Fast Switch on/off counts

Posted in 10. Build the Hardest Part, Brainstorming on November 14, 2009 by yuebinyu

In case anybody is looking for fast switch on/off counts, you can remove the resistor before the input pin , so the sensitivity is higher. One resistor strategy.

Also, use this style code. Together, the accuracy and speed are awesome.


Before I found this, I used the normal switch connection ( with two resistors ) to try my pedometer for half a day, the performance was very pool. Solder and re-solder, did not solve the problem. Arduino almost could not get accurate reading.

I needed to create gears for my project, and I found this nifty website that generates and allows you to test gears.


Brainstorming – Jump It/Hit It

Posted in Brainstorming on October 20, 2009 by sbisker

Our group (myself, Melissa Acoste and Anthony Zhang) chose to brainstorm an idea for the playground.

We envisioned a semi-transparent rubber-esque cover stretched out over a large rectangular box filled with springs. The cover would probably be similar in feel and tension to a trampoline, and the springs in the box would act not unlike those in a mattress. These springs would be used to detect when pressure is pushed on a particular area of the rubber cover – and when the cover is pressed, an internal projector or other similar system would cause a colored blob to appear visually where the person has pressed. The size and shape of the blob would vary primarily with the force of the impact on the springs (with some element of randomness as well.)

This screen would be movable on a large hinge into both a flat position (to use ones entire body to “Jump It”) and an upright position (to “Hit it” with parts of ones body or with objects like baseballs) In this way, we see the same item taking on totally different uses depending on the child’s choice (and some joy is derived from the simple act of moving this thing on its giant hinge).

Kids Power generator

The concept is to design a trampoline which collect the energy. While the kids jumping on the trampoline, it change the magnetic field of springs and produce electricity. The power will be stored and can be used for other need.

mti idea

our team (Rechal, Mark, Ellen) focused on a shared experience that could be achieved by co-controlling or alternative input. the former led to the idea of a bumper car in which the rider can only control the direction, while another person, riding a bike outside, will control the speed. the later, as shown in the iamge, is presented by a scream controlled pirate boat. how high the boat will go on one side depends on how badly the riders on the other side screamed. you could imagine as they get more scared, the boat goes higher!
