Homework
Our homework was to propose a final project that integrates the range of units covered in FAB Academy. I am an elementary school teacher about to help open a STEM school this fall, so of course I wanted to make something that we would use at the new school AND that young kids would LOVE. This school year, our favorite Design Challenges have been those that have involved racing and competition.

What will it do?

Race

Who's done what beforehand?

Dual Lane Race Timer on Pitsco.com

Dad's HotWheel Track for Son

Dad Track

What materials and components will be required?
Where will they come from?
How much will it cost?
The costs should be minimal since we should have most supplies in the lab. It should cost between $20-$30 to make, depending on what one has on hand.




BOM for Final Project
  1. phototransistors 1206--2
  2. white/yellow LEDs--2
  3. ATTiny 44--1
  4. capacitor--1
  5. 1k resistor--1
  6. 10k resistor--2
  7. 2 pin connectors--2
  8. 4 pin connector--1
  9. 6 pin connector--1
  10. ABS plastic sheets to laser...could use acrylic
  11. vinyl for vinly cutter
  12. 2 red LED pin lights
  13. 9 volt battery and holder
  14. appropriate cabling that is available
  15. FTDI and ISP for programming


What parts and systems will be made?
  • 4 legs for start/finish line
  • 2 top cross pieces for start/finish line
  • system of 5 boards networked together

  • What tasks need to be completed? (see below)
    What processes will be used? (see below)

    What questions need to be answered?

    What is the schedule?
    How will it be evaluated?

    ***My final project will demonstrate my mastery of many things learned in FAB Academy. I will use my skills on the vinyl cutter, laser, electronics design, populating and soldering components, input and output devices, 2 and 3D designing, programming a microcontroller board AND 4 satellite boards, troubleshooting, testing and retesting, prototyping, organizing and planning. Check out my Project Development page for more details!
