There are a handful of challenges that if solved would make our computers significantly more useful. While we are working on solving these challenges, we are limited by time and knowledge. We want to provide an opportunity and incentive to get these challenges solved sooner. Therefore we are introducing Bounties, a program that provides store credit for solving challenges.
In order to avoid too much fine print: we reserve the right to modify or cancel challenges at any time for any reason, and while we intend to reward good faith efforts, it is at our sole discretion whether or not a challenge was adequately completed. Any related repo, code or documentation must be published under an open-source license, preferably a permissive license. While some bounties may list additional rewards sponsored by third-parties, we only guarantee the delivery of Machdyne store credit for completed challenges.
Most of the challenges will require either one of the listed computers or a compatible development board. If you’re using a compatible development board and don’t have one the listed computers, we would be happy to test your submission for you.
Please feel free to contact us with any questions.
