Project development

This week is the project development. I will summarize the progress of the project, what remains to be done and also what has not worked as expected.

Completed task and remain task.

Tasks completed.

The design of the wooden frame is finished.

The design of the bottom container is finished.

The design of the top container is finished.

The design of the peristaltic pump is finished.

The light board is a designed.

The main board is a designed.

The motor stepper drive board is a designed.

Components are ordered.

Laser cutting of the wooden frame is complete.

The peristaltic pump is assembled.

The code is finished.

Remain taks

To assemble the wooden frame.

Design the distance sensor holder.

Design the light and light sensor holder.

To print the distance sensor holder.

To print the light and the light sensor holder.

To solder the light board.

To solder the main board.

To solder the stepper motor drive board.

To wire the different sensors.

To print top and bottom container.

To test the program.

To assemble all parts together.

Film the video of the project.

Document the project.

What has worked? what hasn't?

Everything that has been done so far is working as expected except for the peristaltic pump. The problem is that I forgot to leave a space between my two moving parts. This causes the two parts to insert one into the other but much too tight. I must therefore reprint the outer part with a distance between the two parts of 1 mm. This will reduce friction between the two parts.

What questions need to be resolved?

The only question I have right now is I'm not sure if I will have a water resistance problem for the water containers.

What have you learned?

The most important thing I learned that answers my question from week 13 is how to design a stepper motor drive. It's a big part of my project and I'm glad I learned that. I also learned how to design better in Fusion 360 with several components. In the pump project, I had 4 different components and 11 components in the water dispenser. I learned how to align the parts properly with each other and also how to work well with several components.
