Our open-source micro-readerboard kit is easy to make yourself, following our detailed instructions. You don't need to buy anything (from us) to make it. However, you can buy our kit, exclusively through the Maker Shed. Complete plans and documentation for the project, as well as our super-spiffy instructions are available at evilmadscientist.com. We also have the alphanumeric display from this project available on our main LED page.
