As you may know, forum friend and robotics author Gordon McComb passed away last September. His wife Jennifer contacted me to say that she's in the process of moving and clearing out a lot of stuff, selling through her Ebay store at https://www.ebay.com/str/Meredith-Collectibles/Robotics-Electronics/_i.html?_storecat=4389767017
There are just a few things there now, and she says there is much to sell, much from Gordon's "Budget Robotics" website, which appears to be down now. It will be an ongoing process, even after she moves. IMO it's worth bookmarking that site and checking in occasionally to see what's available... she asked me to get the word out. So here's a chance to help Gordon's family and rehome some interesting pieces of robotics history.
The fifth edition of Gordon's robotics book just came out ~December, see https://www.amazon.com/Robot-Builders-Bonanza-Gordon-McComb/dp/1260135012/ref=dp_ob_title_bk
Great reading for anyone interested in robotics and electronics in general. The book has a companion site at http://robotoid.com/index.html
which is chock full of great info.
There is still some work to do that we may be able to help Jennifer with, regarding loose ends on that website. Duane Degn worked on some Arduino code, and Jennifer says there are some unfinished projects. I can't think of a better way to give back than help out in this regard. I will inquire for specifics.
As ever, God bless Gordon, Jennifer and his family through this difficult transition.
