Projects Page

This page lists a selection of hardware, software projects as well as some interesting brain-teasing exercises. The most recent ones are generally still in development stages and additional info (like photos or textual commentary) will be added as work progresses. If you find any of these descriptions useful, please let me know. (Contact me at bill dot slade at ieee dot org.) Note that this page will be periodically updated, so please check in every now and then for new additions. (If a link is not active, please be patient. I am still putting the material together!)
