The device that costs less than dinner - but returns a life.
L.I.P.S. — Open-source. Built by hand. Changes lives.
L.I.P.S. is a USB sip-and-puff interface for people with paralysis. An analog joystick moves the cursor; sip and puff trigger fully configurable actions — clicks, keystrokes, or scroll. No drivers, no configuration wizard. Plug in and go — then customize everything.
“The difference between dependent and independent is eight milliseconds.”
One sensor. Puff fires a left click, sip fires a right click — baked into firmware, no configurator involved. The joystick drives the cursor. Fewest parts, simplest build, lowest cost. The right choice for a first device.
The device that costs less than dinner - but returns a life.
Current commercial sip-and-puff devices on the market. Proprietary. Repair-dependent. Out of reach for most families.
Open hardware. Fully repairable. Every schematic, file, and line of firmware is yours — forever.
Prices shown are for the single-sensor version. The Dual and Plus variants cost more.
Start building →L.I.P.S. is free, open, and always will be. But certification costs money — and a certified device means no soldering iron required. One contribution brings us one step closer to a version anyone can order and use out of the box.
