How To Rugged-ize Wearable Electronics #WearableWednesday
We hope you’re enjoying the summer and getting your wearable electronics out into the elements. Whether you’re making dance costumes or headed to Burning Man, here are some tips for helping them survive!
Plan ahead where your circuit boards and other components will go in your garment/costume. Position circuit boards in places on the body that don’t bend or twist a bunch, like the sides of shoes, a jacket lapel, or in the brim of a hat.
Provide strain relief to wires using glue, zip ties, or stitching.
Select LED strips and pixels with weatherproof silicone sheathing, and use silicone adhesive to seal everything up.
If your circuit might experience dust or body humidity, you may want to use thin, flexible silicone-coated wire instead of conductive thread. Soldered connections are less likely to get gunked up than sewn ones.
Sand and salt air can corrode your circuit board, and there are many ways to seal them off from the elements. Conformal coating, plasti-dip, castable plastics and resins permanently coat your circuit to keep out moisture and buffer abrasions.
Not all coatings are durable. Some break down under UV exposure. Follow the safety instructions to protect your skin, eyes, and lungs.
If you need to get in there to repair anything, you might want to go with something more temporary, or use a reworkable covering.
You can use large-gauge heat shrink tubing, tablecloth vinyl, and other planar plastics to wrap around your circuits.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
