Just a quick little update.


Sewing with stainless steel is an interesting experience. I used super glue instead of clear nail polish to keep the fraying in check. I think that the stitching itself looks pretty good. I left the tails very long and just made large running stitches to get them out of the way (and to make sure that they didn't short to one another).



I connected the FLORA using the alligator clips to the needles still holding the stainless steel thread. Then I took this action shot.


Yes, my fabric is a little strange. I picked up some black canvas with gold-colored strands some time ago, I used it as a backing material since I had it around.


I have a few questions for the readers. My LEDs have been somewhat unreliable. I attempted to seal the contact by applying more superglue to the whip stitched pads (after a successful lighting), but the problems persist. Is it possible/good practice to solder the thread to the pads? Would some sort of conductive ink or paint be better (waterproof of course)? Is this redeemable? I am assuming here that my DI/DO connections are at fault. For those connections, I wove back and forth between the adjacent pads in a figure '8' pattern before tying as securely as I could with a square knot. If I was to do this again, I might try whip stitching one pad and then the other.


So, where are we at?

  1. Review and test parts - I'll verify that the electronics work and I will run the code from the Adafruit tutorials.
  2. LED Array - I'll take my first shot at sewing with stainless steel and build a circular, 8-NeoPixel array sized to fit in the palm of my hand
  3. Accelerometer - The accelerometer will be used to determine if I am holding my palm up or down AND to signal my LED array to turn on if I shake it hard enough.
  4. Compass - The magnetometer will be used while the LEDs are active to indicate my bearing, compensating for hand orientation
  5. GPS - The GPS unit will be used to help calculate initial bearings and possibly distance as well. I'll have to see how the device reacts to different orientations and fabrics.
  6. Physical Layout - I will have to figure out how to fit all of those goodies on the front and back of a glove (while not sacrificing wearability)
  7. User Experience - This is probably a good time to make the lighting pattern more interesting or informative, iron out bugs, test accuracy and a few failure modes.
  8. Sewing - This will be an interesting experience, I hope that local fabric stores will allow me to test the light diffusion/transmission of different fabrics I will encase the finalized electronics in. I also have never sewn gloves before but look forward to practicing. A lot. I really want to make this look like a real/well-finished product.
  9. Light Balancing? - The Lux sensor might help me adjust the brightness level for appropriate day/nighttime use.
  10. Low Power? - If I have time, I will try to see if there are ways to reduce power consumption.
  11. Capacitive touch buttons? - If I have time, it would be nice to be able to change destinations.


Just for fun: I see that Leslie is a Game of Thrones fan. I always have pictured myself as more of a Stark.


I have always thought an Iron Man / Game of Thrones crossover could be interesting.
