Book Project Parts Bundles
Dave Hrynkiw
November 18, 2004
We've had many requests to sell the parts needed to build the robots described in the books that we carry. You are now able to purchase the individual components needed to build your bot, but you're not required to take them all(Sorry, no instructions -- that's what the book is for!). If you've got resistors already, no problem -- just adjust your cart accordingly.
For now, we have bundles for several of the Junkbots, Bugbots and Bots on Wheels projects, as well as two of the projects in Absolute Beginners Guide to Building Robots.
Also, check out the BEP Applications page for parts bundles for all of those projects.
