Hi HN! This blog post is about Project Sistine, a hack that I worked on with @antimatter15, @bijection, and @logane. We turned a MacBook into a touchscreen using only $1 of hardware (a small mirror, some pieces of a rigid paper plate, and a door hinge).
We built this prototype some time ago, but we never wrote up the details of how we did it, and so we thought we should share. We're happy to answer any questions you might have about the project!
This is cool. Thanks for sharing. Its always fun to see such interesting applications of basic ideas coming together to do something one wouldn't think is possible.
We're planning on adding more instructions to the GitHub repo over the coming week, to make it easier for people to replicate our hardware setup. Among other things, Kevin's developed a slightly easier-to-manufacture version that doesn't require a door hinge.
