Can it track a full 60-minute hop schedule?

Yes. Tap Pad 1 to start the boil and the sleeve counts each addition, showing CITRA 1OZ IN 04:12 until it is time to drop the hops.

Can it time a 28-second espresso shot?

Hold Pad 4 to start a green extraction bar that runs the full 28-second window to 2 oz.

Will steam or wort splash hurt it?

The sealed 8×32 LED and BLE module sit in an inner pocket; unsnap it and hand-wash the sleeve in cold water after brew day.

Home-Brewer & Espresso Barista Boil / Shot Extraction Fuse

Wear the $199 Garment GUI LED & Touch Sleeve on your brewing forearm: it tracks 60-minute hop boil additions (CITRA 1OZ IN 04:12) and a 28-second espresso pull bar, through wet hands and hot kettles.

Counts hop additions for you: Start the boil and the sleeve scrolls the next addition with a live countdown on the 8×32 matrix.
Wet-hands friendly: Tap a fabric pad instead of a splashed counter phone; the LED pod slides out for cold-water washing.
Ships as 1 of 50 modes: Pre-loaded as Dual Process Fuse; set your own hop schedule or shot time in Sleeve Studio.

▶ See the 8×32 Forearm Display in Action

Watch the 8×32 RGB LED matrix and 5 conductive-fabric touch pads running timers, kitchen, focus, health and work modes on the forearm sleeve. Concept render · simulated 8×32 display · first production run of 500 units.

Why Phone, Watch, and Tablet Screens Fail at Timing Hop Additions and Espresso Shots

Hands stay wet and busy: A counter phone gets splashed, knocked, or read at the wrong angle mid-boil.
28-second shot bar: Hold Pad 4 for a green extraction bar that runs the full espresso window to 2 oz.
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.
