DIY LED Bracelet Teaches Color Mixing #WearableWednesday


This cute felt cuff is another voyage into color by Lara Grant, the woman that brought us the stunning LED color matching brooch that you may have caught on our blog. This time she has decided to make an RGB LED the star in this educational Instructable. The design starts with conductive fabric that has been cut with a CNC machine to create a bird of four parts. If you don’t have a machine, you may be able to get a similar look with sharp fabric shears and a steady hand. Each of the pieces is ironed onto the felt fabric and then connected to the various legs of the LED with conductive thread.


The exciting part about this bracelet comes with the addition of velostat pads, which act like tiny switches. By pressing individual pads you can activate different legs of the RGB LED and affect the color outcomes. The clever bird design allows the color of the eye to change and also acts as a teacher for RGB color values; that’s what I call an awesome STEM success.

If you are interested in making your own color play cuff, check out our woven conductive fabric. Add some double-sided fusible interfacing, and you can easily iron this fabric onto your wearable. Just trim the interfacing a bit smaller than your pattern size so it will stay hidden. Have fun creating your own designs–especially when you want a little sheen. It will be a new fave in your soft circuit toolbox.
