1. ___________________________ V-Cycle Pro Virtual Bike Simulator ENSC 440/305-Spring 2010 Project Flashback by Lukas-Karim Merhi Feb 19th, 2013

2. ___________________________ Goals and Objectives 1 Background – Goals Using your own bike indoors to enjoy a realistic cycling experience Achieved Simulate terrain, elevation and resistance.Achieved Tilting and turning capabilitiesAchieved

3. ___________________________ Our Solution 2 Background – V-cycle Make videos!

4. ___________________________ Product Design 3

5. ___________________________ Front and Back Platforms 4 Product Design – Structural Simulate your design!

6. ___________________________ Tilting Mechanism Product Design – Mechanical 5 The solution already exists and will probably be simple!

7. ___________________________ Gravity Assist Product Design – Mechanical 6 Known Fact: Gravity is omnipresent!

8. ___________________________ Lesson 1: Do not be lazy: try to read as much documentation of your components as possible Read the RUBRIC that Steve shares with you 7

9. ___________________________ Electronics Systems Product Design – Electronics 8

10. ___________________________ Lesson 2: Safety Design Electronics enclosed in a grounded box Fuse protection on power components Insulated wiring and warning signs Product Design – Safety 9

11. ___________________________ Lesson 3:Versatile Design Stand Alone Mode (no software) Active Mode (software interface) Tilting can be mechanically disabled Modular Design – 3 main components (back and front platform, control box) – Set of cables (2 serial, 1 USB, 1 Power) – Easily disassembled Product Design – Usability 10

12. ___________________________ Lesson 4: Sustainability Use of recycled materials – Scrap wood – Scrap metal – Left over fasteners – Old popped bike tubes – Reused electronic components Product Design – Sustainability 11

13. ___________________________ Lessons from the group members Dan: My best lesson learned is to design all systems for testability. We always gave and accepted honest and critical feedback between ourselves on design decisions, never fighting because we recognized that open and honest communication would build trust in the group and result in a better overall product. Jack More planning also should have been given to acquiring proper tools for metal working, especially a drill press Lukas: Arduino microcontroller: it turned out to be a great development tool especially with its open source platform, multiple analog and digital pins, serial communication, and headers for attaching custom made prototyping boards. I learned to always ask if I didn’t understand something and that making mistakes are essential to any learning experience. Mike I have seen a few 440 demos and was always disappointed. It seems that students work for hundreds of hours on their projects and then demo in a room with a couple friends, the instructors and a closed door. It seemed depressing to me that you can spend 5 years of your life in an engineering program, and no one cares what you have accomplished at the end of it. 12

14. ___________________________ Questions? 13 Questions Good Luck!

15. ___________________________ T.A office hours Room: ASB 8828.1 – (take the stairs down from Lab 1 and it is your left) Tuesdays: 1:30 to 3:30 pm – (will email if cancelled) More office hours will be announced at a later stage lma3@sfu.ca http://www2.ensc.sfu.ca/~whitmore/courses/ ensc305/pdf%20files/Warning.pdf 14

16. ___________________________ 15 Final Words In the last few weeks of the semester, live a little beyond your project. Take a break. Go out for dinner, go to a movie, have a beer, have a pop, take a walk, take a hike, and ski back down. Project courses can steal your life. Steal a few hours back.
