Sew Green: Sew White at #MACUL14

The Michigan Association of Computer Users in Learning (MACUL) conference kicks off tomorrow and my colleague Leigh Graves Wolf and I will be hosting a mini maker faire at our Master’s in Educational Technology booth in the MACUL exhibition hall (booth #124).  If you’re interested in learning how to create a felt badge that lights up, then stop by or sign up to be sure of a spot at the maker table: http://www.signupgenius.com/go/20F094EA5A82CA57-maet

You will also find an array of materials to help you make explicit connections between this activity and your curriculum.

How to Sew a Circuit into a Felt Badge

MaterialsSewnCircuitBadge

Two pieces of felt (Green and White, preferably)
An LED light (Green or White, of course)
A coin cell battery
A coin cell battery holder
Conductive thread [length will vary depending on your ambitions]
Scissors for cutting thread
A needle
Garden variety white thread
[long enough to sew around the badge]

Procedure

1. Put the battery in the battery holder. The “plus” side should be facing up. The plus sign should also be facing toward the “E” shape of the battery holder.

2. Thread the conductive thread through one end of the diode on the battery holder. Tie a knot to connect the thread to the diode.

3. Thread a second piece of  conductive thread through the other end of the diode on the battery holder. Tie a second knot.

4. Puncture the felt with the ends of the LED light. The light bulb will be on the outside of the badge. The two ends of the LED will be on the inside of the badge, attached with conductive thread to the battery holder.

5. Once punctured through the felt, bend the ends of the LED so that they’re flat against the felt — you’ll have to bend them down too so that they don’t stick out the sides of your badge.

6. Before you sew, check to make sure the positive end of the battery holder is connected to the positive end of the light; the negative to negative. Test this by seeing if your light illuminates when you touch the ends to the diode. You will extend this same circuit with conductive thread. Remember which end of the light attaches to which end of the battery holder.

7. Position your Battery Holder below the ends of the LED light so that you can sew the conductive thread through the felt and around the ends of the LED light. You only have one strand of thread for each end. Threading the needle with the conductive thread can be a bit tricky…but don’t lose patience!

8. Once you have both ends of your LED light sewn into the felt with the conductive thread, you should have an electrical circuit and the light should be shining!

9. Put the back on your badge by sewing it together with the other square using the regular white thread. The battery should be on the inside.

10. Once you’ve sewn it, together, attach an MAET button under the light.

You can leave the top of your badge open so you can remove the battery…but if you sew it shut, it will last many days!  The light pictured above has now been shining non-stop for six days…

And voilà! A wearable circuit that glows Spartan spirit!

How to Make a Paper Circuit from your MACUL Name Badge

This Wednesday, Thursday and Friday (March 12-14)  I will be at the Michigan Association of Computer Users in Learning (MACUL) Conference in Grand Rapids, MI. Unlike most conferences where I present sessions, at this conference, I will be at the Master’s in Educational Technology Booth (124) in the Exhibition Hall hosting a Mini Maker Faire with my colleague, Leigh Graves Wolf.

Here’s one of the activities that we’ll be doing with our MACUL Maker Colleagues.

How to Make a Paper Circuit from your MACUL Name Badge

Materials:

MACUL Name Badge
Tiny LED Light {or similar}
Tweezers
Double-sided Scotch Tape
Copper Tape
Scissors
Coin Battery

Procedure:

  1. Decide where you would like to place the light for meaningful effect. Do you want to light up the “i” in your name on your name badge? The “M” in MACUL?

  2. Plan out your circuit. Based on where the light will go, decide where to place the battery and how long your copper tape will need to be.

  3. Cut the copper tape in half. You’ll need two lines of tape, placed very closely together to make the circuit work. Plan the placement of the two pieces of tape on your name badge.

  4. To make the circuit, position one piece of copper tape so it will connect to the negative side of the battery; position the other piece of tape so it connects with the positive side of the battery. Use Scotch tape to fasten the battery to your name badge.

  5. Stick the copper tape down on your name badge — being very careful to ensure the the pieces are placed very close together. The LED light is SMALL. To get a good connection, there should be very little space between the two strips of copper tape.

  6. Place the LED light strategically. Test it by pressing it against the strips of copper tape with the tweezers. Does it light up? If not, flip the diodes.

  7. Stick the LED light down onto the copper tape using the double-sized Scotch.

  8. Voilà! You have a paper circuit and a very fancy MACUL name badge!

This project was inspired by the great things happening over at Exploratorium.edu.
