Danny Rozin Fall 2016 – ITP Physical Computing

For next week- think of an idea for your mid term project (one week projects, you can do anything you want) and be prepared to discuss the idea in class next week , make a blog entry with the idea.

Week 7 – More Serial

Schedule

Week 9 BOMs, system diagrams and time tables from previous semesters:

Tentative project schedule :

Concept – week 1 (Week 9 of semester)

To do:Narrow your ideas, make playtesting pototype, make BOM, Schedule, space and interaction diagrams

Interaction Design / play test – week 2 (Week 10 of semester)

To do: Reevaluate idea and interaction after playtesting, adjust BOM and diagrams accordingly, order stuff, learn required skills (special sensors and such)

Implementation -weeks 3-4 ( Weeks 11-12 of semester)

To do: Build functional prototype (maybe not 100% fabricated exterior)

Usability testing week 5 (Week 13)

To do: Reevaluate usability after usability test, make changes, finish prototype including fabrication

Final presentation week 6 (Week 14)

To do: Celebrate! (and document)

Week 11 – Loads

AC Loads:

Any AC load can be controlled with Arduino using a relay, including motors, fans, lights, computers,

power switch tail https://www.adafruit.com/products/268 safest and most convenient

Relay https://www.sparkfun.com/products/10924 you need to wire your high voltage through it so be super carefull

AC motors

Attributes: Cheap, strong, medium speed, hard to control speed, hard to reverse.

Geared DC motors

Attributes: Very strong, slow , you can control speed but not angle, reversible https://www.servocity.com/html/micro_gearmotorblocks.html

DC motors with encoder

Attributes: Like DC motors but give you to feedback via optical encoder
