Welcome home!

Good morning!
I've finally put the electronics into its housing:

I removed the sockets on the relay board and soldered in the cables directly. Then I made those brown bridges to simplify phase supply. Eventually I hot glued the arduino and the board in their respective places and made a hole in the top cover to grant access to the usb connector. What a fun with a screwdriver and a scalpel... :)

I also opened the washing machine, removed the supply cable and the hoses and tried to identify the different parts. Heating, pump, motor and solenoid valve were easy to find, how I predicted. However theres this red thing:

It almost must be the level sensor, since theres only one hose going to it. But damn, all those cables?! Further investigation will be necessary. And theres a wire coming out the drum I've no idea what it could be.

And unfortunately, there are tons of white cables in that machine, without any labels of course. I spent hours and hours over those damn schematics without really finding out what I could safely bridge without killing the electronics and thought that I'll move further when I see it. Nope. White wires. 

For the moment, everything is only super provisionally and in an experimental state, I try to not damage anything so if the beer brewing really shouldn't work I can still wash my clothes with it. So I now disconnect everything and control every component myself. To replace a solenoid valve or an other small part would not be the bad like the whole electronics. So I bought a fault current switch and made a cable with a switch and two sockets and I'll start testing today part after part. 

I also pulled out the motor and searched the interwebz for a method to hook it up. Well.

There are two red wires for the speedometer, a blue and a white for the rotor, a brown and a green for the spool and two black I've no idea. :) So I went to a friends top secret quadricopter drone laboratory and hooked my motor to a adjustable AC power supply. The phase to one end of the spool, the other end bridged to one end of the rotor and its other end to neutral. A deep breathe, 50V and it works! 100V, 150V, 200V - like a charm! So I ordered some TRIAC thingy to regulate the speed of the motor. I'll build two of them with potentiometers into my electronics box for two speeds, one for normal brewing and the other for spinning, controlled by two relays. I wonder if that is going to work... :)

I'll try to be back soon for results on the other parts. 

Although I know about the dangers of playing around with 230VAC and try to work as safe as possible, like with a fault current switch, fuses and good isolation, theres still a risk. 

So if I don't come back here, you know I died for the good cause and I hope you'll celebrate me as beer hero! ;)
