First of all, let’s see what are the parts needed for building the sous vide device:
See the pictures below
*** Other Equipment & Tools
Please see the picture below:
We wanted to use a cooker at the first place. However, when we get the following cocker, we realized it’s not easy to control the temperature if we hack this cocker (left in the picture below). Hence, we replaced it with a boiler (right in the picture below).
After getting all the tools and equipment, we hit the road of hacking.
Use a screwdriver to open the power hub, and then solder a power cord to the power hub. Please see the picture below: the red power cord has been soldered to the power hub (see the picture below), and the green circles show the point of soldering. And then put the cover of the power hub back with screws and a screwdriver.
Now, let’s solder the Grove Relay to the red power cord.
Use the insulated rubber tape to cover the Grove Relay for protection from electric shock. Please remember to leave out the Grove Connector, for connecting the Relay to Seeeduino Lotus.
As shown in the middle picture below, connect the sensor area of the One Wire Temperature Sensor to the boiler with heat sink compounds. Use insulated tape to cover it.
Plug the Grove Relay, Grove OLED Display, Grove Rotary Angle Sensor, Grove Buzzer onto the Seeeduino Lotus.
From the picture, you can see 1~4 grove cables and 2 black ables (A&B).
We use Seeeduino Lotus as the controller, its programming environment is the same as Arduino. If you have any questions about using this board, such as installation etc, please refer to the wiki page of Seeeduino Lotus. And here is the code of this Christmas Sous Vide Feast for your reference.
Let's have a look at the final version of our Sous Vide Device:
For this Christmas feast, we'd like to make the following dishes with our newly-developed Sous Vide Device: egg, beef, chicken wing and broccoli. Besides, since the theme is Christmas, we would love to add some festive seasonings (decorations)!
Let go shopping!
And then clean the food and prepare the seasonings:
We put the different food into the bags respectively and put it into the boiler for cooking. Please see the temperature and time that we used for cooking different dishes:
And voila, please have a look at our Christmas feast!
