Tasks for the week:
Bene
- Change the code for the load cell, so that the led doesn’t bright up until a certain level eg. 10 but then if it reaches a further interval of 5 the led shall bright up
Andre:
Find the Name of the material
Youp:
Check how the hinges on a laptop work
Jony:
- find a powerbank
- do we need a further powersupply?
Progress:
Mechanical, Electrical and Computer Science
We all together tried to find the right motors for our moving parts. So we tried a 180º and a 360º moving stepper motor. The challenge is to transfer the movement so, that it produces a steady amount of pressure that presses the toothpaste onto the toothbrush and stops, as soon as the load cell gives a signal to the motor, that a certain weight is reached.
Decision:
- idea to make the hole mirror-box for holiday purpose. gives us a nice benefit
- little amount of toothpaste needed => design gets smaller
- we want the box to be portable. this results into the question of how are we going to power the box?
- Powerbank?
- laptop flip design: open the flip to see the mirror
- make the screen around 13 inch
- height of 8 to 10 cm
These decisions were made on the 12.09.2017 in the group-session. It was important to agree on a first design so that Youp can start with the CAD drawings of all the mechanical parts, because these need to fit into the box.
Also we decided to build the first prototype from plywood, using the laser-cutter. Wood is easy to work with, its light, it will look good and the production of the parts is very fast.
But we are thinking to use elements out of metal and plexiglas as well, just not for the first prototype. These parts we want to produce if we really know how to put everything together so that we don’t have to produce the parts several times.
