Step 5Assembly Rev 2
Lay the multi-colored fabric over each other and cut a out a square, it doesn't have to be perfect. Iron the fabric to get any folds out, layer them on top of each other again and make sure the edges all match. Cut any edges that don't.
Cut the top and bottom round, leaving the left and right sides straight. You're going to invert the switch after sewing so don't make the rounded sides too round and leave enough height on the flat sides to push the switch through easily when you're done. Round out the flat side of the first and last switch.
Head on over to your sewing machine and put two of the rounds together so that the good side faces each other and sew a seam on the flat parts.
Once the tops of the buttons are sewn, cut squares out of the conductive fabric and fuse one side. Cut wire to length and strip one end. solder the wire around one of the eyelets. (the solder will not likely stick to the eyelet) Cut a smallslit in the fabric at one corner and hammer the eyelet to attach the fabric and wire. remove the backing from the fusing and fuse the conductive fabric to the back of the colored fabric. Repeat for all the switches. To make things easier, you can heat shrink tube the wires together whenever one wire passes the the wire for the next switch.
Get or make a piece of fabric the length of the switch set and cut a strip of conductive fabric the length of it. Unlike the colored switches, this is one long piece. This will be what the buttons touch to make the connection. Cut a small slit and attach a wire to it with an eyelet, like the colored switch tops. Fuse it to the back of the bottom fabric.
Sew the top and bottom together with the conductive fabric facing out, use a yard stick to invert the set after it's sewn.
Cut a few small holes in the batting, I used a chopstick to get a circle then just remover the chopstick and make the cut. Cut them to shape and insert them into the switches. This is what holds the conductive fabric apart.
It may be easier to insert the batting while you are inverting the switches instead of after. The stuff I used tore up pretty bad while I was inserting it and I had to get different batting.
Finally hook the wires up to the target board and you're all set. The long bottom strip will be ground.
