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

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

Background – V-cycle ______________ Our Solution Make videos! 2

Product Design ______________ Product Design 3

Product Design – Structural ______________ Front and Back Platforms Simulate your design! 4

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

Product Design – Mechanical ______________ Gravity Assist Known Fact: Gravity is omnipresent! 6

______________ 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

Product Design – Electronics ______________ Electronics Systems 8

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

Product Design – Usability ______________ 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 10

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

______________ • 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 12 have accomplished at the end of it.

Questions ______________ Questions? Good Luck! 13

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 • lma 3@sfu. ca • http: //www 2. ensc. sfu. ca/~whitmore/courses/ 14 ensc 305/pdf%20 files/Warning. pdf

______________ 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. 15
