Can I time a darkroom step without any white light?

Yes. Hold Pad 4 to switch the 8×32 matrix to dim red only, then the sleeve runs DEV 08:30 and flashes AGITATE NOW on schedule.

Will clay ruin the sleeve?

Bump the pads with a clay-covered knuckle or elbow and hand-wash the matte-black sleeve in cold water after; the electronics slide out first.

Can it time pottery steps too?

Swipe Pad 3 to pick a Pottery profile and the same timer tracks wedge, throw, and clay-cure steps.

Pottery Wheel & Film Darkroom Development Step Timer

Wear the $199 Garment GUI LED & Touch Sleeve on your working forearm: time clay-covered pottery steps or a pitch-black darkroom development (DEV 08:30 · AGITATE NOW) on a dim-red 8×32 LED matrix with 5 conductive-fabric touch pads.

Clay- and dark-proof timing: A dim-red mode keeps the matrix darkroom-safe while a chin or elbow tap starts each step.
Washable after the wheel: The 8×32 LED pod slides out in 5 seconds so you can hand-wash clay and chemistry off the fabric.
Ships as 1 of 50 modes: Pre-loaded as Darkroom Step Timer; set dev, fix, and pottery steps in Sleeve Studio.

Why Phone, Watch, and Tablet Screens Fail at Timing Pottery and a Pitch-Black Darkroom

Clay smears any screen: Coated hands ruin a phone or tablet the moment you reach for them.
White light ruins a print: A normal timer screen fogs film, so the cue has to be dim red on your body, not on a screen.
Peer-reviewed textile roots, shipping hardware: The Oct 2026 NUS Nature paper coined “garment GUI” with a lab-only woven pixel fibre (not for sale); our shipping $199 sleeve uses 5 sewn conductive-fabric pads and a removable 8×32 LED pod.
