Step 5Sew in Power Supply and Main Board ..... and test them!
Fast and Easy..
Clip the metal extensions on the back of the power supply.
Tailor tack the power supply in place - (tailor tacking is just small stitches with regular thread. think of it as a fabric paperclip).
With conductive thread sew the + petal of the power supply down to your garment.
Make several passes thru the + hole until you can no longer fit the needle thru.
Sew the + trace to the + petal on the Lilypad.
Again pass the needle thru the + petal on the Lilypad until you can no longer fir the needle thru.
Then sew back along your trace towards the power supply.
This will give you a more robust connection as well as allow you to knot your thread a place where it will be less likely to short circuit.
Knot your thread.
Place a drop of fabric glue on the knot.
Take a break!
Once the glue is dry then clip the thread tail.
Repeat for the - connections.
Using a multimeter, test the traces for short circuits.
Tips
I would suggest gluing velcro to your power supply and to the fabric. With this method the power supply is still removable, but held tightly in place. Place the pricky side of velcro on the power supply and the soft side of the velcro on the garment. This way if you wear the garment without the battery pack you wont stick to anything.
Do everything you can to reduce the possibility of a short circuit.
Use short neat stitches.
Place fabric glue on the final stitches to hold them in place.
And plan ahead...having to rip out your traces is depressing, but not deadly.
Right here on 'ibles there are lots of examples and directions on sewing the power supply and Lilypad. Just do a search to learn more more more.
