as an immersion circulator. In my opinion the Supreme might be a very good product but as the Sousvide Magic takes a lot of place in a kitchen. I tried some month ago an immersion circulator from JULABO (the ED one) and found out such machine was outstanding. I am now testing a new immersion circulator from a company called Addélice which is also working extremely well. This thermal circulator is sold at € 449 including everything. In my opinion, if you have a little bit more money to spend, just buy an immersion circulator. Jean-François
  5. KennethT, I checked the manual of my Julabo EC and I can't find any tune function. I also searched on google for "Julabo EC PID tuning" but could not find anything relevant. It seems Polyscience 7306C manual cannot be downloaded from Polyscience site. Could someone tell me if the Polyscience 7306C benefits from tune or autotune functions? Jean-François
  6. KennethT, I agree with you. The temperature controller of an immersion circulator (such as Julabo and Polyscience) has a fix parameter which cannot fit to all kind of water volume. Therefore the PID will never be 100% optimized. Do you know if an automatic adaptative temperature PID controler (according to the amount of water) is sold on the market? Jean-François
  7. Bob, Thanks for your answer. I'll be pleased to receive your document (info((a))sousvidecooking.org). By the way I found a very interesting information on polyscience site http://www.polyscience.com/lab/7306.html Down the page is indicated "*Temperature range and stability vary depending on bath volume, surface area, insulation and type of fluid. Notes: Performance specifications determined at ambient temperature of 20ºC/68ºF." I understand "temperature range" = "temperature precision". Should we also have to conclude that Polyscience machine cannot assess the quantity of water contained in a container, the ambient temperature...and therefore Polyscience can't guaranty temperature precision? Jean-François
  8. Question about precision of immersion circulators. I am trying to compare immersion circulators available on the market and most of the trademarks are talking about temperature stability. For example Polyscience on its main page indicates for 7306C stability +/- .09°F +/- .05°C but I don’t think this is relevant. What is the point being +/- .09°F +/- .05°C stable if your are not at the right temperature. I read that measuring temperature in general was a major issue and to reach a precision of 0.3°C you need exceptional and expensive equipment. What is therefore the technical criterion to look at temperature precision in order to compare immersion circulators? Jean-François
  9. Hi everybody! True or not...there is a site that has announced some days ago launching mid August an immersion circulator designed and manufactured by an unknown trademark: Addélice. Their site is not talkative about their product but they said it will be price competitive compared to similarly immersion circulators available on the market. Wait and see... Jean-François
  10. You are right, this is a lot of money and I am not interested in bying the Roner Compact. I just want to understand how the Roner Compact works. And I have to say that nowhere is written that Roner Compact contains a PID controller. Not even inside the manual. Therefore why should this machine be as precise as mentionned everywhere and...so expensive?? Jean-François
  11. Hi, I am a beginner in sous vide cooking and experimenting most of the techniques available. I started with the cheapest technique such as gas and halogen stove. I am now cookingwith a basic water bath (bain marie) I purchased recently. Cooking sous vide works with such equipment but the range of temperature variation is significant (approx. 5°C or 41°F). I tried to compare my water bath with the ICC Roner Compact and realised that this machine does not benefit from a PID controller. The manual of ICC Roner Compact indicates: Stability: +- 0.5°C Homogeneity: +- 1% Margin of error: +- 1% I have difficulties to believe that the Roner Compact is such a precise machine. I agree that their are differences compared to my basic water bath: the heating element in located in the water and their is a water pump but I can't believe this makes such e difference if you don't have a PID temperature controller. Is there a cook among you who purchased the ICC Roner Compact and could confirm how stable is the temperature? Thanks for your help!
