19. Project development

Complete your final project, tracking your progress:

  • What tasks have been completed, and what tasks remain?
  • What’s working? what’s not?
  • What questions need to be resolved?
  • What will happen when?
  • What have you learned?

Responding to Project information¶

What tasks have been completed, and what tasks remain?

Complete tasks

  • Identifying and thinking about the need
  • 2D and 3D structure
  • Single sided PCB (for sensors and controller)
  • Parts found, some local and some purchased on AliExpress (ATTiny44 microcontroller)
  • Assembly and connection of the parts according to the original design.

Remaining tasks

  • Tank level control software.
  • Testing and calibration if necessary.
  • Filming process and documentation.
  • Previous final presentation

In the list we can see our progress to 90 %:

What’s working? what’s not?

What works

  • Detect the water level (high level and low level).
  • Turn on the water pump and turn it off
  • Read data from non-contact sensors
  • LCD display works correctly
  • ATTiny44 PCB works properly
  • Manual faucet does not drain water from the tank.
  • Tank module fits exactly with the fittings

What doesn’t work

  • I need to improve the project program.
  • The video of the project is still in the process of being made.
  • The connections and cables are loose, I need to tidy it up for better presentation.

What questions need to be resolved?

Two things: The filling and emptying time of the water tank and the consumption of the water pump motor, according to the manufacturer it says 12V, 2A. I need the real consumption to supply a source that supports this current when the whole system is running.

What will happen when?

If it fills the tank too slowly, I should look for another water pump that has a higher flow per minute. I have a 1.5 A source, if necessary I should replace it with a higher amperage source, probably a switch type source which are small and light.

What have you learned?

In the last weeks I have learned a lot! The electronic hole making productions with the Monofab was very new to me, also the topic of CNC milling was something I hadn’t used in conjunction with the laser cutter. What I learned the most is time management, for my next bigger project, I have to work on my time management! A lot of things were done at the last minute, resulting in a lot of stress and moodiness....

But I really enjoyed it nonetheless, and that’s what counts :)
