We will use the audio input part from the 8bit Mixtape synth NEO schematic for the embroidered circuit making. For the embroidery we will use the conventional embroidery canvas for cross stitch in 22 ct specs. 22 ct means 22 holes within one inch, therefore it is exactly same gap between SMD pins, 1.27 mm, so it perfectly simulate the PDB environment. However it is only my preference and I like the aesthetic, you may of course embroider with any kind of fabric.

Textile materials

The Embroidered 8 bits Mixtape Synth circuit

We will use the audio input part from the 8bit Mixtape synth NEO schematic for the embroidered circuit making. For the embroidery we will use the conventional embroidery canvas for cross stitch in 22 ct specs. 22 ct means 22 holes within one inch, therefore it is exactly same gap between SMD pins, 1.27 mm, so it perfectly simulate the PDB environment. However it is only my preference and I like the aesthetic, you may of course embroider with any kind of fabric.

steps

  1. You can draw the circuit sketch on the embroidery canvas for your own schematic design, in theory you can make very fun pattern freely as long as the connections are all correct, or you can just make a very minimum circuit layout with shortest path like conventional PCB layout assignment. However it is recommended that you should leave some minimum distant between each component so it will be easier for the sewing work.
  2. We need to solder some conductive threads onto each pins of the electronic components for the later embroidery sewing work.
  3. Sewing up the component first, and then the connections. For the connections we don't use soldering either, we simply join the conductive threads by overlapping two threads together and then wrap it with embroidery threads with some pressure, so it can be conducted.

The LEDs assembling

The soldering is flexible circuits enemy! we always want to avoid soldering in any circumstance if you try to make a flexible circuits or wearable crafts. Of course it is impossible to avoid all the soldering but we try our best. Here we are using a special type of Top LED from Osram. It was two wings in ∫ shape, we can clamp it with tweezer so the LED can be attached with the conductive threads.


Prototypes and the finish works

Examples of the embroidered circuits and LEDs arrays.
