@jerrytron , at this point to try and see your project continue to grow and possibly reach a finale, I ask that you release the design details to us backers. I have had a great time with Choosatron up to now, but it is NOT a complete product. I backed your wonderful idea with the understanding that I would have an easy to use writing solution for my students.
I ask that you release both software and hardware details (schematics, firmware code, Write code, etc.) to the community and hopefully we - as a whole - can see this continue to grow.
With this info, I will do my best to contribute back to the community anything and everything I can to see this idea continue development.
