14. Animal Background Eurasian Lynx Facts: Found in forested areas of northern Europe & Asia. Average weight of 25 to 75 pounds. Feed mainly on roe deer, chamois, rabbits, birds and rodents. Columbian Park Zoo is home to three Eurasian lynx: Koshka (pictured), Katya & Larisa.

15. Progress Last semester’s conceptual design of a Lynx chaser track did not meet the Zoo’s criteria. Our alternatives included the possibility of a vibrating ball or laser light track. The zoo director recommended the vibrating ball for the lynx. Same focus as original project, but different approach towards goal.

Motor – Hsiang Neng, HN-GH12-1634T, 4.5 – 12 volts, high torque/low RPM.

20. Budget Total Budget: $150 Total Budget: $150 Epoxy: $5 Epoxy: $5 Hamster Ball: $4.50 Hamster Ball: $4.50 Bumble Ball: $14.50 Bumble Ball: $14.50 Boomer Ball: $55.50 Boomer Ball: $55.50 Battery & Charger: $50 Battery & Charger: $50

21. Problems with Design Problem: Movement of ball is not as sporadic as desired. Possible Solution: Alternate stop and start of motor to continually change the center of mass of the ball. Problem: An inexpensive method to detect displacement of the ball to signal the motor to start. Possible Solution: A accelerometer which would be able to start and stop the motor.

28. Game Cards and Rules Rules 1. Take turns spinning the dial 2. Wait patiently for the animal to light up 3. Check to see if the animal is on your bingo card, if it is put a rock on top of it. 4. If you get 5 rocks in a row, stand up and shout "BINGO!" (You win) "BINGO!" (You win) 5. Do not eat the rocks, even if you're hungry 6. Do not throw the rocks at your friends and/or animals 7. No Cheating! The teacher may be watching you. 8. Have Fun!
