So here's the thing, it's occurred to us that many of our readers have come on board recently and have missed out on a lot of great articles and projects from earlier times. Being the generous types that we are, we've hand-picked some of the popular, too good to miss, projects and features that might have escaped notice. We're posting the complete articles on our website and then sending, direct to your inbox, this neat little newsletter to link them directly to you. Cool right?  We'll probably throw in some new stuff too, now and again, and maybe even a few surprises.
So, if you see something you like, enjoy it guilt-free. Consider it a gift, no charge to you. Just a perk of being part of the Nuts & Volts/Servo family. Of course you can also pass it along to a friend, if they might be interested too.
That's it, enjoy!
