Week 3 Objective
In this module, we'll explore erratic motion and art-making with an activity called Scribbling Machines. We'll also investigate how tinkering maps on to different indicators of learning.
My activity
Many models of scribbling machines were presented in the vídeos of this week and there are a considerable number of examples in the Internet.
My scribbler machine follows a common design. I've used a recycled transparent plastic container of cherry tomatões, I've used black insulating tape to attach the pen and disguised itwith decorative tape. I've fixed both motor and battery with velcro.
My propeller is made with wooden sticks covered th the same decorative tape. As the initial single stick didn't make the machine move I've added an exra piece of stick in L shape and an extra piece of EVA material to hold better the propeller to the axis motor.
Finally, I've made some decoration to make a face to the robot and put an antenna with a pipe cleaner.
Exploring other electric circuits projects I've found Yuri Ostr channel with great tutorials and I've borrowed his idea to make a mini-sander
As it was not practical to connect the wire to the motor, I decided to add a switch made of push pins at the , which works perfectly.
Electric Quiz Boards
I've made two electric boards for educational matching games.
One board is made of poliestirene, a light plastic material, that signals the right answer with a light (LED).
The other Board is made of craft K-line with a sound signal (buzzer). This one can be used by blind children adapting to Braille and embossed images.
