Homework assignment

Applications and Implications

Propose a final project that integrates the range of units covered:
what will it do?
who's done what beforehand?
what materials and components will be required?
where will they come from?
how much will it cost?
what parts and systems will be made?
what processes will be used?
what tasks need to be completed?
what questions need to be answered?
what is the schedule?
how will it be evaluated?
Projects can be separate or joint, but need to show individual mastery of all of the skills where possible, you should make rather than buy the parts of your project.

Short description of applications and implications

Taken from the final project description:

What's the goal of the project?

My final project will be an individual wardrobe with smart unlocker system (using RFID or Bluetooth). It should work like this: when the wardrobe is closed - bring you id-card (based on RFID) to it. RFID card of the wardrobe's owner will open it using stepper motor. After the opening when you want to close wardrobe - just push the door - button (step end) will be pressed and stepper motor will lock the wardrobe.

Precessors

I found that before me only two people during Fab Academy (Diazdeleon Alejandra and Meier Ferdinand) made their own wardrobe. To be honest my project didn't far away from box with RFID-unlocker.

Materials and components

I'll use plywood to make a skeleton of wardrobe; microcontroller, transistor, coil and RFID-reader to make unlock system. Also I'll need some screws, batteries and wires. All parts I can buy in my city or made by myself. Total cost of parts is about ~$85 ($60+$5+$10+$10). Everything except RFID-reader and RFID-card will be made by my own. In case of time limit I'll make shield for Arduino or Galileo instead of plate with controller and transistor for coil. I'll use laser cutter to engrave my name, CNC router for skeleton creation, precise CNC for milling the circuit and 3D-printer for connectors.

Schedule of the project (tasks):

  1. Gathering of materials (30.05)
  2. Machining of the skeleton (31.05)
  3. Designing and machining of the electronic plate and testing (05.06)
  4. Assembly (07.06)
  5. Designing and printing of connectors (09.06)
  6. Final assembly and testing (12.06)
Electronics is the most complex part of the project for me - I took it into account in the schedule. I'll make a shield for Intel Galileo, transistor and RFID-reader. I already designed a skeleton of the wardrobe based on my box creator project:

Evaluation

Evaluation proccess is to test wardrobe functionality (that it can be opened as planned). Also I'll try to open it with somebody else's RFID-cards and wardrobe shouldn't be opened.
