Is it safe to show a Wi-Fi password on my arm at a party?

Only guests within reading distance see it, and you can blank the matrix instantly with a hold on Pad 5, or omit the Wi-Fi string entirely in your Sleeve Studio profile.

Can I cycle through several strings automatically without tapping?

Yes. Set an auto-rotate interval in the mode and the marquee will cycle your social, tip, and Wi-Fi strings on a timer while you keep both hands free.

How do I change the handle or tip tag after a rebrand?

Open the Sleeve Studio app, edit the strings block in plain English, and send the update over Bluetooth in about 10 seconds.

High-Contrast Social & Tip Handle Scroller on an 8×32 LED Sleeve

One tap on Pad 5 marquees your @handle, Venmo or CashApp tag, or guest Wi-Fi password across all 32 columns of the 8×32 RGB LED matrix while a small pixel badge holds the corner — sharing exactly the detail you choose on the washable $199 sleeve.

Share your handle without reciting it: One tap scrolls your @handle, tip tag, or Wi-Fi string in bright, readable letters.
Privacy kill switch: Hold Pad 5 to blank the whole matrix in one frame the moment the exchange is done.
Ships as 1 of 50 modes: Pre-loaded as Social Share Marquee; edit any string in the Sleeve Studio app.

Why Reciting an Instagram Handle Out Loud Fails at a Noisy Event

Shouting a handle fails: Spelling it out over music — or waiting while someone types it — kills a good introduction.
A lock screen over-shares: Flashing your phone shows far more than the one detail you meant to give out.
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.
