Only one day left for the final presentation! Some teams had already completed their main features and  concentrated on improving or adding new functions on them. Some teams were under deadline pressure because they met some new problems about the features of their prototype. Therefore, all groups worked very hard (some even stay up all night!),  preparing for the  show-time on Wednesday. The detail progress of the individual group is presented  in the following.


Group 1

Team Rescue had an intensive but enjoyable day. Their LEDs in the eyes shined, the perfume in the belly sprayed. After choosing the right transistor they met a frustration about the contact problem: the loudspeaker didn’t work. After checking of their arduino programs and also with the help of our teacher they solved it finally by using a second loudspeaker!  Then they were somehow relieved and could optimize their teddy bear for the show-time tomorrow.



Group 2

The “train” team has seen a little frustrated. After completing building shell with the laser cutter, they had problems with the electronic circuit,which was considered at first easy to do: The servos for popup of the Easter eggs didn’t work well. Under deadline pressure they worked all night with only two hours sleep. Thank goodness,  they finally got it! The train fulled with Easter eggs was steering for success.



Group 3

Team Togebear had an easy day. They had solved the equipotential problem with an appropriate transistor. All they need to do was putting the space spray in Togebear. Now was the cute Togebear totally alive. Maybe they tried adding some new features on them? Let’s see how would the Togebear surprise us tomorrow!



Group 4

Team Looping Louie seemed to have an relaxed day as well. They have completed all electronics and mechanic buildings after four days hard working with probably the most complicated hardware elements: sensors, motor, position and hit detection, potentiometer… Respect!

In the afternoon they tested it together with Eva and it worked so good. We couldn’t wait to enjoy the game tomorrow!





Group 5

Team Madlab made a good progress. After finishing the main features, they kept on building the additional game board with tilt sensor, which connected to Servomotors. Furthermore they pasted a large amount of  LEDs under Madlab Box, which turned on if the ball was running through it. It was not an easy job: one wire goes wrong, others don’t work.

Cheer up!




Group 6

Team Ghostcamera had a dramatic day with happy and depression. They had already completed all the technical features and started building the old-style camera box with laser cutter. In the afternoon they attempt to take a test picture, but the problem came. Because of a USB connect error, the picture couldn’t completely show up in the computer, like a true ghost picture! They had checked the USB wires connected to the arduino program but it seemed to be no problem. After a long time search they found the point: in the arduino program they wrote a delay function of only 2 second, which was too short for a USB connect.  After extending it to 5 second, it worked perfectly.




It was a long day for the final sprint.Were all the groups ready for the end presentation tomorrow? Let’s see!
