A one-person hardware lab in San Francisco. I put sensors on things you already do anyway.

*results may vary. that is rather the point.

the story so far

  1. born at yc ai startup school. told garry tan i’d build it. out loud. witnesses everywhere.
  2. so now there’s a delaware c-corp about toilets.
  3. bought a $3 accelerometer. taped it to the handle.
  4. it counts flushes. the count becomes a number worth saving.
  5. acorns rounds up your coffee. this rounds up your bathroom.
  6. next: your bike.

the work

on the bench rn!

project 01

A flush becomes a little saved.

A sensor hides on the toilet handle you already own. Flushes get counted, and the count turns into a number worth saving. No real money moves yet. First the counting has to be boring and right.

status: a breadboard on my desk and a deadline on the internet.

not built. yet.

project 02

Signal a turn, hands stay on the bars.

A bike turn signal with no button to press. Your own gesture triggers it, so both hands stay on the bars where they belong.

current status: a concept, and a strong opinion about motion artefact.

Why hardware

habit apps die of friction.

a flush is the most reliable habit you own.
