The cooling program on node-red |
Some screenshots of the 8°C tests and settings |
I am back full throttle for the final straight of this great adventure. It will be very intense. I received waterblock and a circulator in addition that I installed. I finished assembling all the wood part to be able to fix all the electrical elements correctly. Following this I performed a test with a setpoint at 8°C. I notice that it works pretty well. I am waiting to receive a controller to be able to drive the TECs with a PWM output of the Raspberry. I will also drive the fan in PWM to make it run slower so is less noise. It will probably enslave on the temperature of the hot circuit using a PID.
For those who want to see how my program works on node-red here is the version that is currently in place :

I started by installing the "distribution" part (the pumps at the top left). Now i’m installing the containers that will contain sodas. will soon be doing a test with the copper coils that will soak in the cold water (as for a beer shooter). I'll talk about it in a future post.
This weekend I will make the furniture in a carpentry workshop. This will allow me to have a much better finished device. With all the components inside the furniture and a bent tube for "distribution".
This project is a big part of my time right now. One thing is sure : if there had not been this contest I would have never been so far in making this device.
