10-minute Electronic Leather Band




We've been inundated with requests for quick ways of incorporating conductive thread, lights, and batteries in new projects and this is what we came up with.

Here, we show how to create your own electronic leather band in under 10 minutes. This band can record and playback new patterns of flashing light. Check out the movie:

Disclaimer: we make and sell some of the components on Aniomagic's website http:///www.aniomagic.com . The mimeolight is inspired by Alex Weber's Programmable LED Instructables project - https://www.instructables.com/id/Programmable-LED - and by research at the Craft Technology Lab - http://l3d.cs.colorado.edu/~ctg


Step 1: Ingredients (1st Minute)

You'll need:
- one mimeolight
- some conductive thread
- one 3-volt battery
- one leather strip
- one paper clip
- one plastic flower
- one needle (and thimble)
- 10 minutes

The mimeolight, conductive thread, and battery you can get from http://www.aniomagic.com

Step 2: Circuit Overview (2nd Minute)

Thread #1 connects the plus of your mimeolight to the battery's positive side, and Thread #2 connects the minus.

When you put on the strap with the battery between the two sections of thread, the circuit is completed and energy flows from the battery to the mimeolight.

Step 3: Mimeolight to Plus (3rd Minute)

Sew some stitches through the plus hole on the mimeolight, then work towards one end of the strap. Finish off with several wide stitches at the tip to form the plus of your "battery holder." Tie a knot and cut.

Step 4: Mimeolight to Minus (6th Minute)

With a new section of thread, make several stitches through the minus hole of the mimeolight, and then work towards the other end of the strap. Keep in mind that since the plus of your battery holder ended up on the rough side, you should now end up on the opposite, smooth side.

Step 5: Mimeolight to Minus (8th Minute)

Make sure to leave a gap between the last run and the stitches for the battery. This will prevent the conductive sections from shorting when the strap is closed.

Step 6: Finishing Up (the 10th Minute)

Place your battery, and close the strap. We used a paper clip to hold our battery tight.
We're sure you'll have a much more elegant solution :-)

    This is pretty cool. As for a better clasp, try using standard metal button-snap clasps (found on most leather bracelets) and simply have the battery mounted on the side of the band. Run the wires to the clasp and the conductive metal will complete the circuit when it is closed.

    It'd be interesting to integrate a charge transfer touch sensor: (https://www.instructables.com/id/Curved-Circuit-Board-Art-Make-a-Touchless-Touch-S/ ) so that it's only on when worn.

    You could try using conductive velcro. I got some at Lessemf. I've been using it on a number of projects and it works great!

    Any chance of an instructable that explains what the mimeolight component is?

    a thin neodymium magnet and peice of stainless steel attached on either side of the clasp would make a great connection - conductive too :)

    That sounds like a great idea! I'm going to try that. The batteries are also magnetic, but I wonder if it would be strong enough to withstand vigorous wrist motion.


    Reply 10 years ago on Introduction

    you have to be careful talking about 'vigorous wrist motion' ;) a strong magnet on steel or another magnet would be quite strong, especially if the clasp is keyed so each side engages to provide lateral strength - look at a magnetic purse catch to see what I mean.

    With just a touch of elmer's glue. The milky white glue diffuses the LED light pretty nicely. It probably won't be robust for daily wear, but it is what I found within 10 minutes.
