I made five small drivers for wearable LED strips running FastLED for Burning Man.

I made five small drivers for wearable LED strips running FastLED for Burning Man. Two were still working at the end. Moral of the story - just wrap everything in plastic. But they worked well until the dust ate the switches.

Here’s my detailed write-up with schematics and board designs.

Thanks for sharing so much great info!

Thanks for the details and your thoughts.

For your LED fixtures, the green wrap stuff from Home Depot for cling-wrapping baggage works wonders.

Cling-film seems like a good idea, I’ll try it. I was mostly thinking zip-loc bags with a cable tie keeping it snug around the cable. That’s what they used for the Straightedge sculpture and that seemed to work well for a week.

It’s not very satisfying though; I feel a sealed switch would be nicer. They’re available, but they get expensive. Toggle switches with rubber covers are big and not cheap ($3) each.

Yeah, and toggle switches are likely to get bumped if in a pocket.

All I want is an illuminated, sealed rocker switch that handles a couple of Amps, takes up less space than standard switches, and mounts to a PCB.

Any suggestions where to look, coz I have yet to find such a switch?

@Jez_Weston these? http://www.digikey.com/Web%20Export/Supplier%20Content/arcolectric-1091/pdf/arcolectric-splashproof-dust-resistant-option-for-switches.pdf?redirected=1

Sadly too huge. Or rather, that’s the standard size for rocker switches (30 mm high, 14 mm wide, 29 deep), which ends up taking up too much space for a wearable.

I’d like something as small as a slide switch, which go down to 10x5x10. I could just use a slide switch, but I’ve yet to find the combination of sealed, small, lit, and sufficient current capacity.

For some of my projects, I went with wireless controls via phone, could work also in lieu of a switch. The RedBear BLE is super easy to interface with Arduino.

If I’m after something in lieu of a switch, I could just use the Teensy’s capacitive sensing with a copper pad on the outside of the box. That’d be dust-proof.

However, I’d really like to have a hard switch that just cuts the power. That gives me no worries about sleep current and a hard reset each time it is used.
