Dart Hunt

In Dart Hunt, two teams compete to find, steal and horde the highest amount of darts in a limited amount of time.

Setup/ Goals:

  • Two teams each have a base at opposite ends of the floor.
  • There is 10 minute time limit to the game.
  • The team with the most darts in their base at the end of the time limit wins.

Gameplay:

  • Find the hidden darts and place it your team’s base.
  • Only Darts in the base count towards the final score.
  • The base cannot be moved or stolen.
  • Each player is given one STEAL card each. The steal card can be used to steal darts from any opponent.
  • The steal card can only be used in the predefined area in front of the base.
  • If the steal card is used and the opposing player does not have a dart, the card passes to the other team.
  • If they do have a dart, they steal the darts and the card is discarded.

The game was played on the ITP floor at Tisch, NYU.

Energy: Week 2: Pendulums and LEDS

First is our pendulum from last week:

Pendulum

Measurements of our pendulum: 1 pound, 24 inches, 2 mins:

Estimated Actual Energy of our Pendulum: 2.7 Joules

Average power of Actual Pendulum : 0.0225 Watts

Power of our pendulum over 10 seconds : 0.27 Watts

If we had dropped the pendulum from its maximum height:  

Full potential:  1 pound, 3mins, 100 inches:

Full Potential Energy of our Pendulum: 11.3 Joules

Power over 3 mins: 0.067 Watts

Power over 2 mins: 0.094 Watts

Power of our pendulum over 10 seconds : 1.13 Watts

 

For the Energy conversion worksheet we used this set up of a DC motor powered by an electric hand mixer to power an LED.  I think the motor is the same as the DC motor  I used for our wheel/ axel.

Worksheet:

Energy Converter (eg “small stepper”):  Small DC motor

Measured Open Circuit Voltage (V) : about 3 V. ( 2.92, double checked on a multimeter)

Measured Short Circuit Current (mA): about 160 mA

 

 

Kinetic circuit:

First using a DC motor from the junk shelf we hooked up 2 LEDs to a breadboard. Red LED for one direction, green for the other.

We then attached wheels to two motors and attached the motors to eachother and 4LEDS (of) to make a kinetic wheel/ spool

 

 

 

 

5 Axis CNC

Description of the fabrication method or software:

The 5 Axis CNC is similar to the 3 axis CNC we have here at ITP.  The router is attached to an arm that can move back and forth and side to side as well as up and down (x,y,z axes).  The 5 axis also has the additional ability to articulate or rotate while moving on the x,y,z axes, allowing it to access materials from an angle or from the side as well as the top.  Some of these machines also feature mobile beds which can move in any or all of the same ways as the router and arm.

Pendulum Powered

For this pendulum assignment I worked with Xuedi Chen and Anne-Marie Lavigne.  Here are some of our ideas and sketches for devices powered by our pendulum made in class:

First are the pendulum measurements:
Pendulum

 

 

1st idea:  Acme rocket launch

Have a match or maybe a bunch of matches attached to the swinging end of the pendulum.  At its lowest point it will strike a rough and combustable surface.  This will ignite the fuse on the rocket.
Pendulum Rocket

 

2nd Idea:  A pendulum powered stirrer and/ or masher.

This device uses our pendulum to drive a fulcrum and lever system.  The pendulum is on one end of the lever.  The other end will have our spoon or masher attached.

Pendulum Stirrer / Dipper/ Smasher

 

3rd Idea:  Pendulum powered camera

Using the same lever system as our second idea the pendulum operates the shutter and the film advance of a manual film camera.

Comics in class exercise

First comic for Comics class.  This was an in-class assignment to make a 4 panel comic about a physical scar.  See below the comic for more background info.

Scar Comic

 

Scar Comic

I chose to make a comic about the scar in the corner of my eyebrow.  When I was about seven years old (give or take three years…) we lost heat in our apartment for a few days. I went to sleep in a flannel jacket and a sleeping bag.  In the morning I woke up with my eyebrow caught in the zipper.  The scar is now barely visible and always forget which side it’s on.
