Project Ideas w/ LED’s and 3D Printer

My partner, Sara, and I thought of these ideas because we’re awesome:

  • 3D cat mask that lights up
  • 3D mini catapult for candy maybe
  • jack-o-lantern
  • https://www.youtube.com/watch?v=8PCp5xk-9Qo pumpkin tetris
  • key chain that lights up w switch
  • garment that lights up w/ LED strips

Top 4 Table Ideas:

  • jack-o-lantern
  • T-Rex
  • catapult w lights
  • christmas tree

Other top table ideas:

  • touch-screen etcha-sketch
  • light up Twister
  • Lightsabers
  • Impossible box w lights
  • light up trash basket ball hoop
  • light up box
  • open/exit sign

LED it up #swaggggg

(now with pictures !!)

It was nice to refresh on breadboards and LED circuits. I remembered a few things from last year, such as the positive and negative ends of the LEDs, and how to use switches. However, last year I was not very good at actually creating the circuits, so these instructional videos really showed me what I was doing wrong. In most cases, only a single wire was out of place.

In this activity, I didn’t use the video, as this was like a review from last year. I got the light to work on my first try with the use of a resistor.

Here, I had some trouble when I attempted this task without the video. As it turns out, I had only misplaced one wire, which after I corrected it worked perfectly.

In this activity, I really wanted to see how many lights the battery could power, so I used more than in the video. I used the other half of the breadboard, something I don’t usually do.

This one took some time, as I realized the LED I was using was burnt out. At first I thought it was my circuit, but after several attempts at fixing it, I tested the light with the coin battery, to find it was broken. After replacing it, the circuit worked. This activity taught me two lessons; always check that your indicator works before checking the circuit, and resistors get very hot when in use.

Cat and (Computer) Mice

meowmeowmeow

For our project, we decided to create a holder for the computer mice. Because both Sara and I are witty nerds, we decided we wanted to play off the word ‘mouse’ and do something creative and functional. We settled on a cat paw, so the claws could hook the ‘tails’ for the mice. The design was difficult, as there were a lot of curves and symmetry to account for. However, with some teamwork and bouncing of ideas, it turned out really well.
