17. Project Development

Assignment:

Q&A

Q: What tasks have been completed, and what tasks remain?

  • A: At this point, my Time of Flight sensor and LCD are working, programmed, communicating, and have a board completed for them. The LCD also has its casted case. The box parts have been CNC-ed and are pretty much ready to go once the electronics can get installed in them. The big tasks remaining are getting the solenoid lock working and communicating with the keypad matrix. Also system integration/wire management needs to be completed.

Q: What’s working? what’s not?

  • A: Just about everything’s working except the solenoid lock. I ordered the necessary parts and they will arrive in a day’s time so that I can get it working.

Q: What questions need to be resolved?

  • A: How does the solenoid lock work? How do I communicate between the solenoid lock and keypad matrix? How do I format the presentation video and the slide?

Q: What will happen when?

  • A: I will 1. get the CNC box together 2. get the solenoid lock working 3. install all electronics/hardware in the box and 4. system integrate/manage wires/make presentation + video

Q: What have you learned?

  • A: So so much. The biggest thing I’ve learned, though, is that the last 20% of the project takes 80% of the time. I’ve also learned a lot about electronics and finally seem to have a decent grasp on them.

Planning Schedules

System Diagram & Gantt Chart

I created this system diagram with Lucid App to help visualize what needed to be done in each step of the process for my final project:

Below is the Gantt Chart I made so that I can stay on track and complete my final project:

At this point, I am fairly behind with my schedule; however, finishing is still very possible. My current To-Do list is as follows:

Box:

  • Instal hardware inside (hinges, adjustable shelving stuff, etc.)

Shelves:

  • Fusion/Correl Draw file

  • Laser cut

Door Lock:

  • Mon/Tues arrival of parts to get solenoid working

    • Get solenoid working

  • Figure out what microcontroller can handle 12V of power to control & communicate between solenoid & keypad (maybe need to do bluetooth/networking stuff w Nrf)

  • Code the keypad & solenoid so that a combo will unlock the door

Etc.

  • Figure out how to install it all

    • CAD designs

    • 3D print them

Make slideshow & video:

  • Watch previous year’s videos

  • Make it!!
