Hi all. I've been working on a pressure sensitive stylus that will work with iPad and Android tablets, and I've finally reached the point where it's ready to go from prototypes to commercial product.
The hardware and software will be open source - commercial packaging will come with a complete schematic and circuit diagrams, and all the STL files will be available on thingiverse. To raise money, I've gone on Kickstarter. One of the rewards you can choose is a working "beta" prototype, plus the bill of materials and instructions to build your own to test out.
Please check it out:
Share and enjoy.
