Changes:

The mirror will no longer be usable by touch. The touch overlays are just too expensive. We are currently considering which alternative is the best, if its buttons ore some kind of a mouse interface or something completely different.

Mechanical:

The first parts are finished. After 3D printing them they needed a little finishing as the piston and the cylinder didn’t fit as smoothly as they should. So Youp grinded the it by hand into our required measures.

To make the project a little nicer we decided to use two different kinds of movement for the toothpaste dispenser (TD) and the door opener. At first it was planed to use a 180º servo for the TD. Now we will use a 360º servo. This gives us the opportunity to move the piston more precise. With our first approach the pushrod hat to be all the way lowered within 180º so we were very limited.

More details will follow.

Arduino (Bene):

Fitting the relay was more complicated then thought in the beginning. At first I had to get more theoretical knowledge about how it is working. Now with some help I was able to add it to the circuit so that we can start it by pressing a button.

Due to the decision of changing the movement for the TD the coding has to be changed as well.
