What I like about the Schemer system is that you can connect all its components using only two wires/threads instead of having to wire each one to the board individually. This makes for less conductive thread used, but also a more simplified design for your wiring. All the components are small enough that they will fit on fairy wings and be relatively unobtrusive. And for added fun, since the Schemer is programmable from an iPhone/iPod you can actually change the patterns while wearing it/out and about without having to hook up a computer.
Here's a video of them in action:
Step 1: Materials
* Schemer Board and 2 sets of lightboards from Aniomagic. Unfortunately the Schemer only works with Schemer compatible components, so you can't substitute regular LEDs.
* Sewable Coin cell battery holder - I am using a plastic one, but you can also substitute with a felt one.
* 3V CR2032 Coin Cell Battery - if ordering from Aniomagic's site it is the 'large' battery.
* Conductive Thread
* Needle and Cotton Thread (make sure your needle fits through the holes in the Schemer, Lightboards, and battery holder holes)
* Hot Glue Gun & Glue
Step 2: Plan your design
Trace your wings on a piece of cardboard or posterboard with a pen or pencil. Plan out your placement of components - the Schemer in the middle and Lightboards on the wings. The Lightboards connect with the Schemer using two sewn lines (one + and one -) attached to the holes on the side of the board. The top and bottom holes of the Schemer will connect to your battery holder on the back of the wings. I've attached a diagram of how I attached my components for reference.
A note on Schemer and Lightboards:
Each Lightboard has an ID number assigned to it, 1-5, marked by dots. If you have more than one Lightboard of each ID, they light up at the same time. Because of this, I used one set for each side of the wings and mirrored their placement so they would light up together. The color of the Lightboard makes no difference, if you have a '1' of green and '1' of red they will both light up together.

Step 3: Transfer design to wings
Step 4: Attach battery holder and schemer board
On the front of your wings, place the Schemer board in the middle of the felt and draw lines from the holes to the traced lines on the wings. The top holes are your positive and bottom are negative. Attach the Schemer by sewing a line from its top hole to the edge of your felt with conductive thread.
Fold the felt over and continue sewing to connect the thread to your battery holder. Loop the thread a few times to make a secure connection. Repeat for the bottom hole on the schemer and the other side of the battery holder.
Step 5: Attach lightboards
Work your way around the top wing. When you reach the edge of the top wing, carefully push your needle through both layers and continue the line to the bottom wing.
After the positive lines are sewn, repeat with the negative lines until all your Lightboards are secured. The two wings do not need to connect with each other, only with the Schemer board.
Step 6: Test and program schemer
Put your battery in the holder and test it out. There should be a default pattern blinking along the Lightboards.
If everything is working correctly, start programming.
Go to the schemer page.Help programming Schemer can be found here.
Press the touch pad for 1 second. The onboard light will flash 3 times, then turn off.
Put the ambient light sensor in front of the yellow flower.
Hold it still until the web browser finishes sending the program.
You'll need to hold your wings up to your computer monitor to program them. On my laptop I had to tilt the screen backwards a bit to get the Schemer aligned with the screen correctly. You can also use your iPhone/iPod to program it, which might be easier than holding the wings up to the screen.
Step 7: Finishing touches
Make a back cover for your battery holder to protect it and add some padding for when you wear the wings. Sew your second felt circle to one side of your top felt circle and sew a bit of velcro on the other side to make a flap.
Insert the battery and close the flap when you are ready to wear them.
If you don't like the look of the bare components, you can add decorative flowers or fabrics over them, letting the light shine through. You can also insulate your conductive thread with some puff paint if desired (Lynne Bruning has an Instructable for this technique). Make sure to leave access to the schemer, as the on/off button is in the middle of it, and the light sensor needs to be unblocked for reprogramming.
