App support is still in progress. There is currently a demo app on the iTunes store (http://itunes.apple.com/us/app/pressurepaint/id515016023 ) and I'm in contact with a handful of developers that would like to incorporate pressure sensitivity into their notebook and sketching apps. If you have a favorite app to draw in, be sure to contact the developer (there's usually a support link in the App Store) and ask if they would consider adding support.

I expect that at least a few apps will be available when PressurePen units make their way into supporters' hands. Watch the updates page for announcements.

If you're a developer yourself, send me a message, and I'll provide you the latest source for the demo app to take a look at, and build into your own project.

Yes. You will need to be able to solder to assemble the $30 kit. All the components are through-hole, though, so there's no surface mount soldering necessary. As a reminder - you will also have to provide your own shell (STL files for 3D printers or Shapeways are coming soon).

Please add $15 for shipping outside the US.

If you plan to write in your blog or other publication about the PressurePen, or if you're an app developer that wants to incorporate pressure sensitivity into your app, send me a message. I'll be glad to send review units, once the first full batch is produced.

All review units will be marked as such, and are not for resale.
