Nov 14th- GRNG 201's- Bicycle Stand, Aquaponics Controller

Discussed Mini MakerFaire at NNHS on Saturday 9 AM- 2 PM--please sign up for time slots for booth.

Two students will attend LearnLaunch expo at Hynes in February.

Blog posts-- focus on the quality of your blog posts!  Events force people to get something done.

Sparcwire  product evaluation--do one post every class period--list an article you found.

Complaints about quality of Sparcwire & poor presentation by the representative---much more is often learned from bad work as from good-- this is a product trying to change its market.

Provide constructive criticism.

Students worked on bicycle stand:


     
   Excessive strain(moment) on bottom connection- constructed a diagonal strut to reinforce it.



Aquaponics Team- working on fish feeder mechanism. Suggested gumball-type mechanism or feed-screw. See designs online at http://www.instructables.com/id/DIY-automatic-fish-feeder-for-aquaponics/ .
